The Fischer Pistol Foam Standard MaxiPUP 500 is suitable for filling, insulating, and sealing window connection joints, joints around window sills, and roller shutter boxes. The compact, handy foam can provides the same yield of 43 liters as the 750 ml can and allows for a high residual emptying without premature gas loss. The low foam expansion during curing avoids time-consuming and costly rework. The Fischer Pistol Foam Standard MaxiPUP 500 B2 meets high standards for sound and thermal insulation. The beige Fischer PUP 500 is equipped with an improved standard valve that extends its durability. It is intended for commercial users only and should be used without protective gloves.
