Attic insulation

Open-cell spray foam insulation’s unique texture - a property of its tiny, interconnected bubbles - provides an insulation value between R-3.5 and R-4 per inch. A open-cell spray foam R-value means that your home will experience improved temperature consistency after spray foam has been installed, reducing the cost of heating and even cooling your home.

In addition to insulating, open-cell spray foam insulation also seals cracks and crevices that allow the passage of air through your home. This makes it especially valuable in attic encapsulation where high temperatures in the summer force hot air through gaps around light fixtures, joints, and air ducts. That hot air doesn’t just affect your comfort, it also distributes dust, mold, and other allergens from the attic throughout the rest of your home.


Because open-cell spray foam has a spongy consistency, it allows moisture to pass through it. That quality and its lower cost make open-cell superior to closed cell for attic encapsulation and wall insulation, where it can be sprayed between rafters or studs. If your attic or a wall develops a leak, water will pass through the insulation, alerting you to the problem. This ensures water doesn’t sit beneath your roof, creating rot.

Why Install Spray Foam Insulation?

Air moves in and out of a home through every hole, crack, and crevice. Roughly one-third of air infiltrates through walls, ceilings and floors. Adding an advanced insulation system is necessary to achieve optimal building performance. Spray Foam is that advanced insulation system.

Spray foam insulation can maximize a homeowner's investment by sealing the building envelope to stop conditioned indoor air from escaping and prevent unconditioned air from entering a home.

Air exchange in and out of a home is a leading cause of escalated energy bills. The mechanical systems that heat and cool buildings are continuously operating; reducing extreme temperature variations saves on the overuse of mechanical systems and leads to lower energy bills.
