FAQs
How do vertical aluminium sliding windows work?
Vertical sliding windows operate on a smooth sliding system where the upper or lower sash slides up or down within the frame. You can open the top, the bottom, or both sections independently to control airflow as needed.
What sizes are available for aluminium vertical sliding windows?
Vertical Sliding Windows are only available in standard sizes. Need something custom? We offer a range of alternative window solutions—contact us for a free measurement and quote.
Do vertical sliding windows protrude on the outside?
No. One of the key advantages of aluminium vertical sliding windows is that no panels protrude on the exterior of the building. This makes them an excellent choice for areas where external clearance is limited or where a clean exterior appearance is important.
Are vertical sliding windows suitable for upper-storey installations?
Yes, aluminium vertical sliding windows are ideal for upper floors. The sliding mechanism means the window opens within its own frame, with nothing protruding outward – making them safe and practical for any storey.
What aluminium vertical sliding window design options are available?
Our aluminium sliding windows are available in a range of sizes and popular powder-coated colours. Standard colours include White, Bronze, Charcoal, Black, and Silver. A full range of non-standard and custom colours including wood-look finishes are also available.
Are vertical sliding windows weatherproof?
Yes. Sequ-Door’s vertical sliding windows are made for weatherproof external use. They are designed to maintain performance in rain, wind, and the temperature fluctuations typical of the South African climate.
How do I maintain aluminium sliding windows?
Our aluminium sliding windows require very little maintenance. Clean the frames periodically with a non-abrasive cleaner, and ensure the sliding tracks are free of dust and debris for smooth operation. The powder-coated finish offers excellent durability.
Can vertical sliding windows be fitted with security features?
Yes. We recommend pairing vertical aluminium sliding windows with complementary burglar bars, security fixtures or shutters for enhanced security, particularly on ground-floor or accessible installations.
