Does it really block heat from the sun?

The mirrored foil faces reflect radiant heat, and the maker claims 97 percent rejection. It cuts solar gain through glass well, but it does not stop heat conducted through the frame or wall.

How do I attach it to a window or door?

It comes with pre-cut self-adhesive pads. You stick the pads to the frame or glass and press the roll onto them. For a tighter seal, tape the edges.

Can I cut it to fit odd window sizes?

Yes. The foam core is thin enough to trim with everyday scissors, so non-standard RV and door frames are not a problem.

Will it stop drafts as well as heat?

It blocks wind whistles and cold gusts around gaps, but it is a 3mm foam layer. For serious air sealing, pair it with weatherstripping or caulk.

Is it safe to leave on glass in direct sun?

Reflective film on sealed double-pane glass can trap heat and stress the seal. On single-pane RV windows it is generally fine; check the glass maker's guidance for double glazing.

Yes. The smooth top layer wipes clean with mild soap and a rag without losing grip or fading.
