ISO-Chemie has addressed one of the main challenges faced in wintery environments with a new sealing solution.

The new ISO BLOCO 600 Premium Edition foam tape allows for faster and easier joint sealing in temperatures as low as - 30°C.

The pre-compressed impregnated self-adhesive foam tape, which has been independently tested and is BBA approved, can be used on joints up to 42 mm, providing a high-performance weather tightness and thermal/acoustic insulation seal for fenestration and façade applications.


The versatile ISO BLOCO 600 Premium Edition can be used to provide effective gap seals to accommodate expansion and movement while remaining permeable to trapped water and water vapour in extreme weather conditions - similar to a flexible breathable style material for the building facade.

Quick and easy-to-apply, the tape can be used to seal joints providing excellent thermal and acoustic insulation properties. It can accommodate a temperature range of -30° to +90° and is impermeable to driving rain with a minimum of 600 Pa, making it one of the best performing tapes in its class.

Once installed, a building is better protected from elemental factors like wind, dust and moisture ingress by accommodating the changes in structural movement caused by environmental, cyclical and settlement factors.
