About Thermal & Insulating Curtains
A window is the leakiest wall in the room, and fabric is the cheapest insulation you can hang on it. Thermal curtains work by trapping a still-air layer between the glass and the room: dense face fabrics, tight weaves, and insulating linings that measurably cut drafts in winter and solar heat gain in summer. The physics rewards fit — panels cut to your exact window, mounted wide and run floor-length, seal the air pocket that stock sizes leave open at every edge. Choose a heavyweight fabric below, add the lining that matches your climate, and we'll sew it to your measurements in our own workroom. Swatches first if you want to feel the weight; delivery runs 7–10 business days.
