Sandwich plates

Sandwich plates were developed as an accessory for the ISO-KASTL case. Their combination creates a well-insulated space around the window, ready-made for the easy installation of the external blind. The sandwich plate is fitted with an aluminium profile intended for subsequent installation of the embedded external blind profile.

Advantages of sandwich plates:

  • Excellent heat insulation
    • Very good adhesion to building materials
    • 100% waterproof
    • Supplied as ready-made, cut-to-size plates
    • Optional position of the guide rail in the plate
    • Easy handling due to low weight
