Twiga Insul for Thermal and Acoustic Insulation

Thermal Performance Thermal Conductivity in W/MK Acoustic Performance Fire Safety Advantages Applications

Cooling costs in a building insulated throughout with glass wool can be reduced significantly. The use of glass wool for the thermal insulation of external walls and ceilings has been shown to reduce energy consumption by 20% to 30%.

Twiga Glass Wool with its outstanding acoustic performance has excellent acoustic absorption characteristics. Whether it is sound insulation for industry, commercial premises, public buildings, or domestic applications, Twiga Insul outperforms others.

Acoustic Insulation values of:

Thickness (mm) Noise Reduction Coefficient Sound Absorption Class Test Standard
25 0.71 – 0.89 Class B ASTM C 423 / ISO 354
50 0.75 – 0.95 Class B – Class A
100 >0.85 Class B – Class A

Twiga Insul glasswool made from pure silica sand will not support combustion even in direct, prolonged contact with flames. It does not emit toxic fumes or smoke, which are the two biggest health hazards during fire. Glass wool is a complete fire safe product complying the following standards:
