External wall insulation – features & benefits

Bostik has experience in successfully developing and launching external wall insulation systems in a number of markets, including the Republic of Ireland and Turkey.

Flexibility in sourcing components

Bostik provides customers with access to a controlled but enhanced supplier base for non-adhesive/render based materials, encompassing all suppliers and manufacturers who meet our performance requirements. This ensures the Climatherm external wall insulation system is one of the most competitive on the market.

Price transparency

By offering an external wall insulation system through distribution channels, we provide our customers with a system where the pricing is completely transparent. All components are individually priced unlike many other systems on the market.

Mature relationships

Our long standing working relationships with merchant customers are based on product quality and consistency of supply, as well as branch support which includes provision of advertising and promotional material.

System robustness

With the Climatherm system, insulation boards are adhered and mechanically fixed to walls. The use of adhesive offers three important benefits:

  1. To provide additional support between the wall and insulation board
  2. To prevent airflow up the back of the board, which can otherwise reduce the effectiveness of the insulation
  3. To act as a leveller

Range of high quality finishes

This includes Brick Effect Render, an attractive finish that mimics real brickwork and offers vastly improved speed of construction over brick slip systems.

Conformance with the latest European Standards

The Climatherm external wall insulation system has been tested under European Technical Approval Guidelines (ETAG 004) which sets out the performance requirements of external thermal insulation composite systems to demonstrate ‘Fitness for Purpose’. Many other systems currently on the market are only tested under older, less stringent UK standards.
