Starglaze Celebrates 25 Years with Secured by Design

Established in 1974, Starglaze is a family-owned British manufacturer, supplier and installer of windows, doors and conservatories, serving homeowners across Lincolnshire, Nottinghamshire, Newark and the surrounding areas. Over five decades, the company has built a reputation for product quality, technical expertise and customer service, combining traditional family business values with continued investment in manufacturing technology and innovation.

Starglaze’s history is also closely linked with its sister company, fellow SBD member Sternfenster, which has grown into one of the UK’s leading trade fabricators of PVC-U and aluminium windows and doors. The wider business supplies products to customers across the UK, with manufacturing operations based in Lincoln.

A Commitment to Quality and Innovation

Starglaze manufactures a broad range of PVC-U and aluminium products, including windows, residential doors, bifold doors and patio doors. Its offering combines different styles and materials to meet the needs of homeowners, builders and property professionals, with products designed to deliver security, energy efficiency and lasting performance.

The company has continued to invest in its manufacturing capabilities and was among the first fabricators in the UK to introduce seamless welding technology for PVC-U windows and doors. This innovation supports the production of clean, consistent frame finishes while demonstrating the importance the business places on improving its products and processes.

As a manufacturer and installer, Starglaze also manages the customer journey from the initial survey through to installation, supported by in-house teams and quality control procedures. Its emphasis on customer care and repeat business has helped establish its position within the regional home improvement market, while its manufacturing expertise supports the wider group’s national supply operation.

25 Years with Secured by Design

Starglaze’s long-standing membership with Secured by Design reflects the importance it places on security when developing and manufacturing windows and doors.

Over the past 25 years, the security landscape has continued to evolve, with increasing emphasis on independently tested products and recognised standards of performance. Secured by Design works with the industry to encourage the use of security products that have been tested and certified to meet the relevant requirements, helping to reduce opportunities for crime.

Both Starglaze and Sternfenster have substantial portfolios of window and doorset products recognised under the Secured by Design Police Preferred Specification.

This breadth demonstrates the companies’ continued commitment to providing security-conscious solutions across different materials, designs and applications, supporting the needs of homeowners and the wider construction industry.

Mike Parczuk, Managing Director of Starglaze, said: “When we joined Secured by Design 25 years ago, independently tested security was far from the norm. Today it’s what homeowners, housebuilders and specifiers rightly expect. We’re proud that across Starglaze and Sternfenster, security has always been designed into our products from the start rather than added on afterwards. Our thanks go to the SBD team for a partnership that has kept pushing us to raise the bar.”

Alfie Hosker, Secured by Design, commented: “Congratulations to Starglaze/Sternfenster on 25 years with Secured by Design. This milestone reflects a lasting commitment to quality, innovation and helping create safer homes and communities. I look forward to another successful 25 years and beyond with them.”

As Starglaze celebrates 25 years with Secured by Design, the milestone recognises an established relationship built around secure products, quality manufacturing and shared commitment to creating safer homes and communities. With its ongoing investment in technology and its close links with Sternfenster, Starglaze continues to build on its long manufacturing heritage while maintaining security as an important consideration in its products.
