Product Description:

Vapour Permeable Waterproof Felt Fabric Rolls

1) Introduction of  breathable membrane for pitched roof

  1.    Breathable Membrane is a water resistant membrane but with high vapour permeability, use as diffusion open roofing felts under pitched roof tile or vapour permeable barrier housewraps on timber frame walls

  2.    Breather membrane functions as a weather-resistant barrier, preventing rain from getting into the roof or wall assembly while allowing water vapor to pass to the exterior.

  3.    Breather membrane may also serve as an air barrier if it is sealed carefully at seams.

  4.    Breathable Membrane have good "water resistance", good "water vapor permeability", and good "air barrier properties".

Q:What is the car waterproof sticker material?
C. metal technology and other: metal technology refers to the aluminum plate and other metal plate through the machine to suppress the concavity and convex surface, and then made of metal paint color, and finally after grinding, drawing and other production of the car stickers (car standard); Area can not be too large, can only be used for a small range of iconic car stickers.
Q:Slope roof drains do not need to be waterproof
need. Roof waterproof layer regardless of which form and materials, constitute the entire roof of the waterproof drainage system, all the necessary pipes, flues, drainage holes, embedded iron and pillars and other roof out of the facilities, should be done in the roof waterproof Layer to properly handle the structure of the node, with particular attention to the connection part of the soil and the drain part of the water flow.
Q:How does the finished ventilator manufacturer waterproof?
Rooftop natural ventilator waterproofing measures are mainly two kinds, one is the traditional silicone, adhesive tape waterproof, the other is the structure of water, the national standard Atlas 11CJ33 "ventilation and light skylight" recommended the use of structural waterproof technology.
Q:What material waterproofing can be mixed with cement sand
Construction can also be used to produce waterproof pulp, waterproofing agent for the amount of cement 3 ‰ -4 ‰, the use of cement label not less than 32.5MPa.
Q:Why should the use of high pressure perfusion waterproof plugging method
High pressure grouting construction principle: is a special high-pressure grouting waterproof material through the high-pressure infusion equipment into the concrete crack structure extended until all the cracks (including the naked eye is difficult to meet) filled with water (water) with the cross-linking reaction, Release a large number of carbon dioxide gas, resulting in secondary pressure, high pressure and secondary pressure will be pressed into the elastomer and filled with all the gaps, to stop the purpose of leakage, it can be said that the best performance of plugging material,
Q:What is the car material so that the car can be waterproof, in the rain will not leak in?
Engraving process car sticks A. knife engraving process: refers to the computer will be vector graphics input knife machine, the knife will be cut into a preset film shape, and then by hand will be different colors together Finished, and finally in the finished product posted on the surface of a layer of transparent transfer film, after the stickers to remove the stickers; due to knife car paste production process is complex, high cost of materials, currently only suitable for individual car and Che Youhui team Small customization
Q:Nanning building waterproof material market where
Nanning this building waterproof coating does not seem to have a special market, waterproof materials like fast ring building materials market, Wan Tai Long have to sell, as well as Mingxiu Road and Mingxiu Road on both sides of the road have a heavy focus on waterproof materials and companies
Q:What is PE waterproof cloth and PVC tarpaulin
PE tarpaulin, anti-aging, anti-aging, anti-corrosion, light, easy to fold, relative to the PVC tarpaulin, PE tarpaulin cheaper price for the freight yard, the service life will be shorter.
Q:There is no formaldehyde in the finished putty
The current status of the market to buy regular manufacturers out of semi-finished products putty and formaldehyde has nothing to do, because the status quo countries also hit the product containing formaldehyde in the building materials, the current market traffic is relatively large for the water putty, putty powder which is natural mineral powder And water-based glue synthesis, because the product life long-term pollution-free, so that is impossible to contain formaldehyde, but engineering putty is usually on-site modulation, and in order to increase the adhesion of putty powder inside the addition of a large number of construction glue (Containing formaldehyde).
Q:A complete set of basement waterproof construction program
Second, the basement of the external walls of water leakage construction preparation 2.1 Technical preparation 2.1.1 Selection of construction methods Waterproof engineering is related to the use of the project an important indicator, it is the construction process of a key project, difficult engineering. The choice of construction methods and programs has a direct impact on the quality of construction. The underground wall of the project SBS waterproofing membrane with hot melt method full construction. 2.1.2 before the start of the project, the first organization of engineering and technical personnel to enter the construction site, to understand the situation, to further understand the characteristics of the project to solve the contradiction between the construction technology and the implementation process. 2.1.3 technology before the end of the construction of waterproofing works by the professional foreman in accordance with the construction drawings and the existing national norms require the actual situation of the project to the construction team in writing to the end. The contents include construction site, construction sequence, construction technology, construction level, node fortification method, enhancement site and practice, project quality standard, guarantee the quality of technical measures. And after the field technical person in charge of the strict implementation of the audit.
