Door Lining & Casings

Learn more about door linings and casings

Door linings and casings act as the bridge between your structural wall and your internal door. Beyond aesthetics, they provide the necessary support to prevent door sagging and ensure smooth operation. At Travis Perkins, our products are sourced from sustainable forests, ensuring that your project is both high-quality and environmentally responsible.

 

A high-quality internal door is only as good as the frame that supports it. Our range of door linings and door casings provides the essential structural foundation needed for a flush, professional finish in any renovation or new build. Whether you require moisture-resistant MDF for a bathroom or premium solid oak for a high-end interior, our timber is precision-machined to prevent warping and ensure long-term durability.

 

From standard internal door frames to specialized fire-rated door linings, we stock sizes to suit all common UK wall thicknesses. Ensure your project meets building regulations without compromising on aesthetics. Explore our collection today to find the perfect match for your joinery needs and benefit from trade-quality materials built to last.

 

Typical uses

 

• New Build Construction: Creating standard openings for internal rooms.

• Renovations: Replacing old, warped frames during a home layout change.

• Fire Safety Upgrades: Installing certified frames to support fire-resistant doors in HMOs or commercial properties.

 

How to choose the right door linings and casings

First, identify if you prefer a lining (used with separate door stops) or a casing (integrated rebate). Next, consider the material: MDF is cost-effective and resistant to warping, whereas solid timber offers superior strength and a natural grain. Finally, ensure the width matches your finished wall thickness to avoid gaps when fitting architraves.

 

Before you order

 

• Double-check your structural opening measurements and the thickness of your finished wall. 

• If you are fitting a fire door, remember that you must use a specific fire-rated lining to meet UK Building Regulations. 

• Also, consider if you need additional architrave to finish the look.
