The elastic gun foam for all-season use with high sound and heat insulation
1c premium flex foam PUP FLEX 750 B2
The elastic fischer 1c premium flex foam PUP FLEX 750 B2 is suitable for all- season insulation and filling of window connections, roller shutter boxes and window sills as well as elastic filling of connection joints and cavities in wooden structures and roof extensions, with its high sound and heat insulation. High elasticity enables the absorption of component movements and prevents the formation of cracks or thermal bridges. The product has a large processing range from -10°C to +35°C. An excellent dimensional stability avoids time-consuming and expensive reworking. The safety valve prevents adhesion. Safety gloves for end users are enclosed.
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.
