Conservatory roof replacement Hemel Hempstead is one of the most effective ways to reclaim a room that has become too cold to use in winter and too hot in summer — and this recent project is a perfect example of what’s possible.
Conservatories are one of the most popular home additions in the UK — and one of the most underused. The culprit, more often than not, is the roof. Original polycarbonate panels may be cost-effective to install, but they offer very little in the way of insulation. The result is a space that becomes unbearably hot in summer and bitterly cold in winter, ultimately sitting empty for much of the year.
That was exactly the situation facing this Hemel Hempstead family, who contacted Efficway to explore their options. After an initial consultation, the recommendation was clear: replace the existing polycarbonate panels with ThermoPanels — a high-performance insulated roof panels.

The problem with polycarbonate
Polycarbonate has been a standard material for conservatory roofs for decades. Lightweight and relatively inexpensive, it became the go-to choice for many builders and developers. But its thermal performance is poor. In summer, it allows solar heat to build up rapidly, turning the conservatory into a greenhouse. In winter, heat escapes easily, leaving the space cold and draughty.
For many homeowners, this means their conservatory is only comfortable for a few weeks of the year — a significant investment that goes largely unused. Heating costs can also be affected, as the poorly insulated space draws warmth from the rest of the home.
The ThermoPanels solution
ThermoPanels are a premium insulated roof panel with a PVC-UV/XPS/PVC-UV construction, manufactured in Europe and engineered to deliver exceptional thermal efficiency. Unlike polycarbonate, they dramatically reduce heat loss in winter and prevent solar heat gain in summer — meaning the conservatory maintains a comfortable, stable temperature all year round.
The Hemel Hempstead installation was completed in a single day by the Efficway team. The existing polycarbonate panels were carefully removed and replaced with ThermoPanels, fitted precisely to the existing roof structure. No major structural work was required, and the result was immediate.
The transformation was immediate — a room that was once avoided is now one of the most used spaces in the home, whatever the season.
