Floating Central Mullion
Elite Thermal Performance
Secured by Design
We supply and fit high-performance French doors that keep your home warm, quiet, and secure throughout the seasons.
Our French doors offer exceptional energy efficiency. Liniar’s multi-chambered PVCu profiles act as a barrier to heat loss, achieving U-values as low as 1.0~W/m²K with triple glazing. The patented thermal dam and co-extruded bubble gaskets form a continuous seal to prevent winter draughts, keeping your home warm and lowering your energy bills.
We provide maximum weather protection. Liniar French doors are rigorously tested to withstand extreme wind, rain, and cold air. They utilize patented co-extruded bubble gaskets that form a continuous seal—even in the corners—ensuring your doors remain entirely weather-tight and leak-free for years to come.
Designed to fit your specific needs, Liniar French doors can open inwards or outwards to suit your living space. Choose between a beautifully curved sculptured profile or a flat, contemporary chamfered finish. We also offer Part M compliant low thresholds in silver or gold for seamless, step-free access.
Personalise your French doors to match your home’s unique character. Liniar’s premium PVCu profiles are available in a beautiful selection of stock and special foiled colours, including classic White Foil, Cream Foil, Chartwell Green, and authentic woodgrain finishes like Golden Oak, Irish Oak, and Rosewood. You can also choose dual-colour options, giving you a distinct look on the outside while keeping the inside perfectly coordinated with your interior decor. Complete your design with double or triple-glazed units, clear, obscure, or custom leaded glass patterns.
The sculptured profile option features elegant, swept curves that mimic the appearance of traditional timber joinery, perfect for adding classic character to country cottages, period properties, and traditional homes.
The chamfered profile features neat, clean bevelled lines that offer a sleek, flat, and modern look. This minimalist styling is highly popular for contemporary extensions, renovations, and new-build properties.
At AK uPVC Solutions, we are a family-run business based in Buckingham, dedicated to fitting high-quality doors with care, honest advice, and workmanship you can rely on.
