Door Threshold / September 15, 2018 / Leala Melanson.
What is a high door threshold? This would be any doorway that has a threshold that you have to step over or a threshold that is higher than the surface you are walking on. These safety problems are obvious the high door thresholds are a trip hazard and for elderly people can be difficult to step over. Handicapped people in wheelchairs or motorized scooters wont be able to access these areas unless there is an alternative doorway that provides access for their wheelchairs. Usually the high door thresholds are located in a garage where someone has either made a mistake during new construction or simply figured that it would be easier to install the door a little higher and to remove the concrete foundation footing to install the door properly.
You can have it made from steel wood or even aluminum. They are all effective but all require some sort of seal to fill in the garage door threshold. Here is some information on the various types of garage door available. The material used will determine the type of threshold seal that you require. Wood is probably one of the oldest and most used materials. It certainly has a great deal of charm and is still preferred by many over the more modern metals and plastics of the modern world. They feel that the wood gives a character that the other materials just cannot deliver.
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.
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.
