PUP FLEX 750 B2 (EN)

The elastic gun foam for all-season use with high sound and heat insulation

Art.-No. 543451

Product Description

  • The high elasticity enables the absorption of component movements. This permanently prevents the formation of cracks and thermal bridges and maintains the airtightness.
  • The excellent dimensional stability of < 5% guarantees reliable operation under the temperature and humidity conditions that occur. This avoids time-consuming reworking.
  • Thanks to its winter suitability, the large processing range from -10°C to +35°C enables reliable processing even at minus temperatures. These important requirements are combined in one product.
  • The high joint sound insulation of 62 dB meets the standards of modern sound insulation and significantly reduces noise pollution.

Application and Permission

  • For elastic insulation and filling of window connections, roller shutter boxes, window sills and external doors
  • For elastic insulation and filling of areas with higher component movement due to thermal or static loads, e.g. in the old-building renovation, in steel construction, in timber-frame construction
  • Permanent, elastic foaming of connection joints and cavities in wooden structures and roof extensions, e.g. connection joints on roof windows, dormers, gables, rafters, purlins, eave
  • Permanently elastic filling of pipe penetrations, wall penetrations, wall connections and cavities
