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 Heat Protection Plus Blackout (DOP) – 2-in-1 Comfort Solution

The VELUX DOP 2-in-1 system combines two original VELUX products:

  • DKL Blackout Blind (internal)

  • MHL Anti-Heat Awning Blind (external)

Together, they provide total blackout and effective heat protection, helping you create the ideal sleeping environment while keeping your room cooler during sunny weather.

When purchased as this combined solution, you also benefit from a 10% saving on the MHL anti-heat blind.


Complete Blackout for Better Sleep

The internal DKL blackout blind delivers one of the most effective blackout performances available for VELUX roof windows. It features:

  • Light-proof seal for total darkness

  • Smooth manual operation

  • Integrated side channels

  • Ideal for bedrooms, children’s rooms and home cinemas

This makes the VELUX Blackout & Anti-Heat Blinds perfect for night-time use and daytime naps.


Exterior Heat Protection Reducing Solar Gain by Up to 76%

The external MHL anti-heat awning blind is installed on the outside of the roof window. By blocking direct sunlight before it reaches the glazing, it can reduce solar heat gain by up to 76%.

This helps to:

  • Reduce overheating in summer

  • Lower glare

  • Improve comfort in loft conversions

  • Maintain a cooler indoor temperature

Because it is positioned externally, it works more effectively than interior-only blinds when it comes to heat control.


Manual Operation – Inside and Outside

Both blinds in this 2-in-1 solution are manually operated.

Inside – DKL Blackout Blind
Operated using the integrated control bar, allowing flexible positioning anywhere within the window.

Outside – MHL Anti-Heat Blind
Manually operated with hooks, suitable for roof windows within reach.

Together, they provide simple, reliable control without requiring wiring or electrical installation.


Designed Exclusively for VELUX Roof Windows

This is a genuine VELUX combination solution, engineered specifically for VELUX roof windows. As original VELUX products, both blinds are precision-manufactured to ensure:

  • Perfect compatibility

  • Smooth installation

  • Seamless integration

  • Long-term durability

Avoid third-party combinations and ensure optimal performance with an authentic VELUX system.


Ideal for Bedrooms and Loft Rooms

The DOP 2-in-1 system is particularly suitable for:

  • South-facing roof windows

  • Loft bedrooms

  • Children’s bedrooms

  • Attic conversions

  • Home cinema rooms

It offers year-round versatility, combining summer heat reduction with complete darkness at night.
