Quad-Lock 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 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 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-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].

Using combinations of Quad-Lock Panels, three different insulation values are possible, giving you the choice of true R-Values of 22, 32, and 40 (h*ft²*°F/BTU).

The panels contain molded slots every 2" [51mm] to interlock panels with the 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.

All Quad-Lock panels are molded of fire retardant Expanded Polystyrene (EPS) to a density of roughly 1.9lb/cuft [30g/l] for the regular-thickness panels and 1.5lb/cuft [23g/l] for Quad-Lock Plus Panels. The Panels' EPS Board Type Classifications are as follows: Regular Panels are Type IX in US and Type III in Canada, and Plus Panels are Type II in Canada and US. 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.

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.

Plus-FS (Fastening Strip) Panels

Building Tips:

Use Quad-Lock Plus Panels for:

  1. Additional Insulation (usually on exterior of building),
  2. Wall Width Transitions (e.g. from 8" to 6" concrete thickness, or
  3. A “belly band” (a raised horizontal relief detail between stories) for stucco application in multi-story applications.

Use Quad-Lock FS Panels for attaching:

  1. Lapped Siding or other finish requiring a continuous fastening surface, or
  2. Base Boards or Crown Molding using one row of FS Panels at the bottom or top of a wall, or
  3. Soffit - Place a row of FS Panels even with the soffit elevation; Snap a line where the soffit joins the wall; Glue and screw a horizontal 2x4 backer on the FS Panels to support the soffit material where it intersects the wall.
