WrightRoof Natural² insulation panel system

25 04 144 Elements Encap Oakwrights Content Block

Natural, breathable roof system

WrightRoof Natural² is a high performance structural timber roof system designed to deliver excellent energy efficiency. By using thicker STEICOzell insulation, the system helps to lower the U-value and minimise cold bridging for a warmer, more efficient building, while also enhancing the envelope thermal mass.

Ideal for both residential and commercial projects, the system exceeds all current building regulations and is a smart choice for sustainable, modern construction.
