Step 1 – Open Your VELUX Window
Gently open your roof window so you can access the top edge of the sash (the moving part of the window).
The identification plate is not visible when the window is closed, so you will need to open it slightly to locate it.
Step 2 – Locate the Identification Plate
Once the window is open, look along the top edge of the sash. You’ll see a small metal plate or sticker fixed into the frame.
This plate contains important product details, including:
- Model code
- Size code
- Additional manufacturing information
It’s usually silver, grey, or black with printed text.
Step 3 – Note Down the Window Code
On the plate, you’ll see a combination of letters and numbers.
For example:
- GGL MK04
- GGU CK02
- GPL FK06
The size code (such as MK04, CK02 or FK06) is the most important part when selecting your blind. Make sure you copy it exactly as shown, including any letters.
Once you have this code, you can confidently choose the correct blind size in our calculator.
If you’re unsure or the label is worn or difficult to read, simply take a clear photo of the plate and contact us. We’ll be happy to help you confirm the correct window code before you place your order.

VELUX Anti-heat blind
VELUX Anti-Heat Blinds are installed externally to block the sun’s rays before they reach your roof window, helping to reduce indoor heat while maintaining daylight and your outside view. Designed and manufactured by VELUX specifically for VELUX roof windows, they offer effective heat protection with a precise factory fit.
Use the configurator below to enter your VELUX window code (e.g. MK04, GGL, GGU) and customise your ideal anti-heat blind, choosing manual, solar or electric operation. Supplied by Limehouse Roof Blinds, an official VELUX Authorised Dealer.
VELUX Anti-Heat Blind – Exterior Heat Protection with Daylight Retention
The VELUX Anti-Heat Blind is an exterior roof window blind designed to reduce solar heat before it passes through the glazing. By stopping the sun’s rays externally, it helps keep indoor temperatures more comfortable during warm, sunny days without sacrificing natural light.
Unlike interior blinds, which manage light after it has entered the room, this genuine VELUX anti-heat blind works at the source, making it a highly effective solution for overheating in loft rooms and sun-facing spaces.
Reduces Heat by Up to 78%
The durable, transparent mesh fabric can reduce incoming solar heat by up to 78%*, depending on your glazing type. This helps:
-
Keep loft conversions cooler in summer
-
Reduce glare in home offices
-
Improve comfort in living rooms
-
Lower reliance on cooling systems
At the same time, the mesh design allows daylight to filter through and preserves your view to the outside.
Transparent Fabric with Privacy and Light Dimming
The anti-heat blind provides:
-
Light-dimming performance
-
Retention of outside views
-
Additional daytime privacy
-
Glare reduction for screen use
It is ideal for home offices, living areas and bedrooms where you want to reduce heat without darkening the room completely.
Easy Installation from Inside
One of the key advantages of VELUX anti-heat blinds is simple installation from inside the room. Both manual and solar-powered versions require no additional wiring, making them accessible for DIY installation or professional fitting by a VELUX Certified Installer.
This makes the anti-heat blind one of the most straightforward and cost-effective exterior heat protection options in the VELUX range.
Manual, Solar or Electric Operation
Choose the operation method that suits your window and lifestyle:
Manual (MHL)
Ideal for roof windows within reach. Installed and operated easily from inside the room.
Solar (MSL)
No wiring required. Powered by daylight and operated via remote control or compatible smart systems.
Electric (MML)
Recommended for electric VELUX roof windows. Controlled via remote or wall switch.
Solar and electric versions are compatible with VELUX Intelligent Home Control solutions, including VELUX Touch, VELUX App Control and VELUX Active with NETATMO (available as add-ons).
Combine with Interior Blinds and Insect Screens
VELUX anti-heat blinds can be used alongside:
-
Decorative interior blinds
-
Blackout blinds
-
Insect screens
This allows you to create a layered solution for light control, privacy and temperature management.
Rain Noise Reduction
In addition to heat protection, the exterior blind fabric can help reduce rain noise on your roof window, improving comfort during wet weather.
