1c premium gun foam PUP 750 B2

The one-component gun foam with proven sound and thermal insulation as well as increased foam yield

The fischer gun foam Premium PUP 750 B2 with sound and thermal insulation testing is particularly suitable for the filling, insulation and isolation of window connection joints and for the filling of door frame connection joints. The high yield of up to 55 litres reduces the number of cans needed, thus ensuring maximum economic efficiency. The low foam expansion rate during the hardening process avoids time-consuming and costly rework. The yellowish PUP 750 B2 has a solid valve that offers top security against blockages and the loss of gas. Protective gloves for end users are included.

Product Description

  • The thermal protection and proven reduction of air permeability fulfil the high standards for modern thermal protection.
  • The proven 61dB sound insulation fulfils the standards of modern sound insulation and helps to reduce noise.
  • The high yield of up to 55 l reduces the number of cans needed, thus ensuring maximum economic efficiency.
  • The low level of foam expansion during the curing period avoids reworking, thus guaranteeing a simple and time-saving application.
  • The new safety valve prevents adhesion when being stored horizontally or during long interruptions of work, thus guaranteeing long-lasting functionality.
  • General test certificate from building authorities P-NDS04-137
  • Proven joint soundproofing R(ST,w)=61 (-1;-3) dB in line with ISO EN 717-1
  • Proven thermal conductivity: Reduces heat loss by 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
