Hume Doors
Door Construction & Core Types Explained
The core is what decides how a door performs, its weight, how solid it feels, how well it holds sound and heat, and whether it suits a wet area or a bushfire opening. Every Hume door is built to one of the construction types below. Here is what each one is and how it performs. Tap any diagram to see the cross-section full size.
Hollow & lightweight cores
A honeycomb core between two skins keeps the door light and economical. Ideal for internal openings where weight and cost matter more than mass or acoustics.
Honeycomb Core (Hollow Core H1)
A kraft-paper honeycomb core between two primed skins. The lightest, most economical construction, well suited to low-traffic internal openings like wardrobes, pantries and linen cupboards.
Honeycomb Core (Hollowcore X1)
A honeycomb core built for external glazed openings, paired with a durable face so the light construction still stands up to an entry environment.
Honeycomb Core (Hollowcore SG) 6mm Skin
A honeycomb core with thicker 6mm skins for noticeably better impact resistance and a more solid feel than a standard hollow core, while staying relatively light.
Honeycomb Core Large Cell (Moulded Panel)
A large-cell honeycomb core used behind a pressed moulded-panel face, giving the traditional panel look at a light hollow-core weight.
Frontier Premium Hollow Core (SG)
The premium hollow core used in the Frontier barn door range, light enough to slide easily on barn-door hardware while holding a flat, stable face.
Solid & substantial cores
A solid particleboard, MDF or timber core makes the door heavier, quieter and more stable, the right choice for a substantial feel, better acoustics, or wet and high-use areas.
Solicore Particleboard Core (SCX1)
A solid, water-resistant particleboard core. Heavier and quieter than a hollow core, with better acoustic and thermal performance, a solid-feeling door for main living areas.
Solicore Particleboard Core (SCX1 Moulded Panel)
The solicore particleboard core behind a moulded-panel face, the pressed-panel look with the weight and quiet of a solid door.
Solicore Particleboard Core (SCX1 PCMDF)
A solicore particleboard core with a primecoat MDF face, ready to paint, solid and stable with a smooth, paint-grade finish.
Solid HMR MDF Core (DB)
A solid high-moisture-resistant MDF core. Dense and dimensionally stable, suited to heavier or high-use openings and areas with some moisture exposure.
Solid HMR MDF Core (HV)
A solid HMR MDF core in the heavier-duty (HV) build for the most substantial, stable doors.
Solid Timber Pine Core (STPC Blockboard)
A solid timber pine blockboard core, a fully solid door with real timber substance behind the face.
Frontier Ultimate Solid Infill Core
A solid infill core for the Frontier Ultimate barn door, adding weight and a more solid feel than the Premium hollow-core version.
Engineered, panelled & specialty
Purpose-built constructions for glazed and panelled doors, and the internal reinforcement that supports locks and hardware.
Engineered Joinery
Laminated timber stiles and rails framing a panel or glass, finished in a real timber veneer or a paint-grade face, the construction behind the joinery entrance and internal ranges.
Hampton Construction
The construction behind the Hampton range, a solid infill with a pressed panel profile and a primed face, ready to paint.
Door Stiffener (HMR MDF)
A moisture-resistant MDF stiffener built into the lock area of hollow-core doors, giving hardware a solid section to fix into.
Fire & bushfire rated
Certified constructions for openings that have to meet a bushfire or fire rating.
BAL 40 Construction
A bushfire-resisting construction certified to BAL 40, the highest of the standard Bushfire Attack Levels for entrance doors. Always confirm the required BAL rating for your site with your certifier.
