Advanced Technology

Most uPVC French windows still use technology that’s been around for 20 years or longer, whereas Liniar’s multi-chambered window profile offers a far more technically advanced alternative. Designed completely from scratch in 2007, these window systems are designed and built for the challenges of the modern day.

Made in the UK

Using only Liniar products manufactured in the UK, we ensure a high standard for all our window systems. What’s more, our French windows are 100% lead-free, which is better for the environment and for you and your family. What’s more, every component of our uPVC French windows is easily recyclable at the end of its life, making this a more eco-friendly alternative to traditional timber frames.

Thermal Efficiency

Delivering thermal efficiency for a cost-effective price, our French windows are capable of achieving A+ WER (Window Energy Ratings) with cost-effective double glazing, and a U-value as low as 0.8 W/m²K with triple glazing. Available in either standard or EnergyPlus configurations, the multi-chambered profile of our system keeps heat inside the house, enabling homeowners to save money on energy bills.
