WINDOW BASICSWhen considering the purchase of replacement windows the following features
will assist you in understanding what a window should be comprised of. Replacement
windows are a major home investment and you should buy quality features that
will guarantee you a product that will not only continue to look good but will
perform for a lifetime. Dual Window Frame - When two or more materials, such as vinyl and aluminum are in concert together to provide the best in beauty and strength. The aluminum should be thermally broken or poured and debridged. This method deters the transfer of heat or cold to the opposite side. Combining vinyl and aluminum as the frame and sub frame creates a window that can house triple insulating glass without restrictions or hazards in operation. It also provides a superior anchoring material that virtually eliminates the joining and hardware screws from stripping out.
Dual Sash Frame – An additional material is inserted into the horizontal sash members for the purpose of stability and screw retention of hardware and locks. A revolutionary polystearate material increases the thermal properties of the location where the top and bottom sash meet or interlock, while providing the strength and durability that aluminum has. Extrusions – Lengths of vinyl
and aluminum that are formed using architectural dies that have been precisely
engineered to assure specified tolerances and thicknesses. Insulated Float Glass – Glass is processed via a method of floating on molten metal while the top surface is formed with gravity. This produces the finest optical quality in glass and is superior to conventional plate glass. The formation of two or more pieces hermetically sealed creates insulating glass. The larger the depth of multiple pieces of sealed glass is indicative to its thermal properties. Three pieces of glass creates two equal, 1” overall, air spaces and a center barrier.
8. Glazing - The act or process of securing glass within the sash. Interior snap-in glazing allows for the glass to be replaced easily if broken. It also means the glass cannot be removed from the exterior. Operational Window Parts
9. Balance System - The mechanisms used to allow smooth and
effortless operation of the sash up and down. Block and tackle
balance systems can be individualized based on the size and weight of the sash.
No matter what the weight of the sash is, it should be able to be operated
with one hand. Aesthetic Parts
22. Grids - Combination of vertical and horizontal bars that
cross to provide the appearance of small glass panes. Also referred to as a
muntin bar or grille. Internal grids permit easy cleaning of glass. Grids can
have rectangular, diamond or circular patterns.
