ISO-BLOCO FILLER

Application

For sealing windows against masonry in cavity walls, both in new buildings and where windows are being refurbished. The insulation and sealing system is pressed directly into the opening between the inner and outer wall cavity before the window is fitted.

Description

A multi-functional insulation and sealing system which has been developed especially for window fitting in cavity walls. It is fitted in the gap between the inner wall and outer faced brickwork.


It is made up of two functional components: One of these is a filler block made of highly elastic special foam. This forms the basis for sealing the window against the building and seals the gap between the window and the cavity wall aperture. The high elasticity of the filler block guarantees a firm fit and makes the air tight closure of the masonry opening possible.


The second component of the sealing system is a sealing bar constructed from impregnated foam, which guarantees sealing of the window frame against the outer wall and protects the window connection joint securely against the influence of the weather in the rebate area.


Features and benefits:

  • Complies with DIN 18542 BG 1.
  • Simple fitting, conforming to window sealing standards in cavity walls.
  • Ideal for 'check reveal' situation.
  • High adaptation to 'check reveals' of up to 30%.
  • Integrated sealing tape system for sealing the weather protection level.
  • Flexible adaptation to unevenness of the inner wall.
  • Complies with EnEV requirements and the recommendations of the RAL 'Installation guide'.


Rebate suitability:

  • For joints up to: 6 mm.
  • For widths up to: 45 mm.
