GUTEX Thermowall 40 mm window reveal panel – External wall insulation, R=0.975

The essential addition for window frames without thermal bridges

The 40 mm-thick GUTEX Thermowall window reveal panel is a wood fibre insulation product designed for use around window reveals in external thermal insulation composite (ETICS) systems. It complements the Thermowall-L panels installed on the main façade and ensures the continuity of the insulation at the specific points where openings are located. With a thermal resistance of 0.975 m².K/W, this 40 mm panel minimises heat loss around window and door frames – an area where thermal bridges are common when the reveal is not treated with suitable insulation. Its wood fibre composition, identical to that of Thermowall-L panels, ensures perfect compatibility with the rest of the system. Available in the 1200 x 400 mm format, it can be easily cut to the precise dimensions of each window frame, ensuring neat installation without wasting time on site. It is packaged in bundles, making it easy to transport and handle, even for the small quantities required to treat window reveals. This panel forms part of a comprehensive approach to addressing thermal bridges, which is essential for achieving the energy performance targets set for renovation or new-build projects. When used in conjunction with the Thermowall system’s connecting profiles and approved render, it guarantees a finish around openings that is both aesthetically pleasing and high-performing. Facade contractors and external thermal insulation contractors will find this window reveal panel to be a reliable solution that is consistent with the rest of the Thermowall system, ensuring that external thermal insulation projects are carried out to the highest standards, from the main wall right up to the window reveals.
