Froth-Pak insulation spray foam, 400 and 1400 litr

With the Froth-Pak sets, you produce PU foam of the highest quality easily and at lightning speed. The insulation foam solidifies in about 60 seconds and is fully cured after only 10 minutes. The cured foam has a very high insulation value and adds structural support to most substrates (including wood, metal and glass). In addition, Froth-Pak dampens noise, fills cavities and provides a perfect air seal.

User-friendly polyurethane

The sprayable polyurethane foam comes with 2 pressure tanks and is very user-friendly. After mounting a hose set, the set is ready for use. You do not need a compressor. The insulation foam can be dosed with the spray gun (included with the hose set) on, for example, walls, ceilings, roofs and in gaps.

Environmentally friendly PU foam 

To comply with the European regulation on fluorinated greenhouse gases, Dupont has updated the formulation of Froth-Pak. From July 2022, Froth-Pak PU foam contains the most environmentally friendly blowing agent. The formulation uses HFO instead of HFC. HFO has a very low global warming potential (GWP).

Benefits of Froth-Pak PU foam

• Very low global warming potential (GWP) due to HFO blowing agent.
• Fine-celled moisture-proof system.
• Very high insulation value (lambda value 0.021).
• Fast curing in approx. 10 minutes.
• No more condensation.
• Easy application.

Instructions for use

In the video below, Kees explains how to prepare the Froth-Pak for use. Make sure the cylinders have the right temperature of 24-30°C during use. If necessary, use our Froth-Pak heating jackets for this. Read the instructions carefully before use. 

Calculation examples

• With a 400 litre set, you can provide 13 m2 with a 3 cm thick layer or 4 m2 with a 10 cm thick layer.
• With a 1400 litre set, you can provide 45 m2 with a 3-cm-thick layer or 14 m2 with a 10-cm-thick layer.

These are examples. You can of course spray other thicknesses.
