We removed all the old fiberglass insulation. Why? It's not the correct insulation type, for a variety of reasons. Blown-in cellulose is the appropriate application. Along with that, the pipe and wire penetrations that come into the attic are not air-tight. We need to access all of these point to ensure heat loss is at a minimum! This insulation is also full of mouse droppings (mice love pink fiberglass).
Once the removal, air sealing and new baffles are completed, the new blown-in cellulose can be installed. 
Beautiful work here by our crew for this London homeowner.

Porblem: Cracks coming off windows in poured foundations are a headache. Most solutions harden over time, crack and then fail as the foundation goes through freeze/thaw cycles. 

Solution: Our solution stays flexible to move with the foundation. it allows the water to be controlled.

However, in areas where the insulation won't be covered by drywall or another barrier, such as unfinished basement or garage walls, an additional layer of protection is needed. That’s where our thermal and ignition barrier coating comes in.

This specialized coating is applied directly over the spray foam to meet safety requirements and protect the insulation from fire hazards. Whether you need spray foam insulation in an unfinished basement or crawl space, our team can ensure that it meets all safety codes with the application of this thermal and ignition barrier.
