Description

The 40 mm-thick GUTEX Thermowall window reveal panel is a wood fibre insulation product designed for use around window reveals and at critical points in external thermal insulation (ETI) systems. With a thermal resistance of R = 0.975 m².K/W, it complements Thermowall-L panels by minimising thermal bridges around openings. Packaged in sheets measuring 1200 x 400 mm, it is easy to handle and cut on site, ensuring a neat finish to window reveals before the application of the façade render.

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.

Our ITE expert’s opinion

This window reveal panel eliminates the need for the usual DIY method of cutting a scrap piece from a standard panel to fit around the window frames. The time saved and the continuity of insulation achieved more than justify its cost compared with a homemade cut-to-size solution.

Why choose the GUTEX Thermowall 40 mm window reveal panel?

Specifically sized for the Thermowall system’s window frames, this reveal panel ensures seamless continuity of insulation, unlike a hand-cut piece of standard EPS panel. The GUTEX Thermowall 40 mm reveal panel versus a standard EPS panel cut to size
Native system compatibility with Thermowall-L Requires cutting and adaptation
Total insulation continuity; same composition; risk of thermal bridging at the joint
Dedicated thickness of 40 mm, calibrated for the application; variable, to be adjusted on site
Installation time: Quick; longer (custom cutting)
