Tedeschi Gomma’s baz fixings have the function to fastening roofing, either in aluminium or in fibro- cement, by means of a screw which presses on a stainless steel washer.
The part in rubber, in addition to avoid infiltration of water, it compensate for thermal expansion of the aluminum as a result of changes in the weather. On fibro-cement coverings, it performs a compensating function due to hygroscopic material which varies in volume depending on the percentage of moisture in the air.
To ensure the best functionality, but not to mention above all the duration of time for this fastening system, it is necessary to use rubber EPDM of very high quality. The Baz Fixings from Tedeschi Gomma have this essential feature.
On customer’s request all of our products can be produced with compounds different than those mentioned.
