Services
Insulated Conservatory Ceiling
Our insulated conservatory ceilings transform uncomfortable spaces into usable rooms year-round. The ThermoSave system reduces heat loss in winter while reflecting summer heat, creating a stable temperature. This lightweight solution installs quickly without removing existing roofs, offering noise reduction, condensation control, and energy savings. Customers benefit from improved comfort and increased property value through enhanced thermal efficiency.
Tiled Conservatory Roof
Equinox tiled roofs provide permanent solutions for temperature-controlled conservatories. These insulated systems achieve exceptional U-values, combining steel or composite tiles with internal plastered finishes. The upgrade includes new guttering and fascias while maintaining natural light options through roof windows. Installation meets building regulations with 10-year guarantees, ensuring long-term durability and energy cost reductions for homeowners.
Window Replacement
We install energy-efficient UPVC and aluminium windows that enhance security while reducing heating bills. Our double or triple-glazed units feature multi-locking systems and thermal breaks to prevent condensation. Available in various colours and styles, these low-maintenance windows improve property aesthetics and acoustic insulation without compromising on safety or thermal performance.
Composite Door Installation
Our composite doors combine strength with modern design, featuring 5-point locking systems and triple-seal frames. These thermally efficient entrance solutions resist weather damage and require minimal maintenance. Available in multiple finishes, they enhance home security while improving energy efficiency through advanced insulation properties that reduce heat loss.
Conservatory Upgrade
Full conservatory transformations include roof replacements, new windows and doors, and interior enhancements. We revitalise outdated structures into functional living areas using thermal panels, insulated ceilings, and modern finishes. Projects maintain existing frameworks where possible, offering cost-effective improvements that extend usable space and increase property market appeal.

ThermoGreen work is great. But the electrician they us is nice bloke. But very unreliable. Fitted white spot lights when I asked for brushed chrome and still waiting for the certificate for electrical work so can be signed of by the council. It's now one and half months and sadly still waiting. paid alot of money. But it's not FINISHED to me.

We have recently had a conservatory built by Thermogreen, and it is lovely. The builders were friendly and nothing was too much trouble. We now have a lovely extra room to relax in all year round.

We have used Thermogreen for a number of house projects, they have always provided great service at a very reasonable price. Very responsive and kept us updated with timings and the lads are very clean workers.
