Codes For Roof Window Blinds: How to Choose the Right Replacement?

The Essential Guide to Roof Window Codes, Compatible Replacement Blinds and DIY Installation in Ireland

Replacing roof window blinds should begin with one essential task: identifying the correct roof window code. Unlike standard window blinds, roof-window blinds are designed to work with particular window models, size references and mounting systems. Selecting the correct code is therefore the foundation of a successful replacement.

For homeowners throughout Dublin and the Republic of Ireland, understanding roof window identification codes makes it easier to choose a compatible replacement blind, explore fabric options and complete an online purchase with confidence.

At Grays Window Blinds, our objective is to help customers take control of the entire process. By identifying the correct roof window code, choosing the appropriate blind and following the relevant fitting instructions, you can purchase your replacement online and undertake the installation yourself.

Whether you are looking for VELUX blinds in Dublin, Dakea BlocOut roof blinds, Dakstra BlocOut roof blinds, Fakro roof blinds, Keylite roof blinds, Rooflite roof blinds or Roto roof blinds, this guide explains what you need to know before placing your order.

You will learn how to locate the manufacturer’s identification plate, understand the information displayed on it, avoid common ordering mistakes and choose a replacement blind suited to your requirements.

Why Roof Window Codes Are Essential When Ordering Replacement Blinds

Roof-window blinds are not universal products. Although different manufacturers may produce windows with a similar appearance, their blinds, fittings and compatibility requirements can differ.

The manufacturer’s identification code helps establish which roof window you have and which replacement products may be suitable.

For example, VELUX roof windows use references such as MK06 and PK08 for particular window models and sizes. Older VELUX windows may display earlier codes, which can require consultation with the manufacturer’s replacement information. The official VELUX guidance explains how its identification plate provides the information needed to identify an existing roof window.

Dakea, Dakstra, FAKRO, Keylite, RoofLITE and Roto also have their own product identification systems. The exact information and its location depend on the manufacturer and window generation.

This is why choosing a roof blind based solely on its appearance is unreliable. A blind that appears suitable for one window may not be compatible with another.

The correct approach is straightforward:

1. Identify the roof window manufacturer.
2. Locate the window’s identification plate or type sign.
3. Record the complete code exactly as displayed.
4. Select a replacement blind that explicitly supports that window reference.
5. Review the product details and fitting instructions before purchasing.

Following these steps helps you make a more informed decision when shopping for roof blinds online in Ireland.

How to Find the Identification Code on Your Roof Window

The identification plate is the starting point for selecting a replacement roof blind.

On many VELUX roof windows, the type sign is located on the upper sash, behind the ventilation flap. The precise position can vary between models and production periods. Other manufacturers may position their identification labels differently, so consult the relevant manufacturer’s documentation if you cannot find yours.

Follow this process:

Step 1: Identify the manufacturer.

Look for the manufacturer’s logo or branding on the window. Do not assume that every roof window is a VELUX simply because it resembles one.

Step 2: Open the window according to its normal operating instructions.

Many roof-window identification plates are easier to access when the window is open. Follow the manufacturer’s instructions and take care to maintain a safe position.

Step 3: Locate the identification plate.

Check the appropriate area of the sash or frame for a metal plate, printed label or product reference.

Step 4: Record the complete reference.

Copy the information exactly, including letters, numbers and any relevant additional characters. Do not record only the part of the code that appears familiar.

Step 5: Keep a photograph.

Take a clear photograph of the identification plate. This makes it easier to refer to the information when browsing replacement roof blinds online or checking product compatibility.

If the plate is missing, damaged or unreadable, do not guess the code. Consult the manufacturer’s identification guidance or seek assistance before ordering.

Understanding Roof Window Codes: What Do the Letters and Numbers Mean?

Roof-window codes are product identification references. Depending on the manufacturer, they can identify the window type, size, product variant or generation.

The precise format differs between brands, so the same interpretation should not be applied to every roof window.

VELUX roof window codes

VELUX uses codes such as MK06 and PK08 for certain roof-window models. The complete reference may also include a window type, variant and production information.

For example, MK06 is a recognised VELUX size reference. It should be treated as an identification code rather than a product name for a blind.

Older windows may display references such as M06, 306 or other earlier-generation codes. These should be checked against the relevant official VELUX replacement information rather than automatically treated as interchangeable with current codes.

Dakea roof window codes

Dakea uses its own identification references. Its replacement guidance includes codes such as M6A, M8A and C4A for particular Dakea window models.

The existence of a similar-looking code in another manufacturer’s range does not establish compatibility. Always confirm that the replacement blind is intended for your actual window.

Dakstra roof window codes

Dakstra identification references should also be recorded exactly as shown on the original window.

Some Dakstra and Dakea window references may correspond within particular product ranges, but this does not mean every blind or mounting component is interchangeable. Verify the compatibility of the specific product you intend to purchase.

FAKRO, Keylite, RoofLITE and Roto codes

These manufacturers have their own identification conventions and product ranges. Record the complete reference from your window and use the relevant manufacturer’s information to establish compatibility.

If the code is unfamiliar, avoid selecting a replacement based on a partial match or an assumption that the window belongs to a standard range.

The essential rule: The window code identifies the window. You must then establish that the selected blind is designed for that specific window reference.

Choosing the Correct BlocOut Roof Blind

Once the window code has been established, you can focus on the blind itself.

Grays Window Blinds offers roof-blind options associated with several recognised manufacturers, including VELUX, Dakea, Dakstra, FAKRO, Keylite, RoofLITE and Roto.

BlocOut roof blinds are particularly worth considering for attic bedrooms, loft conversions, guest rooms and other spaces where reducing incoming daylight is important.

BlocOut Roof Blinds For Attic Bedrooms

In an attic bedroom, a BlocOut roof blind can help create a darker sleeping environment. This can be useful when the roof window receives early morning sunlight or when the room is used by someone who prefers reduced daylight while sleeping.

The performance of the finished installation depends on the blind design, fabric and surrounding arrangement. A blackout fabric does not necessarily eliminate every trace of daylight entering around the edges.

BlocOut roof blinds for loft conversions

Loft conversions often combine sleeping, working and leisure areas in a single space. Choosing the appropriate roof blind allows you to manage daylight according to how the room is used.

Consider the desired level of light control, the room’s colour scheme and the blind’s operating method before making your selection.

Choosing a fabric colour

Fabric colour can have a significant influence on the appearance of an attic room. Neutral colours can complement understated interiors, while aquamarine, muted blues, greens and other distinctive shades can introduce a more individual design feature.

Availability depends on the selected product and its fabric collection. Check the actual options offered for the compatible blind rather than assuming every fabric is available across every roof-window range.

Other considerations

Before placing an order, review the available operating system, fabric specification, product finish and supplied components. Ensure the selected product suits your intended use and is explicitly compatible with your roof window.

The priority is to establish compatibility first and choose the preferred design second.

Common Mistakes When Ordering Replacement Roof Blinds

Incorrect product selection can cause avoidable inconvenience, additional expense and delays. The following mistakes are particularly important to avoid.

Mistake 1: Assuming all roof windows are the same

Roof windows from different manufacturers can look remarkably similar. Their identification systems and blind compatibility requirements may nevertheless differ.

How to avoid it: Identify the manufacturer and use the complete window code when selecting your replacement.

Mistake 2: Recording only part of the code

A partial reference may not provide enough information to distinguish between different window models or generations.

How to avoid it: Copy the entire identification reference and retain a clear photograph of the plate.

Mistake 3: Confusing the roof window code with the blind code

The window and the existing blind may have separate identification labels. These references do not necessarily serve the same purpose.

How to avoid it: Identify the window first, then check the blind’s own product information if it is available and relevant.

Mistake 4: Assuming an older code is identical to a current code

Manufacturers may change their reference systems over time. Older windows can display codes that differ from those used on current products.

How to avoid it: Consult the manufacturer’s official replacement information. Do not assume that similar characters indicate an exact match.

Mistake 5: Assuming compatible window brands mean interchangeable blinds

Even where manufacturers offer products for comparable window types, that does not establish that their blinds, brackets or side channels can be exchanged.

How to avoid it: Confirm compatibility for the exact replacement blind rather than relying on the relationship between brands.

Mistake 6: Selecting a blind based on its appearance alone

A photograph may show a blind that looks suitable for your attic, but appearance does not confirm technical compatibility.

How to avoid it: Establish the window code and product compatibility before considering colour or style.

Mistake 7: Choosing the wrong blind category

A BlocOut roof blind, a standard roller blind and other specialist blind products serve different purposes and use different mounting arrangements.

How to avoid it: Select a product specifically intended for your roof window and your preferred light-control requirements.

Mistake 8: Ignoring the fitting instructions

Correct product selection is only one part of a successful replacement. The installation must also follow the instructions supplied for the chosen blind.

How to avoid it: Read the relevant fitting guidance before ordering and again before installation.

Mistake 9: Ordering several blinds without checking each window

A property may contain roof windows from different installation periods or even different manufacturers. Similar appearances do not guarantee identical references.

How to avoid it: Verify the identification code of every window individually before ordering multiple replacement blinds.

Mistake 10: Guessing when the identification plate cannot be found

Guesswork can result in an unsuitable product, even when the window looks familiar.

How to avoid it: Use the manufacturer’s identification guidance or request assistance with the available product information before proceeding.

Misconceptions About Roof Window Codes and Replacement Blinds

Misconception 1: Any blind labelled for a well-known roof-window brand will fit every window from that brand

The reality: A manufacturer’s range may contain different models, generations and compatible accessories. The exact window reference remains important.

Misconception 2: An older roof window cannot have a replacement blind

The reality: Older windows may still have compatible replacement options. Availability depends on the window model, its reference and the products currently offered.

Misconception 3: A replacement window code automatically confirms blind compatibility

The reality: Window replacement information and blind compatibility information serve different purposes. Confirm that the blind manufacturer or supplier supports your exact window reference.

Misconception 4: Every BlocOut blind offers identical light control

The reality: Performance depends on the fabric, product construction, mounting arrangement and installation. Review the specifications of the particular blind you intend to buy.

Misconception 5: You must arrange a home visit to buy a replacement roof blind

The reality: Where the correct code is available and compatibility can be confirmed, you may be able to identify and order a suitable replacement online. The key is having the right product information before purchasing.

Misconception 6: The old blind’s brand is always the same as the window’s brand

The reality: An existing blind may have been supplied by a different company. Identify the roof window independently rather than assuming that the old blind’s branding identifies the window.

DIY Roof Blind Installation: Read the Instructions Before You Begin

Once you have received the correct replacement blind, the next stage is installation.

Grays Window Blinds encourages customers to make use of its online fitting guidance and take an informed approach to installing their own blinds.

Before starting, locate the instructions for the exact product you purchased. Do not assume that a guide for a standard roller blind applies to a specialist roof-window blind.

Check that all supplied components are present, read the instructions in full and prepare the tools specified by the manufacturer.

Follow the installation sequence carefully, paying particular attention to the supplied fixings, side channels, brackets and operating mechanism where applicable. Do not modify the window or drill into its components unless the product instructions specifically require it.

Roof windows can be awkward to access, particularly in high-ceilinged loft conversions. If you cannot work safely from your available position, arrange suitable assistance rather than attempting an unsafe installation.

Once fitted, test the blind gently and confirm that it operates correctly without interfering with normal window operation.

Reading the instructions before beginning helps you understand the installation requirements and prepare properly.

The aim is to make the entire process manageable: identify the correct code, select the compatible blind, order online and fit the product yourself.
