Core Options:

RibCore

RibCore is Superior Doors’ cost-effective alternative for a durable, thermally insulative and lightweight interior door. RibCore doors have up to 42% glue adhesion between the core and the door skin, while traditional honeycomb paper core - used by most other manufacturers - has about 4% glued contact between the door skin and the core. RibCore is a low VOC option, what this means is simple, a strong door that can easily absorb what life throws at it without delaminating, bending or bowing.

Expanded Polystyrene (EPS) Solid Core

Superior Doors provides the option of a premium High-Density Solid EPS Polystyrene Core, made from fire-resistant EPS. Solid EPS cores offer the best in thermal insulation, providing an R-value that is significantly higher than H1 minimums nationwide. Comprehensive R-Value information may be found in the Superior Doors H1 Guide. Solid EPS Cores have almost 100% glue contact area, giving them resistance to delamination, as well as excellent durability and strength. Superior Doors' Solid EPS cores are certified low VOC, making them an elegant solution for a huge variety of applications.

Moisture Resistant (MR) Particleboard Core

For a door that needs a significant amount of hardware, or improved acoustic performance, a Solid Moisture Resistant (MR) Particleboard core is an excellent option. Superior Doors' Moisture Resistant Particleboard Cores are FSC-certified materials, and are low VOC, making them the perfect option for environmentally forward projects. Solid MR Particleboard cores additionally boast up to 100% glue contact area, giving them resistance to delamination, and enhancing the existing strength of the core. For those who require a door with maximum impact resistance, the MR Particle Board solid core option is the perfect choice. The MR Particle Board Core is more moisture-resistant than standard particle board and is the ultimate core option for strength and durability.

Steel Reinforcement Options

Steel reinforcement is necessary for barn doors, cavity sliders, wardrobes, and surface sliders, as well as in areas where the door may be exposed to an ambient temperature difference, a change in moisture content, or direct sunlight. A single box-cut steel section is typical on the lock block edge for hung doors, to ensure no sagging of the door occurs over time; and two steel sections, one on the lock block edge and one on the other, are considered typical for slider applications. To learn more about what kind of steel reinforcement may suit your needs, visit our website at www.superiordoors.co.nz, or contact the Superior Doors team at [email protected].

Steel Reinforcement is not suitable for a RibCore door, as this is to prevent show-through of the internal components. If steel reinforcement is necessary for your door, EPS Solid Core or MR Particleboard Core are suitable choices.

Grooving Options

Superior Doors offers a broad range of styles of grooved doors, from barn-door look Avon’s to contemporary Coastland’s; there is something to suit every need.

Superior Doors also offer custom grooving, providing unmatched versatility, precision and detail, and the best solution for your innovative, bespoke builds.
