How to waterproof and insulate the roof of rural self-built houses?

Before roof waterproofing, all pipes and roofs shall be smoke-proof. It must be done first, and then the slope of the roof must be found with cement mortar. Usually, the next layer of waterproof material in the middle and high valleys is used for waterproofing. Commonly used waterproof materials include JS composite waterproof coating, HG203 waterproof coating and polyurethane waterproof coating, and the cost of materials is 150, and the roof of self-built buildings in rural areas is flat-topped. In order to be waterproof and achieve the effect of anti-freezing and sun protection, the traditional construction method should be adopted, with cinder paving a layer on the roof and a slope, and perlite and cement mortar plastering a layer on the cinder as a whole. And wipe the slope. Cement mortar can be used as waterproof coating when it is dry. Cinder and pearl salt are both.

How to waterproof and freeze the self-built roof in rural areas! First of all, the roof of the house must be a flat roof with stone and cement quality! There should be drainage pipes around the flat roof! Prevent water accumulation when it rains! When the water is full, it will flow home along the stairwell! I said antifreeze! A one-foot-high compartment will be built on the flat roof! Winter is equivalent to separating the cold air! Play a warm role! If the roof is not waterproof! Tianshui will definitely flow home until it rains! If you don't make antifreeze! Winter is as cold as outside! I personally feel! Waterproof! Antifreeze is very important. Building a house at a friend's house! Be sure to be waterproof and antifreeze! Carpet laying. Usually, the package moves from the lowest edge position to the roof. The electrons formed in this way can prevent moisture from infiltrating into asphalt roof panels. It can also be used as a second defense barrier.

Unfold the tape. First of all, the tape must be placed at the cornice of the roof, set to the same height as the initial layer, and staggered and aligned at the joints. After cleaning Yuan Zhai, brush flexible waterproof paint or asphalt, and use 10 cm insulation board as insulation layer. At the same time, do a good job in roof drainage organization, especially flat roof, and refuse the existence of roof water. Then use cement mortar to find a flat place to find a slope. The coil is waterproof. Then you'd better make roof tiles. It is best to make a sloping roof. There is snow in the north and heavy rain in the south, which is beneficial to roof drainage. The insulation layer of magnetic building roof cannot use insulation layer with heavy weight and high thermal conductivity to prevent the roof from being overweight and thick. Do not choose thermal insulation materials with high absorption rate. When the roof is protected from moisture, the insulation layer will absorb a lot of water and reduce the insulation effect.

Roof insulation layer includes polystyrene board insulation roof, recycled polystyrene board insulation roof, overhead dark panel insulation roof, overhead glass surface insulation roof, insulation inclined insulation roof, inverted insulation roof and so on. Aerated concrete thermal insulation is widely used, and the thickness of thermal insulation layer is 50 ~100 mm. Some aerated concrete blocks are set overhead, and some are insulated with cement perlite, pumice, cement polystyrene board and bagged expanded perlite, which has good thermal insulation effect. There are many positive steps to lay waterproof layer on polystyrene board, an efficient thermal insulation material. The daubing method is to install polystyrene board on the waterproof layer to prevent the waterproof layer from being directly exposed to the sun, so as to delay aging.
