Nailbase Wall and Roof Panels

A cost-effective, energy-efficient Construction system that saves labor, time and cost.

USA SIPS nailbase panels are high quality foam core panels suitable for many residential and commercial building applications. They are one-piece components suitable for the walls and roofs of timber frame, post and beam, log and conventional structures. The panels are made of an Expanded Polystyrene (EPS) core bonded to APA rated Oriented Strand Board (OSB). An inner face of foil is available.

Exterior Skin
The oriented strand board skin on USA SIPS panels is exterior rated Exposure I by the American Plywood Association (APA). Exterior phenolic resin permits the panels to be used with normal construction delays.

Expanded Polystyrene Foam Core
The Expanded Polystyrene core has a density of one pound per cubic foot. Higher densities are available for special applications. You can choose from four standard nailbase panel thicknesses to meet the strength and energy-efficiency requirements of your application.

EPS is an inert, stable cellular plastic with superior insulating qualities. Unlike many other foam products, EPS is "Ozone-Friendly." No CFCs are used in the production of USA SIPS panels.

Other characteristics of EPS include:

Structural Integrity - EPS retains its shape indefinitely. It will not shrink, decompose or disintegrate due to age or weather.

Thermal Stability - The insulating value of EPS does not decrease with age.

Toxicity - EPS is formaldehyde-free.

Low Water Absorption - EPS has a closed cell structure. Its water absorption level is so low that moisture and the elements will not significantly affect its insulation values.

Permanence - EPS is an inert, organic material. It provides no nutritive value to plants, animals or micro-organisms. It will not rot and is highly resistant to mildew.

Energy Efficiency and Comfort
USA SIPS nailbase panels reduce cooling and heating costs even more than their R-rating would seem to indicate because they form a solid thermal envelope around the structure, uninterrupted by studs, sills or headers. This substantially reduces air infiltration compared with conventional construction techniques.
