Our Blog - Ideas and Inspiration for Blinds & Shutters

With another heatwave on the way, many homes across Bolton, Horwich, Westhoughton and the surrounding areas will struggle with rising indoor temperatures. British homes are built to retain heat — not release it — which means rooms can quickly become uncomfortable when the sun is beating through the windows.

The good news is that the right blinds and shutters can make a big difference. They’re one of the simplest, most effective ways to keep your home cooler without relying on fans or air conditioning.

When sunlight hits your window glass, it immediately begins to warm up. That heat then radiates into the room, raising the temperature throughout the day. This is known as solar gain, and it’s the number one cause of overheating in UK homes.

Blinds and shutters work by blocking, reflecting, and slowing down that heat before it spreads through your home.

1. They Reduce Solar Gain

Thermal blinds and shutters stop intense sunlight from hitting the glass directly. This prevents the glass from heating up and stops that warmth from radiating into the room.

2. They Create an Insulating Air Barrier

When blinds or shutters are closed, they trap a layer of still air at the window. This slows down heat transfer and helps keep indoor temperatures more stable.

3. They Reflect Heat Back Out

Light‑coloured or reflective blinds bounce sunlight away from the window, reducing the amount of heat entering the home.

4. They Allow Controlled Ventilation

Plantation shutters are especially effective because you can angle the louvres. Tilt them upwards to reflect sunlight away while still allowing airflow.

5. They Work Even Better When Used Strategically

Close blinds and shutters during the hottest part of the day, then open them at night to release trapped heat and cool the home naturally.

Studies from the British Blind & Shutter Association (BBSA) and UK universities have shown:

• Well‑fitted shading can reduce heat transfer by up to a third.

• External shading is the most effective, but internal blinds and shutters still make a significant difference.

• Homes with proper shading experience less overheating and maintain more comfortable temperatures during heatwaves.

Even though many studies focus on winter heat loss, the same insulating principles apply in reverse — slowing heat entering the home.

Here are some of the most effective options we supply and install across Bolton:

• Thermal or blackout roller blinds – excellent for blocking sunlight and reducing solar gain.

• Cellular blinds – trap air inside their structure, improving insulation.

• Shutters – offer adjustable light control and a strong insulating barrier.

• Perfect Fit blinds – reduce gaps around the edges, improving thermal performance.

If you’re unsure which option is best for your home, our team can help you choose the perfect solution based on your window type, room layout and how your home faces the sun.

To get the most out of your blinds and shutters:

• Keep them closed on sun‑facing windows from morning until late afternoon.

• Angle shutter louvres upwards to reflect sunlight away.

• Use light‑coloured blinds for better heat reflection.

• Open windows and shading at night to let cooler air in.

• Consider external shading for south‑ and west‑facing windows.

Blinds and shutters aren’t just about style — they’re a practical way to keep your home cooler, more comfortable, and more energy‑efficient during hot spells. With temperatures rising across Bolton, now is the perfect time to upgrade your shading and enjoy a cooler home this summer.
