Frequently Asked Questions

If the walls and ceiling of my home are well insulated, do I really need to insulate my basement?

FAQ - Insulation and Weatherization
The importance of basement insulation depends on whether the basement is heated. If you heat your basement, or if your furnace or other sources of heat are in the basement, you should insulate the basement walls to contain the heat. If not, you should insulate the basement ceiling to reduce heat loss to the basement and keep your floors warmer.

Do I need to insulate the floor in my basement?

Insta-Insulation
YES. The floor and walls are a significant source of heat loss. An insulated floor is warmer and drier; and it has direct influence on your comfort. Putting carpets on a floor only makes it feel warmer. If you have a heated floor insulation is very much necessary, as the heat loss through the floor would be higher than 50%. This heat loss is a huge and unnecessary waste of money. Return on investment for floor insulation is very quick, mainly because of the low cost of INSTA-PANELS®.

Is it better to insulate basement walls from the outside or from the inside?

Insta-Insulation
Both ways of insulating (inside and outside) have different advantages and disadvantages. We recommend insulating basement walls from the outside if possible. This method of insulating is more difficult to do but does save space inside the house. Insulating basement walls from the inside is very common as well though, and is generally a less expensive way to provide thermal protection.

Why should I insulate my home?

Thinksulation - FAQ
Insulation increases the overall comfort of a home and adds to its resale value. It keeps a home cool in the summer and warm in the winter because it resists the flow of heat. Heat is a form of energy and always seeks a cooler area. It flows out of the home in the winter and into the home in the summer. By reducing heat flow, a properly insulated home uses less energy for heating and cooling.
