Hi R+Plus glass systems detect and block radiant heat – keeping it in your home
during the winter, and out of your home during the summer.
It features a 7/8" single-surface multilayer vacuum-deposition Low-E insulated
glass unit filled with argon gas. The inert argon gas is about 40% denser than
air* to resist the transfer of heat. The result is a system that increases
energy efficiency – it’s over twice as efficient as ordinary insulating glass –
and decreases utility expenses.
