The original function of the balcony is not to keep warm, but only a stand or storage room, so the general wall is relatively thin, insulation performance is relatively poor. The balcony is generally isolated from the interior space, and many people have removed the door to make the interior space appear spacious. The transformation of old houses is often faced with the problem of reforming the balconies. No way, the old houses are mostly small in size and valuable in space. Therefore, everyone has focused their attention on the balconies. Instead of knocking out the balcony door and becoming part of the living room, you're transforming the balcony into a kitchen. Then Xiao Bian came to tell you about the balcony insulation method and how much money to keep the balcony a meter .
Balcony insulation method
The use of polystyrene board (XPS board) flame retardant and ordinary two, flame retardant is also divided into A and B grade, plus polymer cement mortar, building materials city can be found, flame retardant polyphenylene plate prices about For a price of 500 yuan per cubic meter, about 50-60 bags of 50kg of polymer cement mortar, this type of mortar is divided into adhesive type and crack resistant type, and the adhesive type is used to apply polystyrene board to the wall surface. The crack-resistant type is used for painting the surface and then painting. If you are tiling, you can use the adhesive type, and use alkali-resistant nylon mesh or metal mesh.
The construction process is: wet the balcony wall first, then apply the polyphenyl board to the wall with the polymer cement mortar, stick it well after drying (the best 48 hours in 24 hours), thin on the polyphenyl board Wipe a layer of polymer cement mortar and then immediately put an alkali-resistant nylon mesh or metal mesh on the polyphenylene plate and then wipe a layer of polymer cement mortar. The thickness can be about 1cm (the thickness of the metal mesh is more because of the larger area, It is unlikely that all parts of the metal mesh will adhere to the polyphenyl board. If the thickness of the nylon mesh can be controlled at 0.5cm), it can be tiled after 24 hours. Tiles can use either polymer cement mortar or plain cement if you use tile adhesives. The previous procedure was to level the polymer cement mortar when it was applied to a nylon mesh or metal mesh.
It is recommended to use polymer cement mortar tiles. The first is to stick firmly, and second, to save the trouble of buying ordinary cement and sand, or tile adhesives. Note: In addition to tiling, other processes must use polymer cement mortar, can not use ordinary cement. Because the polymer cement mortar already contains rubber powder, its adhesive force is larger than ordinary cement.
The balcony insulation is divided into two kinds of insulation layer exterior putty brush coating finishes and tile finishes;
There are two ways to make the outside tiling insulation:
First, the balcony space is large, you can build a layer of brick outside the extruded board or benzene board (light weight or red brick steep build); then plaster, pull hair, tile;
The second is the small balcony space, you can do in the extrusion board or benzene board facade of light steel, a layer of cement board, hanging wire mesh, plastering, pulling hair; then tiling;
Also keep in mind: balcony wall expansion coefficient is relatively large, tiling to stay as good as possible expansion joints to avoid cracking;
Balcony insulation for external brush coating can be made of light steel keel on the outer surface of the extruded board or benzene board, and a layer (or two layers) of plasterboard is applied. After the rust prevention and anti-cracking treatment is finished, the water-repellent putty is scraped and polished. Smooth, brushing paint with good scrub performance;
Thermal insulation method of balcony:
First, the use of polystyrene board insulation below the balcony window.
Second, use rock wool insulation below the balcony window.
Third, the use of ceramic plates in the balcony window as insulation.
The three methods are to use a material with good thermal insulation effect to make the insulation layer on the balcony wall to cut off the exchange of indoor and outdoor hot and cold air.
However, in terms of specific practices, several points should be noted:
1. In either case, skeletons must be made on the wall with wooden keel or light steel keel to ensure long life.
2. When using wood keel, specifications should be slightly larger, and the best section size is not less than 5×10 cm.
3. Regardless of the type of keel used, the moisture treatment of the keel should be considered.
4. After the insulation layer is completed, besides the ceramic grain board, it is better to use the cement pressure board as the surface sealing plate, and then perform other treatments such as brush coating or tiling.
How much money to keep the balcony a meter
Mainly depends on your home balcony area, you can first measure, ask again, generally have a few thousand dollars, balcony floor must be careful when filling, must not use cement mortar or brick to fill directly, this will increase the balcony load , danger. It is best not to fill the balcony floor. If you have to fill in, you can use light foam bricks to minimize the balcony load. Insulation balcony bar. 130-150 about a meter. Material 70-100 or so, artificial transport installation of other 50 or so. Glass balcony guardrail is slightly more expensive than 300-600 range. Mainly depends on the type of glass.
Summary: The related information about the balcony insulation method and how much the insulation balcony is one meter is introduced here. I hope this article will be helpful to everyone. If you still have something you don't understand, you can leave a message to Xiaobian at the bottom. We will answer your questions as soon as possible.
