The company’s installers are the best in the business, with regular in-house and manufacturer training to ensure they stay at the top — Spectrum’s installers are frequently praised in Trustpilot reviews for the quality of their work and for their attention to details.

Spectrum only deal in three brands: Internorm of Austria, Solarlux of Germany and Kastrup of Denmark. These are the three brands that the company believes are the best available in the UK. Each offers something different but all combine market-leading innovation with exceptional performance, style and obsessive engineering. 

Kastrup Windows combine exceptional thermal performance with Danish style; Internorm of Austria are probably the finest windows in Europe; and Solarlux of Germany are still market leaders in bifold doors and glass extensions after nearly 40 years.
