Key Features & Properties
Waterproof, not hygroscopic, and non-capillary.
Non-combustible classification Category A.
Outstanding dimensional stability under thermal exposure and humidity.
Highly durable: will not fall off, decay, mold, corrode, or oxidize over time.
Resistant to bugs, insects, and microorganisms.
Easily installed and transported around sites due to lightweight packaging.
Environmentally friendly: made from up to 65% recycled content with biosoluble formulation.
Reduces overall building energy usage while offering custom-cut lengths to minimize installation waste.
Acts as a highly effective sound and thermal isolator with vibration-conserving features.
Aluminum foil coating provides maximum vapor permeability resistance, ideal for cooling systems to prevent insulation corruption.
Typical Applications
- Behind radiators (decreases heat loss by heat transmission)
- Thermal and sound insulation in sides
- Interior thermal and sound insulation of wooden houses
- Exterior insulation of HVAC pipes and rectangular or square cut ventilation pipes
- On the walls of boiler rooms and generator rooms
- Elevator engine rooms, stairs rooms
Frequently Asked Questions (FAQ)
1. What are the standard dimensions of the Glass Wool Insulation Board?
The standard length ranges from 1200mm to 2400mm, the width is between 600mm and 1200mm, and the thickness ranges from 20mm to 100mm. Custom dimensions are also cut to reduce onsite installation waste.
2. How does the glass wool insulation board react to fire?
The insulation board is rated with an A1 reaction to fire classification under the EN13501-1:2007 standard, meaning it is non-combustible and provides superior thermal security.
3. Does this material absorb water or moisture?
No. The glass wool insulation board features excellent hydrophobicity of greater than 98.2% and a water content of less than 1%. It is designed to be neither hygroscopic nor capillary.
4. What makes the aluminum foil coating option important for cooling systems?
The aluminum foil coating offers the highest resistance to vapor permeability. This plays a crucial role in cooling systems by preventing the risk of insulation corruption and damage caused by moisture and condensation over time.
5. Where can this glass wool insulation board be applied?
It is widely used behind radiators to reduce heat loss, for thermal and sound insulation in walls, in wooden houses, on exterior HVAC and ventilation pipes, boiler/generator rooms, and elevator engine rooms.
