Thermoshield Windows

The company was founded in June 1983 by partners Terry Sales and Jean Sergeant who quickly established Thermoshields reputation as a customer focussed business who do not compromise on quality. the company manufactured it’s own range of products using only the best quality profile from the UK’s leading providers. From the beginning, the company manufactured it’s own range of products using only the best quality profile from the UK’s leading providers. This meant that customers requiring something out of the ordinary could be easily catered for, further cementing Thermoshields reputation as a company who could be relied upon to meet any request.. The expanding business soon outgrew it’s first location on Laurence Industrial Estate, Eastwood and moved to larger premises on Purdeys Way Industrial Estate. With the winning of major commercial contracts, new machinery was bought to enable higher production and the unit next door was acquired. Additional staff were employed and the company began a steady expansion to become one of the areas best known double glazing firms.

In 2004, Terry Sales & Jean Sergeant decided to emigrate to Spain which prompted a management buyout by Neil Haylock & Scott Austen, who were the existing senior financial team. They have carried on the same ethos of quality and customer service in a tradition which has continued uninterrupted since 1983 – making Thermoshield one of the longest operating companies in the area. In fact, the company are on the verge of outliving their 10 years insurance backed guarantee by 3 times!

The new team drew upon their experience to boost commercial contracts to a new high. Thermoshield have manufactured and installed windows and doors for Housing Associations such as The Guinness Trust, Anchor Housing, South Essex Homes and the Orbit Group. Attention to detail and the ability to bring in projects on time and on budget have led to regular repeat contracts. The company also enjoys ongoing long term relationships with Borough Councils in London & the Home Counties, Essex, Kent, Norfolk, Suffolk and Sussex. Amongst blue chip clients are companies like Proctor & Gamble, Galliford Try Construction and the Ministry of Defence.

It was decided at an early stage not to try and compete with companies offering cheaper, poorer quality products. Thermoshield prides itself on offering a superior product with outstanding service at a competitive price. Thermoshield has always used the best raw materials, manufactured under stringent British Standards Institute procedures. The loyal and highly skilled workforce ensure that each window, door or conservatory made is manufactured as though it was for their own homes!

Thermoshield now offer quality windows, doors and conservatories to homes all over the South East. Our installation teams are the best in the business and pay as much attention to leaving your home neat and tidy as they do to the fitting of your windows.
