Spray Foam Insulation Photo Album: Full Attic and Crawl Space Job - Windsor

This home in Windsor, ON needed a variety of work in the dirt crawl space as well as in the attic. We started by removing the debris out of the crawl space. Old poly, garbage and more. We installed our CleanSpace barrier on the dirt floor, and sealed it to the foundation walls with our closed-cell spray foam insulation. We then sprayed the insulation with DC315 Paint which is a thermal/ignition barrier. In the attic, we removed all the old, ruined insulation in the joists. We spray the mould on the roof deck with our Mold-X2 product, a two-part system of botanical and stain remover. New baffle vents were then installed. The ceiling joists had no air barrier, the only way to retroactively achieve this without ripping down the plaster/drywall and stapling a poly barrier to the underside of the joists, is to spray foam the ceiling from inside the attic. This also seals up all wire and pipe penetrations! The last step is to blow in new cellulose insulation. This was a beautiful before & and after transformation!

Before

You can see the ceiling joists have pink fiberglass insulation- not ideal. The roof deck has mould all over the wood. This is actually very common to see!

Before

More of all the things we don't want to see in our attic.

Before- Crawl Space

There is a poly barrier over the dirt, which has mostly turned to dust! Poly is not meant to sit on dirt- it will rip, breakdown and render itself useless very quickly.

After - Crawl Space

We've installed our CleanSpace barrier with drainage matting over the dirt floor. Our spray foam team have sealed the CleanSpace to the foundation wall, and applied DC315 (thermal/ignition barrier) to the foam. The far wall is only partially sprayed because it is not an exterior walls, but we still need to create that airtight seal between the wall and the CleanSpace

No More Mould!

Wow. Our Mold-X2 product has removed all the mould off the roof deck (what the shingles are on). The lumber looks brand new.

Mid-Way

We've spray foamed the ceiling joists, per the explanation in the album description. The final step is to install new cellulose (blown-in) insulation.
