Method · Insulation
Liquid polyurethane is sprayed on, foams and sets into closed-cell insulation that fills every gap — under metal roofs and on walls with complex shapes.
Polyurethane sprayed as a liquid that foams up and sets into closed-cell insulation, filling every gap.
Undersides of metal roofs and walls with irregular shapes.
Exposed foam gets a UV-protective top coat.
Layers (built up from the bottom)
The metal sheet that covers the roof.
Sprayed under the roof, it expands into an insulating layer that keeps heat out.
The figure shows one typical build-up. The actual layers are decided after we see the site.
Insulation is chosen by the roof or wall and what it must do. If another one fits better, we will say so.
| Insulation | What it does |
|---|---|
| Heat-Reflective Coating | Light-coloured coating that reflects sun off metal roofs — factory roofs |
| Spray (PU Foam)this page | Sprays into every gap, seals cavities — roof, wall |
| Rigid Board (EPS/XPS/PIR) | Boards — compare below |
| Fibrous Wool (Rockwool/Glass) | Heat & sound wool, fire resistant — DC, walls |
The area, the insulation thickness the building needs, the shape and height of the roof or wall, and whether the foam is exposed and needs a top coat. Send the area and photos on LINE.
Spray foam fills every gap and seals cavities, so it suits metal roofs and complex shapes. Boards (EPS, XPS, PIR) are laid as panels and chosen by insulation, water and load resistance, and price.
Where it is exposed, it is finished with a UV-protective top coat.
Send the roof or wall area, what it is made of and a few photos. We check the site and propose the insulation that fits.
