Door Threshold / September 16, 2018 / Marphisa Duffet.
Ive learned by the hard way of experience that its necessary to remove old existing jambs carefully. If directly fastened to masonry with cut nails jambs removal may break out the cinderblock unless the jambs are cut into short manageable lengths. An out of level concrete threshold step can be ground flat by a concrete cutting subcontractor or the door threshold can be adjusted by unscrewing and repositioning in the jamb by the amount out of level. Any attached brickmold and casing must be removed from the jambs to make installation easier with shimming. Also brickmold will probably have to be ripped in width to fit the overall brick opening width and height.
3. SECURITY Most folding doors will feature a high security locking system but many still use face fixed or flag hinges that can pose a possible security issue and allow the hinges to be removed from the outside when the door is closed. Some upvc bifold doors may also use an exposed gearing system that is accessible from the outside of the door when the door is closed which can also pose a possible security threat. You can eliminate these potential security problems by ensuring you choose a folding door that has fully concealed gearing and hinge fixings.
UV protective tape has chemicals in both the tape and adhesive that block UV rays and make the tape resistant to both sunlight and heat. It can be used in both hot and cold climates without the worry of adhesive transfer resulting in a quick and clean removal upon project completion. Although more expensive than other tapes UV protective tape is very cost effective when the costs of clean up or repainting of entry thresholds are considered. Blue masking tape and blue sill tapes are the most common tapes for protecting thresholds. These low cost tapes work for short term protection only in areas of low heat or sunlight.
Buying a cheap bifold door may prove a disappointment unless you check carefully that the door you are buying will meet your needs and expectations before you order. Threshold ramps are designed to help you get over a small dip or rise. They work great for power scooters or wheelchairs as they allow you to span doorway thresholds or small steps that may otherwise would have an abrupt height gain or drop. These ramps can be fixed in place or portable. If you have an electric mobility scooter it is a good idea to have a threshold ramp. Even a 1-inch dip or rise can pose a significant barrier and could result in injury if traversed.
