GENERAL WINDOW INFORMATION

Window Sizes: All window products manufactured by Linford Brothers Glass are built to call out size. Example: A 4040 window measures 48" x 48" the Rough Opening should be ½" larger in width and 3/8" larger in height.

Installation: All vinyl window products are to be installed sitting directly on the sill. The windows should be installed level and square. Sealant should be applied to the nail fin prior to being attached to the exterior of the wall surface. The head fin cannot be nailed. Nailing the head of the window through the fin voids any and all warranty. If support or attachment of the window head is required, place a nail above the nail fin and bend it over into the fin, thus allowing the header to lower without compressing the window in the center. The header will bend down or straighten as other building materials are applied to the structure. Flash over perimeter of nail fin and caulk, in accordance with building codes and good construction practices.

Maintenance:
Glass: The glass can be cleaned with any cleaning product specifically designed and formulated for the cleaning of glass.
Frames: Vinyl products can be cleaned with a name brand product called Soft Scrub, this product also comes with a bleach additive. The product with bleach cleans the best, but be careful of fabrics and other materials that can be affected by bleach.
Lubrication: The frame should be cleaned periodically, especially the sill. A name brand product called Armor-All can be used to lubricate the frame. This product works exceptionally well in the lubrication of vinyl materials.

Visual Water: Any operating window, either horizontal slider or single hung (vertical sliding), will leak air and water. This leaking process is called air and water infiltration. This factor is part of the overall testing methods of all window products. Most, if not all, windows are tested using special processes so that the performance can be published. All Linford Brothers Glass window products are tested by independent testing facilities with the results available upon request. Water infiltration is more visible in a horizontal sliding window, due to one half of the window moving to one side or the other on top of a track. Windows are constructed with weep holes allowing any internal water to weep to the exterior of the home. Single Hung windows also allow water infiltration, however, the sliding section of the window covers the entire sill when closed thus covering any water that may infiltrate the window. Depending on weather conditions it is normal to see water in the sill section of window products. The snap-in replaceable track is cut so that approximately ¼" is left open at each end. This gap is the weep system for the water infiltration. The water will flow to the ends of the track and then drain out of weep holes on the exterior of the window.
