Reflictix Window and Vent Covers

These are to keep cold air out and warm air in. They will also keep hot air out, but we seldom use them for that purpose. We move instead.

Reflictix is bubble wrap sandwiched between reflective foil.

Lowe's sells rolls of Reflectix.

Add about a quarter inch to each dimension, as the Reflectix tends to "shrink" some with UV exposure over time. Plus the extra material will keep them in place.

For cab windows, I made paper patterns.  I sprayed white paint on the outside and beige on the inside to match the rig colors.

For extra warmth, put the LD foam cover on.

For the vents and skylight, just measure, add a 1/4 inch and cut.

Hint for fan vent, cut a slit for the open/close knob. For the other 14x14 vents, cut a slit for up/down handle. For the escape vent, I made them in two pieces with slits in both for the up/down handle.

We keep them in the windows in the upper bunk all the time, as we do not use that bed for sleeping.

We find the combination of the Reflictix and foam covers really helps about 8,000 feet or when the outside temp drops below 40.
