Door Threshold / September 15, 2018 / Leala Melanson.
Of course youre going to check the concrete threshold step for level. Carpenters never assume anything right? Measurement of the exterior brick opening overall height from threshold to lintel will be noted. Any further uncertainty about whether a house was built with masonry walls can be at least partly resolved by measuring the exterior brick opening overall width. A width measurement slightly off by about one-half inch from the nominal brick opening is a sure tip-off that youre going to be facing the direct fasten to masonry challenge. Adjust your installation estimate accordingly for some extra labor.
These protectors can be made from molded plastic or cardboard. Pre-molded plastic protection works well for jambs with standard door casing widths. For larger jambs there are several wrap-around jamb protectors that work similarly but are not molded to an exact casing size. These reusable protectors provide excellent protection however they are the most expensive jamb protectors in the market. Less expensive cardboard protectors wrap around jambs in a similar fashion and cost considerably less than their plastic counterparts. These are available from a wide range of manufacturers can be purchased online or in construction supply stores as well.
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.
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.
