Still at it

Hello everyone!  Yes, it has been quite a while since our last post.  Actually four months and seven days to be precise – life has been full!!.  Work on the house has been progressing, but less quickly since Mike has gone to work full time on another house in Guilford.

We were grateful to have a visit from the Grandparents back in April who lent many hands.  With our exterior insulation and rain screen vent channel behind the siding to come, we needed to box out all of the windows and the doors.  So we spent a couple days milling some old cedar boards Mike did a work trade for many years ago.  We lined the bottom piece of the box with aluminum and pitched it down by about 14 degrees.

It was a bit of a bother getting a couple of the boxes to align properly because of the inconsistent thicknesses of the sheathing boards, but it wasn’t too bad.  We attached the boxes with simple angle brackets from Simpson and some exterior screws.  They will get caulked to the window with a good exterior caulk.

IMG_4890

 

We got another flock of chickens from some folks in the area who were downsizing!  Welcome to the homestead girls (and guy)!  Reason # 7008 I love having a hatchback!

IMG_4897

After we finished installing the window boxes, we were able to start installing the 3 x 4′ sheets of Roxul ComfortBoard.  Roxul also makes larger sheets which I tried to get but was told they are only sold by the truckload.  Since then I’ve talked to a local builder who used the larger sheets and said they were actually a pain because they were too big and would break when being carried to be installed.  So if anyone’s out there thinking of using these boards on a wall, go for the 3 x 4 sheets.  Maybe the larger ones would be well suited for under a slab where they don’t need to be hoisted up a ladder and held in place……

IMG_4898

I really liked how easy it was to get tight joints with the Roux at adjacent pieces and around openings.  Much more so than with foam board in my opinion.IMG_4899

 

Lapping all of the seams between the two layers.   And here you get a good look at the brackets we used to attach the window boxes.  Also note the screen above the window boxes to keep bugs out of the rain screen.  Screen is also installed at the bottom of the wall for the same purpose.IMG_4906IMG_4907IMG_4908

On the west side we plan to have a porch and porch roof some day so we are installing the roof ledger now.  I was flummoxed about how to best install the ledger without getting into complex flashing details.  Then our energy consultant through Efficiency Vermont made a great suggestion.  We used 3″ PVC squash blocks beneath the ledger and really long (10″) timber lock lag screws.  They were cut to the length of our insulation plus strapping (4 ¾” in our case).  But the genius was in how to install the squash blocks. We bought an automobile oil filter remover for a drill (about $10) and screwed the pipe lengths into the roxul!  This way there was still a plug of insulation inside the pipe.  It was a little tricky to get the hang of on a ladder, but I did and it worked well.  I’d definitely do it this way again.  I guess the only caution is that the drilling doesn’t go too deep and too long so as to rip the mento WRB under the Roxul.

IMG_4934

 

In the drill setup below  I used a hose clamp because the device wasn’t gripping the pipe well enough without it.  Here’s a quick video to help you see how it works.IMG_4935

The finished ledger.

As I think I noted before, we had trouble last winter with our foundation insulation cover/flashing of aluminum heaving up with the frost.  This caused water to infiltrate through the bottom of our sliding door.  So we had to pull the door and re-do the sill flashing.  Previously we were relying on a slight slope towards the exterior (which was reversed by the heaved flashing).  This time we added a lip on the inside of the flashing in addition to a slope towards the exterior.  It hasn’t leaked since! (thank goodness).  At the same time we removed the soil all around the perimeter of the flashing down to the wing insulation to rectify what the frost heave pulled up.  We pressed the flashing back down to ensure we had positive drainage away from the building and then used long fasteners to attach the flashing to the foundation.  We then backfilled it with crushed stone to ensure that we would not have any more issues with heaving of our foundation flashing.IMG_5023

Ella’s helping to re-grade the soil after we backfilled with the crushed stone.  IMG_5113

Here are some photos of the exterior presently.  We’re ready to do the siding, but at the moment are focusing on the interior work.  We’re hoping to be able to move in for this winter so the siding is on the back burner for now.  Note the insect screen at the bottom of the roxul ready to be tied in with the siding.  IMG_5210IMG_5212

Inside we’ve been working on finishing up the last wiring details, light locations, and installing drywall!  How exciting!  Drywall has an amazing capacity to change the feel of the room quickly.  In the next photo we show off our fancy sound deadening trick.  Glue drywall scraps between the studs.  Helps reduce sound transmission as well as keeps them out of the landfill.  IMG_5214

At the moment we’re leaning towards doing a lime plaster on most of the wall/ceiling surfaces.  I’ve been really impressed with what I’ve been learning about lime and the cycle of it’s use.  IMG_5216

Here we’re getting ready to put the last sheet on in the kitchen.  It’s kind of hard to tell, but there’s a pocket door in the left side of this wall.  IMG_5237

That’s it for now….

Out with the ladder, here come the stairs

In the past weeks, we’ve completed most of the wiring.  It is actually pretty easy to run wires with the service cavity because wires slip underneath the 2×3’s rather than needing holes to be drilled through all of the studs.  However, we did still need to drill through interior partition walls and joists.  Here’s a shot of many wires coming into a switch box at our main entrance.

IMG_4818

We built a utility room in our bathroom for …. utilities.

IMG_4814

Here’s our main AC panel.  We will probably have another smaller panel for DC loads.  The switch box to the left with the 18ga wires hanging from it is the control switch box for the Lunos HRV’s.

IMG_4816

We also framed out a half wall which will enclose the alcove tub.  Our vanity will be on the other side of the half wall.  In the floor can be seen the recess which we hope will accommodate the tub’s trap… fingers crossed

IMG_4815

The largest project of late has been creating the stairs.  We’ve decided to make a housed stringer stair.  A typical stair is built with rough stringers (usually a 2×12 with triangles cut out from it) and then trimmed out later with treads, risers, returns, and skirts.  But Mike likes the housed stringer style of stair because the frame is the finish.  The structure and the finish are all done at the same time – what you see is what you get.  We bought some 8/4 ash for the stringers, 5/4 maple for the treads and 4/4 maple for the risers (from Bradford Woodworking in Northampton and Forest Products Associates in Greenfield).  Mike milled it all down in the living room.  The hardwood supplier says there is a glut of Ash at the present time due to the emerald ash borer….. we may not have this tree much longer if things progress like this – could the ash go the way of the chestnut???  I hope not!

The stringers:…. Nice Ash you have there!!

IMG_4811

The soon to be treads and risers:

IMG_4812

There are a couple of ways to build winders, but the simplest seemed to be to build triangle boxes and then trim them out later.  It is also possible to build winding housed stringer stairs – maybe next time.

IMG_4813

Two pieces of 5/4 maple about to be glued up for a tread.  I really appreciate biscuits for an application like this.  Not only do they add strength to the joint, but they help immensely with alignment during clamping.

IMG_4819

Dry fit passed and ready for glue

IMG_4821

All glued up and clamped.  checking for flatness.

IMG_4822

If you can produce a nice tight joint, lots of clamps aren’t necessary.  I like to set the boards vertically after clamping and let the glue run down the seam for about 10 mins.  By then the glue has just begun to get a little firm.  It scrapes off nicely and then I give a quick wipe with a wet rag and the joint is left clean.  Leaving substantial glue on the joint can wreak havoc on your planer blades afterwards.

IMG_4823

One of the many reasons I love this time of year is that our swales fill up with water.  This gives a nice long drink to our fruit tree roots as they unthaw.

IMG_4825

Ella’s excited for the garden this year, too!

IMG_4829

We managed to find a few hours to boil a bit of that sap we’ve collected.

IMG_4835

Now- back to the stairs – laying out the stringers.  I took great care to get it right here to ensure a smooth install.

IMG_4836

The jig is clamped and ready to go (putting the router to good use, Peter!).  A couple of good resources for building housed stringer stairs:

Great book on making many types of stairs including housed stringers.

IMG_4838

After the treads and risers were routed out, we needed a rabbet on the bottom edge for the drywall.  It will be screwed to the the bottom of the stringers, recessed into the rabbet on both stringers – hiding the underside of the treads and risers.

IMG_4839

Our perimeter drain has been active these past days with all of our melting snow and rainfall…. a convenient place to wash one’s hands.

IMG_4843

Here we go – after MANY hours of planning, milling, measuring, marking, routing, and cutting it is finally time to glue it all together!  The treads and risers are connected to the stringers by wedges and glue.  When the wedges are driven home, they are not coming out!  They are really tight!  It is definitely not ideal to use two clamps together like this, but we are lacking in long clamps so we made due.

IMG_4848

After installing the top and bottom two treads to keep the whole thing together, we heaved it into position.  Light is not a word I would use to describe it.

IMG_4849

wedges and glue driven in from behind.  It is not shown here but we used pocket screws to connect the top of the risers to the bottom of the treads.

IMG_4851

The finished stair:

IMG_4852

Really happy with the way everything went together.  It all fits nicely.

IMG_4853

That’s the big excitement around here.  Tomorrow we will begin applying the finish to the stairs so that we can use them.  We decided on Vermont Natural Coatings’ floor finish.  it is a Whey based clear coat designed for floors.  We’re not sure when we will install the treads and risers on the lower winder stairs – probably when we install the flooring in the kitchen (it will also likely be hard maple).

As the days turn warmer we plan to move outside and begin installing the exterior roxul to the walls and building the window extensions to go with it.

Ella is excited for spring!

IMG_4809

decisions, decisions

In the past weeks we have mostly been making decisions.  Though we have also been erecting interior partition walls and deciding about light and switch placement, the decisions are the most challenging aspects of our build at the moment.  Ella enjoys helping to hold things.

img_4704

Nika was feeling like the ceiling in our bedroom was a little too flat…. so we took it down and cut a curve into it!  Kinda looks like a whale’s rib cage installed up there.

img_4743

We made a pattern that felt good to us and then traced it out onto the others before cutting it with a bandsaw.  We could have cut these pieces from a single 2×10, but the sides would have been rather brittle and weak.  So we used the existing 2×4’s from the old ceiling and added another short section of 2×4 to each end.  Then we cut the curve to the whole thing.  Because we are installing drywall atop them, the don’t need to be perfect.  ⅛” is close enough.

img_4752

Making good use of my grandfather’s band saw!

img_4744

The internet says that a ½” sheet of drywall will bend to a 10′ radius.  ⅜” drywall will bend to a 7′ radius and ¼” to a 5′ radius. Ours is just about 7′ so we chose ⅜”.  The internet also says it helps the bend if you wet the back of the sheet – so we did that.  It bent quite easily, no cracking.  It was a challenge to lift it, hold it, push it to conform to the bend and screw it all at once for the two of us, but we managed.  Then we put in A LOT of screws.  Probably about every 2″ along the ribs.  Oh and we also decreased the rib spacing to 9 ⅝” on center.  It worked quite well.  I’m excited to see it after mudding and taping.

img_4760

It’s been quite warm around here…. which means that the sap is flowing!  We’re not sure if we’ll have time to boil any syrup, but our three taps have been giving us a steady stream of sweet refreshing sap to drink.

img_4720

One of the other odds and ends I worked on in the past weeks was installing the duct for the vent fan.  It didn’t get done before insulation (which would have been easier).  But we were really impressed by the self-supporting nature of the cellulose.  This picture is looking up the rim joist insulation (at the bottom of the carved away bay is the top plate of the wall with joists on both sides of the carved away insulation).   Though gravity is doing it’s thing, the insulation doesn’t fall down.  No settling here.

 

img_4732

Ella is getting her fill of snow before it all melts and runs into the stream…

img_4737img_4739img_4740

This next picture is very exciting for me to show.  It is of our perimeter drain discharging water!  All that time we spent installing it and carefully pitching the slope has paid off!  The water table is very high will all the melting snow and rain we’ve recently received so it has been flowing for the past three or four days.  I am so glad it works!

img_4745

We’re going to keep on with our electrical wiring.  If the warm weather continues, we will most likely begin installing our exterior roxul board so that the shingles on the outside of the walls can come next.

Insulation and airsealing

As you may expect, we have been busily chugging along on what we affectionately call “the big house” which is in direct correlation to the space we currently occupy “the tiny house”.  After our holiday vacation, we returned to the dusty work of blowing in the cellulose.  To prep the space, we stapled up Insulweb with upholstery staplers.  Once the blowing began, it went pretty quick.  It took about 2 ½ days to do the blowing.  Our roof being 17.5″ thick took a little more work.  I think that Whip (our insulator) made three passes into each bay to ensure that the proper density was reached.

Our insulation, like many of our favorite things, is made in Quebec!

img_4609

Here is the machine with a bag ready to be broken up and blown into the shell:

 

img_4610

It was difficult to estimate the exact amount of cellulose needed – I overestimated and we had 100 bags left over!

In the next picture, you can see the Intello billowing out after the cellulose is installed behind it.  It is definitely a good idea to not space the strapping (or framing if you’re blowing directly behind the Intello) larger than 16″ oc.  We had relatively few staple pops which we were glad for.  Friends of ours did 24″ oc spacing and because many staples popped, they had to put a dab of caulk atop of every staple to ensure the airtightness.

img_4612

In this picture, we are in the process of blowing.  Some wall bays are done, some are empty. The cavities between the floor joists have been initially filled from above.  He then came back and inserted his hose from below the joists to bring the density up.

img_4613

img_4652

Ella named me the “dusty man”

img_4655

After installation, we vacuumed everything!

img_4689

And most of the wall bays, because they are 24″ oc, needed to be rolled flat.  It is normal for the cellulose to bulge during blowing, but when rolled with a roller it flattens out so that sheetrock, or in our case, strapping, can be installed atop the studs.

img_4691

Then the air sealing fun started.  Our primary air barrier is an interior one on the inside of the wall studs (the Intello).  This means that we want to seal every crack and crevice as best we can.  We tape all seams and use an acoustical sealant (tremco) around all window and door penetrations to minimize air leakage.  Around windows we used Pro Clima’s Profil tape.  It is a very nice tape to work with.  It has multiple sized release strips on the back so it makes it very easy to tape in tight corners like from a window frame to the rough opening frame.  We have been really impressed with the ease of workability and the tenacious adhesion of the pro clima tapes.  They are top notch!  (with one exception – the extoseal.  It gets a little thin when stretched.  I have never used DuPont Flexwrap, but would try it and see if I like it better than the Extoseal)

img_4693

Here you can see how we taped around each joist to obtain a complete seal.

img_4692

 

Once we finished with the air sealing, we needed to make a major decision about the layout of our kitchen.  To help us visualize it, we made a life size mock-up with clamps, 2×4’s and saw horses.  It is the best way to quickly get a feel for the finished space with different options.

img_4684img_4685

Then the next task at hand was adding interior partitions upstairs as well as framing out the ceilings.  Here is our solatube capturing lots of light!

img_4686

Upstairs partition wall…

img_4687

One traditional difficulty with keeping the integrity of the internal air barrier comes from electrical boxes and wiring.  It is difficult to seal all electrical boxes when they are installed in the traditional fashion.  To solve that problem, it is recommended to add a service cavity on the inside of the air barrier.  We’re adding 2×3’s to give us a 1.5″ space for boxes and wires and some plumbing pipes (larger pipes will require a larger space that will be hidden behind cabinets…. later).  Wires can be slipped behind the 2×3’s in the middle of the bays by compressing the insulation a little..  This wall is ready for wiring and then drywall (with the exception of one 2×3 at the bottom of the window)

img_4694

We’ve also been framing the knee walls at the edges of the room.

img_4696

Our next projects are to continue with service cavity installation downstairs, build stairs, and begin wiring… We’ve also been working to design our solar PV system.  There is a lot of good information on the web about it, but we would like to consult with a PV professional about a few details.  If anyone knows of someone in the Brattleboro/Greenfield area who could do some consulting, please connect us!

A door and a vacation

 

We bought a sliding door panel at a re-used building materials store in Springfield, MA for $50.  After drilling the holes for the knob and mortising in the hinges, it works great.  Eventually we plan to build our own door, but with so much to do it is not near the top of our to-do list.  This will suffice until then.

img_4513

 

img_4521

Ella – apprenticing as a fish

img_4451

To begin our cellulose prep, we isolated our rafter bays by stapling strips of insulweb to the sides of the rafters and the 2×4 bay extensions.  Our cellulose installer recommended this to help the installation go quicker.

img_4515

Our friend Amanda came back to lend a hand for a few days, which was most welcome!  Our cellulose guy, Whip, lent us some upholstery staplers which make this go much faster.  It’s kind of like a turbo fire stapler.

img_4511

We will install a strip of insulweb about 30″ wide across the roof plane where the two sheets of Intello meet.  Then we will let the edges of both sheets flap down, exposing the insulweb below it.  The hose for the cellulose will be inserted through the insulweb.  After the installation is finished, the edges of the Intello will be folded up and taped.  This saves much hole patching in our Intello by reducing the amount of cellulose hose insertion points.

img_4516

 

Below you can see the strapping which holds up the flaps of the Intello edge and also secures the insulweb beneath it.

We’ve had a beautiful Bard Owl that’s been hanging around our field looking for prey.  Here it is perched upon our Bison Pump on our well.

We’re on a break to celebrate the holidays with our family but look forward to blowing in the cellulose next week.

almost sealed up

 

It has been very exciting to be installing our windows!  We’ve been really pleased thus far with the InLine Fiberglass windows.  I don’t think they are the highest quality window that money can buy, but they are a good quality window at a reasonable price.  Purchasing direct from the manufacturer (in Toronto) helps keep the costs down.  We ordered high gain glass (high SHGC – not Low E) on the south and east windows so the sun will heat the space.

 

The fiberglass frames are quite rigid which allows for a more narrow profile of the frame.  And the research we did showed that fiberglass expands and contracts at a very similar rate to glass as the temperature changes.  That means that over time the seals are likely to stay intact when compared to other window frames.

The casement hardware is quite nice and seems like it will last a long time.  We chose casements because they close tighter than double hung windows and are more airtight.

Here our sliding glass door awaits installationimg_4411

Our friend Taylor came over for a few hours to help install our big windows and the sliding door.  Another friend, Chad was generous to let us borrow his window installing suction cups that made lifting these heavy handle-less frames easy.

img_4413

Two big ones in…. and now for the slider.

img_4421

We took a side trip to Northern Vermont for Nika’s citizenship test and on the way stopped by to see some friends at Knoll Farm.  Here is there beautiful water temple yurt and the surrounding countryside.

img_4403img_4404img_4405

The other big news is that we had our cellulose insulation delivered.  420 bags or 10,500 pounds!  Luckily the brought the boom truck which conveniently dropped the pallets just outside of our door.  All that was left for us to do was stack it inside.  img_4425img_4426img_4427

A veritable mountain of insulation

img_4429

We are hoping to get the cellulose blown in before x-mas, but this is the busy time of year for insulators so it depends on when other jobs are finished.  Our hope is that once the insulation is in, the house will keep itself at a base of about 50 degrees without any additional heat source (other than the sun coming in through the windows).

img_4401

Perimeter drain and Windows

I’m not sure which is more exciting – the perimeter drain or the windows.  The perimeter drain may not sound exciting to talk about, but it serves an important function – keeping the concrete slab/foundation dry and unable to heave from frost – very important.  But I can say for certain that it is not much fun to put in.  I’d rather be installing windows any day.  But we had to get it done.  Here you can see our filter fabric wrap (before we fill it with crushed stone) and the horizontal wing insulation coming out away from the house to meet the drain.  It is sloped away from the house so that any water migrating down through the soil will flow into the drain.

img_4380

This is a very exciting picture – connecting the loop of the perimeter drain.  It meant that we were done digging the trench!  Here I want to give a huge thank you to Amanda for detailing all of the depths of the utility pipes around the perimeter of the building which affected the height and slope of the perimeter drain.  It was way more complicated than I imagined…. thanks Amanda!!

img_4384

We placed all of our roxul scraps from insulating the slab under the horizontal wing insulation to give us a few extra RRRRs.

 

img_4382

Getting ready for backfilling – YES!!

img_4386

Ella’s hiding from the dreariness of installing the perimeter drain.

img_4383

After finishing the perimeter drain, Mike took some time to help our neighbors Taylor and Emily raise their timber frame workshop/office building.  What fun!  Taylor designed the building and cut all of the joints traditional mortise and tenon style like humans have been doing for hundreds of years.  No nails – only wooden pegs!  Yes, craftspeople were making wooden buildings before steel was widely available.

img_4390

In these next few pictures it may be difficult to make out, but we cut a nearby hemlock tree to act as a gin pole which we lashed to large trees not far away.  Then we attached a block and tackle to the top of the pole, secured the pole’s bottom in a shallow hole in the ground and erected the pole.  This allowed us to lift the whole king post truss as one unit and lower it into the prepared mortises.  The whole truss weighed something in the neighborhood of 1000 pounds!

img_4391

img_4392

Taylor and Emily tacking a hemlock bough to the truss for good luck.

img_4393

And back at home, we’ve begun installing our windows – yippee!  We decided to go with Inline Fiberglass windows which are made in Canada.  Fiberglass is a highly durable window frame which has a rate of expansion and contraction very similar to that of glass which lends to the durability of the unit as a whole when compared to Vinyl.  Because we purchased the windows directly from the manufacturer, the price for these triple paned windows was very reasonable – around $40/sf with a U-factor of about .19img_4397

We’ve also accomplished the majority of our backfilling and grading the soil away from the building.  img_4396

Backfilling was a little tricky because of our desire to have gardens close to the house.  When digging down, we didn’t want to just remove the topsoil when excavating.  That would have left us with clayey subsoil on the top.  We have a significant clay hardpan 18-24″ below grade.   So we moved the topsoil aside, removed a sufficient depth of subsoil, then replaced the topsoil.  It added an extra step and a few extra hours on the tractor, but our gardens will be happy.

img_4395img_4394img_4399

Now we’re dreaming of Insulation….. Mike has been talking to a cellulose installer who we are working some details out with.  Hopefully we will be insulated before x-mas.
