Neil Caddy’s back, and this time, he’s not messing about.

We’re dropping a breeze block.

Every week we’re putting our glass to the test to answer one very important question…

"Will it Smash?"

It’s the biggest drop yet - will our toughened glass survive or is this the end of the line?

Let us know in the comments what you’d like to see Neil drop next.

We stock and supply laminated glass in a wide range of thicknesses, all cut to size and ready to fit.

Laminated glass doesn’t shatter when broken, reducing the risk of injury. Ideal for shopfronts, doors, windows, balustrades and public spaces.

We also offer acoustic laminated options to help reduce noise, along with tinted, patterned and energy-saving variations to suit your space.

Neil Caddy’s back, and this time he’s dropping a plant pot.

Every week we’re putting our glass to the test to answer one very important question…

"Will it Smash?"

It’s ceramic, it’s chunky, and it’s coming in fast.

Will our toughened glass hold up, or will it all come crashing down?
