Insulation
Insulation is a critical part of your radiant heating installation.
What is Reflectix® Insulation?
Reflectix® is a 5/16" thick, seven layer, reflective insulation which is available in rolls of various widths and lengths. Two outer layers of aluminum foil reflect 97% of radiant heat. Each layer of foil is bonded to a tough layer of polyethylene for strength. Two inner layers of insulating bubble pack resist conductive heat flow while a center layer of polyethylene gives Reflectix® high reliability and strength.

Reflectix® reflects the sun's rays in the hot summer months. It also retains interior heat and helps to eliminate potentially damaging ice dams during the winter months.
Radiant heat, the major source of heat flow, is energy in the form of infrared waves. It travels at the speed of light, even through a vacuum, and is either transmitted through, absorbed into, or reflected by any material it contacts. Air, water and glass, for example, transmit visible light in varying degrees. A white surface, such as snow, reflects it; and a black surface absorbs it. Reflectix® Insulation reflects up to 97% of the radiant energy striking its surface.
Reflectix® Insulation reflects up to 97% of the radiant energy striking its surface.
Installing heat without insulation underneath is not a good idea; the price of the insulation is usually saved in energy cost in one season
Floor heat loss: 25% of your heat loss is downwards, so if you insulate under your slab or floor, you could save 25 % of your heating cost.
Remember opposites attract.
Warm air is attacted to cold and vice versa.
Think about heat for a second ... heat does not rise
Using a foil faced insulation will reflect the radiant heat back to where you need it most, within your home. Placing reflective insulation under the floor allows you to put the heat where you want it, allowing you to save money.
