Door Threshold / September 15, 2018 / Leala Melanson.
Not only do threshold ramps allow entry for scooters and wheelchairs they also help prevent tripping injuries. These ramps provide greater and safer access for all. Rubber plastic and aluminum are the most common materials used in threshold ramps. Rubber ramps are commonly sold to clear heights up to three inches. They can be used indoors or outdoors and are durable. Rubber ramps can be cut and trimmed to customize the needed height or size. They work great for door thresholds and small steps with the capability to support the weights of up to 850 pounds. Ive always enjoyed installing residential entry doors.
But what about retrofitting a new entry door system in an older home built with cinderblock masonry walls? You cant use the same technique of just nailing through the jambs the masonry will just deflect and bend a regular framing nail. Cut nails might possibly work but the chances for jambs alignment adjustments are slim to zero while the chances of masonry cracks or half-moon hammer head marks in the jambs are almost a given. Masonry screws need to be started in pre-drilled cinderblock holes which can be drilled through the jamb but Ive never been satisfied with their holding power alone where the cinderblock is prone to crumble around the holes while adjusting screws and snugging shims tight. Experience has taught me to always insert plastic expansion sleeves in the cinderblock to properly fasten masonry screws.
Choosing the right bifold door for your project is an important decision and one that should not be taken purely based on cost alone. Your budget will naturally have an influence on your buying decision but there are other important factors that need serious consideration to ensure you are not disappointed with your purchase. Here are the top five points that are regarded by many as the most essential research when considering a bifold door purchase: 1. THERMAL PERFORMANCE Since most bifold door installations will be subject to compliance with building regulations it is important to check that the folding door you are about to buy will meet your local authoritys interpretation of current building regulations in terms of overall U-value performance.
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.
