Energy savings
Reducing heat loss through the glazing and frame can lower space-heating demand and improve whole-building efficiency.
WINDOW SYSTEMS
Three materials. One performance-led approach.
We select window systems around the building, the energy target, the architectural intent and the budget — not around a single manufacturer.
TIMBER WINDOWS • HERITAGE SASH
Heritage sash windows that honour the original architecture.
Our timber heritage sash windows are designed for period properties, conservation areas and listed buildings where the appearance of the original windows is an important part of the building’s character.
Traditional details such as putty-style glazing, ovolo mouldings and period-inspired profiles help preserve the proportions and visual character expected in heritage settings. Each specification can be tailored to the property, with careful attention to the original design, sightlines and finish. We take a considered approach to detailing, smooth operation and accurate fitting, helping balance traditional appearance with the practical requirements of a modern home.
Modern energy efficiency within a traditional frame.
Where planning conditions and the building’s character allow, heritage sash windows can be specified with slim double glazing to improve thermal comfort compared with original single glazing.
Performance depends on window design, glazing and installation. Carefully considered draught-proofing and seals can reduce unwanted air movement while retaining traditional proportions. Ventilation and any enhanced glazing options should be agreed against the property’s conservation requirements and project specification.
Slim double glazingWhere conservation and planning requirements permit, slim double-glazed units can improve thermal comfort compared with original single glazing.
Draught-proofingCarefully selected seals and draught-proofing can help limit unwanted air movement while keeping the traditional appearance of the window.
Conservation-conscious designGlazing bars, mouldings, sightlines and finishes can be considered to help respect the character of period properties and local requirements.
Careful fittingAccurate surveying, careful installation and smooth operation are central to a good result in a heritage property.
ALUMINIUM WINDOWS
Slim, strong and made for contemporary architecture.
Modern thermally broken aluminium windows combine strength with slim sightlines, making them ideal where generous glass areas, crisp detailing and long-term durability are priorities.
The inherent strength of aluminium allows larger openings and narrower-looking frames than many conventional alternatives. High-quality powder-coated finishes resist fading, warping and routine weather exposure with very little upkeep.
Slim sightlinesMore glass and less visible frame can create brighter interiors and stronger connections to the outside.
Thermally brokenInsulating sections separate the inner and outer aluminium faces to reduce heat transfer through the frame.
DurabilityAluminium does not rot and is highly resistant to distortion, making it suitable for demanding residential and commercial applications.
Design choiceAvailable in a broad range of powder-coated colours, opening styles and large-format configurations.
FIBREGLASS COMPOSITE WINDOWS ↗
High insulation with advanced composite reinforcement.
Our composite window options use advanced reinforcement technology to deliver strong thermal performance without relying on heavy conventional steel reinforcement throughout the frame.
This helps create slimmer, more efficient profiles with excellent dimensional stability, while supporting larger elements and highly insulated glazing packages. Selected systems are available with whole-window U-values in the region of 0.7 W/m²K, subject to final size, glazing and configuration.
Energy efficientOptimised frame construction and deep glazing platforms support very low heat loss and triple-glazed configurations.
Strong & stableComposite reinforcement can reduce the need for conventional steel while retaining the stiffness required for larger window and door elements.
Lower-impact thinkingModern profile manufacture increasingly incorporates recycled content, closed-loop recycling and renewable-energy production.
Contemporary designClean profiles, flush aesthetics and modern finishes suit both new-build and refurbishment projects.
WHY HIGH-PERFORMANCE WINDOWS?
More than a lower U-value.
Comfort
Warmer internal surface temperatures and better airtightness help reduce cold downdraughts and uneven room temperatures.
Quieter interiors
Appropriate glazing and well-sealed frames can significantly improve acoustic comfort, particularly in busy urban locations.
Lower carbon impact
Better fabric performance reduces operational energy demand, while durable and recyclable materials can improve whole-life performance.
