Thermal Door Curtain

A single solid-color heat-insulation curtain for a doorway, based on the verified supplier listing. It is not a magnetic-split curtain, it does not have a fleece or coated thermal lining stated in the supplier specification, and it is not sold as a pair.

What you get
One curtain only (packing list: Curtain x 1). Material: polyester; fabric composition: polyester fiber (polyester). Process: printing. Style: modern and simple, solid color.

Function: high shading (70%-90%). That means it is listed for high shading and heat insulation / sunscreen use, not as a 100% total-blackout curtain. Do not expect it to block all light.

Sizes (all 134 cm wide, perforated / punching top)
A: 134 x 160 cm
B: 134 x 210 cm
C: 134 x 240 cm
D: 134 x 270 cm
The longest size, 270 cm, is the one that can cover a full standard door height with length to spare. Choose a length that reaches the floor without pooling heavily.

Supplier colors listed: navy blue, light blue, gray, coffee, beige, khaki.

Why a curtain over a doorway helps
Most UK homes lose heat through one or two bad doorways. Hallways are usually the coldest part of the house – they are rarely heated directly, and a front door often has a letterbox, a keyhole and a gap at the bottom, all leaking cold air in. That cold air pulls warm air out of a living room every time an internal door opens, and seeps under it the rest of the time. A curtain hung over the doorway adds a layer between the door and the room and, more importantly, stops moving air. Draughts are what make a room feel cold even when the thermostat says otherwise.

Measuring and fitting
UK internal doors are commonly 1981 mm tall, with widths of 686, 762 or 838 mm. Measure the full frame width, then allow 10-15 cm for side overlap, and measure from the top of the frame to the floor. The curtain should just kiss the floor, not pool. This curtain is 134 cm wide, so check that width against your frame plus overlap before ordering – one single panel will not cover a very wide or double doorway on its own.
The supplier lists the sizes as perforated / punching, so hang it from a suitable rod or pole through the punched top. The supplier specification does not state a magnetic split, hook-and-loop fixing, tension rod, or no-drill fitting, so this listing does not promise any of those. Keep fabric clear of radiators and any heat source, and never fit a curtain where it would slow down a fire-escape route.

What it will not do (honest downsides)
It will not fix a door with a broken seal or a big gap underneath – that is a draught-excluder job first, curtain second. It makes the doorway slightly slower to use, because this is a single panel to move aside, not a hands-free magnetic split that parts and snaps shut. It insulates one doorway, not a house. Expect the room to feel warmer and the hallway draught to be reduced – not a miracle on your total bill. Be suspicious of any seller promising a specific percentage off your bill; that depends entirely on your house. The supplier does not state washing instructions in the listing, so check the care label when it arrives rather than assuming a wash cycle.

FAQ
Do thermal door curtains actually work? For the job they are meant for – reducing draughts and heat loss through a single doorway – yes, when hung to cover the opening with overlap at the sides and at the floor. They work best on doors to unheated spaces – hallways, porches, cellars – where the temperature difference is biggest.
What size do I need? Bigger than the hole. Add 10-15 cm to the frame width for side overlap and choose a length that reaches the floor. Most UK internal doors are 1981 mm tall; a 210 cm curtain covers a standard frame, and the 270 cm size gives the most length for taller frames or a floor-length drop.
Will it help with noise and cooking smells? A little. A curtain hung over a doorway can muffle hallway noise and slow smells spreading from the kitchen. That is a side benefit, not a soundproofing product.
