Quick answer: Both shutters and blinds can keep your home cooler in summer — but performance depends on style, fit, material, and timing. Shutters offer superior insulation and a sealed barrier against heat. Blinds are more flexible and budget-friendly, with solar reflective rollers and tilted Venetians among the top performers for reducing solar heat gain.
There’s a particular brand of cruelty to a British summer. You’ve waited months for a bit of warmth, and then — the one week it actually delivers — your bedroom becomes uninhabitable by 3pm. Suddenly, the ceiling fan you bought in 2019 is doing its best, the ice lolly situation is critical, and someone’s Googling “how to keep cool at night UK.”
Sound familiar?
The good news: the right window coverings can make a real difference to how hot your home gets. Here at Jacksons Blinds, we fit both blinds and shutters across Newcastle and the wider North East, so we’ve got a pretty honest, practical take on which works best — and when.
Let’s get into it.
How heat actually gets in through your windows
Before comparing options, it helps to understand what you’re up against. When sunlight hits your windows, it carries solar energy that passes straight through the glass and gets trapped inside. This is the same greenhouse effect you feel in a conservatory that’s been baking all afternoon — and once that heat’s in, it’s hard to shift.
South- and west-facing rooms get the worst of it. South-facing windows receive strong, direct sunshine throughout the day; west-facing rooms cop the intense late-afternoon and evening sun — often just when you’re trying to unwind.
The goal isn’t to block all light (nobody wants to live in a cave). It’s to intercept that solar energy before it heats up the room, while still managing daylight and airflow. That’s where blinds and shutters come in.
One thing that matters more than most people realise: fit and coverage. Gaps around the edges of a blind let heat leak through. A blind that’s almost the right size is a lot less effective than one that’s made to measure.
The quick answer: shutters vs blinds for cooling
Shutters create a solid, close-fitting barrier across your window. When the louvres are angled or the panels are closed, they significantly reduce the amount of solar heat entering the room — and they do it with a clean, permanent look that doesn’t date.
Blinds are a broader category, and performance varies a lot depending on the type. A well-chosen roller blind with a solar reflective fabric, or a wood Venetian with the slats tilted just right, can be remarkably effective. They’re also more flexible — easier to swap out, available in a wider range of price points, and better suited to some window shapes and room types.
Best for at-a-glance:
- Bedrooms: shutters or blackout/thermal roller blinds
- Bay windows: shutters or bespoke made-to-measure blinds
- Patio doors and large glazed areas: vertical blinds, perfect fit blinds, or shutters
- Living rooms: Venetian or vision blinds for flexible light control
- Conservatories: perfect fit or shutters for a neat finish
Shutters to keep your home cool
Plantation shutters work well for summer cooling because of two things: solid coverage and adjustable louvres. The panels sit close to the window frame, reducing the amount of solar energy that slips into the room. The louvres let you fine-tune how much light comes in — and crucially, in which direction.
A practical tip: angle the louvres so they bounce light upward toward the ceiling rather than directing it straight into the room. You get brightness without the heat hitting your furniture (and your face).
Light-coloured shutters — particularly white or off-white — reflect more solar energy than darker finishes, making them especially effective on south-facing windows.
Best shutter styles for summer cooling:
- Full-height shutters — maximum coverage from top to bottom; ideal for south-facing rooms
- Café-style shutters — cover the lower half of the window, keeping privacy while letting cooler air and diffused light in from the top
- Tier-on-tier shutters — two independent panels; open the top for light and close the bottom for privacy
Worth knowing: shutters are a higher upfront investment than most blinds, and they’re not something you’ll swap out seasonally. But they’re built to last, they add value to your home, and they work just as effectively in winter — helping keep warmth in rather than out.

Blinds to keep your home cool
The word “blinds” covers a lot of ground. Here’s how the main types stack up for cooling:
Roller blinds — Clean, practical, and effective when paired with the right fabric. Solar reflective or thermal-backed fabrics bounce heat back through the glass before it enters the room. Lighter colours perform better than dark ones.
Venetian blinds (wood and faux wood) — One of the most versatile options for managing heat and glare. Tilt the slats to control the angle of incoming light without fully closing the blind. Faux wood is particularly low-maintenance — it won’t warp in steamy rooms and wipes clean easily.
Roman blinds — Softer in look and typically used in lounges and bedrooms. A thermal lining adds insulation value, helping slow heat transfer through the fabric.
Vision blinds — These alternate between sheer and solid fabric panels, giving you glare control without fully blocking the view or the light. Great for living rooms where you still want to see outside.
Perfect fit blinds — Clip directly onto uPVC window frames without drilling, creating a neat, gap-free finish. That close fit reduces heat leakage around the edges, making them particularly effective for conservatory glazing and French/patio doors.
Vertical blinds — Ideal for wide windows and sliding patio doors. Angle the louvres to reduce direct sun while keeping the room bright.
Our take: made-to-measure blinds always outperform off-the-shelf ones for heat control. A better fit means less light and heat creeping in around the edges — and they look sharper, too. We measure every window ourselves, so everything fits exactly as it should.
Should I close blinds to keep house cool?
Yes — but timing is everything.
The most common mistake is waiting until the room already feels like a sauna, then closing the blinds and hoping for the best. By that point, much of the heat has already entered and is trapped inside. Blinds and shutters prevent heat build-up; they can’t remove heat that’s already there.
The strategy that actually works:
- Early morning / late evening: open windows wide to ventilate — this is when the outside temperature drops below the indoor temperature
- Mid-morning onwards (south-facing): close or angle your blinds on the sunny side before direct sunlight reaches the glass
- Afternoon (west-facing): close west-facing blinds before the afternoon sun hits
On sunny days, keep windows closed on the sun-facing side of the house during the hottest hours. It feels counterintuitive, but letting hot air in doesn’t help.
Slat tip: tilt Venetian or shutter louvres upwards. This reduces glare while still allowing some diffused daylight — a much more comfortable result than fully closed blinds in a dark room.
If you’re out during the day, motorised blinds can adjust automatically via a timer or smart home system — so your rooms stay cooler even when nobody’s there to operate them.
Room-by-room recommendations
Bedrooms: Heat and light control matter most here. Shutters are excellent — they combine a strong barrier with adjustable louvres for airflow. Blackout or thermal roller blinds are a more affordable alternative.
Living rooms: Glare on the TV screen is a common frustration. Venetian blinds, vision blinds, or shutters all give you the flexible control you need without committing to a fully darkened room.
Kitchens: Easy to clean is the priority. Faux wood Venetians or roller blinds are both practical and effective.
Conservatories and patio doors: Perfect fit blinds work brilliantly here — no drilling, neat finish, good coverage. Vertical blinds handle wide sliding doors well. Shutters are a premium option that works beautifully if the budget allows.
Home offices: Screen glare is the enemy. Vision blinds or Venetians let you manage brightness precisely without going dark. Keep it comfortable enough to focus.

A few extra ways to keep cool
Window coverings do a lot of the heavy lifting, but a few other habits help:
- Keep internal doors closed to stop heat spreading from hot rooms
- Use a fan strategically — position it facing outward in the evening to push warm air out rather than just circulating it
- Layer if needed — combining blinds with curtains improves insulation, though it can reduce airflow, so it’s a trade-off
- Lighter backing = better reflection — if you’re choosing new blinds, a white or silver lining reflects more solar energy than a dark one
Results naturally vary with window size, orientation, glazing type, and insulation — so if you’re not sure what’ll work best in your home, that’s exactly the sort of thing we can advise on in person.
Why made-to-measure matters
A blind or shutter that fits properly is simply more effective. Gaps at the sides, top, and bottom are where heat sneaks through — and they’re more common with ready-made products than people realise.
Everything we supply at Jacksons Blinds is made to measure for your exact windows. We come to you, measure accurately, show you the options in your own home (with real samples in natural light), and handle the full installation. Measuring and fitting is always free, and everything comes with a guarantee.
We’re a family-run business based in the North East — no call centres, no pressure, just straightforward advice from people who know their products well.
Frequently asked questions
Are shutters or blinds better for keeping a room cool?
Both can be highly effective, but shutters generally offer superior insulation thanks to their solid construction and close fit to the window frame. That said, the right blind — particularly a solar reflective roller or a tilted Venetian — can perform very well. The best choice depends on your room, budget, and priorities.
Should I close blinds to keep house cool all day?
Not necessarily all day — but you should close or angle them before direct sunlight reaches your windows, rather than after. The key is to intercept solar heat at the glass before it builds up inside. Early morning and late evening are the best times to ventilate with windows open; during peak sun hours, keep the blinds closed on the sun-facing side.
Do light-coloured blinds keep a room cooler than dark ones?
Yes, generally. Lighter fabrics and finishes reflect more solar energy than darker ones, which tend to absorb heat. If reducing solar heat gain is a priority, opt for white, cream, or silver-backed fabrics where possible.
Which blinds are best for south-facing windows?
Solar reflective roller blinds or faux wood Venetian blinds (with slats tilted upwards) are among the most effective for south-facing rooms. Plantation shutters are also excellent here. The main thing is to lower or adjust them before the sun hits the glass directly.
Are shutters good for bedrooms in summer?
Yes — shutters are an excellent choice for bedrooms. Full-height shutters provide strong coverage, and the adjustable louvres mean you can keep some airflow without letting in direct sunlight. For maximum room darkening alongside heat control, solid panel shutters are worth considering.
Do perfect fit blinds help reduce heat in conservatories?
They can, particularly because their clip-in design creates a neater, more gap-free fit against the window frame than standard blinds. Fewer gaps means less heat can enter around the edges. For conservatory roofs and awkward-shaped glazing, pleated perfect fit options work well.
Can I still get airflow if the blinds or shutters are closed?
With slatted options — Venetians, shutters, vertical blinds, and vision blinds — yes. You can angle the slats or louvres to allow air movement while still blocking direct sun. Roller and Roman blinds when fully down don’t allow much airflow through the fabric, so ventilate during cooler parts of the day and then close them before the heat kicks in.
