High energy bills? Time to do something about it! Of course, there are many steps you can take to make your home more energy-friendly. In many old houses or old barns, the sloping roof is often poorly insulated. With sprayable PU foam, you can insulate your roof safely and quickly. In this guide, we explain step by step what you need to do.
It is best to calculate the number of litres. So suppose the total area of the roof is 10 square metres and you want to insulate 5 cm thick, you will need a total of 500 litres.
Follow the following 5 steps to insulate a roof with PU foam from Froth-Pak.
For high foam efficiency and fast curing, it is very important that the Froth-Pak is properly preheated and stays at the right temperature during spraying. This is easy to do with a heating mat. For a 400L set, 1 heating mat is sufficient. For the large 1400L set, you will need 2 mats.
Make sure the surface you are going to spray on is clean, dry and free of grease.
We will now prepare the Froth-Pak set for use. Do this in a number of steps:
First apply a thin adhesive layer with a blue nozzle. The blue nozzle is made so that the amount you apply is limited. This is ideal for a thin layer. We apply a thin layer first because a thick layer adheres better to existing PUR.
While spraying, make a smooth swinging motion from left to right.
When the entire roof has a thin layer, you can apply a thicker layer. To do this, connect the white nozzle supplied with the hose set. Spray a layer about 5 cm thick. This can be done in several passes if necessary.
