Large supply of Zhejiang thermal insulation nails from manufacturers, wholesale various specifications at excellent prices.

Thermal insulation nails, also known as "external wall thermal insulation anchor bolts (nails)" in the south, are primarily used for fixing thermal insulation boards in external thermal insulation systems. Plastic expansion thermal insulation nails come in various sizes, depending on the thickness of the insulation layer, and are widely used in architectural decoration.


Thermal insulation nails are widely used in the insulation layer of buildings. They feature anti-aging, resistance to sudden temperature changes, corrosion resistance, and excellent heat and cold resistance; high bearing capacity, good pressure and tensile properties; they are not easily deformed after loading, moisture-proof, shock-absorbent, noise-reducing, and have good insulation properties. Installation is simple. Thermal insulation nails are a type of special engineering plastic expansion nail used to fix insulation boards to walls. They consist of three parts: a nylon sleeve, a galvanized steel screw inside the sleeve, and a nylon disc in front of the sleeve (used to cover the insulation board). Their length varies according to the thickness of the insulation board. They are widely used in the anchoring of wall insulation houses. They also have anti-aging, resistance to sudden temperature changes, corrosion resistance, high bearing capacity, good pressure and tensile properties, are not easily deformed after loading, are moisture-proof, shock-absorbent, and have good thermal insulation properties. They are easy to install and do not require special tools. The galvanized screws effectively solve the corrosion problem, have good durability, and the low thermal conductivity of nylon material ensures there are no cold bridges in winter, leading to high energy efficiency.
