Side Panels and Top Lights for UPVC & Composite Doors

What are side panels and top lights?

In short, these are the glass or solid sections that surround some composite and UPVC doors.

You may know them by different names

Side panels are also referred to as side lights or side screens, while top lights are also known as top boxes or fan lights. Despite the seemingly different names, they can be used interchangeably, whether glazed or solid, rectangular or curved.

They fill up the doorway

If the inner hall is large enough, the doorway will reflect this. Either solid panelling will fill up the space, or glass will allow for more light into this larger hallway.

 

 

Will I need to replace my side panel or top light when I order a new door?

It’s understandable that one might wish to keep their existing top light or side panels, either for sentimental reasons or to save costs. However, there are instances where each will need to be replaced.


Most side panels need to be replaced

As side panels tend to be a part of the door frame, it will be necessary to replace these with your old front or back door. While it is possible to keep a larger side panel that is separate from the door frame, this is not advised as the style and quality will not match.


Some larger top lights can be kept

Some taller top lights are separate from the door frame, in which case replacement is not necessary. For the same reason as replacing the side panel, a new top light will create uniformity with a new door.


Flag windows can also be kept

Flag windows are generally separate from the door frame, even having a separate cill. Therefore, keeping a flag window is possible. As with a top light or side panel, it is recommended to replace your flag window to better match the aesthetic of your new composite or UPVC door.

 

What are the advantages of replacing my side panel or top light along with my door?

A replacement is a good idea in order to match the style and look of your new front or back door, and we use the same high-quality glass and frame profile as we do with our doors.


A new top light or side panel can be matched to your door

With several finishes available, you can match a new top light or side panel with that of your new door, allowing for a seamless appearance.

Better all-round security and insulation

Just like our composite & UPVC doors, the glass we use is toughened to withstand blunt force, and uses warm edge spacer bar technology to reduce heat loss. The UPVC structure of the side panels and top lights is steel-reinforced, and where couplers are needed, we use strong aluminium.

What are my options for a side panel or top light?

This is largely dependant on the size and shape of your doorway, but we offer several options for privacy and appearance.

Glazed or solid

Glass allows for natural sunlight to enter the home, while solid panelling can prevent snooping from strangers passing by. Panelling can be fully flat or grooved, and offers maximum obscurity, albeit at the expense of sunlight. Alternatively, we offer backing glass patterns of various privacy levels that not only obscure viewing into your home, but which also allow natural light to enter. Bespoke glass designs are also a possibility.

 

Rectangular or arched

The majority of homes will have rectangular side panels and top light, while some, particularly period homes, will have an arched top light, or even part arch in shape. Side panels can also be arched in conjunction with a top light to accommodate a large curved doorway.

 

Single or double side panels

Generally, we try to match the configuration of your existing doorway. However, if the doorway allows for it, twin side panels or a larger single panel are viable options.

Full height or midrail

The side panel can have full height glass or solid panelling, or with a midrail have the additional option to be half glazed (glass in the top, solid in the bottom). For wider side panels, a midrail provides extra strength.


Top Hopper

For side panels of sufficient width, an opening window known as a top hopper can be added. It offers the advantage of letting out hot air and letting in cool air during summer months.


Numerals and cat flaps

Side panels that are wide enough can accommodate a cat flap or pet door for dogs, either within solid panelling or glass. A top light has the option for numerals, either sandblasted or etched into sandblast. Both options free up your choice of new door, as some door styles cannot accommodate numerals or cat flaps.

What should I expect to pay for top lights or side panels?

Size and colour are the main factors affecting price, with glass or solid panelling generally not adding to the cost.

Colour matching will cost more

Matching the colour of the side panels and top light to that of the door will increase the cost, with our prestige finishes costing more than standard and superior colours. A bespoke painted colour will further add to the price.

No difference in price between glass or solid, midrail or not

Whether there is clear or backing glass, solid panelling, or a midrail, the price is the same. However, in the case of glass with numerals, the cost will increase.

Size matters, and so does shape

The width of side panels can make a difference to the overall cost. Being arched will also add to the cost of a top light, as well as side panels should they need to be curved as well.
