Your poured concrete basement walls are buried in the cool earth and are perpetually cold - about 17°F cooler than we like the interior of our homes to be. In the winter, the part of the foundation that sticks up above the ground is much colder than that. Heat moves from more to less. The dense concrete has a lot of mass and heat from our basement constantly flows into and through the wall by conduction. You can never heat them up. If you have a furnace, boiler, or water heater in the basement, the heat that comes off this equipment is wasted - lost into the cold concrete, instead of warming the basement and floors above it. In the summer, warm humid air from outside hits your cold basement walls and condensation forms, supporting mold. Results - cold basement, cold floors above the basement, higher fuel bills, more difficult to heat the house.
Solution
Foam insulation board is installed on your basement walls with Dr. Energy Saver's proprietary Foam-site fasteners. But not just any foam - Polyisocyanurate foam has the flame retardant properties to satisfy building codes to leave it exposed in a basement - unlike expanded or extruded polystyrene foam (EPS, XPS). In addition, the "polyiso" board has a foil facing to reflect heat so the insulation isn't doing all the work by itself. Results - warmer, more comfortable basement, warmer floors above basement, less condensation in the summertime, lower fuel bills, house is easier to heat.
