Door Threshold / September 14, 2018 / Laure Lacharite.
Theres something about thinking and working in three planes that appeals to me. Making customers happy and feeling comfortable in their home environment makes me happy too. Nothing can compare to the satisfaction of knowing a job has been well done seeing and feeling a beautiful and properly installed door operate smoothly. In modern homebuilding techniques most housing built here in the Salt Lake City area after the mid-1960s is 2x4 or 2x6 wood stick frame construction with an exterior veneer of brick stucco or some type of lap siding. Prior to that time many if not most homes around here were built using four inch wide cinderblock (4"x8"x16") masonry walls with a brick exterior veneer. Thermal efficiency properties of new door systems have improved greatly over what was available forty or fifty years ago.
Currently the best tape on the market T-X268 is a specialty tape that combines UV chemicals in both the tape and adhesive so it wont break down with ultra violet light. There are additional tapes available for sill protection as well including those made with blue polyvinylchloride. The cost to protecting doors jambs and thresholds are well worth the small investment. The average cost for a cardboard door protector one cardboard jamb protector and tape for the threshold is less than 25.00 The cost to replace just a door alone can range from several hundred dollars to several thousand dollars.
4. THRESHOLDS Although a flush threshold is the most popular option especially for internal bifold doors this may not always be practical in some cases and a conventional raised threshold will need to be used. It is important to note that the height of these can vary considerably with some upvc bifold door thresholds exceeding 125mm. Such a high step-over threshold may create an accessibility issue for children and the older generation. The latest bifold door designs offer raised thresholds designed to minimise the trip hazard with some offering thresholds as low as 50mm high.
Several sill manufacturers provide plastic threshold protection that is specific to the model of sill they are selling. Unfortunately heavy duty plastic protectors are not available for every type of entry threshold so the protection is not easy to obtain. There is one surface protection company on the west coast that does inventory plastic threshold protection for two of the most common sill profiles. For protecting sliding door tracks there are two types of threshold protection. The first is a hinged plastic protection that flips over the tracks of sliding doors to keep them clean from debris.
