Best insulation for radiant floor heating.

Radiant heat insulation is installed to prevent heat loss from a pex radiant floor heating system most commonly pex embedded in concrete slab or stapled underneath the plywood subfloor. When installing your in floor heating you may want to install a layer of radiant floor insulation. Prodex total under concrete insulation is ideal for concrete slabs radiant floors and driveways. The insulation phase is crucial for a radiant floor.

The best way to control heat loss from radiant floor heating systems is to install thermal insulation below the electric heating cables or the hydronic heating pipes. This slab insulation is 0 2 inch 5mm closed cell polyethylene foam covered on one side with reinforced foil facing. Use radiant floor insulation. Mainly heated slabs radiate outward rather than downward so insulation on the edges of the slab is most important.

Slabs that include embedded hydronic tubing for radiant heat always need a continuous layer of horizontal insulation under the entire slab. Prodex exhibits less than 9 compression in thickness when subjected to loads associated with standard concrete floor systems. Need insulation for under concrete slabs slabs with radiant heat. The compacted aggregate base is first followed by a 6 mil polyethylene vapor barrier then insulation then rebar or wire mesh or both.

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. This way most of the heat is then directed towards the room greatly increasing energy efficiency. The best bang buck is usually a combination of rigid foam trapped to the foundation with a fiber insulated studwall. Ecofoil radiant floor insulation also called under floor insulation has become very popular in new home and commercial building applications.

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. Different insulation types help to minimize heat loss from convection air circulation conduction direct contact or radiation energy waves modes of. This insulation is placed below the hot water tubing or electric.
