Cavity Sliders
Why Choose a Cavity Slider?
A cavity slider is a type of sliding door system where the door disappears into a wall cavity when opened. Unlike traditional barn doors that slide along the outside of a wall, cavity sliders are built into the wall itself, offering a sleek and space-saving solution. In New Zealand homes and commercial spaces, cavity sliders are especially popular for:
-
Maximising space in tight areas like bathrooms, laundries, and wardrobes
-
Creating clean, modern lines in architectural designs
-
Improving accessibility with smooth, unobtrusive operation
-
Smooth operation - high-quality track systems ensure quiet, effortless sliding
-
Customisable sizes & styles - available in single or double configurations, and compatible with a wide range of door finishes, from timber to glass
Cavity Sliders are ideal for both new builds and renovations where space, efficiency and aesthetics are key.

Optional features for cavity sliders
Soft Close & Open Mechanism
The door slows down gently and closes quietly when it’s about to shut, rather than slamming. It typically uses a damper and spring system to absorb the momentum of the door and pull it closed smoothly.
Key benefits:
-
Prevents slamming - reduces noise and wear on the door and frame
-
Improves safety – minimizes the risk of fingers getting caught
-
Enhances durability – protects the door hardware from impact damage
-
Adds a premium feel – makes the door operation smoother and more refined
Self-Closing Cavity Slider
This is a type of sliding door that automatically closes itself after being opened. It slides into a wall cavity (like a standard cavity slider).
Key benefits:
-
Convenience - the door closes automatically without needing to be pushed shut; great for busy households, offices, or when your hands are full
-
Improved privacy - ensures the door is always closed after use, which is useful in bathrooms, bedrooms, or meeting rooms
-
Energy efficiency - helps maintain room temperature by preventing doors from being left open, which is especially helpful in air-conditioned or heated spaces
-
Safety & hygiene - reduces the need to touch the door, which is beneficial in healthcare or food prep areas
-
Aesthetic & functional flow - keeps spaces looking tidy and ensures doors don’t remain awkwardly open or half-closed
Acoustic Seals
Acoustic seals for cavity sliders are specialised components designed to reduce sound transmission through and around sliding doors that disappear into wall cavities. They're especially useful in environments where privacy, noise control, or soundproofing is important, like bedrooms, offices, meeting rooms, or media rooms.
Key benefits:
-
Minimise sound leakage - they seal the gaps around the door
-
Improve acoustic performance - they can significantly increase the Rw (Weighted Sound Reduction Index) rating of the door system, helping to block airborne noise
-
Enhance privacy - ideal for rooms where conversations or activities should remain private, such as therapy rooms, boardrooms, or bedrooms
-
Complement soft-close systems - acoustic seals often work well alongside soft-close mechanisms, maintaining a quiet and smooth user experience
-
Help with insulation - while their primary purpose is soundproofing, they can also help with thermal insulation and draft reduction
Full-Height or Floor-to-Ceiling Systems
These systems allow sliding doors to span from floor to ceiling, creating a seamless, modern look with no visible head tracks or trims. They are ideal for high-end residential, commercial, and architectural projects.
