Window Partner Platinum Level

Award Winning Customer Service

We specialise in advanced glazing solutions where performance and aesthetics are equally important. Whether you're creating a low-energy passive house, modernising a commercial space, or adding a striking architectural feature, we ensure that every detail works in harmony—from design to installation.

Architects benefit from our in-depth technical support, with precise specifications that integrate seamlessly into any design vision. Contractors can rely on our expert team to provide smooth, on-schedule installations that meet demanding technical standards. And for homeowners, we offer clear, tailored guidance to help select the right products—combining style, comfort, and energy efficiency to reduce long-term costs.

Our trusted expertise is backed by a proven track record. In just five years of trading with Internorm, we achieved Platinum Level Window Partner status. Beginning as a Silver Level Partner in 2015, we advanced to Gold Level (2017–2018) and proudly reached Platinum from 2019–2025—a reflection of our commitment to quality, service, and technical excellence.

Our Comprehensive Warranty

We know that new windows and doors are a meaningful investment in your property. That’s why every product we supply is backed by a multi-year warranty—offering long-term protection and the reassurance that quality and reliability come as standard.
