Midway Windows & Doors

The Envirosealed Replacement Vinyl Windows are tailored for home remodels. Alliance windows will provide your family with thermally efficient, maintenance free windows that are strong and insulated with our proprietary InnovativE® glass system. Our windows feature the latest technology in energy saving materials and construction. The wide selection of window styles is sure to provide you with the design you want and with the energy savings that will satisfy you.

Our product is engineered to increase energy efficiency so your windows will keep you comfortable whatever the weather. Our glass package incorporates our exclusive InnovativE® along with the high-tech Duralite® composite spacer system. Duralite® spacers can improve total window U-values by up to 0.04 and save 1,200 lbs. to 1,600 lbs. of CO2 production and significant energy costs per year in an average home. If every home in America had windows with InnovativE® and Duralite® warm edge technology, we could save the environment over 58 million tons of CO2 pollution.

Our replacement windows are built of the highest quality vinyl for a lifetime of trouble-free performance. The fusion-welded frames and sashes provide extra strength and durability while the insulated glass provides superior thermal performance. The triple Low E coated, argon gas-filled insulating glass system with warm edge spacer technology reduces your energy costs. Our high performing, high quality products give you a faster return on your investment than most other products. With an investment in high performance windows, your energy dollars get a maximum return and you are more comfortable financially as well as physically. Our planet benefits too from the low impact of materials and manufacturing.
