ThermalBuck extends the mounting point for windows & doors, and insulates the rough opening to limit thermal bridging. 

How it works

Window installation with exterior insulation is a challenge. Solve the problem with ThermalBuck.

Installation Steps

ThermalBuck outperforms a traditional wood buck, and saves time on your window installation. 

ThermalBuck vs. wood

If a window isn’t installed properly, it won’t matter how energy efficient it is.

 

High performance wall assemblies are becoming more common as builders work to make homes more energy-efficient, and meet energy code requirements. But builders know attaching windows with rigid foam or mineral wool isn’t easy.


ThermalBuck solves the challenge by extending the mounting point for windows & doors to create a flush plane for cladding, and allows structural attachment of the window.


Simple to install and easier to flash than a wood buck, ThermalBuck saves both time and money.

The continuous insulation solution for the high-performance building envelope.

Simplify Window Installation

ThermalBuck solves multiple problems when using exterior insulation and/or rainscreens. It extends the mounting point of windows & doors to create a flush plane for cladding attachment. In addition, it allows for structural attachment to prevent the compression of insulation and preserve a tight wall assembly. 

ROUGH OPENING MEASUREMENTS:
Consult the window manufacturers’ recommendations, then add an additional 1/2″ on all 4 sides to accommodate ThermalBuck.  (see installation for example)

Improve Performance and Efficiency

ThermalBuck simply does more than a wood window buck. It insulates the mounting points of windows & doors, and simplifies flashing. Dimensionally stable and strong, it helps to maintain the integrity of the window installation. ThermalBuck is part of a continuous insulation solution, and an essential part of the efficient building envelope. 

R-values range from 4.4 to 17.6. View the results of our thermal testing and see how ThermalBuck outperforms wood 2:1.  

Build Green and Live Green

Using ThermalBuck to improve your window installation means you’ll use fewer natural resources to heat and cool your home year-round. Not only will that save you money, it’s better for the environment too.  

ThermalBuck reduces thermal bridging and prevents moisture from accumulating, which improves your indoor air quality – and that benefits your family’s health.
