Insulated Concrete Forms for Walls

Build unlimited wall widths with many different insulation values, corners, angles, T-walls, columns, pilasters, 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 accommodates vertical and horizontal Reinforcing Steel as required.

Filling the cavity with concrete creates solid, reinforced concrete walls with 2-4 hour Fire Resistance Ratings (FRR), low maintenance, and outstanding durability. The EPS Forming System stays in place to provide space to run small utilities, serve as backing for finishes, and incorporate superior, continuous insulation layers. The high insulation values, low air infiltration, and high thermal mass can achieve significant energy savings for building owners, operators, and tenants over the building's longer lifetime.

Temporary bracing is usually required only for vertical and horizontal alignment.

Many different wall and insulation thicknesses are available using ties and panels of varying sizes. The Quad-Lock System encompasses these components:

  • EPS Panels are available in 3 thicknesses, 4¼" [108mm], 3.125" [79mm], and 2¼" [57mm], giving you the choice of true R-Values of 22, 28, 30, 38, 43, 45, 53, and 59 [metric U-values of 0.28, 0.20, 0.15 and lower].
  • HDPE Ties are available in six standard lengths: Brown 18" [450mm] total nominal wall width, Red 16" [400mm], Green 14" [350mm], Yellow 12" [300mm], Blue 10" [250mm], and Black 8" [200mm] and they can be combined with the Orange Extender Tie to add another 12" [305mm] wall width.
  • Corner, Angle, Window, and Straight Brackets eliminate bracing at corners and allow building EPS bucks or end caps.
  • Metal Tracks & Wire Top Ties for starting and finishing the wall assembly
These components allow assembly of all concrete forming for your walls, including corners, arches, angles, columns, 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).
