Buying Guide

Check thermal and blackout construction

Choose panels labeled thermal-insulated or 100% blackout—these multilayer fabrics reduce radiant and conductive heat loss

Match panel size to window dimensions

Use 37x50 panels only for similarly sized windows or stack multiple panels to ensure full overlap and minimal drafts

Prioritize noise reduction for added comfort

Noise-reducing fabrics often indicate heavier, denser weaves that also improve insulating performance

Consider color and light control

Darker or silver-backed panels like silver grey or navy increase thermal reflection; beige or aqua offer balance between light and insulation
