Door Threshold / September 18, 2018 / Pauline Francoeur.
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.
5. TOP HUNG OR BOTTOM ROLLING Some bifold doors are hung from the top to allow for a minimal threshold at floor level but with all the weight of the door being supported from the top a substantial upgrade of the lintel is normally required for strength and stability. Bottom rolling folding doors are a cost effective and popular alternative since the weight of the door is carried at ground level rather than suspended from the lintel. Whether you decide on an aluminium upvc or hardwood bifold door it is a major purchase for your project and one that should be carefully considered to ensure the very best value for your money.
Garage door insulation is essential with wooden doors as you cannot allow any water to get in to penetrate the wood. You must have a high quality threshold sealant to help prevent rotting and severe damage to your door. The great thing about using wood though is that if it does endure wear and tear over the years it can be reconditioned without the need to replace the entire door. The most used type of door however is the steel door. You will see this one on most garages across America. Steel is extremely strong and robust and is impervious to rust. This gives you great peace of mind that the door will last for many years to come.
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.
