Our main factory is in Bulgaria and was founded in 1991, we specialise in design and manufacture of UPVC windows and doors and with many partners across Europe we use the latest technology and high-quality materials ensuring we are always providing innovative design and compliant with all EU and BS standards. 

Being recognised throughout Europe for our outstanding range of products, high quality workmanship, professional staff and swift implementation from design to build have created a reputation of high standards for our company. 

Today the company has its own manufacturing base of aluminium and UPVC frames, glass packages, glass windows, curtain walls, aluminium railings, exterior blinds etc. The UPVC profiles have renowned technical parameters for thermal insulation, because of the structure and origin of the materials used, we don’t compromise on quality.

In order to satisfy the needs of our clients DELTA Global in 2019 extend its services into the UK and has a second factory manufacturing bespoke aluminium frames for windows, doors, by-fold etc. to satisfy many unique one-off projects. In addition, to ensure our high levels of customer service are maintained in 2022 we opened a sales office in the UK to expand our market share dealing directly with B2B within the new house build sector and large project division. 

By utilising both factories this has enabled us to provide one of the most comprehensive ranges of high quality UPVC and Aluminium windows and doors to market all through one sales office in the UK. We also provide an installation service for all of our products in the UK; our installation team are highly experienced engineers that understand the importance of ensuring that the installation matches the high-quality products and exceeds our customers expectations time after time.
