Well designed and properly installed tilt-turn windows can provide you with energy savings of over 30% per year. We offer double and triple insulated glass with a choice of Argon or Krypton gas and with a low E coating. Our standard window has a U-value of 0.28Btu/hR2. That corresponds to an R value of 3.6 (1/U). Our passive house windows can have up to R 10 ratings. Currently the only US-based company, Henselstone provides the newest 90mm profiles with triple insulated passive house glazing in hardwood, metal-clad wood, and vinyl.

Thermal imaging proves it: the red areas show where heat is lost. The more red is shown, the higher the heat loss through the individual building components. To help prevent this, dual and triple seals are standard on all Henselstone windows and doors. We also use energy rated installation materials to guarantee ratings for complete openings.
