Southwall expects this acquisition to accelerate its automated production of Heat Mirror insulating glass, improving cost-competitiveness and broadening adoption of the energy-saving glass technology.

Heat Mirror insulating glass is a multi-cavity system that suspends one or more low-emissivity and solar-reflective Heat Mirror films inside of an insulating glass unit to create two, three or even four insulating cavities without adding weight.

Heat Mirror suspended film technology combines film-based and glass-based technologies with insulating performance ranging from R-6 to R-20 while minimizing solar heat gain and blocking UV radiation

Dennis Capovilla, CEO of Southwall, said: “We established the joint venture 24 months ago to directly address the challenge of manufacturing high performance Heat Mirror insulating glass at volume.

“As the market increasingly demands higher energy efficiency performance that can no longer be achieved with dual-pane insulating glass technology, this acquisition positions Southwall to drive broad market adoption of higher performing Heat Mirror suspended-film technology.”
