U need improved thermal performance. Vitro has options.
When it comes to thermal performance, U won’t believe how many choices Vitro Architectural Glass offers to improve U-values. Thanks to advances in low-emissivity (low-e) technology, architects have more options than ever to lower U-values and improve R-values wherever increased thermal performance is needed. In fact, with Solarban® double-silver, triple-silver and even quad-silver solar control, low-e coatings from Vitro available for use in double and triple pane insulating glass units (IGUs), improved R- and U-values are easier than ever to achieve.
Now, new Vitro products, like Sungate ThermL™ low-e coating and VacuMax™ Vacuum Insulating Glass (VIG) allow for even better R- and U-values than ever before.
Sungate ThermL™ U-Value Enhancing Low-e Glass
Specifically engineered for use on the interior surface of an IGU, Sungate ThermL™ low-e coating is designed to retain indoor temperatures by slowing down heat transfer through the IGU while allowing for a high rate of visible light transmittance (VLT). This results in up to a 21% improvement in the U-value over using a single solar control low-e glass alone.
VacuMax™ Vacuum Insulating Glass
With VacuMax™ Vacuum Insulating Glass (VIG), thermal performance more than triples. VacuMax™ VIG combines vacuum technology with Solarban® 70 low-e glass in an IGU that is just 8.3mm thick to provide exceptional thermal performance that rivals the performance of traditional walls. The unit’s slim construction and light weight allows it to be incorporated into virtually any traditional glazing system, window frame or curtainwall application. With R-values up to R20, VacuMax™ VIG units can deliver thermal performance that is 5 times better than conventional insulating glass and up to 20 times better than monolithic glass.
