From humble beginnings...

Since starting out as a one man operation in 1987 Thermaglaze has grown into one of the country’s largest independent home improvement companies, recent buyouts of Yeovil based Firmseal and Bath based Clearglaze Windows have strengthened Thermaglaze’s foothold in the south west whilst still maintaining it’s friendly, no-pressure approach to business. Thermaglaze has cemented it’s reputation for being the number one go-to company in the area by ensuring it’s customers are supplied with the very best products available, fitted by highly trained and professional installers, all backed up with industry leading warranties and a second-to-none customer support service. Below is a brief bio of our journey so far…

1980s Exciting times for a small business.

Established in 1987, the Thermaglaze journey started with two men and one van. From the very outset standards were set high with a no compromise attitude and an underlying need to be the best. As a result, a small office was opened in Sutton Veny and a part time secretary employed. By 1990 the small office had been transformed into what would have been Thermaglaze first showroom. Vans had been sign written and small adverts were appearing in the local papers. More staff joined the team, many with a construction background were trained to meet the standards that were expected and embedded into the Thermaglaze ethos.

1990s Hello internet, it’s time for the journey to get serious

By the early 90s the industry was growing rapidly with new products being developed by many manufacturers. Working with Pilkington Glass, Thermaglaze were the first local company to offer Argon Gas filled units as standard this is an approach to improving standards that has continued throughout the years. Thermaglaze were always looking for the next generation of products and were often working with suppliers and manufacturers during this period to improve their range both technically and visually, the early 1990s were a time when you could have your windows in either White or Mahogany and with either White or Gold handles, now things were starting to change. By the mid-90s a thing called the World Wide Web was being labelled as the future and Thermaglaze started work on what might be described as their first website, although no one was sure if anyone would ever see it! By the end of millennium, a simple double-glazed window was no longer good enough. Energy efficiency and security standards were improving all the time it was exciting and challenging

2000s Finally some credibility for our Industry.

Thermaglaze were often working to be recognised and registered for installation standards. Working with suppliers such as Ultraframe they achieved a 98% BBA rating and were without doubt the local leading conservatory installation company. Growing increasingly frustrated at the lack of credibility within the industry Thermaglaze were always looking to have standards regulated. Although some may have thought it was an “April Fools” on 1st April 2002 window and door replacements came under the control of building regulations and therefore all installations had to comply, great news and just what the industry needed. Thermaglaze were again at the forefront helping to shape the future and were one of the first local companies to be self-regulated under the FENSA registration scheme. Now a large local company with many employees and contractors, Thermaglaze were experts not only within the industry but also in the marketplace, the became the first company to publish pricelists and the first company to hold open weekends, where potential customers would visit the showroom to meet with industry experts from all over the country. Never satisfied, product diversification and development were always at the top of the list and by the end of the 2000s Thermglaze were already supplying Energy Rated Windows looking to develop energy efficient products, so it was not surprising that the potential for Solar Panel installations was on the horizon.

2010s Solar, Aluminium and Certass

In April 2010 the government introduced the Feed In Tariff scheme for solar installations and Thermaglaze Solar was born! Consistently asked by our customers if we knew anyone who could help? Thermaglaze took the bold step of training installers, surveyors and electricians to comply with the regulations and became registered installers under the Microgeneration Certification Scheme. Today there are hundreds of households benefiting from a Thermaglaze Solar Installation. In 2012 Thermaglaze took over the Yeovil based Firmseal Brand, unfortunately it was too late to save the business but Thermaglaze endeavoured to assist Firmseal customers whenever possible and continue to do so. Today the Firmseal Brand remains in place for loyal customers and is fully serviced from the Thermaglaze head office. The window industry continued to develop with new colours and finishes now being offered as standard, the internet was now a driving force and customers were now demanding more options to suit more homes, Thermaglaze were keen to assist but knew that you could not compromise on the
