Pittsburgh, Pennsylvania – Covestro has introduced the PUReWall range of prefabricated insulated structural wall panels. They are designed to eliminate common wall assembly components, and provide a cost-effective alternative to site-built framing.
The panels are constructed using conventional wood frames and polyurethane-based insulation. The rigid polyiso board continuous insulation reduces thermal bridging, and has an integrated weather-resistive barrier that eliminates the need for plastic house wrap.
When combined with a structural closed-cell spray polyurethane foam, the company claims the rigid polyiso board provides a similar unit shear capacity to continuously sheathed wood structural panels.
Other advantages include an increased R-value and decreased air infiltration, which contributes to a higher Home Energy Rating System index score. The panels are available in a range of configurations to meet the thermal requirements of different climates.
‘The system offers numerous benefits for panelisers, builders and homeowners,’ said Jim Lambach, Covestro’s manager of building and construction industrial marketing for polyurethanes. ‘By licensing our PUReWall technology, panelisers are able to integrate higher levels of functionality and quality in a wall assembly that simplifies on-site construction for builders with less waste, time and cost.’
