Экологичный Кровельные Подложка

The roofing membrane is also called breathable membrane. It is a functional membrane which is laid on the thermal insulation layer. It is applied to the composite outer wall or sloping roof of the wall curtain, profiled steel sheet, steel (wood) structure, masonry and so on.Material: PP nonwoven fabric+PE breathable film+PP nonwoven fabricBreathable roofing underlay1).Excellent Performance at water resistance2).Light and thin, antiskid, with good low temperature flexibility, suitable for construction in different condition.3).Improve water-tightness of building, protect the construction from the invasion of wind and rain, protecting the structural materials and equipments inside roof and wall.4).High tensile strength and elongation rate, highly flexibility at low temperature5).Used for roof construction for sloping roof of the wall curtain, profiled steel sheet, steel (wood) structure, masonry and so on.On the surface, the aluminum foil can be coated which is called reflective roofing underlay.It is a new eco-friendly and heat insulation material which is soft, light and easy to be paved. It is composed of aluminum foil+PP nonwoven fabric+PE breathable film+PP nonwoven fabric. It has no odor and toxicity; It can highly reduce the harm from ultraviolet radiation that can penetrate through sheet iron, concrete, wood and other heat insulation materials. It has the functions of insulation, heat-reflection and anti-radiation, it also has good moisture-barrier, heat-preservation and energy-saving functions. Characteristics: 1. No odor and toxicity, Environmentally- friendly; 2. Light, soft, dust free, fire retardant, easy to be paved; 3. Heat reflection, heat insulation, and sound insulation, anti-radiation and shielding. 4. Moisture barrier, waterproof, good sealing property, heat preservation, energy saving.. 5. Moisture barrier, heat insulation, heat preservationIt can also be strengthened with the fiberglass added. vapor barrier, aluminum foil coated vapor barrier Vapor barrier is compose of PP nonwoven fabric+PE breathable film. With the functions ofair impermeability, waterproof and dampproof, it is widely used in building construction.Vapor Barrier is laid between base of roofing and insulating layer. It can strengthen the air impermeability and water-tightness of building.Vapor Barrier as part of the internal lining will help to reduce the rate of heat lost by convection through the building fabric.Features:(1) good tearing strength, water proof, good breathability, soft handle,(2) heat insulation, Excellent performance breather membrane(3) Constructed from high tensile spun bond(4) Highest levels of water resistance(5) Full moisture vapor permeability(6) Breathable underlay for roofing, also widely applied in medical(7) Eco-friendly to be completely recyclable(8) Antistatic, UV resistantAluminum foil coated vapor barrierWith the aluminum foil coated, it can block radiant heat coming into house through the roof during the summer and retain indoor heat generated during the winter.A reflective barrier prevents up to 97% of radiant heat transfer which indirectly improves the performance of the insulating materialAluminum foil provides an efficient, healthy method of temperature control and energy savings.
