The High-Performance Building Envelope
For years architects and builders have struggled to solve multiple problems with window installation, particularly when coupled with rigid exterior insulation and/or rainscreens. Rough openings are the weakest spot for potential water and moisture damage in any building.
ThermalBuck solves a number of common issues that wooden bucks and rigid insulation introduce, and simplifies the installation of windows & doors. It improves the water & air seal at the rough opening, and insulates the mounting points of windows & doors.
Dimensionally stable, it won’t warp, shrink, or expand like a wooden buck. Lightweight and extremely strong, it is easy to install with one person.
Extends the Mounting Point
ThermalBuck extends the mounting point of windows & doors to meet the exterior insulation plane and/or rainscreen, and creates a flush plane for exterior cladding.
ThermalBuck is available in 7 different depths: 1.0″, 1.5″, 2.0″, 2.5″, 3.0″, 3.5″, 4.0″
Insulates & Prevents Moisture
ThermalBuck insulates the mounting points, and acts as a water & air barrier. No need for flexible flashing tape when you use ThermalBuck. Your rough opening is sealed when installed with DAP Dynaflex 800 Modified Polymer Sealant, and 2″ galvanized roofing nails that go through the 1/2″ tongue, penetrating a min of 1-1/4″ into the structure.
Flashing tape is used at the nail flange, and at the transitions of ThermalBuck and the WRB.
ThermalBuck insulates with an R-value range of 4.4 – 17.6
Elastic & Dimensionally Stable
ThermalBuck is dimensionally stable, unlike wood. It won’t warp, shrink, or expand like a wooden buck. Incredibly strong, durable and lightweight, it also offers integrated termite protection.
ThermalBuck helps maintain the integrity of the building envelope, and the operating ease of windows and doors.
Structural Attachment for Windows & Doors
ThermalBuck allows for structural attachment of windows & doors. Screws for the nail flange must penetrate through ThermalBuck a minimum of 1-1/4″ into the structure. With a compressive strength of 52 psi, it can handle hurricane force winds with minimal permanent compression. Shear strength is 70 lbs. per linear inch.
Architects and builders know all too well – if windows and doors aren’t mounted properly, it won’t matter how energy efficient they are.
