How To Keep Your Loft Conversion Cool in Summer

Thinking of converting your loft, but worried it’ll be too hot in the summer? You’re not alone. One of the most common questions we’re asked is: “Do loft conversions get warm in summer?” The short answer is yes, they can. But with the right design choices and a few smart additions, you can enjoy a comfortable, airy space all year round.

We don’t just build beautiful lofts. We build rooms your family can genuinely live in, whether that’s a peaceful home office, a teenager’s bedroom, or a nursery for a new arrival. And part of that means making sure your loft is comfortable in every season.

Here’s how we answer your questions to ensure your loft conversion stays cool during the hottest months of the year.

1. How do I choose the right windows for my loft conversion (and decide where to put them)?

A Velux loft conversion is a fantastic addition to any home. They let in lots of natural light and help ventilate the space effectively. But placement is key.

Our designers will look carefully at the orientation of your loft. South-facing windows will let in the most sun, so we’ll advise on glazing options and positioning to reduce overheating. Adding opening roof windows on opposite sides can also allow for cross-ventilation, keeping fresh air moving through your loft naturally.

2. Will high-performance insulation keep my loft cool?

Insulation isn’t just about keeping warm in winter; it’s also crucial for keeping heat out in summer. We use high-spec insulation materials that regulate temperature effectively, keeping your loft cooler on hot days and warmer on cold ones.

Many of our customers are surprised by how much difference this makes. It’s one of the reasons we never cut corners and are renowned for treating every home like it’s our own.

3. Can I install ventilation systems or air conditioning in my loft conversion?

For extra comfort, especially during heatwaves, some of our clients choose to install small air conditioning units or mechanical ventilation systems. These options don’t have to be bulky or unsightly. Discreet wall-mounted units or integrated systems can be fitted to suit the style of your loft.

We’re always happy to talk you through the pros and cons and work to ensure you get an effective solution that is in keeping with the space we’ve designed together.

4. What blinds and window treatments are good for loft conversions?

Solar blinds or blackout blinds designed for Velux windows can make a big difference, especially during the warmest part of the day. They block out direct sunlight and help keep the space cooler. We can advise on the best options to suit your style and budget and work them into our design and build process.
