Digging the Foundation Footing

The lot we have is fairly sloped and was going to require a fair amount of fill in the south east corner of the building.  When I stood at the location of the the corner of the house after the hole had been dug, I realized that with a 4' frost wall, backfilling the rear yard would be impossible.  We therefore opted to step the footing and backfill to 4'.  The foundation wall will then have about 3.5' exposed.

In any case, the wall would have to be stepped and stepped in several places.  Armed with our plan we had the surveyor mark the foundation corners.  We started digging and taking grades with the transit as we went.  The digging went smoothly.  all the rock that we brought in for the pad was excavated and placed in the centre where it will be used to fill in the foundation for the slab.

The footings are now completely dug out and have been "tracked in" using the excavator.  Tomorrow I will tamp the footing areas for a couple of hours so we have a good stable base for the footings.  The surveyor will mark the final positions for the foundation and we will start forming for the footing on Wednesday....weather pending!

Building the Air Tight Barrier: Door Flashing Details.

It took us a while to wrap our heads around the door details on my plans.  The main exterior wall is composed of 2x8s.  The rough stud opening was substantially larger than the door.  Because the walls are much deeper than a standard door frame for a 2x6 wall, the interior of the 2x8 opening was studded with double 2x4s.   Outside of these 2x4s, there is 1.5" of foam and another 2x4 on face which brings the door frame opening flush to the exterior 3" of EPS foam.  The brick mould of the door will sit against the exterior of the wall.  The ganged 2x4s which define the opening will allow the door to open a little further than that of a 2x8 wall.    With the door details finalized, I had to flash the opening as per the plan.  I specified the size/shape for aluminum sill pans and CBS Eavestroughing made them for me.  The sill pans have a kind of end dam to prevent water from entering under the under the stud opening should the door ever...

Alot has happened....The greenhouse is now complete! The Three year project is now Done, Done and Done.

So.....A lot has happened!  The greenhouse is now complete!  My regular blogging frequency prevented me from making headway with various projects.  It was a very busy spring, summer and fall in 2019.  Working, planning our crops, maintaining a vegetable garden with weeding and regular succession plantings, and building a greenhouse all proved to be an exhausting task.  Funny, foreseeing all of the other stuff to be done, I was on the fence about building the greenhouse this past spring, but decided at the last minute I would move ahead with the project.   Now that it is finished I am glad that I did.  It turned out to be a great project with great dividends. The Greenhouse Unfortunately for the readers, I don't have many pictures to share illustrating details for air sealing, insulating, or how I designed the air barrier, or how I vented the rainscreens and roof...but I do have results!  Growing in an insulated subterranean environment do...

The Attic: A hatchway, A Landing and a Catwalk.

  Attics are one of the neglected spaces in the our homes....an afterthought really.  Many trusses are designed the same way they were years ago.  There is no thought put into the lack of insulation above the top plate on exterior walls.  Heeled trusses were developed as a solution to this problem (https://www.apawood.org/raised-heel-trusses).  Adding a small heel enables deeper insulation over the top plate of exterior walls and helps prevent thermal short circuiting to and from the attic space.   It seems that heel trusses may become a mainstay for the future since new code changes now required attics to be a minimum of R50.  Large heels mean more blocking and higher baffles to combat the effects of wind washing on the thermal effectiveness of the attic insulation.  The key here is to direct any wind (entering the attic through the soffit) far above the layer of insulation.  The air contained in the insulation remains stagnant which ...
