Attic Insulation

A poorly insulated attic will lead to a gradual damage to your home, brought on by heat and moisture. A well insulated attic does not allow water vapor to seep in and erode the walls of your home.


If you’ve been receiving soaring energy bills it is time to take a look at your attic, more specifically the insulation.

Heat buildup in the attic can cause the swelling and cracking of the shingles on your roof. It may also soften the plywood on your deck.

Insulating the attic will address these woes before they happen.

Ice Dams

Ice dams equal heat loss which in turn equals high maintenance and utility bills. Ice dams cause water to leak down to the ceilings and walls below, eventually damaging your shingles. It also causes mold and mildew in the attic.

Frequently Asked Questions

What properties make spray foam insulation a better choice in the attic than fiberglass?

Though fiberglass is the traditional attic inclusion in the attic, it can never be a permanent solution to maintain the desired air conditioning inside because it will always have space for air to pass through. Spray foam insulation on the other hand seals even the tiniest cracks and gaps, thoroughly protecting the space from outside elements while maintaining proper conditioning of the attic space.

Is open-cell spray foam or closed-cell foam the better choice when it comes to attic insulation?

Although both open and closed cell foams are good and act as a barrier, open-cell foam is useful in dark areas like attics since it cannot be exposed to sun or water and can last forever if such conditions are met. Secondly using open-cell foams in attics allows homes to breathe better according to insulation experts.

Am I still required to ventilate the attic after insulating it with spray foam?

Not at all. The insulation is installed under the roof deck.  This elevates the plane of insulation from the ceiling to the roof deck, creating a conditioned space in the attic. After an insulation, temperature in the attic usually ranges between 80°-90° as against the normal temperature of 150°.

Does the spray foam insulation help keep a quieter and calmer home?

Yes. As the insulation seals the building well, it reduces the sounds of traffic or any kind of noise pollution drastically. In fact, it also helps keep bad odor from outside at bay. As compared to fiberglass, it has more density.

Which has a larger investment: spray foam insulation or traditional fiberglass insulation?

Spray foam insulation is no doubt expensive but having said that, the chances of your getting an RoI (Return on Investment) is well within 3-5 years as insulation saves costs on energy bills manifold. Spray foam insulation also lasts for a couple of decades.
