breathable foil Facing used under roof decking, under attic rafters, over existing attic insulation, in floors, walls and crawl spaces, and in industrial and commercial buildings to block radiant heat coming into house during the summer and retain indoor heat generated during the winter as a radiant barrier for its low emissivity.

Moisture condensation could happen when a radiant barrier is installed in buildings, particularly in extremely humid or cold climates like in basement room. Water vapor in the air can condense on the surface of the roof sheet, insulations can become wet and lose some of its insulating value, water spots can appear on the ceiling and under severe conditions, and the ceiling framing can rot.

To avoid water damages to ceilings or risk of corrosion due to condensation under roofs, a micro-perforated radiant barrier could substantially assist in the reduction of condensation and prevent potential moisture problems.

Perforated materials are suitable for many types of retrofit applications and for some new construction in places of high humidity and in areas of cold climate.

Aluminum foil insulation as a radiant barrier stops up to 95% of radiant heat transfer which improves the performance of the insulating material.Fiber glass scrim reinforced for strength and durability. Aluminum foil insulation provides an efficient, space saving, and healthy method of temperature control and energy savings

Perforated FSK foil a FSK Facing (Foil-Scrim-Kraft) with tri-directional fiberglass scrim and 50~60gsm Kraft. Micro-perforated FSKF radiant barrier is a breathable material; in other words, it can allow harmful moisture and humidity to escape and eliminate condensation. Multi-hole will help absorb acoustic.

Perforated FSKF foil supply better radiant performance and also allow moisture emussion.

Roll Width: 1.00m to 1.35mm

Roll Length: 60m to 2500m

Considering perforated FSK & FSKF is not suit for extremely humid environment since Kraft in it can absorb moisture easily, therefore FW Breathable foil (Foil-woven fabric) which with PE or PP woven which is water proofing as liner, was designed for this situation. It can allow harmful moisture and humidity to escape and eliminate condensation.
