The Superior Doors RibCore hollow core interior door range represents industry leading strength and durability with a focus on innovation and attention to detail to produce a truly Superior Door. They are thicker, stronger, offer better impact resistance, greater thermal insulation and are more durable than any other standard hollow core door on the market.
Our standard RibCore achieves about 42% glue adhesion between the core and the door skin while cheaper traditional honey comb paper core used by most other manufacturers has about 4% glued contact between door skin and core. Add together the additional strength obtained using thicker and wider timber and the fact that RibCore has more than 10 times glued adhesion between skin and core and you have one very superior internal door. What this means is simple, a strong door that can easily absorb what life throws at it without popping, bending or bowing. That's what makes a Superior Door, superior.
Standard Cores Comparison
Hover over the plus signs to experience the difference in glue contact area between Superior Doors standard RibCore™ or Solid EPS Core and other traditional Honeycomb Paper Core doors. Greater glue contact equals a stronger more resilient door that won't de-laminate after impact.

Skin Options
At Superior Doors we offer a range of skin thicknesses to suit most situations and needs. Thicker door skins increase strength and durability, allow for deeper more substantial grooving and reduce component show through for a flatter higher quality finish.
UV Pre Primed Skins
The use of UV primer represent additional benefits to the home owner and the environment they live in. UV primer is both moisture and solvent resistant, harder and more scratch resistant and offers greater fire resistance than normal door priming solutions. In addition to its general resistance it is also formulated to offer optimal adhesion for all main stream finishing coats.
UV primer is also solvent, formaldehyde and V.O.C ( Volatile Organic Compounds ) free. The coating process is energy efficient unlike the heat drying processes used to evaporate water based solutions. UV primer can also be disposed of without additional processing via landfill, incineration or recycled into pulp
