How to insulate a metal door? To make housing more equipped and comfortable, the owner needs to take care of this. Firstly, the entrance to the housing should be fenced from extraneous high-quality entrance door. Most often in such cases, a metal front door is used.
Each owner expects that when buying a metal door, he will ensure the maintenance of warm air in the apartment and will not allow cold impulses to the winds to go from the street into the dwelling. Unfortunately, the metal door does not always correspond to these expectations. You need to take the door to the choice of the door that will insulate and protect housing from the cold. When choosing a door, you need to pay attention to its quality, not low prices. If you buy cheap goods, then you will have to spend money on insulation. If you need to insulate the door or gate gaps, you need to use slats made of foam-material, plastic tube, bar in the form of a wedge, or a plank with a rubber strip. Before starting all the door insulation work, check the accuracy of the door entering the daily opening. Then you can start insulation. To get rid of external and internal cracks, it is necessary to use wedge -shaped wooden rails. First, measure the upper doorway. Then transfer these measurements to the rail. Then you can cut off the required amount from the rail. Keep in mind that on each side there should be a small stock.
A cut -out rail must be fixed at the top of the doorway from the outside. Check that the rail completely fills the gap and seal it. Following this principle, strengthen the entire doorway outside the perimeter. See that the cracks are filled. Then divide the entire perimeter of the rails into approximately the same distance. Start making self -tapping screws.
Do the same procedure on the other side of the door. Now the queue of thermal insulation of the threshold has come. Make a rail on the size of the threshold and place it outside. Choosing a rail, you will face many options, but the most optimal is the aluminum rail for the threshold, which goes with a fixed rubber strip. It is also fixed outside the doorway. The aluminum rail is also fixed using self -tapping screws. And the function of the rubber strip — protection and insulation of housing from the penetration of cold air.
