Rigid Foam Insulation (EPS): SilveRboard
SilveRboard Rigid Foam Insulation is a high performance flat-sheet insulation material made from Expanded Polystyrene (EPS) which is coated with a layer reflective lamination on both sides. This highly effective combination of materials offers a higher r-value per inch compared to traditional flat-sheet insulation as well as provides built-in moisture and air barriers which eliminate the need for house wrap.
SilveRboard Rigid Foam Insulation (EPS) offers builders a higher performance product which increases jobsite efficiency and reduces labor costs.

SilveRboard Rigid Foam Insulation (EPS) is acceptable for floor, wall and roof insulation for above and below grade and can be used for the following concealed applications:
- Exterior/Interior Above Grade Walls
- Exterior/Interior Below Grade Walls
- Re-siding Projects
- Slab on Grades
- Exterior Roof Decks
- Cathedral Ceilings
- Cavity Walls
- Radiant Floor Heating
- Snow Melts
SilveRboard XS has been specifically engineered for exterior wall sheathing application on wood or steel frame construction. The reflective laminated surfaces of SilveRboard XS are micro perforated in order that the SilveRboard XS exterior wall sheathing insulation materials can “breath”. SBXS will allow an average water vapor permeance of 217
ng/Pa.s.m2 or 3.48 Perms and an air permeance (system leakage) of 0.047 L/x./m2 at 75 Pa. SilveRboard XS physical characteristics (see chart below) are within the nationally accepted guidelines for air and vapor permeance, making it unnecessary for further application of a house wrap. SilveRboard XS is a high performing, high quality and economical material for exterior wall sheathing installations.
Reduces sounds transmission through interior walls.
