Door Threshold / September 14, 2018 / Laure Lacharite.
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. 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.
This calculation is based on the specification of the double glazing together with the profile design and dimensions to determine the insulation benefits of the door measured in U-values with the lower the value the better the insulation achieved. The minimum acceptable under current building regulations for replacement doors is a 1.8 U-value but some local authorities will insist on lower values particularly for new build extensions. 2. GLASS SIGHT LINES Another important consideration should be the sight line or width of door profiles between each panel of the folding sliding door as this will affect the visible glass area available when the door is in the closed position. Most bifold doors are designed with dedicated profiles to minimise these sightlines as much as possible but some timber and many upvc folding doors use wide chunky profiles that produce very broad sight lines in excess of 200mm wide that will ultimately spoil your view.
I believe installation direct to masonry is the height of challenge for an entry door where skills and patience for a carpenter are truly tested. You really only have one chance to get it right - screw hole mistakes in the cinderblock dont allow for incremental jambs adjustments. Here is where carpentry meets art you must think and be creative. So the satisfaction of a properly installed door in this case becomes at least for me a real thrill. On the initial site visit to measure up the door youre going to tap on the walls to see if they are drywall or plaster.
