25mm Aluminium Venetian Blinds -- Made to Measure in South Africa
Custom Blinds 25mm aluminium venetian blinds are made-to-order window coverings featuring slim aluminium slats that tilt to give you precise control over light, airflow, and privacy. Each blind is custom manufactured in South Africa to your exact window measurements, with a typical production time of approximately 5 working days and free nationwide delivery. The 25mm slat width creates a sleek, contemporary profile suited to modern interiors and smaller windows.
Who 25mm Aluminium Venetian Blinds Are For
These blinds are the go-to choice for bathrooms, kitchens, laundry rooms, offices, and any space where moisture or humidity is a concern. Aluminium will not warp, rust, or deteriorate in steam -- making it the practical choice for coastal homes in Durban, Cape Town, and the Garden Route. They suit homeowners wanting a clean modern look, offices needing glare control, and commercial spaces requiring durable, low-maintenance window coverings.
How They Work
Each blind consists of horizontal 25mm aluminium slats suspended on ladder cord and controlled by a tilt wand and lift cord. Tilting the wand angles the slats to let in as much or as little light as you want. Pulling the lift cord raises the entire blind for a clear window. The aluminium construction means the slats stay straight and true -- no bowing, no warping, even after years of daily use.

Comparing 25mm Aluminium to Other Venetian Blinds
Custom Blinds offers several venetian options. 25mm aluminium suits modern interiors and smaller windows with its sleek profile. 50mm aluminium provides a bolder architectural look for larger windows. Aluwood venetians combine aluminium durability with a realistic wood grain finish. Plaswood venetians offer wood aesthetics with full moisture resistance. Real wooden venetians deliver authentic timber warmth for dry rooms. Each serves a different purpose -- 25mm aluminium is the most affordable and practical for wet areas.
Installation
Standard installation uses two wall or ceiling brackets and takes approximately 15 minutes per window with a drill and spirit level. A step-by-step measuring guide is available at shop.customblinds.co.za to ensure accurate ordering. Garden Route customers in Knysna, George, Plettenberg Bay, Sedgefield, Mossel Bay, and Wilderness can book professional installation with Duncan Kane, the company founder.
