Our triple-glazed windows provide superior thermal insulation, reducing energy bills and noise pollution. Designed with advanced low-E glass and argon-filled panes, they enhance home security and comfort. Ideal for colder climates, these units maintain consistent indoor temperatures year-round.
Conservatory Roofs
We install insulated conservatory roofs with U-values as low as 0.15 W/mK, transforming unusable spaces into comfortable living areas. Options include tiled, glass, and lantern designs, all compliant with building regulations for durability and energy efficiency.
Durabase Extensions
Durabase offers rapid, low-disruption extensions using pre-engineered modular systems. These thermally efficient bases reduce construction time by up to 70%, with a 25-year guarantee. Perfect for garden rooms, conservatories, or single-storey additions.

We repair misted units, broken seals, and faulty hardware to restore window functionality. Services include replacing hinges, locks, and glass panes, extending the lifespan of existing installations while maintaining security and thermal efficiency.
