ISO-BLOCO One Control is a pre-compressed multifunctional joint sealing tape packed in a tear-off activation film. Designed for sealing windows in accordance with Energy Saving Standards and RAL requirements. It was developed especially to allow simple and reliable pre-fitting. The tear-off cover ensures that the window sealing tape remains compressed, even when the roll is unwound.

ISO-BLOCO One Control now makes it possible to pre-fit a 3-level seal in the workshop. The easy-to-use pre-fitted tape packaged in a robust film combines three functional areas based on the RAL 3-level principle. The 1000 Pa outer area offers particularly high resistance to driving rain, while the middle area provides reliable thermal and acoustic insulation. The inner area with an a-rating of 0.00 guarantees a 100 % airtight seal.
 
ISO-BLOCO One Control thus helps to minimise heat losses due to convection as described in the current Energy Saving Standards. It also has an optimum vapour diffusion gradient from inside to outside (50 : 1) creating effective moisture transport to the outside and thus rapid drying of the joint.

 
■  The strip is activated exactly when required for controlled expansion
■  Cost advantage and time saving due to straight-forward prefitting off site
■  Can be fitted regardless of the temperature or weather conditions and no need for external access
■  3-level seal with just one product and in a single operation
■  Extended joint application range makes it even more versatile
■  A wide range of joints can be sealed with just a few strip dimensions
■  Resistant to driving rain to a minimum of 1000 Pa
■  High sd-value gradient, optimum moisture movement to the outside
■  Internal air tightness minimises heat losses due to convection
■  Suitable for passive house construction
■  Conforms to the requirements of Energy Saving Standards and the principles of the RAL assembly guideline

Accessories
 
■  ISO-TOOL Clip for quick and easy pre-fitting on PVC and aluminium windows frames
■  ISO-TOOL Cut special blade for creating reliable corners

The tape is usually fixed to the PVC or aluminium windows frames using a clip fixing. The ISO-TOOL Clip assembly tool is used to clip the ISO-BLOCO One Control sealing system safely into the grooves in the window profiles, and mechanically fix it to the window frame. The ISO-TOOL Cut corner tool ensures that the corner loops are shaped reliably. The pre-fitted tape is also available with one or two high-quality self-adhesive butyl fixing strips for use with wooden windows and on narrow protiles under 65 mm deep.
 
After the window is aligned and fixed in the appeture, the seal is activated by pulling the activation tab which tears open the foil perforations. This allows the seal to expand, reliably filling the joint within the recommended joint application area.
