Orangeries have become an increasingly popular choice for homeowners looking to add a stylish, functional extension to their property. Despite that, our customers do still often worry about how well insulated they are throughout the year.
One of the most common questions we hear is, “Are orangeries warm in winter and cool in summer?”
Thanks to modern construction techniques and high-performance materials, the answer is yes! Orangeries regulate temperature throughout the year and what features make them a comfortable living space in all seasons.
Insulated Roofing for Year-Round Comfort
Unlike traditional conservatories, which often have fully glazed roofs, orangeries typically feature a part-solid, part-glazed roof design. This structure helps retain heat in winter while preventing excessive heat buildup in summer.
The other side of insulating an orangery comes from the design and use case that you have in mind for it.
Tiled and insulated roofs help maintain warmth during colder months by reducing heat loss as well as keeping heat out in summer months. Glass roof lanterns with solar control glazing allow natural light in without overheating the space in summer too, which is also great at keeping the structure warm in winter.
High-Performance Glazing for Thermal Efficiency
Modern orangeries use double or triple-glazed windows with advanced coatings that reflect heat when needed and retain warmth when temperatures drop. That means:
- Low-emissivity (Low-E) glass to reflect indoor heat back into the room during winter.
- Solar control glass to prevent excessive heat gain in summer while still letting in plenty of natural light.
- Argon gas-filled units for enhanced insulation.
- Brickwork and Solid Walls for Heat Retention
A key difference between orangeries and conservatories is the use of solid brick walls, which provide superior insulation compared to fully glazed alternatives. The thermal mass of brickwork helps regulate temperature by:
- Retaining heat in winter, keeping the space warm.
- Absorbing excess heat in summer, preventing overheating.
- Ventilation and Cooling Features
It’s not all about insulation either. Proper ventilation is also absolutely essential for keeping an orangery cool in summer. Some effective cooling solutions include:
- Roof vents and opening windows to allow warm air to escape.
- Bi-fold or sliding doors that open up the space to let fresh air in.
- Blinds and thermal curtains to reduce direct sunlight exposure and control temperature.
- Underfloor Heating and Smart Climate Control
For even more comfort in winter, underfloor heating is a great option, providing warmth without the need for radiators. Smart heating and cooling systems, such as thermostatic controls and air conditioning, can also be installed to create a perfectly regulated indoor climate. There’s a boatload of options to choose from to make sure the structure is always ideal for your use case.
