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.
