Glass Wool

Glass Wool

Byucksan Glass Wool is the first to be produced by the rotary method in Korea. This glass wool has a smaller number of glass spines, thinner fibers, and higher fiber density, so it provides excellent effects in both thermal insulation and sound absorption.

Features

Thermal Insulation

This glass wool helps save heating and cooling costs substantially as it contains a large enough amount of air to produce a thermal insulation effect 40 times higher than concrete and 12 times higher than mud-plastered wall.

Sound Absorption and Elasticity

Its high sound absorbing effect makes the room more quiet and comfortable by blocking out noise from outside, and its strong elasticity protects the installation from any vibration or impact from outside.

Stability

It has a smaller number of glass spines, and its waterproof, flameproof, and noninflammable properties help to minimize the damage from a fire.

Cost Effectiveness

The use of compressed packaging makes it easy to store and carry the product; As a result, this helps save the installation cost by shortening the installation period.

Tensile Strength

Its high tensile strength ensures an excellent workability and self-support capability.
