Door Threshold / September 17, 2018 / Martine Letourneau.
The front entryway including the door jambs and threshold is the focal point of your clients home. It sets the tone and expectation for the rest of the home and it can add or detract curb appeal. Entryways have been important dating as far back to the Greeks. According to Jesse Nevins of Coastal Carolina University "To ancient Greeks doors were considered sacred and surrounded with superstition. So much so that doors and the comprising parts had their own deities. For the Greeks a door was not simply a way to enter a building but a holy place itself worthy of the highest respect." Keeping doors jambs and thresholds looking great while a home is under construction or remodeling is important and is now easier than ever.
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.
They are known to flake and chip when exposed to sunlight and are often cited for creating more work than the protection provided. These low quality 2 or 3 mil. tapes often leave a sticky adhesive residue on thresholds as the adhesive used in the tapes softens in warm temperatures. Another option is to use fitted threshold protection made from molded plastic. The molded plastic threshold protectors are designed to protect the most common types of thresholds in residential or commercial construction. They are the most durable type of threshold protection and can be used for multiple projects.
Then re-assemble door system and re-shim into the indexed positions in the rough opening. At last now fasten jambs to the cinderblock with the masonry screws using shims at each screw location. Fine tune screw adjustments by wedging the shims to get the reveals around the door even. Adjust top and bottom jamb shims as necessary. Open and close door to check touching the weather stripping evenly top to bottom for any possible jambs twist. Some slight remaining jambs twist can be adjusted by persuading the jambs with a block and a hammer. Be careful. Now nail the shims permanently in position with a pneumatic nail gun shooting squarely into the cinderblock. Dont worry the nails should sink into the cinderblock as long as they are the proper length and are nailed squarely and firmly.
