Transform your loft with VELUX: light, air and endless possibilities
Converting a loft space is an exciting way to maximise existing space. Whether you’re turning it into a bedroom, home office, or even a cosy lounge, there is one element that can make all the difference – the addition of VELUX roof windows. They bring light, fresh air and a sense of space to often dark and cramped areas.
VELUX roof windows can offer numerous benefits in your loft conversion, read on to discover how they can transform your space.
Increasing natural daylight
One of the most significant advantages of roof windows is the amount of natural light they provide. More often than not, roof windows can be the only source of daylight in a loft space – did you know that you get 2.5 times more daylight from roof windows than façade windows of the same size? Opting to add roof windows into your loft conversion will flood the space with daylight, making it feel larger, brighter and more inviting.
The number, type and size of roof windows in a room will have a substantial effect on the amount of daylight and fresh air in that space. It’s recommended that your glazing is at least 20% of the floor space – placing multiple VELUX roof windows side by side in a combination of sizes and styles will help you maximise daylight and achieve this.
Headroom, in loft conversions, is naturally reduced – the outward opening VEUX top-hung roof window will help create a balcony like feeling and maximise space. Available in electric or manual operation.
You may opt for the VELUX Balcony roof window that transforms from a roof window into a balcony in seconds. This innovative roof balcony window gives you the feeling of more space and fills your room with daylight and fresh air. It’s a balcony experience like no other.
The VELUX Dormer transforms spaces with a dramatic increase in natural daylight and an amazing feeling of openness. This innovative alternative to traditional dormers increases usable space and headroom while creating a bright and airy atmosphere. A VELUX mini Dormer solution is an easy way to increase the useable area in your loft, creating a big impact with a boost of natural light and space. Combine with solar, electric or manual roof windows or try a mix.
Ventilation and fresh air
Another great feature of roof windows is the ability to open them for ventilation. Loft spaces can become stuffy and warm, especially in summer. With roof windows, you can easily let fresh air circulate, ensuring a more comfortable environment throughout the year.
Imagine a perfectly aired out home before you even step through the door. Or your roof windows closing automatically when it starts to rain thanks to a clever built-in rain sensor. VELUX solar roof windows offer the full package and can be operated via the VELUX App control – at home or on the go.
The finishing touches
You may be torn between a variety of interior finishes but one finish that stands out from the rest for its unique benefits is the VELUX white maintenance-free interior finish. It is durable, easily cleaned, moisture resistant and as the names suggests – completely maintenance-free.
Loft conversions are predominantly transformed into bedrooms so ensure you get a restful night’s sleep by adding VELUX blackout blinds. Available in solar, electric and manual operation in a wide range of colours to suit your décor.
Consider installing VELUX external Anti-heat products to prevent direct sunlight from entering the home and reduce rain noise – also available in solar, electric and manual operation.
For the ultimate convenience and control of your VELUX solar and electric roof windows, blinds and shutters choose from a range of smart control solutions available including VELUX ACTIVE and VELUX App Control.
Conclusion
Choosing VELUX roof window can elevate the design and functionality of a loft conversion and create a healthier indoor climate for you and your family. With the right style, size and finish of roof windows, you can maximise your loft’s potential and enjoy a bright, comfortable and functional space that you’ll love for years to come.
If you’re planning a loft conversion, consider installing VELUX roof windows to take your design to the next level!
Blog post: VELUX Installer Replacement Guide
There’s a quiet opportunity sitting above the heads of millions of homeowners.
A generation of VELUX roof windows, installed during the housing boom of the 1980s and 90s, is reaching the end of its natural life. Seals are failing. Frames are weathering. Energy performance has fallen decades behind modern standards. And homeowners? They’re ready to upgrade – they just need you to show them how straightforward it is.
The replacement opportunity has never been bigger. Here’s everything you need to know to make the most of it.
For Installers: Fast, clean, profitable jobs
This is where it gets compelling for your business. Because VELUX has maintained consistent roof window sizing for decades, most replacements are a straight, same-day swap – no reworking the roof, no major internal alterations.
In most cases, a replacement job can be completed in under 4 hours, entirely from inside the home.
That means:
- Minimal disruption for the homeowner
- No need for scaffolding in most cases
- Clean, efficient jobs that protect your reputation
- More jobs completed per week
Identifying the roof window: Understanding VELUX generations
Before you specify, you need to identify what’s already in the roof. The data plate on the existing roof window is your starting point – it tells you the roof window type, size code, glazing type, and production code (which reveals the age and origin of the unit).
Here’s a quick guide to VELUX generations:
One important exception: There’s no modern like-for-like replacement for the GGL-5. The closest option is an FK06, which is 40mm narrower. Use the EL/EW 6000F flashing (which includes insulation foam) to bridge the gap neatly between the new window and the existing roof timbers.
Minor adjustment note: When replacing sizes GGL 102, 104, or 206, minor plasterboard adjustments will be required.
Choosing the right flashing:
Getting the flashing right is critical – and it comes down to one question: how old is the existing roof window?
Replacing a window installed before 2001?
Choose an EL or EW replacement flashing. These are specifically designed so that the new roof window sits directly onto the existing internal lining, with no internal alterations required. The new roof window slots in, the brackets supplied with the flashing do their job, and the job is done cleanly.
- EL flashing — for slate roofs up to 8mm thick
- EW flashing — for profiled roofing material up to 120mm
Both come in two versions:
- 1000 — includes underfelt collar
- 6000F — includes underfelt collar and insulation
Replacing a window installed after 2001?
Use a standard flashing. Suitable for newer roof windows, same professional result.
The Upsell conversation: Turn a replacement into an upgrade
Here’s where you can significantly increase your margin – and genuinely delight your customers.
A replacement job is the perfect moment to have an honest conversation about what’s possible. Most homeowners don’t realise they can upgrade at the same time, within the same roof opening. Here’s what to mention:
Upgrade the finish
Old timber frames can be replaced with a white maintenance-free (PU) interior – the most durable and robust finish available, and completely maintenance-free going forward. It’s an easy sell once you show homeowners what it looks like.
Upgrade the operation
For roof windows that are hard to reach, solar operation is a genuinely impressive upgrade. No electrician required, no wiring to run – the roof window is powered by the sun (and still works on cloudy days).
Upgrade the glazing
For homeowners near busy roads, under flight paths, or simply after better thermal performance, triple glazing is a compelling option. Better insulation, meaningful noise reduction, and future-proofed energy performance.
Complete the look with blinds and shutters
No transformation is complete without accessories. VELUX blinds and external shutters are manufactured specifically for each roof window, so they fit perfectly and install quickly. They also significantly increase the value of the job.
The key is making sure homeowners know what’s possible before you start the job – not after. A short conversation upfront can transform a straightforward swap into a premium installation they’ll talk about for years.

You’ll get access to exclusive training courses (including in-depth replacement training), VELUX Rewards, and the support to grow this side of your business confidently.

Why every extension deserves VELUX roof windows

Let there be light
Natural light is one of the most sought-after features in modern homes. VELUX roof windows and bi-fold doors work in combination, creating a lighter and brighter space. Roof windows transform the way light flows into a room throughout the day and allow more natural daylight to penetrate into the existing part of the home. Placing multiple VELUX roof windows side by side in a combination of sizes and styles will help you maximise daylight in your extension project.
Did you know- increased daylight exposure directly impacts our mood, our sleep,focus, hormone levels, immune system and our ability to cope with stress? Making it not only a sought-after feature in a home but a valuable addition for you and your family’s health.
Natural ventilation and fresh air
Many home extensions, such as kitchens or open-plan living areas benefit from improved ventilation. VELUX roof windows provide an easy way to introduce natural airflow, helping to eliminate cooking odours, reduce condensation, and prevent the build-up of moisture and heat. The result is a healthier, more comfortable indoor environment for you and your family.
With VELUX solar or electric roof windows, you are in control at the touch of a button and can pair your roof windows and blinds with smart controls like VELUX ACTIVE or VELUX App Control. Each roof window features an integrated rain sensor that automatically closes the roof window when it starts to rain, allowing you to ventilate your home without having to worry about the weather.
Design flexibility
VELUX offers solutions for sloped, low pitch and flat roofs – giving you full design freedom. Enhance your sloped roof extension project and install multiple VELUX solar roof windows. These innovative solutions bring more fresh air, natural daylight and everyday convenience to your home.
VELUX Low pitch roof windows are engineered to remain fully watertight even at low roof pitches (10°-20°) and feature sleek glass-to-edge technology for a modern, elegant exterior finish.
For flat roof extensions, VELUX solar operated glass rooflights offer the same benefits of daylight and ventilation, combined with a state-of-the-art design that adds style and ease of use to your living space.
The final details
When planning your extension, considering how to manage light and temperature is crucial for creating a comfortable and enjoyable space. VELUX offers a wide range of internal blinds and external Anti-heat products designed to soften or block out the light, regulate the temperature and even reduce rain noise.
Conclusion
When planning a home extension, it’s easy to focus on floor space and layout, but don’t overlook the potential of the roof. VELUX roof windows can transform a standard extension into a bright, welcoming space that feels like the true heart of your home. From improved comfort and enhanced natural light to greater design flexibility, the need to incorporate VELUX roof windows into your extension project cannot be overlooked.
The replacement opportunity is out there. Homeowners are ready. The jobs are fast, the margin is strong, and the opportunity is only getting bigger. Now’s the time to make the most of it.
