Crystal-clear vision

Founded in 1991, our story began by solely producing toughened glass for a wide range of customers. In 1998, we moved into custom built premises in Ely to actively expand our production line and began supplying high-quality sealed units to commercial entities across the country.

Strong family values have been ingrained within our team from the beginning, which has allowed us to progressively build a reputation for outstanding quality and reliability in everything that we do.

Glass Half Full Attitude

Renowned for our flexibility and industry beating lead times, we can offer 1st class delivery via our own fleet of curtain-sided lorries, as well as Moffett & Hiab options. Thoroughly invested in our hardworking staff, cutting edge technology and state of the art equipment, this is what sets us apart from the competition; allowing us to rank as one of the best sealed glass unit suppliers in the UK.

Meet the team

Without our incredibly motivated and highly skilled team, Holloseal wouldn’t be in the excellent position that it finds itself in today.

Effectively combining the highest expectations built on a steadfast foundation of strong family values has enabled our team to flourish into a close-knit group of professionals, dedicated to delivering the highest quality sealed unit products and first-class service around.

Our processes

Processed under our EN1279 license in our custom-built multi-million-pound premises, everything we manufacture is made to order, competitively priced and of market-leading quality. Partnered with all the major glass and consumable suppliers, we are predominantly focused on the commercial sector - regularly investing in state-of-the-art automation and processing equipment, featuring three sealed unit lines, two heat soak ovens and two laminating lines.
