The 210 × 210 mm overpressure grille from the quality brand Renson is made from AIMgSi 0.5 aluminium profile and finished in RAL9005 black, without insect mesh. The louvres are mechanically linked and open and close together to reduce noise. They sit within the aluminium frame, preventing wind from moving them when the louvres are closed (under normal weather conditions). The grille is supplied with screws and plugs and features concealed screw fixings. The build-up height is 29 mm.

We had a great experience with Monsif and his team. With the Duco Energy Premium WTW-all-in-one package we were given all the information we needed. They inspected our house and came with an complete tailored solution for our house. We now have a quiet and really affordable wtw installation.
Their service is terrible, they do not comply with the delivery time, their work is not organized, I was very dissatisfied and their prices are quite expensive, I do not recommend it
we hired Moncif (wtw.nl) to advise and install a Zenhder Q in our place. Very knowledgeable and carefull on the details. Took care of many details to guarantee the optimal flow and low noise. We had few issues with timelines but Mocif was aways available and went beyond to guarantee all is perfect and in place. Definitely recommend and thank you for the great service.
