Do you have difficulty keeping your home cool in summer and warm in winter? This is not surprising when you see how much air can escape a home. In some cases it can be like keeping a window open 24 hours a day all year long!
Simply topping up your traditional insulation won’t seal those gaps and cracks or deliver better energy savings. This is because r-value does not control air leakage. Traditional insulation, like fiberglass, can be further compromised by gaps and seams where air can get in and out.
What is R-Value
R-value is a numeric value given to insulation materials based on their resistance to heat. R-value does not consider air movement through or around the material once it’s installed in your home.
Consider this: a wool sweater on a cold fall day is warm and welcome. Wool has a high R-Value. But it doesn’t help keep you warm if the wind is blowing and flowing right through.
A windbreaker will be more effective in keeping you warm.
XCELUS spray foam insulation protects against air leakage because it forms an effective air barrier.

XCELUS spray foam is an insulation and air sealing system that works to help ensure that your home doesn’t suffer from air loss, while providing an effective R-Value. By expanding up to 100 times its original size, XCELUS seals cracks and gaps in attics, walls, ceilings and other spaces, where air might escape.
The amount of insulation you need depends mainly on the climate you live in. Your energy savings from insulation will depend upon the climate, the type and size of your house, the amount of insulation already in your house, and your energy use patterns and family size. If you buy too much insulation, it will cost you more than what you’ll save on your heating and cooling bills. Using spray foam helps ensure you have the right amount of insulation for your needs.
To get the marked R-value, it is essential that insulation be installed properly. This can help to reduce your heating and cooling bills. XCELUS sprayed in foam insulation is able to provide a high, code-compliant R-Value, while also air sealing your home. You’ll be maximizing your comfort while minimizing your heating and cooling bills.
