Choose a brand that lasts when replacing your Nestor Martin Harmony 33 stove glass. Our Schott Robax glass is designed specifically for stoves. With correct installation and operation, your new glass will give you many years of use.

Market Leading Glass

We tested a number of the other brands available before choosing Robax due to its longevity, clarity and heat resistance.

The comparative clarity of Robax glass gives you an unbeatable view of your fire. Its heat resistance gives you added peace of mind, protecting you from any flying sparks or flames.

Thermal expansion is one of the top causes of breakage in stove glass. The glass expands as it heats and contracts as it cools. This leads to the glass weakening over time (at fixing points or any location that it may be in contact with metalwork), eventually leading to breakage. Robax has been designed to have minimal thermal expansion as it heats and cools, reducing the risk of breakage and extending its lifespan.

Product arrived securely packed. Dimensions are accurate and fitting was simple. No hassle at all and the prompt response to the order during this winter period is very much appreciated. Top Service.

Excellent service

The glass turned up exactly on time, although there was a bit of a hiccup with the Royal Mail tracking system - not their fault. Once I got the old glass out I realised my model was double glazed(!) and needed some mysterious new gasket. One call to SGR solved that and I had the 2mm tape within a day. Great service and products.
