Trade Aluminium Windows: The Installer’s Guide

September 15, 2026

Expanding your product catalogue with trade aluminium windows is one of the most effective ways to capture high-value residential and commercial contracts. Property owners increasingly favour slim sightlines and modern aesthetics, moving beyond traditional timber and uPVC windows. For installation businesses looking to scale, partnering with a dedicated fabricator provides a direct route into profitable markets.

Established in 2008, Dekko Window Systems operates a 55,000-square-foot manufacturing facility in Lancashire, supplying high-grade fenestration products to installers across the UK.

Expanding Your Portfolio With Metal Systems

Modern consumers and property developers frequently request metal window solutions due to their clean lines and durability. Adding trade aluminium windows to your business offering allows you to pitch for contemporary new builds, architectural extensions, and upscale domestic renovations.

While traditional wood windows require ongoing maintenance, and standard uPVC windows can sometimes lack the slender profile desired for minimalist architecture, aluminium frames bridge the gap perfectly. They provide exceptional structural strength while supporting large panes of glass that maximise natural light inside any room.

Precision-Engineered Aluminium Solutions

Dekko manufactures an extensive range of aluminium fenestration products engineered for performance and visual appeal. Fabricated using robust aluminium profiles, each window frame is built to withstand daily operational stress while maintaining smooth functionality.

The inherent rigidity of aluminium allows for slim sightlines that cannot be achieved with alternative framing materials. Whether you are replacing old wooden windows or installing profiles on a commercial building, these systems deliver long-lasting reliability and require minimal upkeep for the end user.

Customisation and Colour Options

Every project has specific design criteria, which is why customisation remains a core focus of the Dekko range. Installers can access a choice of 200 RAL colours, enabling precise matching for contemporary grey schemes, striking black frames, or bespoke architectural aesthetics.

Beyond colour choices, specifiers can select double or triple glazing options configured to meet exact project demands.This level of design flexibility ensures your business can cater to homeowners, housing developers, and commercial clients seeking tailored solutions.

Thermal Performance and Security Standards

Meeting current building regulations requires fenestration that minimises heat transfer and combats rising energy bills. Dekko aluminium windows feature advanced thermal breaks engineered into the profile core. These thermal breaks significantly reduce heat loss, achieving low U-values down to 1.1 W/m²K to deliver outstanding energy efficiency.

Alongside thermal performance, security is built into every assembly. Multi-point locking mechanisms, robust hardware, and secure glazing beads protect properties against forced entry, giving your clients complete peace of mind.

Streamlined Distribution and Logistics

Project timelines rely heavily on predictable supply chains. Dekko operates a reliable nationwide delivery service, ensuring trade orders arrive on schedule.

Manufacturing all aluminium products in-house allows the team to maintain strict quality control at every stage of production. Installers also benefit from dedicated trade counters, including locations in the North of England and the South, providing convenient access to hardware, supplies, and expert technical advice.

Unlocking Trade Accounts and Support

Partnering with Dekko gives installation companies access to competitive trade pricing, comprehensive marketing support, and industry expertise. Setting up a trade account is straightforward, opening the door to dedicated account management and resources designed to help your installation business secure more contracts.
