Designed and developed in one of the most advanced extrusion facilities in Europe, our windows are unique and are a superior-performance PVCu profile system and product range.

Combining innovative design with advanced manufacturing techniques, they represent the next generation of PVCu windows and doors.

Our products meet the sustainability demands of the current climate without compromising on quality or performance.

Frames & Glazing


Weathermaster frames are designed with multiple internal chambers within the profile system. Each chamber acts as a barrier against heat loss from inside the home and against cold air entering from outside, ensuring excellent thermal efficiency.


Weathermaster energy efficient glazing units feature energy reflecting glass as standard, which maximises heat gain by retaining interior warmth and transmitting solar energy from outside. Thermo spacer bars connect the glazing panes, helping to eliminate cold areas at the edge of the unit, reducing condensation.

Over 20% of heat loss within the home occurs through old or outdated windows and doors, resulting in expensive home heating bills. Weathermaster products are thermally efficient by design; by selecting Weathermaster windows you could reduce your home heating bills by up to 40%.


With quality and innovation at the core of our business, we are pleased to offer customers a product range that perfectly complements today's current climate.

Product Peformance

Our Products are manufactured to only the highest quality standards and are backed by an exclusive 15 year performance guarantee.

Multi Chambers

Multi chambers within the profile help eliminate heat loss through the frame; keeping your home warm and reducing waste energy.

Energy Perfomance

Our double glazed windows feature heat reflecting glass and 'A' ratings as standard on all casement-style windows.

Concealed Gaskets

Window frames feature concealed glazing gaskets for zero sightlines; ensuring that the gasket rubber does not obstruct the glazing area.

Positive Drainage

Inbuilt channels within the profile system provides enhanced weather performance; ensuring your frames remain fully sealed and watertight.

Frame Finish

All frames feature 100% lead-free, virgin skin surfaces. Frames are also fully welded for enhanced mechanical performance and aesthetic appeal.


U-values take into account all components of the window including the frame, glass and spacer bar; therefore the lower the U-value, the more energy efficient the window.

Our double glazed windows offer U-values of 1.4W/m2K as standard ('A' rating), with the option to reduce the overall U-value to 1.2W/m2K. By selecting the triple glazed windows, featuring Soft Coat Xtra and Argon gas, you can further reduce the whole window U-value to only 0.8W/m2K.

Weathermaster windows are independently tested and certified, and exceed building regulation requirements for energy efficiency, which can be benficial if renting or selling a property.
