Product Dimensions 

ThermalBuck is available in 8 foot lengths, with 7 different size depths to choose from. The width of the portion that extends past the rough opening to the exterior of the structure, is matched to the thickness of the exterior insulation and/or rainscreen, and available in seven sizes:  1.0″, 1.5″, 2.0″, 2.5″, 3.0″, 3.5″, and 4.0″.  

The tongue, or portion that lays right inside of the rough opening, is always 2 1/2″ in length. For all widths of ThermalBuck, the thickness of the tongue is consistently 1/2″.  

The integrated sill pan features a 1/16″ slope from a depth of 1 3/4″ from the exterior edge on the tongue. The jamb pieces of ThermalBuck act as an end dam.  The back dam is created when the interior is sealed.

Continuous Insulation & Rainscreen 

To determine which size of ThermalBuck is best for your installation, consider the combined depth of the continuous insulation & rainscreen. If they don’t match up exactly and you’re between two sizes of ThermalBuck, in most cases we recommend choosing the smaller of the two sizes. 

Always consult the manufacturers’ recommendations for the building materials used in the entire wall assembly, and the architect or builder specifications.

Continuous Insulation 

Taking into consideration the climate conditions, building design, insulation type and cladding, some wall assembly designs don’t add a rainscreen. In this instance, choose the depth of ThermalBuck to match your exterior insulation depth.

Consider the manufacturer’s recommendations for the building materials used in the entire wall assembly, and the architect or builder specifications.
