"I would rate them ‘A’s on everything. They were great. I would recommend them to family and friends. That actually was our second time using them."

"This past Winter was really unusual for us – too cold! Thanks to our triple-pane windows from Ameritech we have saved about 50% on our energy bill."

"The siding installation was well organized by the project manager and job site manager. The installers were professional and efficient! The siding looks amazing. I truly got a new house at the same address. I’m so happy."

"We had them out a couple of years ago and they replaced most of our upstairs windows. They did a wonderful job demoing the quality and value of their triple pane windows and gave us a good price."

"The technician who came to see us was punctual, knowledgeable and courteous and did a fine job of explaining and selling his product. Ameritech has always been very good about follow-up on our windows, even sending someone out to reacquaint me with the tilt-in cleaning or replacing the balance systems. We will most certainly use them again in the future."

Structural Integrity

Our window frames are vinyl and reinforced withHigh Density Reinforcement (HDR). HDR is a composite material that has structural advantages, similar to aluminum, without the sacrifice of thermal performance that occurs with the highly conductive metal. The thermal performance numbers are identical to wood while having a superior density number for enhanced strength. The result is the perfect combination of strength and screw retention in a thermally superior product. HDR will prevent your windows from bowing or warping especially during the hot summer months.

The double hung and slider achieve a DP-50 and beyond in the Structural Performance Test. Most all vinyl windows could not reach beyond a DP-35, (the higher the better) so HDR in conjunction with our improved window design greatly improves the structural performance.

HDR meets and exceeds AAMA 303 profile requirements. AAMA 303 is the standard that establishes the minimum requirement for dimensional stability, screw withdrawal, thermal cycling, weather ability, heat resistance and buildup and lead content for rigid composites used in windows.

DP Rating = 50
Air Infiltration = .08 [.30 is Passing]
Water Resistance = 7.52 [Highest Ever]
