Bi folding windows create a dramatic, uninterrupted opening that transforms the way your home connects with the outdoors. With configurations from two up to eight sashes, they offer remarkable flexibility — from a simple window to a full panoramic opening that elevates any living space.
Crafted with precision engineered Siegenia hardware ( www.siegenia.com ) from Germany, our bi folding systems deliver exceptional strength and smooth performance. Each sash can carry up to 80 kg, yet glides effortlessly on large ball bearing rollers that ensure quiet, refined movement. The premium Titanium Silver track finish enhances durability and maintains its sleek appearance over time.
Because PVC U profiles are beautifully substantial, we recommend a minimum sash width of 600 mm to maintain elegant proportions and generous glass areas.
Bi folding windows are a premium choice due to their specialised hardware and engineering. If a full opening isn’t essential, stack windows offer a sophisticated alternative — providing up to two thirds opening width with a more economical configuration.
