Window upgrades
Upgrading a roof window is a quick way to improve its performance without replacing the entire product. The process involves replacing the glazing unit or the sash, which increases thermal insulation, reduces energy loss and enhances acoustic comfort. All work is carried out without interfering with the roof structure, meaning no renovation or frame removal is required. This solution is dedicated to owners of older-generation windows who want to adapt them to modern energy-efficiency standards.
What does a window upgrade include?
Upgrading your windows allows you to keep what works well while adding what you need today — more warmth, comfort and everyday convenience.
Upgrading the glazing unit involves replacing the old glass unit with a modern, energy-efficient double-chamber system. This significantly improves the window’s thermal and acoustic insulation, resulting in lower heating costs and greater everyday comfort.
Window upgrades also include the option to equip your windows with new accessories — such as roller shutters, awning blinds or weather sensors. These solutions enhance functionality and allow you to tailor the interior to your individual needs, delivering a new level of comfort and aesthetics.
Signs that your roof window may need an upgrade
A roof window can operate correctly for many years, but over time it’s worth checking whether it still meets today’s standards. The most common signs that an upgrade is needed include: condensation forming on the glass, a feeling of cold near the window, draughts despite the window being closed and difficulty maintaining thermal comfort. Older models, even with solid construction, can cause higher energy losses and lower heating efficiency. In homes with mechanical ventilation or heat recovery, it is also important to ensure the window is compatible with the ventilation system. The solution may be replacing the glazing unit or the sash with a modern triple-glazed unit offering improved insulation and durability — without the need to replace the entire window.
Solid foundation, new possibilities
At FAKRO, we design roof windows for long-lasting, trouble-free use. Their robust construction, when maintained regularly, preserves its performance even after several decades — we still encounter models from years ago in excellent condition. Modernisation is a simple way to enhance window performance, especially thermal insulation. With an authorised service team, you can be sure that your warranty remains valid, and new components come with an additional 2-year protection. Instead of replacing the entire window, all you need is a new glazing unit or sash. It’s a quick, non-invasive and economical solution that requires no intervention in the roof covering.
Benefits of roof window upgrades
Upgrading is a quick way to improve comfort in your home without replacing the entire window. Replacing the glazing unit or the sash takes around an hour and does not require removing the frame or interfering with the roof structure. The work is non-invasive and can be carried out all year round. It’s a convenient solution that enhances the window’s performance without unnecessary renovation. You gain better thermal insulation, lower heating costs and reduced condensation on the glass. The window performs like new — saving you time, money and improving everyday comfort.
Automation of manual products
Do you have a manually operated FAKRO pivot roof window? Now you can modernise it by switching from manual to automatic control — without needing to replace the entire window. This upgrade allows you to operate the window using a remote control, mobile app or weather sensors (such as rain sensors). It’s the perfect solution for hard-to-reach or frequently used windows. Automation increases convenience, supports ventilation and aligns with the concept of a smart home. With the drive installed, you can also automate FAKRO accessories — such as roller shutters and awning blinds — creating a cohesive, modern control system.

FAQ
What upgrade options are available for roof windows, and which one is best for my needs?
Roof window upgrades can include various actions — from simple improvements to more advanced service work. The most common options include: replacing the glazing unit with an energy-efficient version, installing new perimeter seals, adjusting window mechanisms, improving the performance of air inlets and adding accessories such as roller shutters, awning blinds or insect screens.
The best solution depends on the technical condition of the window and what you want to achieve. If the frame and the frame structure are in good shape, replacing the glazing unit or the sash is enough to significantly improve thermal insulation and user comfort. When minor air leaks appear or mechanisms become less smooth, adjustments, seal replacements or improving inlet performance may be the right choice. Upgrades offer great flexibility — we tailor the solution to your needs without interfering with the roof structure or interior.
What are the benefits of upgrading a roof window instead of replacing it?
Upgrading is a faster, simpler and more cost-effective way to improve window performance compared to a full replacement. There is no need to disturb the roof or remove the frame, which reduces both labour time and costs. You gain better thermal and acoustic insulation, improved indoor comfort and you maintain the existing aesthetic and functionality. It’s the perfect solution when the window still operates correctly but needs refreshing or adapting to current energy-efficiency standards.
Can upgrading a roof window improve thermal insulation?
Yes — improving thermal insulation is one of the main goals of an upgrade. Installing modern triple-glazed units with low-emissivity coatings and noble gas fills (argon or krypton) significantly improves heat transfer. Better insulation means lower heat loss, reduced heating bills and improved comfort throughout the year. It also reduces the risk of condensation on the glass and increases the overall energy efficiency of your home.
Is upgrading a roof window more cost-effective than buying a new one?
In many cases — yes. Upgrading is significantly cheaper than purchasing and installing a new window, while still providing comparable improvements in thermal and acoustic comfort. It requires no construction work, is less time-consuming and allows you to maintain the existing appearance of the roof. It’s an excellent solution for those who want to improve the performance of their windows without the cost and inconvenience of replacing the entire structure. Additionally, the service is covered by warranty, and all work is performed by an authorised service team.
What are the expected costs and duration of a roof window upgrade?
The cost of an upgrade depends on the type of window, the scope of the service and the location. Pricing is prepared individually based on the serial number and available information. The upgrade itself typically takes around 1 hour per window.
Will upgrading a roof window require additional structural work or changes to the building façade?
No — an upgrade does not require interference with the roof structure or changes to the façade. All work is carried out from the inside and involves only the removal and installation of the glazing unit or sash. This means no dust, no disruption and no risk of damage. It is a quick and safe solution, especially for roofs with delicate coverings such as felt roofing or bitumen shingles. An upgrade preserves the building’s appearance while significantly improving the window’s performance.
