From raw material calibration to final automated finishing, discover how we build strength and durability into every door system.
Why multi-national developers and building materials importers shift to engineered PVC Laminated Wood & WPC Door systems.
Standard wood doors absorb moisture, warp in coastal humidity, and crack under high temperatures. Our engineering-grade PVC Laminated doors utilize high-density WPC (Wood Plastic Composite) and moisture-barrier PVC foils. These block water vapor and maintain dimensional stability in extreme environments.
For large multi-family real estate projects or major hotels, maintenance is a major operating expense. PVC laminated options do not need regular painting, staining, or sanding. The anti-scratch polymer exterior withstands high-traffic wear from luggage, carts, and cleaning equipment.
By matching WPC frame cores with mineral wool or high-density engineered fiberboard and fire-rated sealants, Larsom doors achieve certified fire ratings from 1 to 3 hours. Advanced structural designs also block external sound transmission to meet modern building requirements.
From standard luxury residential builds to heavy-duty institutional facilities.
Developers require aesthetic consistency, fast installation, and long-term durability. Our interior flush wood doors, combined with PVC laminate finishes, match modern interior styles while reducing installation labor. Our door frame systems fit seamlessly into varying dry-wall or wet-wall thickness parameters.
Hotels need quiet guest rooms, elegant entryways, and robust structural integrity. Larsom’s premium soundproof, fire-resistant custom wooden doors are engineered with solid mineral cores, intumescent seals, and digital key lock integrations to enhance guest safety and convenience.
Pioneering green polymers and structural engineering for next-generation architectural projects.
Moving beyond conventional PVC. Larsom’s research team works with bio-based polymers combined with recycled organic wood flour. This reduces environmental impact and provides improved UV fade protection and scratch resistance.
Using PUR (Polyurethane Reactive) hot melt laminating adhesives ensures zero VOC outgassing. Larsom doors meet strict international environmental standards, including LEEDS, European E0 emissions, and Japanese F4Star certifications.
We integrate internal pathways and conduits for smart systems. This allows for clean wiring runs, hidden magnetic contacts, and built-in power paths for fingerprint, facial recognition, and remote access systems.
Smooth ocean transport, strict inspection procedures, and reliable delivery across 130+ countries.
We test every production batch to verify performance standards:
Our location in Zhejiang provides easy access to Ningbo and Shanghai ports, helping to minimize land freight transit times and shipping costs.
Answers to common technical, structural, and logistics questions from professional buyers and structural engineers.
MDF PVC laminated doors use medium-density fiberboard sheets wrapped in a protective PVC finish, which is excellent for dry interior environments. WPC (Wood Plastic Composite) doors combine wood fibers and polymer resins. This makes them highly waterproof and resistant to rot, making them suitable for high-humidity areas like bathrooms, kitchens, and tropical climates.
Yes, our custom timber and composite doors can be manufactured with specialized fire-resistant mineral cores and heat-expanding intumescent perimeter seals. We offer constructions certified for 30, 60, 90, and up to 120-minute fire ratings under BS 476, EN 1634, and UL standards.
We use high-temperature polyurethane (PUR) hot-melt adhesive lines. Unlike water-based options, PUR forms a cross-linked chemical bond that resists humidity, heat, and moisture. This prevents edge peeling and surface bubbling, even in hot or humid environments.
Our standard Minimum Order Quantity (MOQ) is 20-30 sets per design, which optimizes shipping container space. For regular production runs, typical lead times range from 20 to 30 days from order confirmation, depending on the scale and complexity of the project.
