PEPI REFLEKT POLY 3mm is a reflective thermal insulation material consisting of polyethylene foam laminated on one side with a metallized PET film and a protective reflective layer.
This thermal insulation material is used under the concrete layer of heated floors, it must be laid the reflective side down. Material has an absolute vapor barrier.
|Under the concrete screed in water - heated floors
|LDPE foam + metallized PET foil on one side of foam layer
|Thermal conductivity (U)
|Thermal resistance (R)
|Infrared reflection ratio
*Valid in constructions with an air gap
