Product Information
Contemporary interiors call for simplicity and style, and the white smooth ladder 4 panel internal door delivers both. With its clean ladder-style layout, often referred to as the Linear or Colorado design, this model provides a crisp, modern appearance that complements today’s new build homes perfectly. The subtle horizontal lines create visual interest without overpowering the space, giving each room a bright, refined finish.
Designed with practicality in mind, these doors are supplied white primed and ready for on-site painting, allowing flexibility to suit any décor or design palette. The smooth MDF surface ensures an even, professional result once finished, while the lightweight hollow-core construction makes handling, installation, and transport simpler for builders and developers working on larger housing projects. For higher-spec applications or where safety compliance is essential, an FD30 fire-rated option is available, featuring a robust solid core that meets stringent performance standards.
Manufactured using a framed moulded construction, this model includes primed edges and 300x82mm lock blocks on both sides, positioned precisely in line with the door centre. The attention to detail in this structure ensures straightforward fitting and a dependable long-term solution for trade professionals. The standard non-fire-rated doors can be trimmed by up to 6mm from any edge, while the FD30 fire-rated variants are equipped with 18mm lippings that allow trimming of up to 12mm for perfect alignment in any frame.
These doors are supplied in both imperial and metric sizes, with bespoke options available on extended lead times for developments requiring non-standard dimensions. Offering an economical solution that balances quality and value, the white smooth ladder 4 panel range is particularly suited to volume installations in new housing developments, apartment projects, and large-scale refurbishments. Each door is supported by a 10-year Manufacturing Defects Guarantee, reinforcing reliability for long-term peace of mind.
Sizing
Available in all popular imperial and metric sizes to suit standard UK frames. Non-fire-rated versions allow 6mm of trimming from any side, while FD30 fire-rated models can be adjusted by up to 12mm. Bespoke sizes are available upon request for large projects or unique openings.
Sustainability
Constructed from responsibly sourced materials, this door range is certified under the FSC® Mix (INT-COC-003944.500) scheme, supporting sustainable forestry and environmental responsibility. Choosing FSC-certified products helps reduce environmental impact and aligns with the growing sustainability goals of new housing developments.
Coordinating Your Interior Design
The white smooth ladder 4 panel collection works beautifully throughout modern homes. Whether paired with complementary glazed versions to maximise light or installed across living areas, bedrooms, and hallways for a unified look, the design maintains continuity across every space. The fresh white primed surface ensures flexibility, enabling decorators or contractors to finish in any shade that complements the interior theme. For larger developments, bulk pricing and consistent stock availability make this an ideal solution for developers seeking quality doors that meet tight project schedules.
