If your conservatory is freezing in February and unbearable in July, the issue usually isn’t the glass. It’s the roof. 🏠
Most older conservatories were built with lightweight polycarbonate or thin glazed roof panels. Very little insulation. Minimal structural depth. No meaningful thermal barrier.
In a Yorkshire climate of driving rain, cold snaps and high summer sun, that build-up simply cannot regulate temperature properly. 🌧️☀️
The result? Heat escapes quickly in winter and solar gain builds rapidly in summer.
A properly constructed tiled conservatory roof is different.
It isn’t just tiles on top. It’s a layered structural system:
• Engineered timber framework
• Adequate insulation depth between and beneath rafters
• Breathable membrane and ventilation detailing
• Structural deck and internal plastered ceiling
• Built to meet current Building Regulations
The performance comes from the build-up — not the finish. 🧱
When insulation depth is correct and the structure is designed properly, you create thermal stability. That’s what allows the room to function as part of the house, rather than a separate seasonal space.
At CRS, we approach every project as a structural upgrade, not a cosmetic replacement. In our climate, the structure determines comfort. 📐
