Pavement lenses are manufactured in clear flint glass.

Please note that we manufacture glass blocks only and sell in bulk to maintenance companies and installers.  We do not install into or even supply the concrete or metal frames also required.

The most common size used is a the 4in (100mm) square lens pictured right, supplied 1500 per pallet.

For specialist applications, such as the restoration of listed buildings, Nazeing Glass can produce wall blocks to specific shapes and sizes.  Drawings and preferably samples are required for this kind of work, which will require special moulds made to the required design. For more information please see subcontract production.

Cell blocks for use in secure locations are usually available from stock, please email for details.

Most standard sized glass blocks are mass produced ranges imported into the UK in volume and available through large DIY chains, builders merchants, etc. We do undertake processing of standard imported blocks (sandblasting, cutting and/or application of protective coatings etc.) for various customers, but do not supply the blocks themselves.
