Innovating aluminium products for tomorrow
Duration Windows is transforming the aluminium sector with products that are helping installers to redefine modern spaces in the home
The aluminium window and door industry is experiencing a transformative shift, driven by changing consumer demands in home design, sustainability, and security. Today’s homeowners seek energy efficiency, seamless indoor-outdoor integration, and a minimalist aesthetic that pairs expansive glass panels with slim, unobtrusive frames. Duration Windows, a family-run UK enterprise, is at the forefront of this evolution, leading with a combination of innovation, quality, and exceptional customer service.
Modern consumers want more from their windows and doors than mere functionality—they desire products that elevate their living environments. Designs that dissolve the boundaries between indoors and outdoors are increasingly popular, offering unobstructed views and a sense of spaciousness. To satisfy this trend, manufacturers have refined frame profiles to maximize sightlines, creating a visual flow that connects interiors with the outdoors.
Critical consideration
Sustainability has also become a critical consideration as homeowners seek energy-efficient solutions that reduce heating and cooling costs. Duration Windows has risen to the occasion with two flagship products: the Durafold 1000 Slimline Bi-fold door and the Premium Slider patio door. The Durafold 1000, launched in 2021, features a streamlined beading system, narrow sightlines, and a thermally efficient aluminium profile. The Premium Slider, introduced in 2023, accommodates glass panels up to three meters wide, combining expansive views with high energy performance and advanced security.
One of Duration Windows’ distinctive advantages is its comprehensive product range, creating a “one-stop shop” for installers and homeowners alike. This extensive selection spans windows, doors, roofs, secondary glazing, commercial, bi-folding doors, sliding doors, and the popular Heritage Range.
The company’s family-oriented ethos enhances its business approach. Duration nurtures a supportive workplace, retaining a team of long-standing employees who embody the company’s dedication to quality and attentive customer care. This commitment to personal service extends to customers, who are treated as members of an extended family, receiving tailored solutions and expert guidance at every stage of the process. The company’s culture has cultivated a loyal workforce that consistently drives Duration’s success and reputation for reliability.
Commitment to quality
Quality is non-negotiable in the aluminium windows and doors sector, and Duration Windows has built a strong reputation for durability and reliability. Each product combines skilled craftsmanship with cutting-edge technology and comes with a 10-year guarantee, providing customers with long-term assurance.
As a UK-based manufacturer, Duration upholds stringent quality standards and maintains multiple industry accreditations, including certifications from the British Fenestration Rating Council (BFRC) and BSI’s Kitemark. These accolades underscore the company’s adherence to both environmental and safety requirements. Duration’s status as an approved supplier to the Ministry of Justice further highlights its commitment to excellence and trustworthiness.
Expanded Offerings for Installers
Installers have shown a strong preference for Duration’s bi-fold doors, Heritage Range, and secondary glazing solutions. Duration’s bi-fold doors cater to the trend toward open-plan living, facilitating easy access between indoor and outdoor spaces.
Duration’s secondary glazing solutions, pioneered nearly 40 years ago, remain a valuable option for improving thermal insulation and soundproofing, especially in listed buildings where alterations to the exterior are restricted. This option allows installers to offer clients energy-efficient upgrades while preserving the building’s original appearance.
The Heritage Range, in particular, captures the appeal of classic steel windows but incorporates modernized thermal and security features, making it ideal for period properties and conservation areas. To stay ahead of evolving industry trends, Duration has expanded its Heritage Range offerings. A notable addition is a line of Internal Screens, available in multiple configurations, including single and double doors, fixed screens, and sliding options. These screens are ideal for creating internal partitions in homes or offices and come in over 200 RAL colours and several glass finishes, enabling customization to suit diverse aesthetic and practical requirements.
Further bolstering its Heritage Range, Duration has launched a 25mm thermally broken transom—the slimmest on the market—to meet demand for authentic steel-look windows that also deliver on energy efficiency.
Support for Installer Partners
In addition to its innovative products, Duration Windows provides substantial support to its installer network. From marketing assistance to technical support, Duration equips its partners for success. Installers benefit from unbranded marketing materials, product samples, and a 3D product configurator, all designed to showcase Duration’s range effectively. Additionally, Duration’s showroom offers a professional space where installers can guide clients through the available options.
The technical team at Duration further supports installers with CAD drawings, detailed product specifications, and user documentation, instilling confidence in project execution. The company also facilitates customer referrals, connecting homeowners with trusted installers to strengthen its partner network.
A Vision for the Future of Aluminium Windows and Doors
Duration has solidified its reputation as a leading force in the sector by remaining responsive to industry trends and supporting its installer network by being awarded Aluminium Fabricator of the Year at the National Fenestration Awards, voted for by industry peers. With ongoing expansion and innovation, Duration remains committed to setting new benchmarks in design, sustainability, and service for the future of the aluminium windows and doors industry.
