In the manufacturing process, close attention is paid to every detail and only the finest quality materials are used. The SNAP-N-LOCK™ panel is backed by a 10 year limited manufacturer's warranty. The waterproof adhesive has the highest ICBO approved rating and is carefully vacuum bonded using the latest technology.

Dimensional inspection performed in the shop to insure that length, width, squareness and thickness are within specified tolerances. Further shop testing is done to make sure that the finish meets applicable standards.

The panels are also put through extensive and rigid testing to insure they continue to meet or exceed building code requirements for wind, live and dead loads. The SNAP-N-LOCK™ panel is capable of supporting 57 lbs. live load per sq. ft. combined with various wind loadings up to 120 m.p.h.

Strict fire testing of the SNAP-N-LOCK™ Insulated Panel was performed in accordance with UL standards. In the UL Test 1715, otherwise referred to as a "room burn test", the metal skins performed extremely well to the intense heat conditions and the fire-retardant expanded polystyrene foam core didn't contribute to the spread of the fire.

Additional fire tests administered to the panel include ASTM-1929, which tests how the panel responds to flash and spontaneous ignition, ASTM-119, a one hour burn test on load bearing and non-load bearing walls, and ASTM-E84-95, which determines surface burning characteristics. In all these tests, the panels well exceeded industry standards.

In addition to the standard required testing, it is important to note that the solid core construction eliminates the "chimney effect" that causes fires to spread quickly through stick built walls. Drywall will further improve the fire barrier rating.

Structall Building Systems recommends that the interior walls be constructed of steel studs with a drywall exterior finish. This method of construction has a STC of 36 (sound transmission rating), similar to that of brick.
