uPVC Sliding and Stacker Doors in Melbourne

The terms are related but distinct. A sliding door typically refers to a 2-panel system where one panel slides across to overlap the other, opening roughly half the total frame width. A stacker door refers to a multi-panel system where all panels stack progressively behind each other at one or both ends of the track, opening the majority or entirety of the frame width. A 4-panel stacker with panels splitting 2+2 can clear almost the full opening. A 6-panel stacker can clear up to 6 metres of wall completely. Both use the same sliding mechanism, the difference is purely in panel count, configuration, and the resulting size of clear opening.

Deceuninck's heavy-duty ball-bearing roller system is specifically engineered to maintain smooth, easy operation through the life of the installation. The Legend Sliding System's 76mm wing profile provides the structural depth to carry the roller system without flex. uPVC frames are dimensionally stable, they don't expand in Melbourne's summer heat or contract in winter cold the way aluminium and timber frames do. A timber or aluminium sliding door that operates perfectly in autumn can bind and drag by the following summer. A Deceuninck uPVC sliding door operates identically regardless of the month, because the frame maintains its geometry across all conditions.

The Legend Sliding System is Deceuninck's high-performance sliding door system, engineered to a specification above the standard sliding range. Its 76mm wing profile with 5 chambers provides the structural depth, thermal performance, and acoustic isolation that narrower sliding door profiles cannot achieve. The system accommodates glass up to 52mm thickness within the sealed unit, allowing acoustic laminated glass combinations that significantly outperform standard double glazing for noise reduction. Aesthetic design and ease of use are its defining features, and it provides high-level protection against Melbourne's extreme hot and cold weather conditions. It represents the balance between energy efficiency and comfortable living.

The Deceuninck sliding system accommodates opening widths up to 6 metres, with up to 6 movable panels arranged in any desired combination. You can choose the number, dimension, and function of each section based on your specific requirements. Systems are available as two, three, or four parts, or more, in a combination of fixed and movable parts. For Melbourne homes and commercial projects requiring openings beyond what a 2 or 3-panel system can address, a 4-panel, 5-panel, or 6-panel stacker configuration makes those widths achievable and practical.

Yes, and the Deceuninck sliding system is designed with security as a core engineering requirement, not an afterthought. Every door in the range features a one-piece multi-point locking system that engages at multiple points along the door simultaneously, effectively secured lock technology with security locking strikers, and easy-to-use locking mechanisms with key and/or lever operators. Solid and substantial components throughout. The uPVC frame provides structural resistance against lateral forced entry loading. Your new Deceuninck sliding door is unequalled in strength and fully guaranteed to perform as well in years to come as it does today.

The Legend Sliding System accommodates glass up to 52mm thickness, a specification that allows sealed unit combinations that standard sliding door profiles cannot carry. Available glass options include standard clear double-glazed units, low-E (low-emissivity) glass for maximum energy efficiency, acoustic laminated glass for noise reduction (particularly relevant for street-facing sliding doors in Melbourne's inner suburbs), toughened safety glass where required, tinted glass for solar control on north and west-facing openings, and obscure glass for privacy where needed. The system offers alternative decoration possibilities, the right glass choice for your situation will be recommended by our team during the free in-home consultation.

Yes, though the sliding and stacker door's natural context is contemporary or post-period architecture. For heritage homes where the brief calls for alfresco access at the rear, sliding doors in cream or woodgrain uPVC finishes can be specified to minimise their contrast with the period character of the building. The rear elevation of Melbourne's inner-suburban terrace homes, often heavily modified in the 20th century, regularly accommodates sliding door systems that sit sympathetically within the modified portion of the property without affecting the heritage-significant front elevation. Our team has experience across Melbourne's heritage precincts and can advise on the right approach for your specific property.

The cost depends on the system width, panel count, glass specification, colour, and installation conditions. As a practical guide, a standard 2-panel uPVC sliding door with double glazing typically ranges from $2,800–$4,500 installed depending on dimensions. A 4-panel stacker system for a wider opening ranges from $5,500–$8,500 installed. A 6-panel system at maximum width will be priced accordingly. The most accurate pricing for your project requires a free in-home measure, our team will assess your opening, recommend the right configuration, and provide a fully itemised quote with complete transparency.
