As the weather starts to get colder, the best thermal curtains will help you keep your home warmer for longer.

While we’re all trying to save on skyrocketing energy bills, one simple and relatively affordable way to up the insulation in our homes is to invest in an effective pair of the best thermal curtains. A must for period property dwellers with original sash windows, or those with draughty French doors, these heavy drapes will see us through the winter. While some thermal curtains offer heat-retaining properties in the face material – a weighty velvet being a prime example – others boast a lightweight fabric teamed with a thermal lining that promises to keep the cold out.

To get the most out of your thermal curtains, it’s vital to measure up properly: you’ll need to ensure there’s no heat escaping from the top, bottom, or sides of your drapes, and that your window or door is fully covered. Allow for a few inches in the drop to give you complete coverage, be aware of the height you’ve got your curtain pole or tracking, and allow for this in your calculations. That said, most pencil pleat curtains come with a generously wide heading tape, which will give you some leeway. Of course, made-to-measure curtains are the way to go if you want the perfect coverage for your window, but the best ready-made drapes come in a huge range of sizes, including options for extra-wide bay windows, and even floor-to-ceiling double doors.

M & S Collection Velvet Pencil Pleat Ultra Thermal Curtains

Available in a choice of three colourways and five sizes, these richly textured velvet curtains are sufficiently heavyweight to keep the heat from escaping. And while they offer a classic, timeless look, they’re crafted using M&S’s innovative Temperature Smart technology.

John Lewis Rona Lined Eyelet Curtains

These eyelet-topped curtains marry contemporary shaping with a craft-driven aesthetic. The fabric boasts a textured woven pattern in a calming sea blue and cream colourway, while there’s little chance of heat loss, thanks to their weighty makeup. Choose from eight sizes.

So'home Thermal Interlined Ringlet Curtains

With their all-over repeat geometric patterning, these velour curtains catch the light beautifully. There’s a generous choice of six sizes, ensuring you get the best coverage for your window, while an added layer of material between the face fabric and the lining offers extra warmth.

Even with fully double-glazed windows and doors, heat will always find a way to escape our homes, and so proper insulation is a must. Thermal curtains can act as an effective barrier between our cosy living spaces and the outside air getting in. When properly fitted, these heavyweight drapes can reduce heat loss by as much as 25 per cent, which will, in turn, reduce our need to crank up the thermostat.

While thermal curtains are typically associated with a winter purchase, they can, in fact, have the opposite effect of keeping us cool in the summer months, blocking heat from entering the room – a godsend on particularly sticky nights. Thanks to their thickness and weight, many thermal curtains come with blackout properties, too, allowing little to no daylight to seep through the fabric. And they can even act to reduce noise.

Due to its tightly gathered design, a pencil pleat finish will ensure there’s minimum heat loss, especially if your drapes are attached to the wall via a curtain track. Eyelet tops, however, have a tendency to let air escape through the top of the curtains, due to their extra-wide pleats, so it’s important to ensure the whole window or door is fully covered. If you’re using a curtain pole, whether you plump for pencil pleat or eyelet, make sure its brackets don’t jut out too far from the wall, otherwise you could lose precious heat on all sides.

So'home Thermal Interlined Ringtop Curtains

In a choice of dark teal, blush, pale grey or ochre, these heat-retaining curtains add either a bold colour pop or a calming neutral to living spaces and bedrooms. Crafted from 100 per cent polyester, the velour curtains feature an embossed geometric repeat pattern that awards the drapes both an attractive visual texture and a luxurious feel. The curtains prove surprisingly lightweight despite their thermal properties, yet they more than do the job, keeping the room toasty warm and importantly, draught-free, and this is largely thanks to the curtains’ interlining, meaning an additional layer of fabric between the main material and the lining.

Julian Charles Luna Navy Blue Thermal Blackout Eyelet Curtains

This rich dark navy offering is one of our favourite colour choices, although it's also available in other finishes. With a blackout coating to save your eyes from pesky streetlamps, early morning sun, and more, it also acts as an excellent thermal insulator, keeping your room cooler in the summer and hotter in the winter. Its heavy weight also means it'll hang beautifully too. It can be washed as well, making for a rather practical yet elegant solution in bright rooms that need an extra bit of TLC to achieve maximum cosiness.

M & S Collection Velvet Pencil Pleat Ultra Thermal Curtains

There’s nothing like thick velvet drapes to add a touch of old Hollywood glamour to your living space. M&S’s offering boasts the brand’s Temperature Smart technology, which not only proves an effective insulator, but promises to keep the room cool in the summer months, too. The ready-made curtains come in a choice of three colourways; navy, grey, and ochre, and feature a distinctive geometric quilted border underneath the pencil pleat top, adding a luxurious textural element to the mix. The curtains are made from a rich polyester velvet and work wonders in keeping the cold out. Sufficiently weighty, they drape beautifully at the bottom and, we think, look even more opulent if hung a little long.

Habitat Plain Chenille Blackout Lined Thermal Curtain

A lighter weight and more affordable alternative to velvet is, of course, chenille, but these ready-made curtains are no less luxurious. The main fabric might be less than heavy but cleverly, the curtains boast a thermal blackout lining that successfully blocks any daylight whilst keeping the heat from escaping. Made from 100 per cent polyester, the curtains more than prove their heat-retaining credentials. Sturdy silver iron eyelets ensure a neat and symmetrical drape, while the soft chenille fabric offers a textural interest, both visually and to the touch. Choose from three simple colourways; a light grey, a mid-teal blue, or a rich wine red.

John Lewis Rona Pair Lined Eyelet Curtains

Crafted from a rich polycotton blend, and with an all-over textural geometric pattern in soft blue and cream, John Lewis’ Rona curtains are contemporary and homely in equal measure. The heavyweight fabric protects against heat loss, especially when combined with the substantial polyester lining, and yet the curtains also prove cool in warmer climes, giving you the best of both worlds – and without having to change up your window styling once the weather improves. The eyelet-topped drapes are made with ‘Better Cotton’, which comes from environmentally aware farmers who respect workers’ rights and well-being. Curtains with a conscience.
