Peter Grundy, vice president operations at Liniar, believes success in today’s fenestration sector depends on building strong, transparent partnerships that give fabricators the confidence to plan ahead, knowing their systems supplier will deliver – literally and figuratively.

In a market where efficiency and reliability are crucial, fabricators and installers are facing growing pressure to deliver more – faster and without compromise! With fluctuating demand, material challenges, and an ever-tightening labour market, the need for dependable supply chains and consistent quality has never been greater.

Few things disrupt production schedules more than a supplier who can’t deliver on time or in full. Missed deadlines and incomplete orders ripple through fabrication, installation, and customer satisfaction.

At Liniar, we’ve made reliability our foundation. Our On Time, In Full rate consistently exceeds 99%, which means customers can plan production with confidence.

Operating from our impressive 375,000 ft² facility in Derbyshire, Liniar maintains nearly 10,000 SKUs, holding over £10 million of stock ready for immediate dispatch. Supported by a 175,000ft² warehouse and a dedicated UK-wide transport fleet, our logistics network ensures fabricators receive the right products exactly when they’re needed.

This operational efficiency not only minimises downtime but supports sustainable growth for customers scaling their businesses.

Quality You Can Trust, Every Time

Quality inconsistencies create issues on the shop floor and, potentially, costly call-backs on site. Liniar’s reputation as the UK’s most invested PVC-U systems house comes from a commitment to world-class manufacturing standards and smart design principles.

Our customers expect profiles that perform flawlessly. That’s why we continually invest in advanced extrusion technology, precision tooling, and rigorous quality checks at every stage.

Each Liniar profile is engineered with fabricators in mind – optimised for ease of machining, minimal waste, and maximum performance. The result? Fewer production headaches and greater profitability for our customers.

Simplifying Supply Chains Through a Single Source

Coordinating multiple suppliers often leads to inconsistencies, colour variations, and administrative strain for fabricators. At Liniar, we remove that complexity by providing a complete, single-source solution across both PVC-U and aluminium systems – giving customers one trusted partner for every requirement.

With all products colour-matched, fully compatible, and manufactured to the same exacting standards, fabricators gain a seamless, reliable supply chain that saves time and reduces risk.

It’s about giving them simplicity, consistency, and confidence in every order from a single point of contact.

Partnership as a Path to Progress

As the fenestration sector continues to evolve, collaboration will define the next decade of growth. At Liniar, we’re not just supplying profiles – we’re partnering with customers to help them adapt, innovate, and thrive. Continuous improvement is part of our DNA, and our focus remains on supporting the people who want to drive this industry forward.

With that forward-thinking approach, we continue to set the standard for reliability, quality, and partnership in UK fenestration.
