Power-teK® GB 220 ALU is a lightweight Glass Mineral Wool board, bonded on one side to a tear-resistant, glass mesh reinforced aluminium foil.

With thicknesses up to 300 mm per layer, this mat delivers a cost effective solution using a minimized number of layers. It is used for insulation of heat storage tanks and other tank walls with a service temperature up to 220°C, requiring strong thermal performance  throughout thicker layers of insulation. It is usually used outdoors underneath additional cladding (ALU-facing provides additional weather protection during installation, minimizing the possibility of defects and enabling high-quality, long-term insulation performance).

APPLICATION
The product is recommended for thermal and sound insulation of heat storage tanks and other tank walls where: 

• a lightweight insulation solution is required
• reliable heat loss reduction is required 
• fast installation due to reduced layers of insulation material is required
• rain-protected
