Transom windows – everything you need to know!

Written by

Reading Time: 4 minutes

Transom windows have long been a timeless architectural feature. They improve both aesthetic appeal and functionality in homes. If you’re looking to bring in more natural light, boost ventilation, or add a decorative touch, transom windows are your choice.

But what exactly are transom windows, and why are they gaining popularity in modern home design? In this guide, we’ll cover everything you need to know – from the benefits of transom windows and design ideas to energy efficiency. You will also know how to choose the right model for your home.

What are transom windows?

A transom window is a fixed or operable window installed above a door or another window, typically separated by a horizontal beam called a transom bar. Originally used in historic buildings to improve airflow, modern transom windows are now popular for their decorative and functional benefits.

They are available in various styles and materials – including uPVC and aluminium – and that makes them a versatile choice for both classic and contemporary homes.

The benefits of transom windows

Installing transom windows in your home comes with multiple advantages, including:

Increased natural light

Transom windows allow more daylight into a room, yet they provide privacy. This is especially useful in areas with limited wall space for standard windows – such as hallways, bathrooms, or above entry doors.

Improved ventilation

Certain operable transom windows can be opened to let in fresh air – to enhance airflow and reduce the need for mechanical ventilation. This is useful in stuffy rooms or humid environments – like bathrooms.

More elegant appeal

Transom windows add architectural character, making a home look more stylish and sophisticated. Whether used in traditional or modern settings, they create a sense of height and openness.

Higher energy efficiency with transom windows

When paired with double or triple glazing, transom windows help improve a home’s energy efficiency. They contribute to better insulation, reduced heat loss in winter and minimised heat gain in summer. Fenbro’s uPVC and aluminium transom windows are designed to provide excellent thermal performance – to keep your home comfortable all year round.

Compatibility with other windows and doors

One of the biggest advantages of transom windows is their flexibility. They can be installed above:

  • front doors for a grander look
  • patio doors to increase natural light
  • standard windows to create a larger, visually appealing window arrangement

Looking for high-quality transom windows? Fenbro offers uPVC and aluminium models that are compatible with any main window or door structure.

Transom window design ideas

When choosing a transom window design, at first think of your home’s style and functional needs. Here are some popular ideas to get you inspired:

Fixed transom windows for a clean, modern look

If your goal is aesthetic enhancement, a fixed transom window can create a nice, uninterrupted glass effect. This solution is perfect for modern homes that prioritise natural light without additional ventilation.

Decorative transom windows for a classic feel

For traditional or period-style homes, opt for ornate transom designs. Arched, divided-light, or frosted glass transom windows add that unique, elegant touch to your home’s appeal.

Operable transom windows for ventilation

If airflow is your priority, choose a hinged or louvred transom window. They work well in bathrooms, kitchens, and home offices – places where improved air circulation is beneficial.

Transom windows above French or sliding doors

Installing transom windows above French doors or sliding patio doors creates a stunning indoor-outdoor connection. They make the space feel much brighter and more open.

Customising transom windows to reflect your style

Need something exceptional? Here’s the good news – you can personalise your transom windows. Consider incorporating decorative glazing options – like stained or frosted glass – to add an artistic flair and maintain privacy. Select bespoke frame finishes and colours to make sure that the transom windows smoothly integrate with your existing décor. By tailoring these elements, you both improve the visual appeal of your space and create a distinctive feature. Personalisation is important – it helps you reflect your own taste.

How to choose the right transom windows

When selecting transom windows, consider these key factors:

1. Material: uPVC or aluminium?

  • uPVC transom windows – affordable, low-maintenance, and excellent for thermal insulation.
  • Aluminium transom windows – durable, good-looking, and ideal for modern architectural designs.

2. Fixed vs operable

Decide whether you need a fixed transom window for design purposes or an operable one for added ventilation.

3. Glazing options for energy efficiency

  • Double glazing provides good insulation and is the cost-effective option.
  • Triple glazing offers better thermal and acoustic performance – it’s an ideal option for energy-conscious homeowners.

4. Compatibility with your existing windows and doors

Make sure your transom window complements your current window and door designs. Fenbro’s transom-compatible windows allow for smooth integration with various window styles. Not sure what to choose? Fenbro’s experts will help you select the best option.

Transom window installation – what to expect?

Proper transom window installation is essential to provide durability, energy efficiency, and long-term performance. The process typically includes:

  • Measuring and preparing the opening – ensuring the correct fit and structural integrity.
  • Installing the frame – positioning and securing the transom window in place.
  • Glazing and sealing – fitting the glass and applying seals for insulation and weatherproofing.

For larger installations, professional fitting is highly recommended. Fenbro’s team of experts guarantees precise installation for maximum performance. So, if you’re looking to brighten up your space, improve ventilation, and boost your home’s aesthetic appeal, transom windows are an excellent choice. Whether you opt for a fixed or operable design, uPVC or aluminium, double or triple glazing – Fenbro has a solution tailored to your needs.
