Made for Trade: Vertical Sliding Windows with Flexible Lead Times and Tailored Options
The Trade Advantage: Lead Times You Can Count On
Installers and specifiers working to tight timelines need suppliers who deliver – not excuses. Mercury Glazing’s trade vertical sliding windows are manufactured entirely in-house, giving you complete confidence in both product quality and delivery turnaround. With a standard lead time of just two weeks, they’re a smart choice for time-sensitive contracts, restricted access sites, or volume-based projects.
To meet rising demand from trade customers, Mercury has expanded its factory operations – a strategic move that increases output without compromising on craftsmanship. Unlike mass producers or third-party drop shippers, Mercury oversees every stage of production, offering more accurate lead times, fewer delays, and greater control.
This commitment to service-led manufacturing means your schedule stays on track, whether you’re sourcing five units or managing a full-site rollout. You can explore the full trade offering here via Mercury’s trade vertical sliding sash windows page.
“In this industry, timing is everything. That’s why we’ve invested heavily in production capacity to offer reliable lead times without cutting corners. It’s not about churning out volume – it’s about doing things properly and supporting our trade customers every step of the way.” – Steven Cross, Director
The Craftsman Range: Timber-Look Without Timber Hassle
For heritage-sensitive projects, Mercury’s Craftsman vertical sliding sash windows offer the authentic look of traditional timber without the ongoing maintenance. Designed to meet the aesthetic demands of conservation zones, this slimline range replicates original Georgian and Victorian profiles while delivering excellent energy performance and modern functionality.
Approved for use in listed settings such as the Royal Crescent in Bath, the Craftsman sash is a proven solution for installers working on sensitive sites. From deep bottom rails to putty-line detailing, it’s built to meet planning expectations where authenticity matters most. Unlike off-the-shelf alternatives, these units are crafted in-house for tighter control over quality and consistency.
You can explore the Craftsman collection in more detail via Mercury’s dedicated product page: Craftsman sash windows.
PVC-U Vertical Sliders: Performance Meets Affordability
For trade customers balancing cost and compliance, Mercury’s PVC-U vertical sliding sash windows provide a reliable, high-performance alternative to timber. With A-rated energy efficiency, run-through horns, and a wide choice of foiled finishes, they offer a traditional appearance with modern-day practicality.
These PVC-U sliders are manufactured to the same exacting standards as the aluminium and Craftsman ranges, giving trade customers a robust, versatile option for new-build or refurbishment projects. With slim profiles and authentic detailing, they’re also accepted in many conservation areas, offering a credible solution at a more accessible price point.

Colour and Hardware Options to Suit Every Site
Whether your client is after subtle heritage tones or bold contemporary styling, Mercury’s trade vertical sliding windows are available in a wide selection of RAL colours, foils, and hardware finishes. Georgian bars, run-through horns, and deep bottom rails can all be customised to match regional design expectations or replicate existing units.
Mercury’s in-house production allows for bespoke configuration without the long delays often associated with custom orders. Whether it’s a period restoration or a prestige new-build, the ability to match design details precisely is a major advantage for installers looking to secure planning approval and client satisfaction.
Built Around Trade: Total Flexibility Without Compromise
Mercury’s service model has always been built around the needs of trade professionals. Whether you’re managing a full property renovation or replacing a single unit, the flexibility to customise every element – from sash style and glazing to finish and delivery – makes a real difference.
Unlike many vertical sliding sash suppliers who buy in or drop ship from third-party manufacturers, Mercury fabricates every unit in-house. This allows trade customers to choose from a wide selection of styles and configurations without losing time to third-party lead times or unclear specifications. You get a direct line to production, technical support, and estimating assistance from day one.
If you’re specifying trade vertical sliding windows for a tight deadline, conservation zone, or listed building retrofit, this kind of responsiveness matters. Mercury’s full trade support offer is detailed here: Mercury Trade Sashes
Why Trade Customers Trust Mercury
Mercury has always been a trusted name in the trade because they understand the value of partnership. It’s not just about delivering a box of frames – it’s about supporting every part of your process, from initial quote through to final installation. That includes helping you get the right specs for planning officers, offering technical insight where needed, and making sure your delivery arrives on time and in full.
The in-house manufacturing model means you’re not left chasing after missing parts or fielding awkward questions from clients. Mercury’s control over quality, compliance, and aesthetics ensures you can install with confidence, especially when dealing with listed buildings or historic sites.
In fact, Historic England outlines the importance of careful planning and specification when retrofitting windows in period buildings – especially where heritage character must be preserved alongside improved performance. Mercury’s product approach aligns directly with this guidance, offering windows that meet both aesthetic and energy efficiency goals.
Supporting a Growing Market with Trade-First Insight
The demand for traditional sash-style products remains strong, with conservation-led planning rules and design-conscious homeowners driving long-term growth. According to a recent market report on windows and doors in Europe, heritage-style window systems – particularly those with improved thermal performance – are a growing priority for both developers and contractors.
Mercury has responded not just by expanding capacity but by refining its offer to support the evolving needs of trade professionals. That includes ongoing investment in manufacturing, expansion of the Craftsman range, and maintaining clear, realistic lead times even in high-pressure build environments.
If your customers expect style, performance, and precision, Mercury Glazing delivers – without compromise. Learn more about the vertical sliding window options available to trade customers and see why installers nationwide choose Mercury for heritage window supply.
