Installing Radiant Heating Panels Over Concrete
Installing Ecowarm RadiantBoard over concrete may be desired to create a more responsive slab assembly, cover an existing slab in a remodel, or deal with height considerations. There are three assemblies that we recommend that may meet you design objectives. We have included detailed cross-sections for installing radian panels over concrete with and without a vapor barrier.
Ecowarm RadiantBoard may be installed directly over concrete slabs only when the contractor has verified that moisture conditions will be adequately controlled by the use of a sealant on the slab or a vapor barrier under the slab.
Ecowarm RadiantBoard Over Plywood with Concrete with Vapor Barrier or Waterproofing
Radiant panels can be installed on 5/8” T&G treated plywood with a vapor barrier or waterproofing over concrete slabs only when the contractor has verified that moisture conditions will be adequately controlled by the use of a sealant on the slab or a vapor barrier over or under the slab.
The plywood may be either floated over the slab or attached with Tap Cons if the concrete floor has some irregularities. When using a sealant and adhesive on top of the slab, the sealant may be a combination sealant/ adhesive such as Sika Bond T-21 or a vapor membrane adhesive such as Hydroment Ultraseal.
Ecowarm RadiantBoard over plywood, foam insulation, and vapor barrier or waterproofing
An extra layer of high-density foam insulation is a good idea to reduce downward heat loss if height limitations permit.
Ecowarm RadiantBoard may be installed on 5/8” T&G treated plywood, over foam, and with a vapor barrier or waterproofing over concrete slabs only when the contractor has verified that moisture conditions will be adequately controlled by the use of a sealant on the slab or a vapor barrier over or under the slab.
