1c maxi gun foam PUP S 500 B2

The proven sound and thermal insulation foam with higher foam yield for professionals in a short can

The fischer gun foam Standard Maxi PUP S 500 is suitable for the filling, insulation and isolation of window connection joints as well as window sill and shutter box joints. At 43 litres, the compact, handy foam can offer the same yield as the 750 ml can, and thanks to no premature gas loss, it allows for a high rate of emptying. The low foam expansion rate during the hardening process avoids time-consuming and costly rework. The fischer gun foam Standard Maxi PUP S 500 B2 meets the high requirements placed on sound and thermal insulation. The beige fischer PUP S 500 is fitted with an improved standard valve that extends the product's shelf life.

Product Description

  • The short, handy can allows the correct positioning in awkward places and leads without premature gas loss to a high emptying of residues.
  • The low level of foam expansion during the curing period avoids reworking, thus guaranteeing a simple and time-saving application.
  • The thermal protection and proven airtightness allows compliance with energy saving according to EnEV and substantiated as effective reduction of heat loss.
  • The high joint soundproofing of 61dB fulfils the standards of modern sound insulation and helps to reduce noise.
  • General test certificate from buildingh authorities P-NDS04-137 für B2
  • Proven joint soundproofing: R(ST,w)=61 (-1;-3) dB in line with ISO EN 717-1
  • Proven thermal conductivity: Reduces heat loss at 0.0345 W/(m * K)
  • Based on DIN 18542 proven airtightness of a<0,1 m³/[h*m*(daPa)²/3]
  • French VOC-emission class A+
  • EMICODE® EC 1 Plus - very low emission
