About SilveRboard Graphite Rigid Foam Insulation

High performing and cost effective non-structural 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.

SilveRboard Graphite: Carbon Graphite Insulation

SilveRboard Graphite XS can be used as the second plane of protection under exterior cladding when the joints are properly taped and sealed, eliminating the need for an additional membrane. The laminated film comes micro perforated by default (denoted by XS) but is also available without perforations by special order.

How it Works?

Graphite Properties

Graphite is the most stable form of carbon. It is naturally occurring and chemically inert. When embedded in the polymer matrix it acts as a reflector of radiant energy giving the material its distinct gray color and improved thermal performance.

Heat Transfer Mechanism

Conventional insulation products focus on minimizing only two of three heat transfer mechanisms, convection and conduction. Graphite EPS minimizes all three of heat transfer mechanism, including radiation.

Reflective Properties

The embedded graphite particles serve as a coating on the walls of each cell causing radiant energy to be reflected many times as it moves through the insulation. The reflected energy has to travel through twists and turns, which takes more time than going in a more linear path.

Manufacturing Benefits

Not only does graphite EPS saves on energy once installed in a building but also during manufacturing. Graphite EPS can be manufactured with lower steam pressure which results in reduced energy usage due to lower cycle times. In addition, it has excellent dimensional stability and better fusion increasing manufacturing efficiency.

Why Use SilveRboard Graphite?

Superior Thermal Insulator

Superior Thermal Insulator

SilveRboard Graphite has a high R-value and an exceptional long-term R-value retention. It also provides increased thermal resistance in lower temperatures.

Built-In Water & Vapor Barriers

Built-In Water & Vapor Barriers

When joints are taped and sealed, it can function as a vapor barrier or a water shedding surface.
