Under Concrete Insulation For Radiant Heat

Radiant floor insulation under wood floors.

Under concrete insulation for radiant heat.

Simply imagine a warm mass of concrete or asphalt exposed to the elements and pouring btu s freely into the atmosphere and you ll understand what we mean. Radiant heat can be an electrical heating element embedded into a very thin concrete overlay then tiled carpeted or have wood flooring installed over it. Crete heat r 6 or r 10.

This radiant heating insulation can be used under most flooring material. A john siegenthaler a consulting engineer who specializes in hydronic heating system design responds. Quite simply concrete floor radiant heat is a system of pex tubes that carry hot water throughout a concrete floor or slab. Slabs that include embedded hydronic tubing for radiant heat always need a continuous layer of horizontal insulation under the entire slab.

The foil within the product acts to spread out the heat signature of the heating coils. Today s radiant heating systems water based or electric are built on the essential principle of heating the radiating material so it may warm the space above it. Ecofoil under slab insulation is superior to traditional outdated forms of concrete floor insulation such as polystyrene or foam sheets. The reflectix concrete slab insulation is an innovative easy to handle product that increases the energy efficiency of radiant floor and snow melt systems under concrete.

A continuous layer of horizontal insulation reduces heat loss in the winter and it reduces condensation of humid air on the slab during the summer. Rfoil ultra cbf r 3 8 and underpad r 1 1. Rfoil 2222 series reflective r 13 0. We stock rfoil and crete heat insulation brands for use in concrete slab and between the joists pex radiant heating installations.

Insulationstop is the best source for top quality products at the best price. Melting snow and ice with radiant heat consumes a staggering amount of energy. 0 2 inch 5mm closed cell polyethylene foam. Downward heat loss from a radiant slab should not exceed 10 percent of upward heat output a ratio derived from european installation standards for floor heating systems it s possible to calculate the r value needed to meet.

Radiant heating insulation plays a vital role in concrete radiant floor heating systems. The point is radiant floor company can accommodate any circuit arrangement for any slab zone. Rigid insulation concrete products like foam sheeting are easily broken and must be used with an extra vapor barrier plus standard foam or polystyrene concrete insulation does not stop radiant heat loss or gain. Q how much insulation is necessary under a typical radiant slab.
