FAQ
Q: Are your aluminium sliding sash windows approved for use in conservation areas?
A: Yes. Our heritage line is specifically designed with slim profiles, traditional mechanical joints, and putty-line aesthetics to mimic timber. However, as local planning authority guidelines vary, we always recommend submitting our provided CAD cross-sections to the local conservation officer for final approval.
Q: What is the standard lead time for B2B commercial orders?
A: For standard colors (White, Anthracite Grey, Black), our manufacturing lead time is typically 4 to 6 weeks. For custom RAL colors or dual-color extrusions, please allow 6 to 8 weeks. We will provide a firm delivery schedule upon quoting your specific project.
Q: Do these windows feature a tilt function for easy cleaning?
A: Yes, both the top and bottom sashes are equipped with concealed tilt restrictors. This allows the sashes to tilt inwards, enabling safe and easy cleaning of the exterior glass from the inside-a crucial safety and maintenance feature for multi-story developments.
Q: Can you match existing custom colors for historical renovations?
A: Absolutely. We offer marine-grade powder coating in any RAL color. We can also provide a dual-color finish (e.g., Anthracite Grey exterior with a Traffic White interior) so the external facade matches the building while the interior suits modern decor.
Q: How do these compare to uPVC sash windows in terms of cost and lifespan?
A: While the initial capital expenditure for aluminium is higher than standard uPVC, the lifecycle cost is significantly lower. Aluminium boasts a lifespan of 40+ years without warping, discoloring, or degrading under UV exposure, making it a superior investment for high-end residential and commercial builds.
Q: Do you provide installation services or supply only?
A: We primarily operate on a supply-only basis directly to developers, contractors, and specialized installers. However, we provide comprehensive installation manuals and technical support to ensure your on-site teams can fit the products efficiently.
Q: Can the springs support heavy acoustic or triple glazing?
A: Yes. We use heavy-duty, pre-tensioned spiral balances hidden within the frame. These are calibrated specifically for the weight of your chosen glazing specification, ensuring a smooth, effortless sliding operation even with heavy acoustic or triple-glazed units up to 50kg per sash.
