Product Description

Roofing membrane,breathable roofing membrane,waterproof roofing membrane,permeable roofing membrane,membrane for underlay,roofing felt,waterproof roofing felt,Bituminous roofing felt,Bituminous membrane,Asphalt Felt,Bituminous felt,


It is designed for use as a type of underlay on roofs with tiles, slates or steel tiles. This underlay can be also used to provide extra security under tiles when sub-roof sheets are used. The edges have been reinforced in order to boost its tear resistance, improve the nail holds and enable the product to withstand rough treatment.
It has a glass fiber core that has been impregnated with bitumen. The core is coated on both sides with stabilised bitumen and the surface is coated with fine slate granules. The edges of this underlay has been reinforced with polypropylene felt to provide excellent tear resistance and good purchase for nails.

Q:Under what wall does it need to pave glassfiber mesh completely? Plastering inner wall or exterior wall, which one is it applied to?
This is just an industrial standard. It is called adhesive sticker, but it is rarely used to do so because of cost. And it is rarely used at home. As for paving mesh completely or joint tape, it can be plastering exterior wall. Plastering inner wall is generally used in seam crossing of wall (there is mesh specially for jionts, but it is required that plastering inner wall is used in most fiberglass mesh. It's too expensive, and there is no need to do that.)
Q:The advantages of alkali-resistant glass fiber mesh cloth
Alkali-resistant fiberglass mesh is softer, so it just disperse the deformation stress (deformation stress beyond deformation temperature ), but unable to share the tension of adhesive layers. When the basis weight of fiberglass mesh increases, the greater the tensile bond strength of brick, but the increase is not obvious.
Q:How to choose glass fiber gridding cloth for thermal insulation of internal and external walls?
It depends on metope need. General speaking, gridding cloth is used due to its crack resistance.
Q:Joints of different materials on wall need to be pasted with steel mesh or fiberglass mesh, and the parallel position with beam column must be pasted, then what about the unparallel position?
When it deforms but there is slab staggering, it would be curved. Pasting in advanced should be till that plastering is parallel with wall. It also needs to be pasted. The unparallel position should on the same wall surface. There will be cracks and plaster might fall off.
Q:Mesh cloth and Dacron cloth, which one is better?
1, Mesh cloth is better. 2, Mesh is not necessary. Only if there are many cracks on the wall, mesh cloths will be accessible; if the cracks are acceptable, bandage can be used to cover them. 3, when paste mesh or use bandage, the binder used must be white latex, and of high quality. 4, Putty, for filling the joints in wall treatment, can be made by gypsum powder mixing with glue, or we can just use finished products to fill putty. When level a wall, we can use talcum powder, heavy calcium carbonate powder(whiting powder) with addition to glue, and stirred into putty, or finished putty is available, but white latex is needed in the finished putty to increase adhesion of putty. 5, Water-proof putty is used only on the walls which are disturbed by moisture, like the metope of toilet door, not with other parts. Of course, relying on water proof putty completely would be better than ordinary putty, but the cost has increased enormously.
Q:How much does mesh paving cost??
Around ¥10.
Q:What is the function of exterior walls insulation alkali-resistant mesh?
Because fiberglass mesh can serve to improve the mechanical strength of the insulation system, crack resistance and enhancement in the insulation layer, and the alkalinity of plastering mortar have a corrosive effect to the glass fiber mesh, the use of alkali-resistant resin-coated mesh can have a better strength retention rate in the plastering mortar, so that the insulation plastering mortar has good durability and long-term crack resistance.
Q:What CE certification should glass fiber gridding cloth be done?
CE certification is a kind of safety certification and regarded as a pass of manufacturer to Europe market.
Q:Is there a need of mesh for the renovation of the old hous? Will this make the wall crack?
It is ready to re-paint the emulsion paint. It is not necessary but to remove the base putty.
Q:With what to cut fiberglass mesh?
The width of fiberglass mesh is fixed in the production process, then it will become rolls. Manufacturers sell products of different widths, so you just need to purchase meshes according to the procurement requirements.. If you do not need special width, you can customize it at the factory. If it has to be processed into rolls of different width, hand saw is suggested because the temerature generated by rapid electric speed won't be lost in a short time. But the high temperature will melt glass, increase resistance, damage saw web, and even burn the circuit.
