How Insulation Works

The most important factor in reducing operating costs and saving energy in the extreme climate conditions is proper insulation. Installing insulation in the walls makes your home more comfortable by helping to maintain a uniform temperature throughout the house. Attic and basement wall insulation alone can reduce your energy bill by around 20% or more.

The amount of energy you conserve depends on a few factors: your local climate; the construction, size and shape of your house; the type and efficiency of the heating and cooling systems, the fuel you use and even the living habits of your family.Typically, installing insulation in the walls, professional contractors usedifferent materials including sprayed foam, cellulose, fiberglass, batting, bubble foil and foam board as every installation process is unique to each project.

Naturally, heat moves from a warmer to a cooler space. During cold seasons it flows directly wherever there is a difference in temperature: from heated living spaces to the outdoors and to unheated areas – basements, attics or garages. When it is warm, heat moves from outdoors to the house interior. To maintain comfort and uniform temperature inside we replace winter loss ofheat by using heating system and remove it in summer by air conditioners. Installing insulation in walls, ceilings and floors decreases the cooling or heating required by providing an effective resistance to heat flow.

Blankets, batts, low-density foams and loose fill limit air movement as the still air is an effective insulator that eliminates convection and has low conduction. Some foams, such as polyurethane, polyisocyanurate and extruded polystyrene, are filled with special gases providing additional resistance to heat flow.

Reflective insulation works by reducing the amount of energy that travels in the form of radiation,providing at least single reflective surface that creates the air gap between the closed inner environment and outer hot surface.Some forms of reflective insulation also divide a space up into small regions to reduce air movement, or convection, but not to the same extent as blankets, batts, foam and loose-fill.Such types of reflective insulations are generally made from pure aluminum foil supported through various backing materials such as hard foam, air bubble polyethylene film, plastic material or cardboard.

Except proper drywall, bathroom, basement types of insulation, there are many other things you can do to conserve energy in your home as well.
