Expanded Polystyrene (EPS) Roof Insulation

Roof and Wall insulation

Expanded Polystyrene (EPS) is one of the leading materials used for roofing insulation in commercial buildings with flat roofs. It is typically used combining flat panels to establish the required R-Value, and tapered panels to channel the flow of water towards roof drains or scuppers. It can also be used in conjunction with other insulation materials, just to create the tapers, with the other flat materials creating the R-Value.

EPS is also used to retrofit existing commercial buildings with additional insulation. Due to its light weight and rigidity, EPS panels can easily be installed between trusses in an existing roof. Pieces can be pre-cut at the factory to accommodate the spacing of the trusses.

The panels are also used in residential construction with both gable and hip roofs. When a cathedral ceiling is required, EPS panels can be placed between the exposed tongue and groove finished ceiling and the OSB or plywood roof creating a well insulated and tight roof. This application is typically found in contemporary home and log home construction.

Extruded Polystyrene Wall Insulation

STYROFOAM Brand Foam Block Insulation

We also supply STYROFOAM Brand DECKMATE & ROOFMATE Insulation Extruded Polystyrene used for commercial and residential roofing insulation applications. There are several STYROFOAM Brand Foam roof insulation products for specialized roofing applications:

STYROFOAM™ DECKMATE™ - a Type X extruded polystyrene product designed for use in conventional low-slope roof applications. It can be installed directly on structural steel decks beneath a sheet membrane or a standing seam metal roof, eliminating the need for a thermal barrier such as gypsum board.

STYROFOAM™ DECKMATE™ Plus - a Type IV extruded polystyrene product designed for use on conventional roofs beneath mechanically fastened, fully adhered or ballasted sheet membranes. It can be used on built-up, modified bituminous and metal roofs, and installed directly on a steel deck without the use of a thermal barrier such as gypsum board.

STYROFOAM™ DECKMATE™ Plus FA - designed for use in fully adhered conventional low-slope roof applications. The Type IV extruded polystyrene insulation boards can be installed directly on structural steel decks beneath a non-bituminous sheet membrane, eliminating the need for a thermal barrier. DECKMATE Plus FA is available in flat and tapered board stock.

STYROFOAM™ ROOFMATE™ - with 1/2" x 1/4" drainage channels on the bottom long edge, it's designed for installation above waterproofing or roofing membranes in protected membrane roof (PMR) applications. This Type VI extruded polystyrene insulation helps keep the membrane at a more steady temperature, minimizing the effects of weathering, freeze-thaw cycles and damage during and after construction.

STYROFOAM™ Ribbed ROOFMATE™ - has corrugated ribs on the top of the insulation and 1/2" x 1/4" drainage channels on the bottom long edge of each board. The Type VI extruded polystyrene board is designed for installation above waterproofing or roofing membranes in protected membrane roof (PMR) applications that use pavers or patio stones as ballast. Pavers can be installed directly over the ribbed foam surface without the need for pedestals.
