The Roof-PIN type A is attached to the wooden support shell with 4 wood screws. The seal is made with a roof membrane, which is clamped between the lower part with thermocouple fixed on the supporting shell and the upper part. For this purpose, the roof membrane is only punctured minimally and the puncture point is also slightly elevated, which guarantees long-term impermeability.

The Roof-PIN type A is attached to the wooden support shell with 4 wood screws. The seal is made with a two-layer bitumen sheeting and a stainless steel sheet, which is clamped between the lower part with thermocouple and the upper part, which is fixed on the supporting shell. The prefabricated stainless steel sheet is only minimally pierced and pressed on, and the piercing point is also marginally elevated, which guarantees long-term tightness. The bitumen layers are glued over the entire surface up to the Roof-PIN.
