Sealed Units

Crown Glass & Glazing Company

A sealed unit is a construction of 2 panes of glass spaced apart with a spacer bar made to form a cavity between the panes. A desiccant is incorporated in the spacer bar to dry up any residual moisture. An edge sealant is then applied to all four sides to form an airtight seal.

Slimline units are a new concept in double glazing popular with joiners in conservation areas to replace single glazing with energy-efficient slimline double glazing.

All our units are made inhouse and tested yearly to current manufacturing specifications as listed on our homepage and are guaranteed for five years subject to glazing conditions.

We offer Swiss warm edge bar in various colours from 8mm up to 20mm, we also stock aluminium spacer bar from 4mm up to 20mm in silver, black, bronze, white and even gold.

We manufacture any combination of glasses, including energy-efficient low e, toughened safety glass, acoustic and self-cleaning glasses with many more options available. Argon gas filling is also possible to give higher thermal insulation performance.

Sealed Units

We also manufacture triple glazed units which are the same as above using three panes of glass, a triple glazed unit is better for insulation than a double glazed unit and from a safety point of view harder to break, we can also insert your old (or new) traditional leads into triple glazed units making them easier to clean and protect.
