It involves a vinyl strip with fins, designed to contact the threshold. Finned door bottom weatherstripsįinned door bottom weatherstrips are easy to install, and typically inexpensive. The alignment of the interlocking channels is critical, and requires professional installation. They are very durable and very effective at air sealing, but relatively expensive. Interlocking metal weatherstrips are perhaps the best bottom weatherstrip system (see image at left). Prices are lower than those of interlocking weatherstrips, shown below. Door Shoe weatherstrippingĭoor shoe weatherstrips use a vinyl insert, or sponge rubber tubes. There are anyway different types of door bottom weatherstrips, with different prices and different levels of effectiveness. Besides, their design is also much more effective at sealing. Since they do not hang down like sweeps, properly installed door bottom weatherstrips will never drag on the floor covering, which increases their lifespan. There are several types of door bottom weatherstrips, all with the same basic mechanism, shown in the image at left once installed the bottom weatherstrip closes the gap between the threshold and the door. Ideally, the sweep should rest lightly on the floor (or on the treshold) when it is in the closed position.įollow the manufacturer's installation instructions. They just have to be mounted (using screws or nails) on the door's interior side (in the case of in-swinging doors) or on its exterior side.īe careful not to have it too low it will cause the door to drag which will wear down the sweep. Avoid adhesive door sweeps.Ĭommon door sweeps are made from aluminum or stainless steel and have a brush of vinyl, plastic, felt or sponge some are retractable - to avoid dragging. Examine the doors, and tighten their screws, hinges and strike plates, if necessary.ĭoor bottom weatherstrips (and some door sweeps) require also a threshold that's important to seal the gap, and to allow the door to swing without touching the floor covering. Prior to weatherstripping your doors, fix any possible problems with them. 1- Door bottom weatherstripsīasically there are two types of weatherstripps for door bottoms:Ģ) door bottom weatherstrips (door shoes, finned door bottoms, interlocking channels.). There are many cases – excessive wear, poor fit… - where replacing the entire door is the best option. Make sure that there isn’t problems related with the foundation settling, termites and rotting.Īlso take into account that most modern door weatherstrips have compression and steel magnetic weatherstripping, and that it may not be possible to find an exact match to the weatherstrip of older doors (tack on vinyl, metal weatherstrip).Otherwise, it will cause the top part of the door to lean away and be a source of problems, including wear and improper fit of the weatherstrip Fix possible problems with stripped hinge screws or loose screws screws should be tightened, and stripped screw holes repaired.This type of problems should be fixed before the installation of a new weatherstrip. Make sure that the door is not warped, with non-parallel jambs, or improperly installed, and see if the threshold is well adjusted.Doors should be both airtight and watertight.Įxtended use may cause door weatherstripping to fail, but there are factors that should be addressed before replacing the seal. Before replacing door sealsĭamaged and misaligned weatherstrips can be an important cause of energy waste. Typically, the gaps at the sides and top of your doors aren't important sources of drafts and air leakage but they can still be important for home energy efficiency. That gap is often a major air leakage area, and should be fixed. Pay attention to the gap at the bottom of your exterior doors (front, back and side doors). That's very important for home energy efficiency. Door Weatherstrips for home energy improvementsĮxterior doors should be airtight.
