Door Threshold / September 17, 2018 / Martine Letourneau.
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.
New jambs allow for air-tight vinyl weather stripping and adjustable thresholds with vinyl door bottom sweeps. Low maintenance fiberglass or metal doors are sandwiched with foam insulation. And doors with windows come with thermal glass. Installing a new door in an existing older home has become a highly desired remodeling upgrade. These days installing a pre-hung entry door system (including jambs) to new wood stick frame construction is generally pretty straight forward; you can just nail or preferably screw through the jambs to the framing studs behind. If adjustments are necessary just pull the nail or back out the screw re-align the jamb using builders shims and try again.
Doors can be protected with temporary cardboard door protectors available from a variety of manufacturers. Several protectors are not only made from recycled cardboard but can be reused and recycled entirely again making these protectors truly green. The first protector to market and most popular is DoorGuard. It is a truly green product that uses recycled cardboard for the door protection with natural rubber bands for attachment. Another popular protector is the 1-2-3 Doorshield product. This protector is not recyclable as it uses plastic Velcro for the door attachment.
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.
