Quad-Lock ICF Panels

Regular Quad-Lock Panels are 48" [1218mm] long, 12" [305mm] high, and 2¼" [57mm] thick with interlocks along the top and bottom of the panels.

Quad-Lock Fastening Strip (FS) Panels have the same dimensions as the Regular Panels, but feature 1½" [38mm] wide plastic fastening strips, molded into the panels every 12" [305mm]. They provide a continuous anchoring point for exterior cladding/lapped siding (e.g. vinyl or fiber-cement siding) where needed.

Quad-Lock PLUS Panels have been developed for walls requiring higher insulation values. Dimensions for Plus panels are the same as regular panels except for the thickness of 4¼" [108mm].

Quad-Lock PLUS-FS Panels have the same dimensions as the Plus Panels, but feature 1½" [38mm] wide plastic fastening strips, molded into the panels every 12" [305mm].

The Fastenings Strips are located 2" [51mm] to the left of all deep grooves in FS Panels (i.e. every 12" [305mm]) and extend to the panel's surface in small spots for easy identification. Plastic ties are locked into the fastening strips to create an uninterrupted vertical fastening surface 1½" [38mm] wide (no breaks or gaps to complicate siding installation). The FS Panel can be used on one side or on both sides of the wall as needed.

The above panels contain molded slots every 2" [51mm] to interlock panels with Quad-Lock Ties, ensuring every panel will align with precision. Panels are lightly scored every 2" [51mm] to make measuring and cutting easy. Every 12" [305mm] panels have a heavier groove to mark the placement of the ties.

Quad-Lock Extra Panels can be added in one or more layers behind the exterior panel layer of any standard Quad-Lock ICF wall during construction.

Using combinations of Quad-Lock Panels, many different insulation values are possible, giving you the choice of true R-Values of 22, 30, 38, 45, 53, 61 and more (h*ft²*°F/BTU). Details...

All Quad-Lock panels are molded of fire retardant Expanded Polystyrene (EPS). EPS is a foamed insulation that has a zero ozone depletion rating. EPS does not, and never did, contain CFCs or HCFCs. The Quad-Lock Panel is inert and chemically stable and will not emit any gases into homes or commercial buildings. In fact, EPS is considered to be world class insulation with qualities that make it impervious to time and moisture.

Example: You want to build an R-53 TMO wall with an 8" [200mm] concrete cavity: Based on this table, you will need QPX2 (2" Panels) on both sides, two QPEXTRA (Extra Panels), FTB4 (4" Black Ties) and XT (Extender Ties).
Notes: TMO = Thermal Mass Optimized ; Disclaimer: Thickness of EPS foam on the building's interior should not exceed 4". Some configurations / insulation thicknesses may not be approved by local building codes / officials without an engineer's approval - see Guide to Code Compliance.
