GRF is produced using over 90% recycle fibers and currently enjoys close to 70% of the facer volume for polyisocyanurate insulation in North America. Itīs high performance to cost ratio has made this both possible and sustainable. Technological work continues to improve processing ability on foam machines while also improving the structural characteristics of the product. GRF can be produced in widths generally between 48" and 51". |
Atlas Roofing Corporation has been a leader in the production and development of glass-reinforced felt facers (GRF). Atlas has the capability to produce GRF at both its Meridian, Mississippi and Franklin, Ohio facilities for shipment to North American and worldwide.
While GRF is primarily used in the polyisocyanurate manufacturing process, many other uses are under exploration. This felt product is a non-woven rolled web comprising a composite of organic & inorganic fibers. It is chemically treated to resist liquid foam-mix penetration, but it firmly adheres to the solid foam. Its success as a facer for polyiso foam board insulation has been proved by millions of roofing squares. | ||
Features & Benefits
Dry Weight = From 18-pounds per 480-ft sq. up to 36-pounds per 480-ft sq. as specified by customer Caliper = From 0.015-inches up to 0.036-inches based upon sheet weight Tensile, machine direction = 24-lbs pli minimum; CMD Tensile runs about 33% of MD Tensile Moisture = 3.0% to 6.0% as shipped Rolls can be supplied with either face out - per customer specification. Roll width and diameter can vary per customer specification up to a 72" roll diameter. The heavy paper core is typically 3" I.D. Other sizes can be available. Each roll will be tightly wound and be in such condition as to accept the core bungs for proper payoff while unwinding the roll. No roll splices will occur within 12" of core or within 4" of the outer diameter. Splices will be flagged on the side of the roll - i.e. clearly marked. A roll will not contain more than 2 splices. Each roll will be labeled with production date, shift, roll number, length, weight, and moisture. Packaging of rolls will depend upon the roll size ordered and per customer request. Loads will be maximized for weight and damage protection.
