QFA-EXT-D-2"
[SS-QFAEXT-D]

The Exterior Grade QFA -EXT-2" Rolls consist of a 2" quilted fiberglass absorber with a Heavy Duty 10 Ounce Per Square Foot Exterior Grade Vinyl Coated Polyester, (VCP) Facing, sewn with Gore Tenara Exterior Grade Thread, and are used to reduce the reflection of sound waves or reverberant noise energy on construction sites where the product may be subjected to sunlight, rain, snow, and winds. It is commonly installed over wood fencing or on brick or masonry walls of buildings adjacent to a job site or a noisy piece of machinery. All products have a Class A flammability rating (per ASTM E 84).

Exterior Quilted Fiberglass Absorbers are fire safe, high performance acoustical fiberglass blankets that are used to reduce reverberant (reflected) airborne noise energy in many diverse construction, industrial, and architectural applications. Additionally, they are unaffected by moisture, humidity, dust, dirt, oils and most chemicals. QFA -EXT-2" flexible quilted absorbers are easily installed, will not degrade, and have extremely long service lives.
