Our versatile thermal curtain linings can regulate room temperature throughout the year and also help reduce the amount of external light that enters your room. These linings can also be cut down to suit your requirements. Our ready made pencil pleat and eyelet lining kits are intentionally manufactured 3-4" shorter than your main curtains so that when they are hung at the reverse of your main curtains, the top of the lining hangs 2-3" below the top of the main curtain and the base hem sits approx. 1" above the main curtain base hem. This is so the lining remains hidden and does not hang below the bottom of your curtains.Professional cleaning in Hydrocarbon or equivalent recommended.
