A damp proof course ( dpc ) is a physical barrier inserted into the fabric of a building to stop water passing from one place to another. This can be on a horizontal plane, stopping water rising up from the ground by being sucked up by the dry masonry above, or vertically to stop water passing from the outside of a building, though the masonry, to the inside. Dpc's have taken many forms through the ages and one of the earliest forms was to use a layer of slate in the construction. Slate is still used but the less expensive plastic version ( below right ) is now more widely used.

Flame retardant waterproof membrane enhances the safety of the building.PANZHU WRAP flame retardant waterproof membrane is produced by the latest technology, with the function of self-extinguishing from the fire, which can effectively enhance the fire escape time for people and improve the building fire rating. Flame-retardant breathable membrane is also suitable for steel structure roof which needs electric welding operation. Fire Retardant Breather Membrane raise the level of building protection to a new standard. Based on the latest patented technology. Fire retardant breathable membrane can reduce the spread of fire more effectively and avoid causing more losses. When the flame meets the Fire Retardant Breather Membrane, it will stop advancing, slowly extinguished, until the flame disappears. The latest patented technology not only retains the excellent breathable performance, but also increases the flame retardant performance, which can not only effectively improve the energy-saving efficiency of building envelope, but also increase the safety of the building, thus making it the ideal protective layer of the building. Flame retardant breathable membrane Product features: Easy installation, Anti-aging, Long service life, Strong waterproof ability, the hydrostatic pressure can reach more than 2m, and has a unique function of vapor permeability. Flame retardant breathing membrane can discharge the water vapor inside the enclosure structure and ensure the thermal performance of the insulation layer in order to extend the service life of the building. Fire class: Class B1 which is equal to the CE standard Fire class E. Flame retardant house wrap Application: on the outer side of Curtain wall insulation, steel structure insulation, cladding insulation, prefabricated building insulation, Passive House insulation and slope roofs of many kinds. The roof breathable membrane is installed upon the roof insulation layer, which is suitable for slope roof with purlin or without purlin and roof system of steel structure. It has excellent waterproof performance and high strength. It can effectively reduce the risk of condensation phenomenon, air leakage and convection heat loss in order to protect the insulation layer perfectly.
Waterproof membrane uses the very latest technology of high quality microporous membrane.This material has many tiny holes which permits air vapor to get through but prevents water molecule to get through. Thus the performance of waterproof and breathable. Breathable membrane consists of three layers: Outer shelter layer, middle function layer and inner shelter layer. The two shelter layer keeps the membrane durable in every kind of using environment. House wrap advantages: Breathable membrane for roof air tightness:Correctly installed PANZHU WRAP can protect the house from strong wind and reduce the thermal bridge phenomenon in the inner house Breathable membrane for walls water tightness: Excellent waterproofing performance with 2 meters water column up and two hours water tightness Breathability : 1063g/ã?¡.24h or 68 US perm The house can breath freely with PANZHU WRAP and keep away the mold and rod. Durability: PANZHU breathable membrane has passed the national aging test.Tensile strength 232N/50mm.
Waterproofing membrane reflective can not only reflect the heat radiation from the roof, but also has the function of breathable. Reflective Waterproof Membrane adopts vacuum aluminum plating method to add a layer of aluminum foil on the surface of the waterproof membrane. On the one hand, Reflective Waterproof Membrane has the effect of heat reflection; on the other hand, the fireproof effect of the waterproof membrane can be improved; Third, the service life of the waterproof membrane is extended.Reflective Waterproof Membrane is suitable for any wall system that needs moisture protection.This low emissivity membrane is particularly effective in lightweight wall structures, such as timer frame or steel structure buildings, as well as masonry and internal insulation upgrades. In winter, the reflective breathing membrane can effectively block the diffusion of indoor heat radiation, reduce the loss of indoor heat and strengthen the thermal insulation effect of the building. In summer, reflective breathable membrane can play an excellent role in heat insulation.The reflective breathable membrane reflects the outdoor radiation, reduce the building's absorption of heat radiation so as to keep the indoor air cool and reduce the refrigeration energy consumption. Therefore, the reflective house wrap can be effectively applied no matter in what kind of insulation climate zone, with good thermal insulation, waterproof and vapor permeation effect and play a significant role on the building energy saving.
