A profile system designed for enhanced aesthetics and ease of fabrication


The Logik profile system combines leading energy efficiency performance and aesthetics with ease of use, for the ultimate system. Logik is specially designed for ease and speed of fabrication and fitting, featuring a unique, patented knock-in bead system. Ideally suited for new build or replacement windows, its 70mm front-to-back dimension enables the seamless replacement of timber frames.

Logik is designed for improved aesthetics and clean sight lines, with its unobtrusive gasket line and slim profile. The profile features multiple chambers to enhance thermal efficiency and strength, and improve drainage. Available with chamfered or sculptured ovolo styles in a range of colours, Logik window profiles add a touch of distinction to any home.

The sustainable option


Logik features post-consumer recycled PVC-U in the central core of the profile with virgin PVC-U on seen faces. This ensures the same aesthetics and technical performancebut with more environmentally responsible benefits for today’s discerning customers. It offers the same benefits but with more sustainability – at no extra cost to you.

Enhanced aesthetics for a brighter outlook...

Not only does the innovative six-chambered outer frame option perform better than standard 70mm window profiles, it looks better too. Slimmer than standard systems, it gives any window a sleek, contemporary appearance, increasing the area of glass for improved sight lines and brighter interiors.


A++ performance

A+ Window Energy Ratings (WER) are achievable with Logik – offering market-leading window performance using argon gas. Logik is capable of an A+13 rating (double-glazed) and an A++20 rating (triple-glazed). What’s more, U-values as low as 1.2 can be achieved with a double-glazed unit and 0.8 with a triple-glazed unit.


PVC-U Thermal Inserts

PVC-U Thermal Inserts for Logik profiles are the sustainable way to improve your window energy efficiency. The multi-chambered design delivers significantly improved thermal performance, more efficient fabrication and 20% lighter weight than windows with conventional steel reinforcements.

Quality controlled manufacturing

Quality is carefully controlled and monitored throughout the manufacturing process of the Logik profile system. We have our own toolmaking and laminating facilities, manufacture in our own PVC-U compound mixing plant, giving us full control over product quality and consistency – right from the start.

High-performance products

Exposed to the elements, windows need to be hard-wearing, weather resistant and long lasting. The Logik window system will enable you to meet and exceed all of these requirements.


Up to 10-year guarantee

Logik profiles are guaranteed for ten years against warping, cracking and discolouration. That means you can give your customers the assurance of a robust, well-designed, precision-made product that’s built to last.
