Build nearly unlimited wall widths, 3 different insulation values, corners, angles, T-walls, columns, pilasters, brick ledges, and radius walls, using just a few standard components.

Panels made of Expanded Polystyrene (EPS) and Ties made of High Density Polyethylene (HDPE) create a Concrete Form that will accommodate vertical and horizontal Reinforcing Steel as required. Temporary bracing is usually required for vertical and horizontal alignment only.

Filling the cavity with concrete will create solid concrete walls with 2-4 hour Fire Resistance Ratings (FRR). The EPS Forming System will stay in place and turn into the best insulation available today, saving you energy costs for the lifetime of the building.

Five different wall widths are available (nominal concrete widths of 12" [300mm], 10" [250mm], 8" [200mm], 6" [150mm], and 4" [100mm]) and can be combined with the Quad-Lock Extender Tie to add 12" [305mm] to any standard cavity size.

Three insulation values are possible, giving you the choice of true R-Values of 22, 32, and 40 h*ft²*°F/BTU ; U-values of 0.28, 0.20, and 0.15 W/(m²*K).

The Quad-Lock System encompasses these components:

• Panels made of EPS, available in 2 thicknesses (2¼" [57mm] and 4¼" [108mm]) and with optional Fastening Strips
• Ties made of High Density Polyethylene (5 standard lengths plus Extender Ties and Brick Ledge Ties)
• Corner, Angle, Window, and Straight Brackets to eliminate bracing at corners and build bucks or end caps
• Metal Tracks & Wire Top Ties for starting and finishing the wall assembly

These components will allow you to assemble all concrete forming for your walls, including corners, arches, any angles, columns and pilasters, as well as T-Wall connections. Transport and storage costs of Quad-Lock are substantially lower compared to pre-assembled block systems.

Ordering and keeping track of inventory is easier (you would need at least 45 different parts to do the same with pre-assembled blocks). The Excel™-based Quad-Lock Estimating program makes it quick and easy to calculate all materials needed for your job and the cost.
