Vitro Architectural Glass will sell LandGlass and VIG Technologies’ tempered vacuum insulating glass (VIG) products in North America.

Vitro reached an agreement to offer tempered VIG units in North America beginning in late 2021.

The company also plans to install LandVac equipment and begin manufacturing VIG units in its North American facilities as the market for VIG products develops.

The 8.3mm tempered VIG units consist of two fully tempered lites of glass separated by a non-leaded metal seal and a vacuum space.

The inclusion of fully tempered glass enables the LandVac VIG unit to be used globally across indoor and outdoor temperature extremes, which can cause failures in non-tempered VIG units.

VIG units deliver an R-value of 14, which is closer to the R-value of a traditional wall than glass. Improved R-values in cladding materials are in demand as building owners and developers face imperative incentives to minimise their environmental impact, from new stringent energy code updates to Net Zero energy goals.

“Building envelope materials with extraordinary R-values, such as VIG products, have the ability to reduce demand for artificial heating and cooling,” said Martin Bracamonte, vice president, marketing and innovation, Vitro Architectural Glass.

“That energy use reduction results in commensurate reductions in greenhouse gases. Vitro is proud to provide this new product platform as yet another way to maximize the environmental value of our products.”

VIG units can be used alone as a replacement for monolithic glass or as a substitute for the interior lite in a traditional one-inch insulating glass unit (IGU) where it forms a secondary airspace and creates a hybrid IGU that significantly improves the unit’s thermal efficiency, delivers better noise abatement and eliminates condensation.
