Bi-Folding Doors: Winter Warmth and Summer Openness

After two harsh winters, UK homeowners with Apropos bi-folding doors stayed snug. With unpredictable weather ahead, these doors prove their worth year-round.

Design and Thermal Performance

• Bespoke design for every property.
• Sweeping profiles, minimal frames maximize light, even on dark winter days.
• Advanced double glazing: centre-pane U-value better than 1.2 W/m²K.
• Result: Large glass areas that retain heat exceptionally well—no cold drafts, no "Jack Frost" pinch.

Dual Function

• Summer: Fully open, merging interior with garden.
• Winter: Closed, they act as huge picture frames, turning the garden into a cosy backdrop while flooding the room with natural light.

Why They've Replaced Patio Doors

Contemporary aesthetics, superior thermal efficiency, and the ability to open entire walls make bi-folds the preferred choice for rear and side elevations.
