Why choose eps Rigid Solutions ?

Thermal Performance

EPS has great long-term R-value value retention which gives design professionals and building owners consistent performance over the lifespan of the building. In addition, its R-value increases as temperature decreases which is especially useful in cold climates.

Healthy Environment

Thermal Performance

EPS is manufactured with just steam and water and does not contain any CFCs or HCFCs. It does not off-gas and does not promote growth of mold and mildew. When installed contributes to improved indoor air quality.

Construction Versatility

EPS physical properties such as low weight, rigidity and formability allow it to be used in a wide range of building insulation applications ranging from highly complex molds to simple rigid board panels.

Sustainability

Construction Versatility

EPS is one of the most economical insulation materials to manufacture using less energy and natural resources and one of the highest performing and cost effective insulating materials on the market. EPS foam waste can be recycled reducing landfill waste.

SilveRboard® Graphite

Graphite Polystyrene Insulation

High performing and cost effective non-structural graphite polystyrene (GPS) rigid insulation board for exterior wall applications on wood or steel frame construction. The expanded polystyrene (EPS) core is embedded with graphite particles which increase the thermal performance, compared to conventional EPS.

In addition to the increased thermal resistance, the foam is laminated with a reflective film on both sides increasing board strength and flexibility, reducing site damage and waste. The reflective laminated surfaces are micro perforated giving the panel high water vapor permeance greatly reducing the likelihood of trapped moisture through the increased drying potential. The larger panels and laminated film help improve job site efficiency and reduce labor costs.

Envirosheet: EPS Insulation Board

Envirosheet EPS Insulation

Envirosheet is an economical rigid insulation board made from Expanded Polystyrene (EPS) offering a high R-value per dollar when compared to other generic rigid insulation solutions on the market. It is a highly flexible and cost-effective product that can be used for above grade and below grade interior applications in residential or commercial construction.

Envirosheet EPS insulation can be installed on most substrates and can accommodate virtually any finish ranging from stucco, siding and masonry veneer providing professionals great design flexibility. The EPS has high permeance to allow the passage of water vapor, reducing the risk of trapped moisture in the wall assembly.

Envirostrap: Rigid Foam Insulation

Envirostrap Rigid foam Insulation

Envirostrap is a rigid insulation board made from closed cell Expanded Polystyrene (EPS) with two integrated furring strips on one side. This highly effective combination of materials offers a 2-in-1 solution incorporating insulation and finish attachment surfaces that can be used for both above grade and below grade interior applications. The furring strips can either be fully recessed inside the foam for interior finish installation or can protrude from the surface of the foam by ¾” (19mm), creating an air gap that is needed for exterior cladding installation.

The two furring strips are located 16” on center (406mm) on each panel and are 2.5” (63mm) wide and make for an easy installation of finishes such as siding or gypsum board (drywall). The combination of the thicker strips (1” (25mm)) with the spacing and width provides the user with the widest range of warranty compliance by the various siding manufacturers.
