ThermalBuck solves the challenge of installing windows and doors with exterior insulation by extending the mounting point to create a flush plane for cladding. Unlike a traditional wood buck, it insulates the rough opening, limiting the thermal bridging around windows and doors.

Thermal Buck insulates the rough opening with an R-Value range of 4.4 - 17.6 and creates a flush plane with exterior insulation. Coated with a waterproof resin and secured to the rough opening with an air & water barrier sealant and nails, it is a true continuous insulation solution.
Dimensionally stable and strong, it will not warp, rot, or shrink, and helps to support the weight of the window. ThermalBuck vastly outperforms a traditional wood buck by limiting thermal bridging, preventing moisture and creating an additional air and water barrier.
If a window is not installed properly, it will not matter how energy efficient it is. Thermal Buck is faster and easier to install than wood bucks, saving significant time, reducing labor costs and ultimately protecting the integrity of your window & door installation.
