Attic Insulation



Attics are probably the first place that homeowners should consider when looking to upgrade the insulation in their home.

Heat tends to rise and a properly insulated attic will help to retain as much heat as possible. It is not uncommon to have homeowners say that they have never looked in their attic or that it has been years since they did.

Having us look at your attic is a quick and easy way to check for potential problems with your roof, pests, ventilation, bed, and bathroom fan performance and venting, skylights, air or water leakage, and the state of your insulation.

An inspection by our professionals will provide information on much more than just your insulation.

Attic Ventilation

It is very important that attics are well ventilated to avoid damage from moisture, mildew or odors. Soffit and roof vents are critical components of a roof system and when insulating, precautions should be taken to preserve the flow of air from the soffit, above the insulation, to the roof vents which is possible only through ATTIC INSULATION.

We will inform you about your existing ventilation situation and what they can do to either preserve it or improve it.

Draft Proofing

The ceiling below your attic is full of holes, gaps, and penetrations. Warm moist air escapes through cracks, gaps, and holes in your ceiling into your attic. When this moist air meets the cold air in your attic it can condense which can lead to significant moisture issues such as mold, mildew, and rot.

While a properly insulated attic will help to slow down your heat loss, further actions can be taken to minimize the movement of warm moist air into your attic. Sealing air leaks is one of the more inexpensive home improvement activities you can undertake and yet it yields some of the highest paybacks in terms of time and money spent.

We offer draft proofing services with every attic installations. 

Energy auditors have identified draft proofing as “one of the best bangs for your buck when insulating your home.” 

Why Ice Dams Form On Your Roof?

Ice damming is a direct result of “differential” melting and freezing. When snow accumulates on the roof, it tends to melt in the upper areas where the temperature is warmer. The melting snow flows down to the lower areas of the roof, and begins to refreeze due to the colder temperature.

With Ottawa Insulations, sealing the attic and roof cavity is the key to preventing ice dams. The idea is to create a complete “system” where attic and roof are properly sealed, insulated, and ventilated.
