Insulated Concrete Forms (ICF) continue to grow in popularity, not only due to an increased focus on green building construction, but because of stricter building codes relating to minimum required R-values. ICFs have stronger insulation properties, which reduce energy consumption and heating costs. As a result, Amvic, one of Canada’s leading ICF producers, has continued to push innovation to stay in step with market trends. Their new standard, 90-degree XL corners join the rest of the Amvic ICF line-up as the strongest ICF blocks in the industry, according to the Canadian Construction Materials Centre’s form capacity test. They also incorporate the Amvic FormLock™ interlocking system, ensuring a tight and secure interlock between the forms due to the one-inch deep grooves that virtually align themselves. There’s also a six-inch centre-cross tie spacing that provides greater strength without the need for gluing or taping.

The 90-degree XL corners incorporate many of the proven, patented innovations of the recently introduced Amvic Plus 3.30 Series. Available in both a six-inch and eight-inch concrete core size, the new XL corners are now eight square feet of surface area, with a 48” x 24” x 16’ size configuration. 

The 90 Degree XL corner incorporates two diagonal cross ties, one on either side, along with the radius-formed corner. These features virtually eliminate the chance of blowout while pouring concrete in the normally stressful corner area. The corner cross ties also incorporate two 8 ½” x 2” attachment areas every eight inches on centre for exterior siding and other exterior finishes. Additionally, if there is a requirement to use a half-block, the attachment strip is still incorporated in the half-block.
