Split-Panel Grey Solid Core Composite Interior Doors Solid Core Door With Frame

The Split-Panel Grey Solid Core Composite Interior Door bridges the gap between traditional panel-door aesthetics and modern material performance. Its two-panel split design—a classic architectural motif dating back centuries—is reimagined through precision HPL lamination, creating distinct panel fields that catch light differently depending on viewing angle. A boutique hotel group in Barcelona recently selected this door for a 120-room property renovation, specifically drawn to the interplay of the split-panel geometry with the hotel's warm LED cove lighting in guest corridors. The anti-fingerprint matte grey surface maintains a pristine appearance despite daily guest traffic, while the soundproof composite core (STC 33–36 dB) ensures corridor noise doesn't intrude into guest rooms. The door arrives as a complete unit with matching frame—factory-machined, test-fitted, and ready for swing-type installation. For project buyers seeking the warmth of classic panel design with the benefits of contemporary material science (no warping, no refinishing, no pest vulnerability), this door delivers across every performance dimension while carrying full CE certification and ISO 9001:2015 quality assurance.

• Classic Split-Panel Design in Modern Materials: Two recessed panel fields created through precision HPL thermoforming—achieves the depth and shadow-line of traditional stile-and-rail construction without the seasonal movement, joint separation, or finish cracking common to solid wood panel doors. Panel proportions can be customized (50/50, 60/40, 70/30 split) to match architectural intent.
• Anti-Fingerprint Matte Grey Surface: Proprietary hydrophobic coating reduces fingerprint visibility by 85%+ on the smooth panel fields. The consistent grey tone (available in Warm Grey, Cool Grey, Anthracite, and Greige) provides a neutral backdrop that harmonizes with virtually any interior color scheme—from warm Mediterranean palettes to cool Scandinavian interiors.
• Soundproof Composite Core: Multi-layer composite construction with high-density inner substrate (≥730 kg/m³) and timber internal framing achieves STC 33–36 dB. Acoustic performance verified per ISO 10140-2. Includes factory-installed perimeter seal channel for optional acoustic seal upgrade that boosts performance to STC 38–40.
• Wood Inner Frame Construction: Internal structural frame uses kiln-dried solid wood (moisture content 8–12% at manufacture) with mortise-and-tenon joinery, providing superior screw-holding for heavy hardware and long-term dimensional stability. All wood components receive anti-termite/anti-borer preservative treatment to GB/T 18260-2015.
• Comprehensive OEM/ODM Service: Customize panel proportions, surface color/texture, core acoustic rating, door dimensions (max 2400×1100mm), frame style (traditional rebated, concealed, or semi-concealed), hardware preparation (any lock type, hinge pattern), and packaging. Full private-label program with custom branding on protective film and packaging. Minimum order: 50 units per specification.

Ideally suited for boutique hotels, premium apartment buildings, private residential villas, high-end senior living communities, private clinic consultation rooms, and corporate executive offices where classic design language and modern acoustic performance are equally valued. The split-panel geometry provides visual interest on long hotel corridors—breaking the monotony of flat-slab doors while maintaining the cleanability and durability of laminate surfaces. The grey color family is consistently ranked among the top three most-specified interior door colors globally, ensuring broad market acceptance. Swing-type operation suits both left-hand and right-hand opening configurations with a field-reversible frame design. Reliable operation across -20°C to 45°C, with wood frame treatment ensuring pest resistance in all climate zones. Full certification package: CE EN 14351-1, RoHS, ISO 9001:2015.

Q: What grey color options are available, and can we match a specific interior design palette?

A: Our standard grey palette includes four carefully curated tones: Warm Grey (LRV 38, beige undertones for warm interiors), Cool Grey (LRV 42, blue undertones for contemporary spaces), Anthracite (LRV 12, deep charcoal for dramatic contrast), and Greige (LRV 48, grey-beige neutral for transitional designs). For OEM orders of 100+ units, we offer custom color matching—submit a physical sample, RAL code, NCS code, or spectrophotometer reading, and our lab develops a matching HPL formulation within 10 working days. We can also match specific designer paint brand colors (Farrow & Ball, Benjamin Moore, Sherwin-Williams) to within ΔE ≤1.5. Color consistency between production batches is maintained to ΔE ≤0.8 using spectrophotometric quality control at the lamination press. All colors comply with RoHS and REACH for heavy metal and hazardous substance content.

Q: How is the soundproof performance affected if I choose not to install the optional acoustic seals?

A: The door's core achieves STC 33–36 without acoustic seals—sufficient for most residential and hotel applications where the door separates rooms with different occupancy purposes (bedroom from living room, guest room from corridor). The optional acoustic seal upgrade, which includes perimeter compression seals, an automatic drop seal at the bottom, and a heavier-duty threshold, adds approximately 3–5 dB of attenuation, bringing the assembly to STC 38–40. This upgrade is recommended for situations requiring speech privacy (executive offices, consultation rooms, HR interview rooms) or where the adjacent space has elevated sound levels (mechanical rooms, elevator lobbies, entertainment areas). The seal channel is factory-routed—you can install the standard door now and retrofit seals later without door replacement. Acoustic seals add approximately 8–12% to the unit cost and are available for OEM orders of any quantity. Test certificates per ISO 10140-2 provided with acoustic-rated orders.
