In today’s architectural landscape, where speed, sustainability and aesthetic impact must converge, glazing into precast concrete has become a vital solution. OAG’s deep expertise in integrating high-performance glazing systems into precast façades enables us to deliver superior results – both visually and structurally on some of the UK’s most advanced developments.
Preglazing has evolved from a niche concept to a core strategy in modern construction, providing an efficient, sustainable and high-quality solution for both new builds and refurbishments. OAG has been at the forefront of this transformation, working with trusted partners like Techcrete, Thorps and Grants to deliver seamlessly integrated glazing systems across notable projects:
Begbroke Science Park
At Begbroke Science Park, our expertise in glazing integration was showcased in our first major project incorporating glazing directly into precast panels. Collaborating with Techcrete, we installed 250 windows across two blocks. The pre-glazing process enabled a faster build schedule, maintained airtight tolerances and minimised on-site disruption, resulting in an energy-efficient building that combined cutting-edge technology with sustainable design.

Seamless Integration, Enhanced Delivery
Glazing into precast demands absolute precision. The tolerances are tight and coordination between trades must be meticulous. It’s not just about installing a window – it’s about ensuring the glass performs as a structural and visual component of the façade system from the moment the panels arrive on-site.
Benefits of Glazing into Precast
Preglazing offers several benefits, including faster project delivery, improved safety, superior quality control and cost efficiency. By prefabricating glazing systems off-site, we eliminate the need for on-site glazing crews and scaffolding, accelerating construction and reducing costs. This method also improves safety by minimising hig-risk on-site glazing work and ensures consistent quality through factory-controlled processes. Additionally. preglazed façades support sustainability by reducing waste and enhancing energy performance, making them ideal for projects targeting BREEAM, WELL and Net Zero certifications.
This approach demands a partner who understands the interface – literally and figuratively, At OAG, we know what it takes to get it right the first time, delivering façades that perform as beautifully as they look.
