Attic hatches are notoriously leaky and are often under insulated. The challenge here was to build a hatch with deep insulation (i.e. at least R-36) and has great air sealing details. Luckily my plans came with details to build a hatch to meet the specifications. You may recall that in a previous post ( https://flatrockpassivehouse.blogspot.ca/2017/08/the-attic-hatchway-landing-and-catwalk.html ) I illustrated that because of the depth of insulation in the attic, the hatchway had to be built with deep sides much like that of a deep window buck. Trying to push the hatch door straight upwards would just lead to the door binding so the back end of the hatchway was sloped to make getting into the attic and moving the hatchway door easier. To plan the build I had to think a little about how the hatch would tie into the air tight barrier. Initially, when the OSB on the ceiling was installed, 3M and acoustical sealant was used around the perimeter of the hatchway buck. This mad
This is a blog about building a more sustainable lifestyle in Newfoundland. We built the Flatrock Passive House in Flatrock, Newfoundland. As it stands, this is first performance house built to the PHIUS standard in Newfoundland. Construction is complete but the project is still moving forward. We are currently exploring and devising options that deal with food security. We recently completed a vegetable garden and root cellar and are currently working on a winter greenhouse!
