Firstly, what are thermal lined curtains?

Thermal curtains come in a variety of styles, colours, and fabrics but are normally made of cotton, velvet, polyester, silk, or microfibre. The difference between thermal curtains and blackout curtains is that they contain a layer of acrylic foam in between the layers of fabric that provide insulation. While blackout curtains have insulating and blackout features, the key benefit of thermal curtains is that they insulate the room by providing heat insulation and also blocking out sunlight and dampening sounds.

So, what about heat insulation in the summer?

A high quality thermal lined curtain will provide a barrier between a room and its window which will reduce any loss of heat. In the winter, this will keep the room warm and in the summer they can be used to block out the sun and keep the room cool.

Do they need to be cared for or maintained differently?

Maintaining your thermally insulated curtains differs depending on the style and fabric, it can be as simple as putting them in the washing machine or taking them to a dry cleaner. Maintenance instructions should be provided by the manufacturer, so if in doubt, always ask! For ongoing maintenance to keep them in the best condition possible, ensure that you regularly open the curtains to reduce any build up of moisture and eliminate the risk of mildew. Another top tip for thermal curtain maintenance is to spray the curtains with upholstery cleaner and use a vacuum to remove any excess – but double check with the manufacturer first as this is dependent on the fabric they are made from.

Finally, what are the benefits?

There is between 10-25% of thermal energy lost through your windows, thermal curtains reduce this amount of heat transfer by 25%. This helps keep your rooms cooler in the summer and warmer in the winter while also reducing your energy bills.

Another benefit is that the reduction in melatonin-inhibiting bright light is reduced, which will reduce any disturbance to your sleep. This coupled with the reduction in noise pollution are fantastic benefits for anyone who suffers from disturbed sleep, insomnia or for anyone who has irregular sleep patterns.
