About 30% of heat are lost in the winter through outer door. To create favorable temperature condition in the apartment, it is necessary to warm not only windows, but also metal doors. For this purpose there are certain small cunnings. High-quality warming of door can be made by means of polyfoam, felt, old blanket or felt matter.
Instruction
1. For a start make frame which fix by means of cross partitions to door of wooden rails. Prepare Reechki about 30 mm wide and about 20 mm thick. Make openings at doors and self-tapping screws attach plate to the basis of door. Close up deepenings which remained from self-tapping screws glazing compound, jam abrasive paper, and then hide varnish or oil paint.
2. Take further polyfoam (its width ideally has to equal to depth of internal cavity of outer doors) and lay it inside. It is necessary to fill all space. In order that it was more convenient to work further, fix it in door by liquid nails. Fill gaps between single sheets of polyfoam with polyurethane foam. After its drying you pass in the next stage.
3. Take laminated by fibreboard and hide all this design from polyfoam. For fastening of this material use self-tapping screws on metal. Previously drill openings, then the self-tapping screw will be easier to be twisted in metal. Record the sheet fibreboard in door cloth in necessary situation with the help of clamps. Take drill, insert drill a little less than diameter of the self-tapping screw. And directly through the sheet fibreboard you drill opening and screw in in it the self-tapping screw. It is better to begin fastening with self-tapping screws from top to down, then in process of fastening the sheet fibreboard will at once and be leveled.
4. Warming of flat metal doors can also be made by means of the existing sealants which are on sale in hardware stores. However, it is simple to make them also the hands. For this purpose cut dermatin strips 10 cm wide, fasten them that door perimeter length has turned out. Prepare also foam strips 3-4 mm thick longwise of leatherette.
5. To condense slot between outer door and door case, take foam rubber strips, envelop them leatherette. Fix the received sealant along door case on all perimeter of outer door, except threshold.
