Trailer roof insulaiton foam board vs reflectix.

Foam board is very popular for diy van insulation. With the same r value as that of the rigid foam spray foam is best for those who avoid extreme temperatures with lightweight rvs. 03 13 2014 05 27 pm akrvbob wrote. Air space equals r value if you don t provide air space this product provides almost no insulating value.

Foam board for campervan insulation. Reflectix s stated r 14 r values for exterior walls are good only if the reflectix is paired up with r 13 fiberglass batt insulation. Glued directly to the wall you are throwing your money away and polyiso from home depot would be much better. Reflective insulation products like reflectix might be one of the best inventions for life on the road.

Use aluminum tape in between the sheets of foam insulation and then use a spray foam to fill in larger gaps as needed. You get bonus points if the trailer insulation is produced in an environmentally friendly way. You may have small gaps in between the foam and the trailer frame boards. It s relatively inexpensive for the r value and comes in a variety of thicknesses and material compositions.

Bob please do not view refelctix as insulation. You don t want harmful gases or microscopic particles filling your living space. Not only can this material be used in various camping capacities but it s affordable and can be easily replaced if necessary. It does nothing to prevent convection or conduction transfer.

This low cost insulation method is simple enough for a novice to use the applicator and spray directly onto the walls of the rv. Reflectix prevents the transfer of heat by radiation by reflecting the radiant energy like a mirror but has no real insulation value aka r value. With styrofoam insulation you have no expansion of the material as you do with fiberglass. Without an air space refectix has very little value as insulation.

Either the material is impervious to moisture like rigid foam board or spray foam or has moisture control properties and natural mold resistance. Plain foam board will have an r value and will prevent convection and conduction but cannot reflect radiant heat.
