Product Information

Modern homes demand both visual consistency and safety assurance, and the white smooth ladder 4 panel fire door delivers exactly that. Featuring a clean, horizontal ladder-style layout, also known as the Linear or Colorado design, this model offers a contemporary look that aligns perfectly with today’s new build developments. The smooth, white primed surface creates a bright and adaptable finish that blends easily with a wide range of interior themes.

FSC Certification

Built with reliability in mind, every door in this range includes a solid fire-rated core designed to provide 30 minutes of certified fire protection. This performance makes it a trusted choice for developers and contractors who need to meet stringent building regulations while maintaining a unified appearance throughout a property. The white primed MDF skin gives a smooth, consistent surface ready for on-site painting, helping create a professional finish that complements modern interiors.

Supplied in the most popular imperial and metric sizes, this fire-rated version is crafted with 18mm lippings and can be trimmed by up to 12mm from any edge, allowing for accurate installation even in challenging frames. Bespoke sizing can be arranged on extended lead times, offering flexibility for larger projects or unique specifications. Non-fire-rated variants in 35mm and 40mm thicknesses are also available, making it simple to maintain a consistent look across fire-rated and non-rated areas of a development.

For builders working on volume housing projects or apartment complexes, this range combines cost-effective production with proven safety performance and straightforward handling. Supported by a 10-year Manufacturing Defects Guarantee, it’s a dependable choice that meets the needs of large-scale installations without compromising quality or compliance.

Sizing

Manufactured in all standard imperial and metric sizes, this FD30 model includes 18mm lippings for trimming up to 12mm on any edge. Non-fire-rated versions are also available in 35mm and 40mm thicknesses. Custom sizes can be produced on request to meet specific project demands.

Sustainability

Each door is made using responsibly sourced timber materials and certified under the FSC® Mix (INT-COC-003944.500) scheme. This ensures that the wood used in production comes from well-managed forests, supporting sustainable building practices for developers focused on environmental responsibility and long-term value.

Coordinating Your Interior Style

The white smooth ladder 4 panel fire door integrates seamlessly with matching non-fire-rated models to create a unified interior look across any new build property. Perfect for multi-plot developments or apartment blocks, the collection allows consistent design flow while meeting varying safety requirements throughout a building. With its adaptable white primed surface, decorators can easily customise the finish to complement any interior palette. The combination of contemporary styling, safety performance, and large-scale suitability makes this door an excellent choice for developers seeking dependable and visually appealing solutions.
