At GLAS our focus is on providing a high quality product range matched with a high quality installation service.

With a long standing reputation in the renewable energy sector our philosophy is simple – ‘you’re only as good as your last job’. We regard each project as a reference project and over the years have built our business on referrals.

We pride ourselves in our knowledge of the technologies for using renewable energy sources, and constantly strive to ensure this knowledge is reflected in our service.
