Двери и окна в любом доме являются самыми vulnerable in terms of heat retention. Old wooden windows can be easily replaced with new ones with energy-saving double-glazed windows. But you will most likely have to insulate the door yourself, even if it is a modern metal product, with lining and even with insulation inside the structure. Wooden doors, despite the very low thermal conductivity of the material from which they are made, do not cope well with the task of retaining heat in the house without insulation. In addition, due to natural deformation processes, subsidence of the canvas or frame, cracks may appear through which heat will easily leave the house.
Do-it-yourself insulation of the entrance doorminimizes heat loss and saves the budget for heating the house. Solving the problem of insulating the front door means eliminating the possibility of heat loss and, accordingly, reducing energy costs.
Warming of the door around the perimeter of the box: features
Scheme of insulation and reinforcement of a wooden door.As a rule, if a new metal door is installed, it may already have a seal around the perimeter, but if it is missing or has become unusable, this type of work will need to be done. Between the frame and the door leaf, even with an ideal fit and installation, there is always a gap at the point of their junction. For a long time, foam rubber products were used as a seal: inexpensive, easy to install, but very short-lived. After several years of use, they had to be replaced, as they ceased to cope with their task, crumbled and fell apart. Rubber and especially silicone seals have significantly better characteristics. They are elastic, due to which a tighter fit of the door leaf to the frame is ensured, they are resistant to cracking. When choosing a seal, the width of the door rebate is taken into account, and the thickness is determined by the gap, which can be measured with a caliper. The required length is selected along the perimeter of the frame. If insulation is performed around the perimeter of a wooden door, it may be necessary to make a groove in the frame - this will ensure a tighter and more even fit. The seal is installed in two ways. If it is a self-adhesive version of the material, then the protective film or paper is removed from the sticky side and glued to the frame. It is imperative to do this gradually, as the seal is glued. Return to the table of contents</a>
How to qualitatively perform the thermal insulation of the entrance door from metal?
Construction of a metal door with an internalinsulation. Many wooden entrance doors have been replaced by metal ones, which are more reliable. But metal is a good conductor of heat, and losses from a house protected by such a door will reach 30%. The most common option is to refine the door using decorative panels made of MDF, plywood or wood. But if this is not enough, you can additionally insulate the door from the inside. For this, various types of insulation can be used: mineral wool, foam, various types of foaming resins and other materials. When choosing, you need to take into account their related characteristics for sound insulation, fire resistance, as well as the design of the door itself, which can be collapsible or solid. In collapsible designs of entrance doors, a layer of insulation is laid inside. The most suitable types of materials are slabs, for example, mineral wool or foam, as well as rolled products (foam rubber is often used for these purposes). And liquid nails are used for their installation. If the door is solid, foaming materials can be used, which are applied to the surface or, when the structure is closed, sprayed inside through functional openings for the peephole, lock, etc. An additional or, in some cases, the only option may be external insulation: for this, a decorative coating is used for the door leaf, independently or in a set with the use of thermal insulation materials. First, in the second option, a frame is made for the insulation, and then closed with a decorative panel on top. But a lightweight version is also allowed, without a frame: in this case, the insulation is glued to the door leaf with liquid nails, and then the sheathing. Return to the table of contents</a>
Features of balcony door insulation
Scheme of insulation and sealing of metaldoors around the perimeter. It is not only the entrance door that is to blame for heat loss from the apartment; you should also pay attention to the balcony door, even if it leads to a closed or even insulated balcony or loggia. One of the most effective ways is to completely replace the old balcony block with a new one, for example, made of metal-plastic with double-glazed windows. But if this option is not relevant for some reason, you need to insulate the old door. It is quite possible to insulate a balcony door yourself: for this, for example, you will need the most common tools (hammer, paint knife) and minimal skills in working with them, insulation, glue, liquid or furniture nails. If you need to eliminate cracks in a wide gap when the door is closed, you can use seals or make foam rollers yourself. Next, you should insulate the lower part of the door, for which you can use any insulation. Since the balcony door is often collapsible, the insulation can be easily laid inside, securing it securely with glue or nails. If the insulation is carried out from the outside, then you should take care of its protection, for example, with leatherette, plywood, fiberboard or other materials. Be sure to check the upper part of the door with glass for cracks: if there are any, they must be removed. For this, you can use silicone sealants: they will not let the cold through, but, if it is necessary to replace the glass, they can be easily removed. Return to contents</a>
Warming of the wooden entrance door
This door is made of solid wood,therefore, it can only be insulated from the outside, both on one and on both sides. The insulation can be almost any, but foam rubber is the most convenient to work with. For decoration, you can use leatherette or a cheaper option - leatherette. It is also permissible to insulate and simultaneously ennoble a wooden door using decorative panels. But in this case, it will be necessary to replace the frame, since the thickness of the door will increase, and if such large-scale work is not included in the plans, you should opt for the first option. Insulation work should be carried out with the door removed. It is recommended to carry out antiseptic treatment and clean its surface from dirt. After this, a layer of insulation is placed on the canvas and lightly fixed to the surface with small nails. The next step is to fix the upper decorative layer with nails with decorative heads. It is imperative to monitor the tension of the material on the surface and avoid the formation of folds. Marking for fixing the material should be done in advance, which can even be done in the form of a certain pattern. At the final stage, the door is returned to its place and placed on the hinges.
