Insulation nails, in the South called "exterior wall stud (nail)", mainly used for exterior insulation system, insulation board fixed, plastic insulation nails, into a variety of specifications, according to the given insulation widely used in the construction and decoration. Insulation nailed to the house widely used in insulation. With anti-aging, anti temperature change, corrosion, cold and heat; high capacity, high pressure, good tensile properties; load is not easy to deformation, moisture, slow vibration, noise absorption and sound insulation characteristics, easy to install. Insulation is insulation board nail fixed to the wall on the expansion of a special plastic nails. Insulation nail consists of three parts: First, nylon casing; second casing of galvanized steel screws; third, before the nylon disk casing (insulation board for the gland). Its length under the insulation thickness varies. Widely used in wall housing the anchoring area. It has anti-aging, anti temperature change, corrosion, cold and heat; high capacity, high pressure, good tensile properties; load is not easy to deformation, moisture, slow vibration, and good thermal insulation characteristics. Easy to install, no special installation tools. Galvanized screw a good solution to corrosion, durability, and low heat transfer performance of nylon, no cold bridge in winter, energy-efficient.
