How to Choose Internal Doors

Choosing the right internal doors can change the look, privacy and flow of a home. Start with the room, the opening size and the finish you want, then compare construction, glazing and any performance requirements. Browse our internal doors while using this guide to narrow down the best option for your project.

Door Style and Finish

Oak, white, walnut and painted finishes can suit very different interiors. Panelled doors offer a classic appearance, while clean contemporary designs work well in modern renovations. Glazed internal doors are useful where you want borrowed light between rooms without completely opening the space.

Door Size and Opening

Measure the existing opening carefully before ordering. Check the door width, height and thickness as well as the frame or lining. Older properties can have non-standard openings, so do not assume every doorway uses the same size.

Fire Doors

Where a fire-rated door is required, choose a product with the appropriate stated rating and follow the manufacturer's installation requirements. Fire doors work as part of a complete doorset, so compatible hinges, seals, closers and other hardware may also be required.

Door Hardware and Linings

Allow for the hardware needed to complete the installation. JJ Building Materials stocks door handles, door hinges and door linings alongside the main door range.

Before You Buy

Confirm the exact dimensions, handing where relevant, finish, glazing, fire rating and required accessories on the individual product page. This helps avoid ordering a door that looks right but is unsuitable for the opening or application.
