A new insulation and framing system combining the benefits of both standard wood-stud, fiberglass batt insulated construction and high-efficiency Structural Insulated Panels (SIP’s) is now available to architects and home-builders in the U.S.

The INSUL-WALL® rigid EPS (expanded polystyrene) insulation panels are also an Insulated Framing Form (IFF) system allowing framers and builders to construct perfectly square super pre-insulated wall sections up to 8 feet wide right on the jobsite in less than 5 minutes. INSUL-WALL® is a hybrid integrating familiar stick-framing practices and offering 25%-40% material cost savings over standard stressed-skin SIP panels.

INSUL-WALL®’s patented IFF SIP panel system increases crew productivity because it combines four processes into one—simultaneous stick-framing and insulating plus a built-in 2 inch thick thermal break, while completely eliminating the need to install exterior sheathing, saving time and materials on the jobsite.

Architects, home-builders, and framers benefit from INSUL-WALL® panels which create state-of-the-art insulated walls using off-the-shelf 2x4 and 2x6 pre-cut length lumber and familiar carpenter’s details. No special tools, design methods, or field re-training is needed. The precisely cut slots in the solid EPS insulation panels act as permanent framing jigs to place each wood framing member, speeding erection and delivering walls that are plumb and true every time. Designed superior to standard SIP’s, the interior side of Insul-Wall® panels are open for easy electrical and plumbing installations as well as inspections, with easy-access 3” x 3” horizontal channels at strategic heights for receptacles and switches. These engineered efficiencies translate into shorter build times, lower labor costs, plumb/true framing for better interior finishing, and lower waste.

The INSUL-WALL® system offers multiple “green” advantages with its superior insulating properties, up to 2 times that of fibreglass batts with the same R-value rating.

INSUL-WALL® panels have a built-in 2” thermal break, eliminating thermal bridging by isolating the framing, thereby reducing energy consumption for home heating and cooling—by far the largest portion of home energy use. Over the life of a home, homeowners can expect to save on energy bills and enjoy a higher resale value. The standard available R-values are R-20, R-24 and R-28.

Compared to fiberglass batts, INSUL-WALL®’s EPS insulation is resistant to mold and mildew, keeping its “R” value even when wet, yet is “breathable”, won’t rot, doesn’t “age”, and is dimensionally stable (no crushing, slumping or sagging), so its effectiveness is permanent. It is also chemically stable (does not give off methane), and does not give off CFC’s or HCFC’s, which is important to homeowners who are concerned about indoor air quality. EPS is easily recycled the world over.

INSUL-WALL® panels are lighter in weight, yet offer the same energy-efficiency, wall strength and durability advantages of SIP construction at substantially lower cost. Engineering tests show that SIP construction is several times stronger than conventional wall framing. SIP’s offer greater resistance to wind shear and racking, and are increasingly the material of choice for walls and roofs in hurricane and earthquake-prone areas.

The ease of building with the INSUL-WALL® system makes it ideal for both professional builders and do-it-yourselfers, and very appealing for home-building projects in rural areas; mountains, lakes-side properties, farms, and even hard-to-access islands. Homebuilders can order just the wall panels needed for their project, or chose from 21 standard design shell-framing packages available complete with pre-fabricated roof and floor systems, or order custom configurations. INSUL-WALL® provides product complete documentation and ordering assistance.

Green-R-Panel Systems Inc. is the licensed manufacturer of INSUL-WALL® throughout Canada and the U.S. The patented building technology combines traditional stud-framing methods with high-performance rigid foam insulation allowing both professional builders and do-it-yourselfers to build BETTER…FASTER…GREENER. Headquartered in the Greater Toronto area, the company was founded in 2008 by Richard Lewin, a building industry veteran with over 20 years experience in prefabricated building components and systems. In 2012, INSUL-WALL® launched the Green Home Building Solutions blog as a resource for practical, cost-effective solutions for sustainable home building news and information.
