Engineered Structural Wall and Roof System

A strong one-piece structural system, R-Control Panel provides superior insulation in exterior walls, ceilings and roof. Pre-engineered from lumber facings and solid EPS insulation, they create a monolithic structure with the strength of a continuous column.

A thick core of rigid EPS expanded polystyrene insulation is adhesively welded between stranded lumber facings to form a structural panel that will not twist, warp or be subject to racking.

The panel's structural grade adhesive has tremendous strength. It is not affected by moisture or temperature and has proven durability. The R-Control Panel has passed structural and fire tests as prescribed by national building code authorities.

Fire Performance Tests

• UBC 17-5 Room Corner Burn Test
• ASTM E 119 20-Minute with 3-Story Load Applied
• ASTM E 119 One-Hour, 3-Story Load with Hose Stream
• ASTM E 84, Surface Burning

Treated to Stop Insects*

R-Control Panels are treated with Tim-Bor to resist insects. Tim-Bor has proven itself in more than 20 years of application in Australia. Tested by AFM in the U.S., Tim-Bor is a safe treatment, not harmful to humans or animals and is EPA registered.

Solid Core Walls Stop Common Energy Leaks

• R-Value is stable for the life of the structure.
• Moisture commonly present does not affect the R-Value.
• No voids or cavities in exterior walls mean no energy-robbing air movement, thermal syphoning or convection looping.
• Wind washing of exterior walls that causes fibrous insulation to give up energy.
• Thermal short circuits including wood studs, nails, voids in batt insulation and joints.

Controlled Factory Construction

Pressure laminating is done under carefully controlled conditions, QC tests are made on a regular basis to insure consistent quality. Panels are factory assembled to exact specifications for use in home styles from traditional to contemporary.

Build With More Control

A panel package is delivered to the job site. The panels fit on standard lumber sill plates which are set in place on the floor slab or framed subfloor, Within hours the house shell is closed in and ready for interior framing, plumbing, heating, cooling, and drywall. Roofing and siding materials are conventionally applied to the exterior face.

Framing is used around windows and doors, at top and bottom plates, and panel corner connections. This provides continuous support, strength, easy nailing and snug fit.

R-Control Panel is the proven building method that gives you better control. Design Control, Material Control, Construction Time Control, Energy Control, Cost Control.

Panels are available in 4 x 8 foot sizes or complete wall sections. Standard panel thicknesses are 4 1/2", R-14; 6 1/2", R-22; 8 1/4", R-30 and 10 1/4", R-38. Ceiling and roof panels can be made to 12 1/4", R-44.
