Advance Door is the entry specification flush door in the Advance Door range, manufactured with 100% imported pine frames for interior openings in residential and commercial projects. It is built as a 9 ply flush door on 3-core construction with shock resistance design, and bonded using HVRT for strong bonding through the core.
High Viscous Resin Technology drives resin deep inside the core, while GLP protection is applied at the glue lines, where a flush door usually separates first. The timber is kiln dried and humidity balance tested for no deformation, and lock rail reinforcement runs on both sides of the shutter.
Under test condition the shutter clears more than 8 end immersion cycles, passes MDST multi drop slam testing and is rated resistant to heavy impact. Advance Door carries a 12 year warranty, with Silver, Gold and Tungsten available for treated and calibrated requirements.
Why Advance Door Performs Differently?
9 Ply Flush Door
Nine-layer Shutter Build
Nine bonded layers spread load across the full face of the shutter, which keeps the surface flat under laminate, veneer or paint.
3-Core Construction
Shock Resistance Design
Three structural cores with an intermediate panel layer, arranged so impact energy is absorbed through the build instead of landing on one face.
100% Imported Pine Frames
Consistent Softwood Framing
Imported pine frames give uniform density and straight grain, so screw hold at hinge and lock positions stays predictable across every shutter.
HVRT
High Viscosity Resin Technology
High viscosity resin penetrates deep inside the core for strong bonding, rather than sitting near the surface where a bond line fails first.
GLP
Glue Line Protection
Protective treatment is applied at the glue lines, which are the layer interfaces where separation and infestation begin in a flush door.
Lock Rail Both Sides
Reinforced on Both Faces
Continuous lock rail on both sides lets the fitter set the lock, handle or latch on either face with no site modification to the shutter.
Core-1, Panel-1, Core-2
Defined Internal Stack
The internal sequence is fixed, so every shutter is built to the same arrangement of core, panel and core instead of varying between batches.
Kiln Dried Timber
Humidity Balance Tested
Timber is kiln dried and humidity balance tested for no deformation, which controls the moisture movement that warps and bows an untreated shutter.
End Immersion Test
More than 8 Cycles
Edges are immersion cycle tested more than eight times using 710 grade resin, under test condition, to check the bond that carries the most stress.
MDST
Multi Drop Slam Tested
Slam tested under test condition, because repeated slamming loosens joints and lock rails long before the face of a door shows any wear.
Shock Resistant
Rated for Heavy Impact
Rated resistant to heavy impact, which matters on doors that take trolleys, furniture and daily traffic against the same points.
12 Year
Warranty
Advance Door is backed by a 12 year warranty against manufacturing defects, subject to correct installation, handling and maintenance.
Recommended Applications for Advance Door
Bedroom Doors
3-core construction and kiln dried pine frames keep a single-leaf shutter flat against the frame rebate, where any bow or twist shows immediately.
Interior Room Doors
Suited to room-to-room openings in dry interior areas. Lock rail on both sides means the handle can be set on either face at the fitting stage.
Office Cabin Doors
MDST slam testing and heavy impact resistance suit cabin doors that open and close continuously through a working day.
Hotel and Guest Room Doors
A fixed nine-layer build and a defined internal stack keep finished shutters consistent across a full floor of identical openings.
Residential Project Openings
The 12 year warranty and repeatable construction suit builders specifying one door type across multiple units in a single project.
Laminate and Veneer Finishing
The flat nine-layer face takes laminate, veneer or paint without the core structure telegraphing through the finished surface.
For bathrooms, utility areas and other moisture-exposed openings, specify Advance Door Gold or Advance Door Tungsten, which are 100% boiling water proof. For fire retardant requirements, specify Advance Door Tungsten.

Frequently Asked Questions About Advance Door
What is Advance Door used for?
Advance Door is used for bedroom doors, interior room doors, office cabin doors and residential project openings in dry areas. Its 3-core construction, kiln dried imported pine frames and both-side lock rail suit single-leaf internal openings that take daily use.
How many layers does Advance Door have?
Advance Door is a 9 ply flush door built on 3-core construction, with an internal stack of Core-1, Panel-1 and Core-2. Nine bonded layers spread load across the face, which keeps the shutter flat under laminate, veneer or paint.
What is HVRT in Advance Door?
HVRT is High Viscous Resin Technology. The high viscosity resin penetrates deep inside the core for strong bonding rather than staying near the surface, where the bond line is usually the first part of a flush door to give way.
Is Advance Door suitable for bathrooms and kitchens?
Advance Door is built for interior dry-area openings. For bathrooms, utility areas and other moisture-exposed positions, specify Advance Door Gold or Advance Door Tungsten, which are 100% boiling water proof. Advance Door Tungsten is also 100% fire retardant.
What warranty does Advance Door carry?
Advance Door carries a 12 year warranty against manufacturing defects, subject to correct installation and handling. Within the range, Advance Door Silver carries 15 years, Advance Door Gold carries 35 years and Advance Door Tungsten carries a lifetime warranty.
How is Advance Door different from Advance Door Silver?
Silver adds FBTT treatment across 7 layers, VPT vacuum pressure treatment, HEXAPRO four times pressing and 100% calibration, and lifts the warranty from 12 to 15 years. Both share 9 ply construction, 3-core build, imported pine frames and HVRT bonding.
