Outstanding test results
Viceroy's windows have earned the highest ratings for Air, Water and Wind Load. There are no higher ratings possible! What this means to you is exceptional air infiltration, water and wind resistance and extremely high energy-saving performance.
High Tech Glass - Particular 272 + i89 TM technology
Viceroy's double pane enhanced performance glass window features 2 Low- E2 coatings. They reflect escaping heat back into the room. Both coatings effectively act as a barrier to retain radiant heat within the home for a superior U-factor. As a result, a higher indoor humidity can be maintained, thereby creating a healthier, more comfortable living environment.
Our Argon-filled glazing technology adds further insulating value to the window. Combining our 272 + i89 TM glazing, and incorporating a stainless steel spacer with dual-seal construction you have today's most advanced insulglass available.
