Thermal Blinds

Thermal blinds, also known as insulated blinds, reflect light and heat and are an increasingly popular option for many homeowners. Not only can they make your home look super stylish, they’ll prevent you from cranking up the heating in the winter months and save you money on your energy bills. Whether you want thermal roller blinds, thermal roman blinds or thermal blackout blinds, we have a wide range of styles and designs available at Dunelm. 

Thermal Conservatory Blinds

As much as a conservatory can be a wonderful addition to your home, anyone who owns one will likely understand the constant battle that is temperature control. In the summer months, they can become uncomfortably hot and stuffy. Conversely, in the winter, heat can escape from your conservatory far too easily. In this respect, thermal conservatory blinds are an excellent choice. Not only can they prevent heat loss, keeping you snug and warm when it’s cold outside, but they also reflect heat from the sun too. So, why not do away with complaints from the kids about the conservatory being too hot and ensure your family has a nice, cool space to retreat to this summer?

We’re confident you’ll find the best thermal blinds for your home at Dunelm. Be it for your bedroom, kitchen or conservatory, we have a variety of stylish designs that will fit seamlessly into your home. Remember, if you don’t find the size you need, check out our made to measure service for tailor made thermal blinds. We take you through the whole process from measurement to fitting.

What are thermal blinds?

Let’s start by clarifying what a ‘Thermal Blind’ is, for us, it’s a blind that is specifically designed to help either trap heat in your room, preventing it from escaping, or to help keep your home cooler in the winter by reflecting sunlight away from your window.

Good news is that our thermal blinds do both.

Bad news is that there are only a few options to choose from.

Do thermal blinds work?

By the very nature of putting another layer of something in your window between your room and the window pane, you’ll help to reduce the amount of heat lost through convection and also lost through conduction.  Thermal blinds will help to keep heat in during the winter and help to keep your home cooler during the summer, but don’t expect them to replace or be as good as air-con.

Thermal blinds are only really suited to certain rooms too, sure, you can install them where you want, but we find that the majority are in bedrooms for the winter months. Nothing beats a nice cosy bedroom in the depths of winter. We have a couple of Thermal blind ranges, one is our Roman blinds with a thermal lining which is thicker fabric backing helping to trap heat in. We also have our cellular/honeycomb blinds for a conservatory window. These clip into the frame between the glass and rubber beading and their structure means they help to trap a layer of air helping to prevent heat loss. Their unique structure means that when raised up in the window they hide almost completely from view, and if you choose the blinds with the blackout option, you’ll be able to shade your room from the light and give yourself full privacy in your home. With the Roman blinds thermal lining, it’s not a blackout, but verging on it, so is still good for bedrooms but just to warn you it won’t block 100% of the light.

What are the Best thermal blinds?

This is a tricky one, as previously discussed we have 2 main types of ‘Thermal Blind’ 1 being the thermal lined Roman Blinds, and the 2nd being the Cellular (pleated) conservatory blinds. The cellular ones work best in conservatories and UPVC windows – so things like patio doors and French doors. But these wouldn’t look so good on your bedroom window. So instead we would opt for our Thermal lined Roman blinds as these will do a good job of helping to keep your room warm/cool, but will also look pretty snazzy in your window. We’re not saying don’t use cellular blinds in your bedroom, but more from an interior design point of view, Romans are better.

If you’re not a fan of either type then we would suggest a thicker blackout roller blind fabric that overlaps the entire window recess, helping to reduce draughts as much as possible, or choose curtains or shutters for a better coverage.

What are Cellular blinds?

This is the name given to blinds, generally conservatory pleated ones, that contain a honeycomb shape within them. This helps to create lots of little pockets of air, keeping convection to a minimum (like double glazing) and also help to reduce the amount of heat lost or gained through conduction. These blinds can come in a few types, there is a dimout version that will help to let light into your room, but will also act as a thermal barrier. We also have a range with a reflective backing that helps to reduce heat gained through thermal radiation and reflect the sunlight away – ideal for hot summer days. These are perfect for a conservatory as they can help to extend the usability period of your conservatory further into the winter. 

Are all blinds thermal?

We would say yes, but only in the context that by putting anything between your room and the window pane will help to create a barrier and help slow down heat loss in the winter. At the same time in the summer, anything white in the window will help to reflect sunlight away from the window, absorbing less heat and keeping your room slightly cooler. But, not all blinds are equal in their thermal property. For example, our Voile roller blinds would frankly be pretty useless at trapping heat in because they are designed to let the light in during the day, whilst still offering privacy. But our Skylight blinds, whilst not thermal are a thicker material that is blackout and when closed will help to prevent heat loss through the glass.

Technical Disclaimer – When we talk about heat loss we use the term to relate to heat loss through conduction being reduced and by also helping to reduce draughts and therefore heat loss through convection in your home. When we talk about white backings to blinds reflecting/not absorbing heat this is a reduction in thermal radiation.

Made to Measure Thermal Energy Saving Blinds

Our extensive range of high quality thermal window blinds allow you to save money whilst bringing style and elegance to the windows of your home. With a choice of roller, roman, vertical, blackout, wooden and venetian blinds, all of our blinds have thermally efficient ranges that will reduce heat loss from the windows during the winter and conversely keep the room cool during the summer months.

From plain to patterned, textured to soft fabric designs, we have some gorgeous made to measure thermal blinds to compliment the décor of any bedroom, bathroom, kitchen, living room or dining room. They are the perfect solution if you are looking to reduce your energy bills. They are not only energy saving but a beautiful way to dress the windows of your home.

How do thermal blinds work?
They work by providing insulation and a thermal barrier at the window. They provide heat loss reduction in winter by reflecting heat back into the room and in the summer they reduce heat and light transmittance by reflecting solar heat and light out of the room.

How much can I save?
Depending on the style of blinds you choose, you can expect potential energy savings of up to 15% per year, which for an average sized three bed home could equate to a £133 annual saving.

In addition to reduced heating costs, you’ll also have a more comfortable home along with a smaller carbon footprint, and by using less fuel you produce less carbon dioxide which leads to global warming.

All of our energy saving window blinds are manufactured to the highest standards, using only the finest British sourced components. They come with a three year guarantee, child safety features fitted and with our free sample service you can find the perfect match for your room’s colour scheme.
