Frequently Asked Questions
How much difference does it make on a hot afternoon?
It stops direct sun before it turns into heat inside the room. In a west facing room in July that is the difference between an unusable afternoon and somewhere you can sit and work.
Will it damage my window frame?
Nothing is drilled, screwed or permanently attached. It mounts with adhesive or tension depending on the opening and comes down again without leaving damage, which is why it suits renters.
Does it darken the room properly?
Yes, which makes it useful for shift workers sleeping in daylight, nurseries at bedtime and any bedroom facing a streetlight.
What size should I order?
Measure the opening and choose the size that covers the glass with a little margin each side. Coverage at the edges is where light and heat sneak back in.
How do I mount and clean it?
Clean the frame and let it dry fully first, since both adhesive and tension fittings hold better on a dry dust free surface. The panel itself wipes clean with a damp cloth.
