Structural Glass: Frameless Elegance

Our modern, premium frameless structural glass has been developed over 30 years, utilising advanced commercial glass technology and structural sealant applications to create rooms made entirely of glass. A frameless glass box extension delivers a true WOW factor, offering uninterrupted views of the outdoors while meeting stringent thermal and structural regulations with a unique, practical design.

Many of our clients seek to harmonise traditional listed buildings with a contemporary glass box aesthetic.
