PRODUCT DESCRIPTION
ISO-BLOCO RENO is a multifunctional sealing and insulating system specially developed for energy-related window renovation. It is made up of two connected sealing components. The core layer is made of high-quality polymeric material and provides a smooth surface for the seal. The excellent material component properties guarantee a tight fit in the U-recess which remains after the removal of the old window frame. At the same time as sealing the cavity in the masonry, it forms the basis for the upper sealing layer. The sealing layer is made of impregnated, pre-compressed PUR soft foam with an integrated airtight membrane. The multifuntional material has 3 distinct areas which combine to achieve the 3-level sealing required by the RAL “Installation Guide”. On the internal side it has an a-value of 0.00, which means it is 100 % airtight and acts as a vapour barrier, in the middle area it ensures optimum acoustic and thermal insulation and in the outer area it provides outstanding protection from the weather with a driving rain impermeability of more than 1,000 Pa (Hurricane Forces).

Applications
ISO-BLOCO RENO is excellent for standard-compliant sealing work done during window renovation/replacement. The sealing system is fitted directly into the U-recess left from the removal of the old window before the new window is installed. The fixing process is by means of flexible sealing flanks.
To make fitting easier, the tape has also been made self-adhesive. Where U-recesses are particularly deep, we recommend to first back-fill the recess with a suitable insulating material. In addition, ISO-BLOCO RENO is compatable with all know building insulating materials.
