- How big is the area to be insulated?
- The nature of the insulation: each material is characterized by its insulating performance (whose thermal resistance is R). Depending on the desired efficiency and the R-value, you can define the thickness of insulation required for your trailer.

How to thermally insulate a caravan?
To thermally insulate a caravan you can use an asphalt blanket, aluminium adhesive felt, EVA thermal insulation or aluminized etalon. Coating the interior of the vehicle with these characteristics is what creates the insulating layer, helping to prevent heat from the exterior from reaching the interior of the vehicle.
How is the insulating membrane placed?
The role of insulation should be extended towards the highest part of the ceiling. Once the roll reaches the highest level of the ceiling, it must be attached to the structure. Once the insulation is fixed on the top of the roof, it should be aligned until it is parallel with the braces.
How do you insulate the underside of a static caravan?
Insulating the underside of a static caravan usually allows you to enjoy your mobile home during summer, autumn and spring. Still, insulating only the underside is rarely enough to keep warm in the caravan.
Should you waterproof a trailer roof?
Yes, you should consider waterproofing a trailer roof right after insulating it. The waterproofing process typically involves installing infill under your static to further reduce any form of air infiltration.
