vinyl replacement window

Over 57 years of experience

In 1945 Duane H. Linford began building windows and other glass products in a small shed in the back of his grandfather's home in Salt Lake City, Utah. In the years following, Duane gradually acquired the help of his four brothers as Utah's demands for the Linford brother's top quality glass increased. The Linford Brothers were dedicated to hard work and exceptional customer service

Today the same values still guide the Linford Brothers Glass Co., now run by Duane's sons Paul, Ray and Mac. Linford Bros. Glass Co. now sits on over 8 acres and has developed over 150,000 square feet of window production and manufacturing facilities. Linford's production and its 200 Salt Lake employees have been great contributors to the Utah economy for over half a century. In 2003 Linford's won the Best of State award in the Merchandising: Glass: Plate and Window category.

Window Sizes: All window products manufactured by Linford Brothers Glass are manufactured 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.

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.
