Attic Insulation Photo Album: Making a Cape Cod Style Home More Comfortable

Homeowners in Ashburn, VA with a Cape Cod Style Home wanted to make their home more comfortable year round and save money on their energy bills. This home had several knee walls. Knee walls are commonly found in finished attic spaces, and provide support to rafters in timber roof construction projects. This additional structural support can come with a cost if not properly sealed. When an attic and knee wall are not properly insulated, outdoor air enters the home and leads to problems like ice dams, high heating and cooling costs, and increased allergens circulating throughout the home. After doing a thorough inspection, our sales professional recommended removing the old and in-efficient attic insulation and installing our SuperKneeWall Solution. Applying closed-cell spray foam along the roof deck, joists, windows, and soffit vents completely sealed-off outdoor air from entering the home. Now that it is air-tight with proper insulation, these homeowners have seen a drastic reduction in heating and cooling costs, have more protection against ice dam formation, and are experiencing healthier air quality.

Spray Foam Installation

We can insulate knee walls with different kinds of insulation but in this case, spray foam was chosen.

The quality of spray foam is hard to beat.

Spray foam insulation outperforms all other insulation materials in terms of R-value, resistance to mold and moisture damage, durability, air sealing, and versatility.

Closed cell spray foam creates an air and thermal barrier.

Closed-cell polyurethane spray foam is applied to the roof deck to create a continuous air and thermal barrier.

Air Sealing a Roof and Knee Walls

An average of 3" of closed cell spray foam is installed.

Not as easy as it looks.

Yes, a contractor is more expensive, but that extra cost comes with peace of mind that the job will be done correctly. Save yourself the headache, of wasted time and materials, and prevent damage to your home.
