What Are Front Doors with Side Panels?

Written by SM Windows & Doors | Jun 3, 2026 2:08:00 PM

If you have a wide entrance or a hallway that feels a bit dark, front doors with side panels are worth understanding. They are a simple idea that can transform an entrance, bringing in daylight and filling out a broad opening that a single door would leave looking mean. Here is what side panels are, when they help, and what to think about before you fit them.

We fit doors across York and North Yorkshire, so this covers the practical points as well as the pretty ones.

What a side panel actually is

A side panel, often called a sidelight, is a fixed section that sits alongside your front door within the same frame. It is usually glazed, though it can be part-solid, and it does not open. Think of it as a slim window built into the door surround. You can have a side panel on one side or on both, and some entrances add a glazed panel above the door too, known as a fanlight or transom.

So a front door with side panels is really a door and one or more fixed glazed sections joined together as a single, wider unit.

When side panels make sense

Side panels are not just decoration. They solve real problems.

  • A wide opening: if your entrance is broad, a standard-width door leaves awkward infill on either side. Side panels fill the space properly and look intentional.
  • A dark hallway: many hallways have no other window, so they rely entirely on the front door for daylight. Glazed side panels can make a gloomy hall feel bright and welcoming.
  • A grander entrance: on larger homes, side panels give the frontage more presence and balance, especially with a symmetrical panel on each side.
  • Keeping proportions right: on period properties, side panels and fanlights often echo the original design of the entrance.

If your opening is a standard width and your hall already gets light, you may not need them. Honesty first: they are a genuine upgrade in the right home, not a must-have everywhere.

Glass options for privacy and light

Because side panels usually sit right by the street or a path, glass choice matters. You can balance light and privacy with:

  • Obscure or frosted glass: lets light through while blocking the view in. The most popular choice for privacy.
  • Decorative or leaded glass: adds character and suits period and cottage frontages.
  • Clear glass: maximum light, best where the entrance is set back or not overlooked.

You can also choose toughened or laminated safety glass for security and peace of mind, which is often required in glazing near a door anyway.

Materials and style

Front doors with side panels come in the same materials as any front door, and the panels are made to match. A composite door with matching glazed side panels is a popular, hard-wearing choice that holds its colour well in Yorkshire weather. A uPVC door with side panels is a strong value option. Whatever you choose, the door and panels are made as one coordinated unit so the colour, glass and hardware all tie together.

Style-wise, keep the side panels sympathetic to the door and the house. A clean, modern glazed door suits full-height clear or obscure panels, while a traditional four-panel door pairs beautifully with leaded or decorative sidelights.

Things to check before you commit

  • Security: more glass means the glazing spec matters. Look for laminated or toughened glass and a good multi-point lock on the door itself.
  • Heat loss: a large glazed unit needs good energy-efficient glass to avoid a cold, draughty entrance. Ask about the energy rating.
  • The structural opening: fitting side panels sometimes means adjusting the opening. A proper survey will confirm what is possible.

If any structural change is involved, or if your home is listed or in a conservation area, check the current rules with your local authority first, as requirements vary and change over time.

Rough costs

A door with side panels costs more than a standalone door because it is larger and uses more glass and framing. As a rough 2026 guide, a quality composite front door with side panels fitted often falls somewhere between about 2,000 and 4,000 pounds, depending on width, glass and finish, with uPVC often a little lower. These are ballpark figures only, so get a proper quote for your exact opening.

FAQs

What is the point of side panels on a front door?

They fill out a wide entrance and bring extra daylight into the hallway. On larger homes they also add balance and presence to the frontage. They are most useful on broad openings and dark halls.

Are front doors with side panels less secure?

Not if they are specified properly. Choose laminated or toughened safety glass for the panels and a door with a good multi-point lock, and a glazed unit can be just as secure as a solid door.

Can I add side panels to my existing door opening?

Sometimes, but it may mean widening or adjusting the structural opening, which needs a survey. If the opening is already wide, it is more straightforward. Any structural work should follow current Building Regulations.

Do side panels have to be glazed?

No. They are usually glazed to bring in light, but you can have part-solid or fully solid panels if privacy or security is the priority. Obscure glass is a popular middle ground.
