Why Buy Internal Doors from Emerald Doors?
A Style for Every Room
From classic oak and walnut to painted white, grey and bold colours, our internal doors cover traditional, contemporary and designer looks to suit any interior.
Solid and Engineered Builds
Most of our internal doors use an engineered core for strength and stability, so they resist warping and twisting better than cheaper solid timber alternatives.
Glazed and Solid Options
Choose glazed internal doors to borrow light between rooms, or solid unglazed doors for privacy and a clean panelled finish.
Fire Doors Available
Many designs come as FD30 fire-rated versions, certified to BWF Certifire or BS 476 Part 22, for rooms where building regulations require them.
Made to Measure Service
If a standard size will not fit, we make internal doors to measure, so you can match awkward or period openings without compromise.
10 Year Guarantee
Every internal door is backed by our conditional 10-year guarantee against faulty materials or workmanship, with a price promise and a 4.7 out of 5 eKomi rating.
FAQ About Internal Doors
What are internal doors?
Internal doors, also called interior or inside doors, are the doors used between rooms inside your home. Unlike external doors, they are not built to withstand the weather, so they focus on style, sound reduction and everyday durability.
What size are standard internal doors in the UK?
The most common UK internal door sizes are 1981mm x 762mm and 1981mm x 838mm, which is 78 inches by 30 or 33 inches. We also stock metric and made-to-measure sizes, and most doors can be trimmed slightly for a precise fit.
What are internal doors made from?
Our internal doors use engineered cores finished in real oak and walnut veneers, or primed and painted faces in white, grey and colours. Engineered cores stay straighter than solid timber, which matters across a centrally heated home.
What is the difference between solid and hollow internal doors?
Hollow core doors are light and budget-friendly but offer little sound insulation. Solid and engineered core doors, which we focus on, feel more substantial, reduce noise between rooms and stand up better to daily use.
Should I choose glazed or solid internal doors?
Glazed internal doors let light flow between rooms and suit hallways and darker spaces, while solid doors give more privacy and noise reduction for bedrooms, bathrooms and studies. Many ranges offer both.
Do you supply internal fire doors?
Yes. Many of our internal doors are available as FD30 fire-rated versions, certified to BWF Certifire or BS 476 Part 22. These are required between an integral garage and the house, and in many flats and homes over certain heights.
Do internal doors come finished or unfinished?
We offer both. Pre-finished doors arrive ready to hang with the finish already applied, while unfinished doors let you paint or stain them yourself. See our prefinished and custom finished collections to choose.
How do I measure for a replacement internal door?
Measure the height, width and thickness of your existing door, not the frame, and use the largest reading if sizes vary slightly. If you are between sizes, order the next size up and trim to fit, or use our made-to-measure service.
