Why is My Conservatory So Hot?


Understanding the Heat: The Conservatory Conundrum

Why is your conservatory so hot? This is a common question among homeowners, particularly in the UK where conservatories are a popular home addition. The primary reason lies in the very nature of conservatories. Being largely made of glass, these structures work similarly to greenhouses, trapping solar radiation and converting it into heat. This phenomenon, known as the greenhouse effect, can lead to uncomfortably high temperatures, particularly during sunny days.

Do Blinds Help Keep Conservatory Cool?

Window Treatment and Temperature Control

Blinds, particularly those designed to reflect sunlight, can be effective in reducing the heat inside your conservatory. When used correctly, they can provide a layer of insulation and shade, reducing the amount of sunlight directly heating up the room. However, blinds alone may not be sufficient on particularly hot days, and additional measures might be necessary.

Quote on Blinds Use in Conservatories

“Utilising blinds can be an effective way to control temperature in your conservatory. Not only do they provide shade, but they also add an aesthetic element to your space.”

How Do I Make My Conservatory Less Hot?

To make your conservatory less hot, you can implement the following strategies:

  1. Install Heat-Reflective Glass: This type of glass is designed to reflect heat and UV rays, helping to keep the conservatory cool.
  2. Use Blinds or Curtains: As mentioned before, these can provide shade and reduce direct sunlight.
  3. Consider Proper Ventilation: Good airflow can greatly help to reduce the heat.
  4. Consider a Cooling System: A portable air conditioner or a ceiling fan can also help regulate temperature.

What Can I Put on My Roof to Reduce Heat?

One effective strategy to reduce heat in your conservatory is by treating the roof. Heat-reflective roof panels or films can be installed to reflect sunlight and reduce heat absorption. Another option is polycarbonate roofing, a lighter, more heat-resistant alternative to traditional glass.

Will a Carpet Make a Conservatory Warmer?

Interestingly, the type of flooring in your conservatory can affect its temperature. Carpets, due to their insulating properties, can indeed make a room feel warmer. They can trap heat, thus raising the room’s overall temperature. However, this effect might be more pronounced during colder months, offering a cozy environment.

Are Modern Conservatories Too Hot?

The perception of modern conservatories being too hot stems from their efficient use of glass and the resultant greenhouse effect. However, with the advancement in technologies and materials, such as low-emissivity glass, heat-reflective blinds, and efficient cooling systems, modern conservatories can be made comfortable even during the warmest days.

Comparison of Different Cooling Strategies for Conservatories

Strategy Pros Cons
Heat-Reflective Glass High heat reflection, does not obstruct view More expensive than regular glass
Blinds or Curtains Easy to install, affordable, adds aesthetic value Does not prevent heat absorption completely
Ventilation Promotes natural cooling, affordable May not be effective on extremely hot days
Cooling Systems Can significantly reduce temperature Increases energy usage, could be expensive

In conclusion, while conservatories can become hot due to the greenhouse effect, there are various strategies available to manage this issue. The choice of glass, roof materials, blinds, and flooring, combined with efficient ventilation and cooling systems, can help in regulating the temperature.

A Tailored Approach to Temperature Management

Ultimately, the key to maintaining a comfortable temperature in your conservatory involves a multi-faceted approach that takes into account your specific circumstances. The local climate, the orientation of the conservatory, the surrounding vegetation, and your personal usage patterns all play significant roles.

It’s crucial to note that each conservatory is unique. What works for one may not be the perfect solution for another. For instance, in a conservatory that’s exposed to direct sunlight throughout the day, installing heat-reflective glass and blinds may be the most effective strategy. On the other hand, a conservatory that only receives direct sunlight for a few hours might benefit more from enhanced ventilation and cooling systems.

Innovation and Modern Conservatories

With the advancements in technology and better understanding of the factors contributing to conservatory heat, contemporary conservatories are no longer doomed to be “too hot”. Manufacturers and designers are now better equipped to create structures that not only look aesthetically pleasing but also function efficiently in terms of temperature management.

Quote on Modern Conservatories

“Modern conservatories are a far cry from their older counterparts. With innovative design and materials, they can be transformed into comfortable, year-round living spaces.”

For example, some modern conservatories feature glazing with advanced properties such as low-emissivity and thermally insulating layers. These types of glass can reduce heat transmission, keeping the space cool in the summer and warm in the winter.

The Importance of Professional Guidance

If you’re considering modifications to your existing conservatory or planning to build a new one, professional advice can be invaluable. Experienced conservatory designers and builders can provide insights into the best materials and configurations for your specific situation.

It’s worth noting that while the cost of installing advanced materials and technologies may seem high initially, the long-term benefits of a comfortable, energy-efficient conservatory can often outweigh these costs.


Despite the challenges, it’s entirely possible to have a conservatory that remains comfortably cool even during the peak of summer. It’s all about understanding the principles behind heat build-up and employing a tailored strategy to control it. By combining technology, clever design, and careful material selection, you can create a conservatory that’s perfect for year-round use, making it a worthy addition to your home.
