Hextable Primary School – a CosyPanels Case Study

How One School Transformed Its Conservatory into a Year-Round Learning Space

Many schools across England face the same problem with older conservatories: they are too hot in summer, too cold in winter, and too noisy when it rains. What begins as a promising extra classroom or group area often becomes an unused space for much of the year.

That was exactly the situation at Hextable Primary School in Swanley, Kent, until they discovered the benefits of the CosyPanels® insulated roofing system.

The Challenge

Hextable Primary’s 15-year-old conservatory had become impractical for daily use. It overheated in warm weather and dropped to uncomfortable temperatures in the colder months. The sound of rain on the old polycarbonate roof made it hard for pupils to focus. The low ceiling created a cramped feeling that limited how the space could be used.

For teachers and pupils alike, the conservatory had become a wasted area that no longer served its purpose.

The Solution

Working with the CosyPanels® team, the school decided to upgrade the space with an insulated roof system and a complete redesign, converting the existing lean-to structure into an Edwardian-style roof.

The results were immediate:

  • The room stayed warm in winter and cool in summer.

  • Outside noise was reduced, creating a calm and quiet learning environment.

  • The higher roof design made the space feel open and bright.

  • Teachers could once again use the space for lessons, reading groups, and after-school clubs.

The Results

The transformation has turned an underused conservatory into one of the school’s most valuable assets. It is now a flexible, welcoming area that supports both learning and wellbeing. The new roof also eliminates glare, improves comfort, and reduces running costs, all while maintaining a bright, natural light inside.

Teachers and pupils immediately noticed the difference. The school now enjoys a reliable, energy-efficient space that works all year round.

Why It Matters

This project shows how CosyPanels® can make a lasting difference, not only for schools but also for homeowners facing similar challenges with conservatories that are hard to heat, noisy, or uncomfortable.
