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. Traditionally a wood buck is built to extend the mounting point, but wood can rot, warp, and shrink over time. It’s not easy to flash wood bucks, and be confident that you’ve got a good air & water seal to prevent moisture intrusion. Wood also has a low insulating value, and allows thermal bridging around the rough openings, reducing the impact of the exterior insulation.
ThermalBuck solves the challenge of installing nail flange windows & doors with exterior insulation by extending the mounting point to create a flush plane for cladding – but it also insulates the rough opening, limiting thermal bridging around windows & doors. Coated with a waterproof resin and secured to the rough opening with an air & water barrier sealant* and nails, it’s simple to install and easier to flash than a wood buck. ThermalBuck saves both time and money when installing nail flange windows with continuous insulation – with more performance.
The continuous insulation solution for the high-performance building envelope.
*We recommend ThermalBuck installation with DAP Dynaflex 800 Modified Polymer Sealant or Dow Corning 758 Silicone Sealant

ThermalBuck Goes Rogue with Matt Risinger
Matt Risinger is a well-known talent in the building industry. Not only for his fine craftsmanship as high-end home-builder Risinger Homes, but also as a building science expert and educator.
Based in Austin, Texas, Matt appears at building events and trade shows across the U.S., and creates easy-to-follow, real-world content from his construction sites (that’s a lot of fun to watch) for his avid followers on social media.
Matt recently featured hosted a demo in Austin, “Hands-On Building Science: Window Installation with Exterior Insulation” featuring ThermalBuck on Risinger Goes Rogue, as a smart, simple solution to the challenges builders face when installing windows with continuous insulation.
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.
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.
