When you make an investment in new windows or doors, you want to be sure you receive expert, professional installation for an exact fit with no hassles. That’s why Intermountain Glass employs certified Installation Masters™ to ensure quality craftsmanship at your home.
InstallationMasters™ is a nationwide training and certification program, prompted by the Building Environment and Thermal Envelope Council (BETEC) through the U.S. Department of Energy (DOE) and developed by the American Architectural Manufacturers Association (AAMA). This program provides specialized training to new construction and replacement installers of windows and exterior glass doors. It is designed to teach installers the best practices and installation techniques based on established industry standards. An Installation Masters certification provides homeowners assurance that an installer participated in rigorous training and passed a written test.
Choosing a company to do any type of renovation on your home is an important decision. To aid you in you evaluation of potential window companies, we describe the four basic installation methods below. Each has its advantages and limitations. This knowledge will empower you to evaluate potential companies, and recognize those who cut corners.
Retrofit and New Construction
The installer removes the old window and cuts the siding back approximately 1 – 1/2″ around the frame. This allows the factory flange, which flashes the window and helps to keep it watertight, to be left on the window during the installation process (just like in new construction). The flange aligns the window on the framing to ensure it is properly supported. The window is then trimmed, sealed and caulked. This is the best method for installing windows in wood siding.
Win-Pac, Quick-Kit, or Tilt-Pack
Installers use this method in situations where the original window frame should be left intact, for example, an old wood double hung window in a brick home. New windows install in much the same fashion as the sash portions of the original windows. They sit securely inside the existing wood frames. This method may be preferred for historical or aesthetic reasons. There is no fin on windows installed in this manner. However, the existing frame supports the new window and ensures a weather tight fit.
Riding the Frame
This method is used in situations where removing the existing frame could cause damage to the siding. An example would be aluminum or steel framed windows in concrete or brick. In this method, the existing frame is left in place and only the glass and cross members are removed. The new window is custom sized to an exact fit and “rides” over the existing frame. A factory attached finishing trim provides protection from the outside elements. This method looks great when properly done but does reduce your daylight opening.
Collapse Out (No Nail Fin Application)
This method is typically used with aluminum windows and requires special tools to remove the existing frame without disturbing siding. After removing only the glass and cross members, the aluminum frame is collapsed out using a slide hammer or frame puller. Then, the frame is pulled from the stud framing and siding with little or no damage to the opening. The new custom sized window, without a nail flange, is fit within the existing opening and fastened through the window frame. Caulking is applied to the exterior between the new window frame and the siding and to the interior at the sill, jamb and headliner. This installation will require frequent maintenance to insure the window frame remains sealed against the elements.
