16 Types of Doors: A UK Buying Guide

Doors are grouped in two ways: by how they open and by what they are made from. UK homes commonly use flush, panel, French, sliding, patio, fire, bi-fold, glazed, pocket, room divider and stable doors, made from uPVC, composite, aluminium, timber or fibreglass.

Doors play a key role in every home, providing security, privacy and style. With so many choices available, picking the right one can be tricky. This guide runs through all sixteen, covering the eleven most common opening styles and the five materials they are made from, with the pros and cons of each, so you can choose the best types of doors for home use. The table below compares them all at a glance:

 

1. Flush Doors

A flush door has a flat, smooth surface on both sides with no raised panels or mouldings. It is made from a wooden frame covered with plywood or MDF (Medium-density Fibreboard). It comes in two variants: hollow core for light use and solid core for better soundproofing and strength. These doors open on hinges like standard internal doors and are great for bedrooms, bathrooms and offices, offering a clean, modern look.

Pros of Flush Doors

• Sleek and simple design for modern homes
• Affordable and budget-friendly option
• Easy to clean with stain and scratch resistance

Cons of Flush Doors

• Limited customisation after installation
• Hollow versions offer poor sound insulation
• Difficult to repair once damaged

2. Panel Doors

Panel doors have rectangular or square sections called panels set within a sturdy frame. These panels can be flat, raised, or made of glass, giving the door a decorative and classic look. The frame has vertical stiles and horizontal rails that hold the panels in place, usually two to six in total. They swing open on hinges like regular doors and are commonly used as front doors, bedroom doors, and in traditional-style homes for a timeless appearance.

Pros of Panel Doors

• Available in different styles and designs
• Timeless look fits traditional and modern homes
• Gives good insulation and sound protection

Cons of Panel Doors

• Grooves collect dust, requiring regular cleaning
• More expensive than simple doors

3. French Doors

French doors come in pairs and meet in the middle, opening either outwards or inwards. They usually have large glass panels that let in plenty of sunlight and offer a clear view of your garden or patio. Homeowners often use French doors to connect the living room or kitchen to outdoor spaces, making the home feel brighter, bigger, and more open. Their elegant design enhances both traditional and contemporary properties.

Pros of French Doors

• Brings in natural light and garden views
• Adds elegance to traditional and modern homes
• Opens wide to connect indoor and outdoor spaces

Cons of French Doors

• Needs clearance space to swing open
• Large glass areas need regular cleaning

4. Sliding Doors

Sliding doors move along a track instead of swinging open on hinges. Most sliding doors have large glass panels that let in plenty of sunlight and give a clear view of the outdoors. They save space since they do not need room to swing open like regular doors. Many homeowners use sliding doors to connect the living room to the garden or patio.

Pros of Sliding Doors

• Saves space as no swing is needed
• Lets in natural light to keep rooms bright
• Offers easy access between indoor and outdoor spaces

Cons of Sliding Doors

• Track requires regular cleaning to work smoothly
• Limited ventilation compared to fully opening doors
• It can be heavier to slide than expected

5. Patio Doors

Patio doors are large glass doors that connect your home to your garden or outdoor space. They come in different styles, such as sliding, folding or swinging. The wide glass panels let in lots of sunlight and offer lovely outdoor views, making your home feel brighter, bigger and more connected to nature. If you are torn between the two styles, see our guide to the difference between French doors and patio doors.

Pros of Patio Doors

• Lets in plenty of natural light and views
• Connects indoor spaces to outdoor areas seamlessly
• Gives your home a clean, modern look

Cons of Patio Doors

• Costs more to install than a standard door
• Large glass needs regular cleaning and maintenance
• Some styles need extra floor space clearance

6. Fire Doors

Fire doors are strong doors made from special materials that stop fire and smoke from spreading between rooms. They have thick cores that resist heat and flames, and they close by themselves when a fire starts to keep it contained. Domestic fire doors are rated FD30 or FD60, meaning they resist fire for at least 30 or 60 minutes when tested to BS 476 Part 22 or BS EN 1634-1.

You will not need one on every opening. Under Approved Document B, they are required in specific situations, such as a loft conversion that creates a third storey, or a door between an integral garage and the house.

Pros of Fire Doors

• Stops fire from spreading to other building areas
• Gives people extra time to evacuate safely
• Improves overall home safety and protection

Cons of Fire Doors

• Heavier and thicker than normal doors
• More expensive to buy and install
• Needs regular checks for safety

7. Bi-fold Doors

Bi-fold doors are made of several panels that fold like an accordion when opened. They slide smoothly on a track and stack neatly to one side, creating a wide, open space between your home and the garden or patio. The large glass panels of bi-fold doors let in plenty of sunlight, give clear outdoor views, and make your home feel warm and open.

Pros of Bi-fold Doors

• Opens up space with a wide view
• Lets in plenty of natural sunlight
• Saves space with neatly folding panels

Cons of Bi-fold Doors

• Tracks need regular cleaning to slide smoothly
• More expensive than traditional hinged entry doors

8. Glazed Doors

Glazed doors have glass panels set into a wooden, metal or uPVC door frame. The glass can be clear, frosted, or patterned, depending on how much privacy or light you want.  Internal glazed doors let natural sunlight pass between rooms, making your home feel brighter and more spacious. They are commonly used in living rooms, offices, and as entrance doors.

Pros of Glazed Doors

• Brightens rooms by sharing natural light
• Makes small spaces feel more open
• Frosted glass keeps privacy where needed

Cons of Glazed Doors

• Offers less privacy than solid doors
• Glass needs frequent cleaning

9. Pocket Doors

Pocket doors slide into a hidden space inside the wall when opened, disappearing completely from sight. They move on a smooth track system built into the wall, saving valuable floor space. Because they need special wall framing, pocket doors are best for new builds or renovations. They are ideal for small bathrooms, wardrobes, and tight spaces.

Pros of Pocket Doors

• Saves the most floor space of any door type
• Disappears from view when fully open
• Ideal for small bathrooms and tight hallways

Cons of Pocket Doors

• Needs a wall cavity, so installation is complex
• Harder to repair once fitted inside the wall

10. Room Divider Doors

Room divider doors separate large rooms into smaller spaces without adding walls. They often have multiple panels that slide, fold or swing open to create flexible living areas. Many room divider doors include glass panels that let light pass through while still dividing the space. These interior doors are great for separating living rooms, dining areas, or home offices in open-plan homes.

Pros of Room Divider Doors

• Creates flexible and private living spaces
• Lets natural light pass between rooms
• Easy to move or fold when needed

Cons of Room Divider Doors

• Offers less sound insulation
• May need regular track cleaning and care

11. Stable Doors

A stable door is split horizontally into two halves that open independently, so you can open the top for light and fresh air while the bottom stays closed and secure. Also known as a Dutch door, it began as a farmhouse design and now brings character to cottages, period homes and modern kitchens alike. Stable doors come in solid oak and dense hardwood, glazed or solid, with straight or curved head styles.

Weather seals and a solid rebate between the two halves keep draughts out when the door is closed. They suit kitchens, utility rooms and back entrances, and make an unusual front door for anyone who wants something different.

Pros of Stable Doors

• Opens the top half for ventilation and light
• Keeps pets and young children safely inside
• Adds country character to period and modern homes

Cons of Stable Doors

• Two leaves mean more seals and hardware to maintain
• Less secure than a single leaf unless bolted together
• Costs more than a standard external door

12. uPVC Doors

uPVC doors are made from strong, weather-resistant plastic that will not rust, warp or fade. They are energy-efficient, reduce outside noise, and are easy to clean and maintain. However, they have fewer design styles and can be less sturdy than timber or metal. They are commonly used for front and back doors in modern homes. For a closer look at how they stack up, read our composite vs uPVC door comparison.

Pros of uPVC Doors

• The most affordable of the five door materials
• Weather-resistant and will not rust, warp or fade
• Low maintenance, needing only an occasional wipe down

Cons of uPVC Doors

• Fewer design styles than timber or composite
• Less sturdy than timber or metal
• Colour can discolour or fade over the years

13. Composite Doors

Composite doors are made from a mix of materials, including wood, uPVC and glass-reinforced plastic (GRP). This makes them strong, weather-resistant and long-lasting. They do not fade, crack or warp easily and need little maintenance. They cost more than uPVC doors, but offer better insulation, security and a premium finish, making them ideal for front entrances.

Pros of Composite Doors

• Strong and secure, with excellent insulation
• Resists fading, cracking and warping
• Very low maintenance and long-lasting

Cons of Composite Doors

• Costs more than a uPVC door
• Cheaper models can suffer colour fade
• Cannot easily be repainted or refinished

14. Aluminium Doors

Aluminium doors are made from lightweight yet strong metal that resists rust, warping and fading. They have slim frames that allow for larger glass panels, creating a modern, stylish look. These doors are low-maintenance and very durable, making them perfect for patio or sliding doors. However, they can be more expensive, and they need a thermal break to insulate as well as other materials.

Pros of Aluminium Doors

• Strong yet lightweight, allowing slim frames and large glazing
• Resists rust, warping and fading
• Very durable and low maintenance

Cons of Aluminium Doors

• More expensive than uPVC
• Needs a thermal break to insulate properly
• Limited styling for traditional or period homes

15. Timber Doors

Timber doors are made from natural wood, offering a warm and classic look that suits both traditional and modern homes. They are strong, durable, and provide good insulation against noise and cold. However, they need regular care, like painting or varnishing, to prevent warping or rotting. Timber doors are ideal for front and internal use.

Pros of Timber Doors

• Natural warmth and character that suits any period property
• Good natural insulation against noise and cold
• Can be sanded and repainted to any colour

Cons of Timber Doors

• Needs treating or repainting every few years
• Can warp or rot if the finish is left to fail
• Costs more than uPVC

16. Fibreglass Doors

Fibreglass doors are made from reinforced plastic that looks like real wood but needs less maintenance. They are strong, weather-resistant, and do not warp, crack, or rust over time. These doors offer great insulation and can handle all weather conditions. However, they can cost more than uPVC and may dent under heavy impact.

Pros of Fibreglass Doors

• Looks like real wood with far less upkeep
• Excellent insulation and weather resistance
• Will not warp, crack or rust over time

Cons of Fibreglass Doors

• Costs more than a uPVC door
• Can dent under heavy impact
• Fewer styles and suppliers in the UK

How to Choose the Right Door for Your Home

The right door comes down to five things: where it sits, the style of your property, how secure it needs to be, how well it insulates, and how much maintenance you are willing to do. Settle those five and the choice narrows quickly.

• Where the door sits: Internal doors prioritise light, sound and space. External doors must handle security, weather and heat loss.

• Property style: Composite or timber suits detached and period homes, uPVC works well on terraced homes on a budget, and aluminium fits new builds and large glazed openings.

• Security: Look for multipoint locking, a solid core and a sturdy frame on any external door.

• Insulation: Check the U-value. Replacement external doors in England must meet Part L thermal standards, so look for a Part L compliant door if you are replacing a front or back door.

• Maintenance: Composite, uPVC, aluminium and fibreglass need very little upkeep. Timber needs treating or repainting every few years.

If you are replacing an external door, our Part L doors collection is a sensible place to start. For everything inside the house, browse the full range of internal doors.

Frequently Asked Questions

Here are answers to the questions UK homeowners most often ask when comparing door types and materials.

What is the most common type of door in the UK?

Panel doors are the most common door type in UK homes. They work internally and externally, suit period and modern properties, and come in two to six panel designs, often with glazed panels for extra light.

What type of door is cheapest?

uPVC is usually the cheapest external door material, and hollow core flush doors are the most affordable internal option. Timber and composite cost more but last longer and offer better security and insulation.

Which type of door is best for soundproofing?

A solid core panel or flush door gives the best soundproofing in most homes. Heavier timber doors and fire doors also cut noise well. Hollow core and fully glazed doors let the most sound through.

Which type of door is best for a small room?

Pocket doors and sliding doors suit small rooms because neither needs clearance to swing open. A pocket door disappears into the wall cavity, while a sliding door runs across the face of the wall.

Do internal doors need to be fire rated?

Most do not. Fire doors are required only in specific situations under Approved Document B, such as a loft conversion that creates a third storey, or a door between an integral garage and the house.

Which door material lasts the longest?

Composite and aluminium doors typically last the longest with the least upkeep. Timber can match them, but only with regular treating. uPVC has the shortest life of the five and can discolour over time.
