Roof Lanterns

Designed from the ground up as an innovative thermally broken system, it provides excellent thermal performance – keeping cool in the summer and warm in the winter.

Roof Lights

Creating the illusion of open roof space, the minimalistic external and internal sightlines creates a sleek, modern appearance and is a stunning addition to any home extension.

Aluminium Conservatories

Aluminium is a lightweight yet very strong building material, especially for conservatory roofs where a double glazed sealed unit can be extremely heavy and requires strong support. Aluminium conservatories are energy efficient as each panel has a "thermal break" which effectively separates the exterior and interior surfaces to prevent heat-loss. Also, all our aluminium conservatories come with toughened safety glass double glazing as standard too.
