Door Threshold / September 17, 2018 / Martine Letourneau.
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. 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.
Many exterior door thresholds have bottom plates. These plates allow the door to seal but can be difficult barriers for scooters and wheelchairs. The tracks on sliding glass doors can be significantly damaged if a scooter runs over them. These are just a few example of the need for threshold ramps. They can help you overcome barriers and make getting around easy. These ramps are sold in a variety of shapes sizes and materials. They can be custom fit for your home or business. They are also designed to be non-skid and provide good traction. This prevents slips or slides.
With the rough opening clean and prepped for the new door and jamb move the system into place as one with door hung on hinges. Temporarily shim the side jambs tight top and bottom ends in the rough opening. Temporary shims at the bottom hinge may also be required to straighten door sag. The top hinge will sag just be aware that you will compensate for it later with shims and a screw to snug it when the door is installed permanently. Use of a level isnt necessary just align the jambs flush with the interior plaster and shift shims to square the door in the jambs with even spacing reveal.
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.
