How to Keep Your Conservatory Cool in Summer

June 17, 2025|News

As the summer months approach, many homeowners across the North East find themselves facing a familiar dilemma: how to keep their conservatory cool when temperatures soar. While conservatories are wonderful spaces that bring natural light into your home, they can quickly become uncomfortably hot during the warmer months, making them virtually unusable when you need them most.

If you’re struggling with an overheated conservatory, you’re not alone. The good news is that there are numerous effective ways to transform your space into a comfortable retreat, even on the hottest days of the year.

One of the most effective ways to transform your conservatory is to get a conservatory roof replacement, which can dramatically increase the thermal efficiency of your space and create a comfortable, year-round conservatory.

The historic problem: why conservatories get too hot

Conservatories have long been plagued by temperature control issues. During summer, they can feel like greenhouses, while in winter, they’re often too cold to use comfortably. This dramatic temperature fluctuation has made many conservatories seasonal spaces rather than year-round living areas.

The root of this problem lies in traditional conservatory construction. Most older conservatories were built with single glazing and basic polycarbonate roofs, which offer minimal thermal efficiency. These materials are particularly poor at regulating temperature – they allow heat to build up rapidly in summer and let warmth escape quickly in winter.

A polycarbonate roof, while cost-effective initially, simply cannot provide the insulation needed to maintain comfortable temperatures throughout the year. The lack of ventilation in many traditional designs further compounds the issue, creating spaces that trap hot air with no effective means of cooling.

The solution: thermally efficient conservatory roofs

The most effective way to address temperature control issues is through a conservatory roof replacement. A new conservatory roof with proper thermal efficiency can completely transform your space, making it comfortable and usable throughout all months of the year.

At Tyneside Home Improvements, we specialise in high-performance conservatory roof systems that tackle temperature control head-on. We offer a variety of roofing options including fully glazed roofs, solid tiled roofs, and hybrid systems that offer the best of both worlds.

Glass conservatory roofs

Our glass conservatory roofs feature advanced glazing technology with excellent thermal performance. Available in glass thicknesses from 24mm to 35mm, these roofs incorporate solar control glass that helps regulate interior temperatures by blocking harmful UV rays while still allowing natural light to flood your space.

The high-quality glazing can be specified in neutral or tinted options – aqua, blue, or bronze – to provide additional solar shading. These roofs offer superior energy efficiency compared to traditional alternatives, helping to keep your conservatory cooler in summer and warmer in winter.

SupaLite tiled conservatory roofs

For homeowners seeking maximum thermal efficiency, our SupaLite tiled roof systems represent the best option for temperature control. These super-insulated designs feature 100mm insulation between aluminium rafters and 72mm insulated plasterboard, creating an effective barrier against heat transfer.

SupaLite roofs can incorporate Sky Vista glass panels, which use innovative solar control glass to regulate room temperature while maintaining brightness. This combination allows you to enjoy natural light without the excessive heat build-up associated with traditional conservatory roofs.

Do I need planning permission for a conservatory roof replacement?

Many homeowners wonder whether they need planning permission for a conservatory roof replacement. Generally, replacing like-for-like doesn’t require planning permission, but switching from a glazed roof to a solid tiled system may need approval, particularly if it changes the conservatory’s appearance significantly.

Our experienced team at Tyneside Home Improvements can advise on planning requirements specific to your project and help navigate any necessary applications, ensuring your roof replacement proceeds smoothly.

How to keep conservatory cool: additional tips

While a new conservatory roof is the most effective long-term solution, there are several other methods to help keep your space cool:

Conservatory blinds and window treatments

Roof blinds and conservatory blinds are a popular choice for controlling direct sunlight. Venetian blinds offer adjustable light control, while roller blinds provide complete coverage when needed. Consider conservatory roof blinds specifically designed for sloped surfaces.

Ventilation solutions

Improving air circulation is crucial. Install roof vents to allow hot air to escape naturally, and consider adding a ceiling fan to encourage air movement. Opening doors and windows during early morning and evening hours helps create cross-ventilation.

Window film and cooling film

Applying window film with UV protection to conservatory windows can significantly reduce heat gain. This adhesive layer blocks harmful UV rays while still allowing light through, making it an ideal way to reduce the temperature of the room without sacrificing brightness.

Flooring considerations

Your flooring choice affects how heat is absorbed and retained. Stone flooring or porcelain tiles stay cooler than darker colours and soft fabrics. Natural hardwood floors are also a good option, as they don’t retain heat like some synthetic materials.

Air conditioning and cooling systems

For immediate relief, portable air conditioners can provide effective cooling, though they represent a more significant investment in energy costs. They’re particularly useful for south facing conservatories that receive intense sunlight throughout the day.

Smart design choice

Consider the overall design of your space. Lighter colours reflect heat better than darker alternatives, while strategic placement of plants can provide natural cooling through transpiration and shade.

Transform your conservatory into a comfortable space year round

Don’t let another summer pass with an uncomfortably hot conservatory. Whether you’re looking to replace an old conservatory roof or explore other cooling solutions, the key is taking action before the hottest days arrive.

A thermally efficient conservatory roof replacement not only solves temperature control issues but also improves energy efficiency, reduces energy bills, and increases your home’s value. It’s an investment that pays dividends in comfort and usability year-round.
