Three layers composite nonwoven fabric,also called polypropylene and polyethylene waterproofing membrane.It's formed by spunbond nonwoven fabric,the middle layer is LDPE film.The characteristic is waterproofing, breathable, good tensile, anti-skidding and environment-friendly .

Our breathable membrane is just used on the insulation layer, like on the top of glass wool or other insulation material, and it is just under the roof tiles or plate. It is good moisture permeable (breathable), allows the moisture to pass through it and keep the drop water outside. It is also good waterproof and wind proof functional. Light weight and cheap price make it more welcome than traditional bitumen roof felt.
