The combination of joining a horizontal head and sill extrusion with vertical jambs to provide an opening for moveable or secured sash. Methods of joining the frames include mechanical (screwed) or fusion welding of the extrusions. The mechanical method allows for easier repair and better operation.

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.

Sometimes referred to as glass housing or insert, consists of horizontal and vertical extrusions. Fusion welded sash frames create strength while adding a more aesthetically appealing look due to its continuous style.

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.

Lengths of vinyl and aluminum that are formed using architectural dies that have been precisely engineered to assure specified tolerances and thicknesses.

Refers to the upper horizontal boundary of the window and represents the top of the entire window.

The bottom horizontal member forming the frame of a window. The sill steps out from the building and should be stepped or sloped to provide the means for water and debris run off.

The left and right vertical members forming the sides of a window frame.

Horizontal and vertical extrusions assembled together for the purpose of holding the glass and allowing for opening and closing, as well as providing a view to the outside.  The sashes are housed inside the window frame.

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.

The addition of a reflective low emissivity layers of microscopically thin optically transparent layers can be applied in two ways; hard coat or soft coat. The later of the two has longer lasting and better thermal properties. Low-E non-metallic coatings can also be applied in different levels of thickness. Multiple coatings Low-E creates an optimum barrier from harmful ultraviolet rays and creating temperature controls.  As the method indicates it reflects hot and cold back to its source.

Material used to bond two or more pieces of glass together to prevent air and gas leakage and provide a low conductance seal. Spacer material that references “warm-edge” technology is far superior to the conventional method of using high conductance aluminum spacer bars. The fourth corner is hermetically sealed after insertion of gas filling.

Inert gas is used to fill the cavity created by joining two or more pieces of glass together. Gas being denser than air provides a better barrier to unwanted temperatures and sounds. Proprietary gas combinations are far superior and affordable in comparison to the low-end Argon gas or a high-end gas such as Krypton. Gas filling aides in limiting the radiant and conductive heat loss of long-wave room-side heat energy through the windows glass.

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.
