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, flexible, and 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 (when installed with approved sealants). No need for flexible flashing tape when you use ThermalBuck – the coating is waterproof, and the rough opening is sealed when installed with DAP Dynaflex 800 Modified Polymer Sealant. 2″ galvanized roofing nails 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 the transitions of ThermalBuck and the WRB.
ThermalBuck insulates with an R-value range of 4.4 – 17.6.
