Door Threshold / September 12, 2018 / Carine Auclair.
Most entry door thresholds are manufactured from metal or a combination of metal and wood. Metal thresholds often have black anodized coatings that are easily scratched or dented. Wood thresholds can be stained scratched and dented as well. Some manufacturers have now manufactured plastic covers to protect their exact thresholds dimensions and include the covers with the complete door unit. There are other pre-molded protectors available from online suppliers of temporary protection products. There are also a variety of tapes that can be used for threshold protection.
During construction contractors will pass through the doorway with materials and equipment needed for the construction project. Each pass risks scratching or denting the home entryway. Temporary protection should be in place prior to the start of construction and should include protection for all the aspects of the entryway. Doors can be protected with temporary cardboard door protectors available from a variety of manufacturers. Several protectors are not only made from recycled cardboard but can be reused and recycled entirely again making these protectors truly green. The first protector to market and most popular is DoorGuard.
5. TOP HUNG OR BOTTOM ROLLING Some bifold doors are hung from the top to allow for a minimal threshold at floor level but with all the weight of the door being supported from the top a substantial upgrade of the lintel is normally required for strength and stability. Bottom rolling folding doors are a cost effective and popular alternative since the weight of the door is carried at ground level rather than suspended from the lintel. Whether you decide on an aluminium upvc or hardwood bifold door it is a major purchase for your project and one that should be carefully considered to ensure the very best value for your money.
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.
