The Aluplast IDEAL 4000 FoldDoor system, with a 70 mm frame depth, supports glazing up to 41 mm thick, providing excellent thermal and acoustic insulation even in large structures. Its five-chamber profile architecture creates an effective thermal barrier—retaining warmth and reducing energy costs. Thanks to the premium folding hardware, door panels slide smoothly and fold compactly into a “concertina” stack. This construction saves space and creates a wide opening suitable for terraces, verandas, or living areas. Two sealing gaskets ensure reliable protection from drafts and weather, with durable seals retaining elasticity over many years. Reinforced galvanized steel inserts give the door structural sturdiness and durability under intensive use. The FoldDoor system maintains good sound insulation, keeping interiors comfortable even during operation. Multi-point locking can be fitted, compatible with modern door fittings. A full range of Aluplast finishes is available—woodgrain, white, anthracite, and Bi-Color options. Ideal for terraces, balconies, winter gardens, commercial spaces, and residential homes, this folding door creates an expansive-open feel that connects spaces seamlessly. Manufactured from eco-friendly PVC resistant to UV light, moisture, and temperature extremes, it's lead-free and built for longevity and safety.

The aluminum folding system with a construction depth of 77 mm (sash) and 86 mm (frame) is designed for infills up to 63 mm thick, including triple-glazed units and insulated panels. A wide, glass fiber-reinforced polyamide thermal break ensures excellent insulation performance, even for large openings. Combined with double or triple sealing gaskets, the system delivers high energy efficiency. Reinforced aluminum profiles allow for large and heavy panels up to 100 kg each, maintaining structural integrity. Precision hardware and durable hinges enable the sashes to fold quietly and smoothly, stacking compactly to maximize open space. Advanced sealing technology blocks drafts, water, and dust. When paired with proper glazing, the system achieves sound insulation up to 42–45 dB. Security fittings up to RC2 class are supported, providing enhanced protection. Minimal visible profile widths contribute to a clean and modern appearance. A wide selection of RAL colors is available, including textured and wood-like finishes. Ideal for residential and commercial applications: terraces, winter gardens, cafés, offices. Aluminum is corrosion-resistant, UV-stable, and fully recyclable, offering long-term durability and environmental sustainability.
