I am sure many of you have come across ventilation grilles that have been fitted to your roof by roofers and in the course of using the building this has come loose so it has become a gateway for rodents, martens and weasels. This fact should not be underestimated and the solution is to exclude the use of PVC grilles and replace them with aluminium ones with square perforations. Their main advantage is that rodents will not bite through them and, thanks to the square perforations, they ensure maximum ventilation area of the roof structure. Another reason to opt for these grilles is their aesthetic effect. They do not ripple on the roof at all and do not cause any disturbance.

The advantage of the 60 m roll in a box is transport and storage, but especially no need to rewire the grid. Let us advise you.
