Glue the rim joist, caulk the gaps, and overhang the wall sheathing to tighten this leaky building assembly
One of the leakiest parts of a house is where the floor meets the walls and foundation. On the Model Remodel project, Ben Bogie added air sealing to each step of the framing sequence, beginning with a sill seal gasket.
Step by step:
-
The mudsill and joists are added, but before installing the rim joist, he laid a bead of construction adhesive to bed it in. Adhesive is also applied up the edge, for an airtight corner.
- Huber’s new foaming subfloor adhesive was used to glue down the AdvanTech subflooring.
- Walls are framed as usual, but before adding sheathing, seal the gaps with silicone sealant.
- The wall panels are sealed to the foundation in perfect-world of animation-land, but the real foundation was out of square, so some onsite 'engineering' was needed.
- Last, he taped the corners and seams in ZIP System’s R Sheathing for a tightly seamed and well-insulated wall.
