Unicel Architectural Achieves 45-minute Fire Rating for Steel Trim Kits in Door Applications

Rating builds on Unicel Architectural’s award-winning fire rated Vision Control® and ViuLite® products for health-care, educational and other facilities

LONGUEUIL, CANADA, FEBRUARY 23, 2021 – Unicel Architectural Corp., manufacturer of Vision Control®, timber and aluminum curtain walls and skylight solutions, announces its Vision Control® and ViuLite® privacy and shading solutions have achieved a 45-minute fire resistance rating, including the hose-stream test, using its newly developed steel trim kits in door applications from global safety certification company UL LLC.

The products meet UL fire-resistance rated assemblies standards through the Unicel Architectural-manufactured steel trim kits that are combined with Pilkington Pyrostop® fire-rated glazing. These are offered with any of the company’s family of Vision Control®, Vision Control Mini®, and ViuLite® products and are UL-listed in the US and Canada.

The rating further extends Unicel Architectural’s award-winning fire safety ratings of 20, 45, 60 and 90 minutes for doors, windows, transoms and sidelights, which have been available for almost a decade. Unicel Architectural’s new fire-rated door trim combines with fire-rated Vision Control®, Vision Control Mini®, and ViuLite® units to form a fully fire-resistant door application.

“Our industry-leading fire safety capabilities were already well-known among architects, builders and glaziers,” said Samuel Doyon-Bissonnette, majority shareholder and head of engineering at Unicel Architectural. “Achieving a 45-minute UL fire resistance rating in door applications, to go along with our strong glass fire ratings, takes things to the next level. Using fire-rated products like Vision Control and ViuLite in building construction helps save lives and property at health care and other facilities”.

Pilkington Pyrostop® combines a physically robust fire protection shield with the high quality typical of regular glazing. In a fire, Pilkington Pyrostop® turns opaque, providing a strong barrier to flames and hot gases as well as effective insulation from intense heat.

Vision Control® and Vision Control Mini® are insulating glass units with integrated cord-free louvers providing maximum and maintenance-free control of vision, heat, light and sound. They combine louvers within glass that can be customized to virtually any shape for interior and exterior glazing applications. ViuLite® is a system of blinds that are permanently sealed within a double-glazed cavity for a completely dust-free and maintenance-free environment.
