Top 10 Questions About Warm Window Insulated Shade Fabric
Q: What is Warm Window Insulated Shade Fabric made from?
A: Warm Window combines multiple layers — typically a soft fleece face fabric, an insulating middle layer, and a metalized reflective backing. The result is a fabric that provides genuine thermal insulation for window treatments while looking beautiful from the room side.
Q: How much energy can insulated Roman shades with Warm Window save?
A: The Warm Company reports that Warm Window shades can help reduce winter heat loss through windows by up to 50%. Windows are major sources of heat loss and gain — insulated treatments make a measurable difference in energy bills.
Q: What window treatment styles work best with Warm Window?
A: It is most commonly used for Roman shades, roller shades, and lined drapes. Its structured layers make it ideal for treatments that need to hold their shape and maintain flat panels rather than soft, gathered window fashions.
Q: Is Warm Window suitable for quilting projects beyond window treatments?
A: Yes — it is used for insulated pot holders, oven mitts, tote bags for hot or cold items, and any sewing project where thermal insulation and a professional layered structure are desired.
Q: How wide is the 54" bolt and what does that mean for window shade cutting?
A: At 54" wide, a single width of Warm Window covers windows up to approximately 48–50" wide (after seam allowances). For wider windows, two widths can be joined, or narrower shades can be cut side by side from a single width.
Q: Is Warm Window washable?
A: Finished projects made with Warm Window should be spot cleaned or dry cleaned to preserve the structure and insulating layers. Machine washing can disrupt the layered construction. Always follow The Warm Company's care recommendations for your specific project.
Q: How many Roman shades can I make from a 15-yard bolt?
A: Depending on window height and width, a 15-yard bolt typically provides enough Warm Window for 6–10 standard Roman shades, making it appropriate for a room set or a small production run for a design client.
Q: Does Warm Window block light as well as insulate?
A: The metalized backing provides some light-blocking properties, though it is not a true blackout fabric. For maximum light blocking combined with insulation, pair Warm Window with an additional blackout lining layer.
Q: Is the shiny (metalized) side of Warm Window facing the window or the room?
A: The metalized reflective side should face the window — it reflects heat back into the room in winter and reflects solar heat back out in summer. Always follow the pattern or construction instructions for your specific project.
Q: Is Warm Window difficult to sew on a standard sewing machine?
A: The multiple layers require a heavier needle (size 90/14 or 100/16) and a walking foot is highly recommended for even feeding. Sewing through the layers is manageable on most domestic machines with the right setup.
