Why WebLok™?

Quality
WebLok walls make incredibly strong structures. Each one-piece WebLok stacks level and locks firmly with adjacent blocks, making it easy to build level and plumb walls with strong, tight joints.

Concrete curing strength is at least 50% greater than standard, removable forms, and stronger than other ICFs. The cavity of a WebLok wall creates an uninterrupted, solid grid of concrete. This unique concrete web is structurally superior to a solid cement wall of similar width. Not just because concrete cured inside the WebLok cavity cures harder, but because the patented web shape is engineered to create optimal structural strength.

WebLok ICFs insulate better than comparable alternatives. Around the concrete grid, they form an uninterrupted, interlocking, wall of superior insulation and a vapor barrier with an effective R-26 insulation value. As a frame of reference, conventional walls require R-50 to achieve similar energy efficiency. And unlike ICFs that use connectors to join their inner and outer surfaces, WebLok ICFs use no conducting devices that encourage thermal bridging.

A solid, concrete grid surrounded by EPS also provides an enhanced sound barrier. WebLok walls achieve a Sound Transmission Class Rating of 49. Tight-fitting, interlocking WebLoks leave no air spaces to allow air infiltration. No uncomfortable drafts, hot and cold spots, or temperature fluctuations. With properly filtered ventilation, only controlled, filtered air comes inside. Indoor air remains free of airborne pollen, mold, mildew, dust, and harmful allergens.
