Window installation with exterior insulation is a challenge. Solve the problem with ThermalBuck.
ThermalBuck extends the mounting point for windows & doors, and insulates the rough opening to limit thermal bridging.
ThermalBuck outperforms a traditional wood buck, and protects the integrity of your window installation.

Most people would assume it makes zero sense to build a passive house in a hot climate. The indoor/outdoor temperate differences aren’t as extreme as they tend to be in other climate zones. But a passive house still offers a huge performance increase from traditional building methods, and a great… Read more
If a window isn’t installed properly, it won’t matter how energy efficient it is.
Installing windows on a building with exterior insulation isn’t easy. The window and the rigid foam or mineral wool need to line up on the same plane for good drainage, cladding attachment, and to prevent compression of the insulation. Rough openings are the weakest spot on a building for water intrusion, which can cause a great deal of damage, and lead to expensive repairs.
Traditionally a wood buck is built to extend the mounting point of the window to create a flush plane. But wood can rot, warp, and shrink over time, affecting the operation of the windows, and causing damage to the building envelope.
Wood has a low insulating value, which leads to thermal bridging around each window and door. Thermal bridging allows heat to transfer, which not only reduces the energy efficiency of the building, but it causes condensation to form, and more potential damage from moisture. It’s not easy to flash wood bucks, and be confident that you’ve got a good air & water seal.
ThermalBuck extends outward from the RO to create a flush plane with the exterior insulation and/or rainscreen. The unique “L” shape supports the weight of the window, and transfers loads to the structure.
ThermalBuck has an r-value of 4.4 per inch. Coated in a waterproof resin and installed with an air & water barrier sealant and nails, it eliminates the need for flexible flashing tape inside the RO.
4.0″ ThermalBuck, 3.5″ Roxul Comfortboard mineral wool, 3/4″ rainscreen. ThermalBuck integrates with the WRB for a tight building envelope.
*We recommend ThermalBuck installation with DAP Dynaflex 800 Modified Polymer Sealant or Dow Corning 758 Silicone Sealant
