In the Standard Installation we have your old windows or doors removed and disposed of. The opening is then cleaned and adjusted to fit the new products. The product is then set in place and shimmed to hold it in and also so there is a solid point to fasten the windows to the frame. We then foam the gaps to create a proper seal around the window and to help keep heat in your home. The gaps on the inside are then covered with a casing of your choice. On the outside your product is either sealed with caulking against your bricks or siding or it is cladded with aluminum to give it a distinct accented look and cover any gaps.
