1c gun foam PUP S 750 B2

The one-component gun foam with proven joint sound-proofing, thermal insulation and water pressure resistance

The fischer gun foam Standard PUP S 750 B2 is suitable for the filling, insulation and isolation of window connection joints and for the filling of door frame connection joints. The gun foam has tested joint sound and thermal insulation as well as water pressure resistance, and only expands slightly during hardening. This avoids the need for rework, thus ensuring easy and time-saving application for professionals. The beige PUP S 750 B2 is fitted with an improved standard valve that extends the product's shelf life. Protective gloves for end users are included.

Product Description
