Polycarbonate vs. Glass Roofs: Which Benefits More from Insulation?
When it comes to conservatory roofs, two of the most common materials used are polycarbonate and glass. While both have their own advantages, they also share a major drawback—poor insulation. Whether you have a polycarbonate or glass roof, you may have noticed that your conservatory gets uncomfortably hot in the summer and freezing cold in the winter. The good news is that insulated ceilings can significantly improve thermal efficiency and year-round comfort. But which type of roof benefits the most from insulation? Let’s explore.
Understanding the Differences Between Polycarbonate and Glass Roofs
Polycarbonate Roofs
Polycarbonate is a lightweight, durable plastic that has been a popular choice for conservatories for years. It’s relatively affordable and allows plenty of natural light to enter the space. However, it has a number of drawbacks, including:
Poor thermal performance – Polycarbonate lacks natural insulation properties, meaning it struggles to retain heat in the winter and blocks very little solar heat in the summer.
Noise issues – Rain and wind can create a loud drumming noise on polycarbonate roofs, making conservatories less pleasant during bad weather.
Discoloration over time – Polycarbonate can become discoloured or brittle over the years, reducing its aesthetic appeal.
Glass Roofs
Glass roofs offer a more premium look and often come with modern double-glazing or even solar-reflective coatings. Benefits of glass roofs include:
Better thermal performance than polycarbonate – High-quality double-glazed glass helps retain heat better than polycarbonate, reducing heat loss in winter.
More natural light and clarity – Glass provides a clearer, more aesthetically pleasing view and allows more light to enter without distortion.
Reduced noise from rain – Compared to polycarbonate, glass absorbs more sound, making it a quieter option during bad weather.
Which Roof Benefits More from Insulation?
Both polycarbonate and glass roofs suffer from heat loss in the winter and excessive heat buildup in the summer. However, polycarbonate roofs tend to benefit more from insulation because they have poorer thermal efficiency to begin with. Here’s why:
Greater reduction in heat loss – Since polycarbonate struggles to retain heat, adding insulation can make the biggest difference in keeping your conservatory warmer in winter.
Improved noise reduction – Insulated ceilings can help dampen the noise of rain and wind, making conservatories with polycarbonate roofs much quieter.
More stable temperatures year-round – Insulation helps mitigate the extreme temperature fluctuations that are common with polycarbonate roofs.
That being said, glass roofs also benefit significantly from insulation, especially if they are single-glazed or lack thermal coatings. Insulating a glass-roofed conservatory will:
Prevent excessive heat loss in winter.
Reduce glare and overheating in summer.
Improve energy efficiency, lowering heating and cooling costs.
Conclusion: Insulation is Essential for Both Roof Types
While polycarbonate roofs see the most dramatic improvement from insulation, both polycarbonate and glass conservatory roofs benefit significantly from an insulated ceiling. By installing a high-quality insulated conservatory ceiling, you can transform your conservatory into a comfortable, usable space all year round—regardless of the type of roof you have.
