SilveRboard HD ( high density )- (10 sheets, 2ft x 4ft x 2in - R10) 80 sqft under slab insulation is a high performance , high compression strength (35psi) flat-sheet insulation material made from expanded polystyrene (EPS) which is bonded to a reflective film laminated on both sides. This highly effective combination of materials offers a high R-value per inch, exceptional board toughness and load capacity compared to traditional flat-sheet rigid foam insulation, as well as provides a built-in moisture and air barrier. This non perforated SilveRboard rigid foam insulation (EPS) offers builders a higher performance product which increases job-site efficiency and reduces labor costs. No off-gassing and does not contain fluorocarbons; exceptional long-term thermal resistance (LTTR); and increased thermal resistance in lower temperatures.
SilveRboard SB35 high density contains 10 sheets 2 in x 2 ft x 4 ft -80 sqft non structural rigid insulation board with a layer of reflective metalized polypropylene film on both sides which increases board strength and flexibility
Designed to be installed below-grade and under high- load concrete slab applications, as continuous insulation, a vapor barrier and reduce thermal bridging - ideal for under commercial slabs , driveways, sidewalks and foundation walls
Exceptional long-term thermal resistance in lower temperature - SilveRboard insulation installed below-grade outperforms XPS insulation: exhibiting better R- value retention and a lower moisture absorption over extended freeze-thaw cycles
Creates a thermal envelope for maximum heat/cooling efficiency, the non-perforated film functions as a vapor barrier when joints are taped with an approved vapor barrier tape
