Help & Useful Information

How do I find which Window Type I have?

VELUX Type Signs (Data plate) explained

Every VELUX roof window carries a unique Type Sign that details the type and size of the window. In most cases the Type Sign is located at the top right-hand of the sash, behind the control bar.

Type Signs differ in appearance depending on the model of your VELUX window. Please identify and select the version of Type Sign on your window from the illustrations below:

Step 1 - Locating the type sign.

In most cases the Type Sign is located at the top right-hand of the sash, behind the control bar.

Locating the Velux Type Sign

Step 2 - Finding the codes.

Depending on the year your window was produced you'll find one of the type signs listed below.

Roof Windows delivered after 01 April 2001 can be recognised by a grey coloured type sign with the type being three letters (e.g. GGL) and a size code made up of one letter combined with two numbers (e.g. GGL-M08)

Roof Windows delivered from 01 April 1991 to 01 April 2001 can be recognised by a golden type sign with the type being three letters (e.g. GGL) and a size code made up of three numbers (e.g. GGL 308)

Roof Windows delivered before 01 April 1991 can be recognised by a silver sign with the type being three letters (e.g. GHL) and size code made up of a numbers 1 - 14 (e.g. GHL 2)

Glazing Options

VELUX glazing provides heat insulation, sound insulation, added strength and safety – and protection from the elements. We offer a full range of glazing types to suit your particular needs. All VELUX glass units are AA fire rated. We recommend using laminated panes on all windows above head height. The inner glass in a laminated pane consists of two layers of ordinary float glass with a layer of plastic foil between. If the glass shatters, the shards are retained by the foil.

70 Pane

70 Pane - Laminated Safety glazing as standard. In case of breakage this prevents glass falling in to the room. U-value 1.3 W/m²K.

Eco-Lite Glass

*Note: This is not available for delivery, installation by Loft Solutions only. Made up of 4mm K-Glass low-E inner, with 4mm low iron external, these units have thicker glass than the genuine Velux units which use 3mm. U-Value 1.6W/m²K.

OBSCURE

34 Obscure Pane. U-value 1.1 W/m²K. Combines standard glazing with the inner pane obscured (Frosted). This makes it ideal for bathrooms as it provides privacy without reducing the amount of natural light. When ordering an upgrade from a pre-2001 window with a 16mm pane we will include the conversion kit to allow the 24mm glass unit to be installed.

62 Pane

62 Pane. Triple glazed glass unit with all the benefits of our 60 Pane further enhanced noise reduction plus enhanced energy efficiency and anti-dew coating. U-value 0.9 W/m²K.

PROTEC STAR

73 Pane. U-value 1.1 W/m²K. An improved version of our Standard 59 Glass unit, this glazing comes with a toughened outer and laminated inner pane. This makes it ideal for windows that are positioned above head height. As well as giving you extra protection against breakage, it has improved noise reduction, compared with the 59 standard Pane. It also comes with our clean and clear coating, which helps the window stay cleaner for longer. Ideal for high-level applications, which are hard to access for cleaning. When ordering an upgrade from a pre-2001 window with a 16mm pane we will include the conversion kit to allow the 24mm glass unit to be installed.

60 Pane

60 Pane - Noise reduction glazing. All the benefits of 70 pane, plus reduces traffic and other outside noise, including the sound of rain and hail. Easy-to-clean coating that repels dust and debris. U-value 1.0 W/m²K.

66 Pane

66 Pane. Triple glazed glass unit with all the benefits of our 60 Pane (except rain noise reduction) plus enhanced energy efficiency and anti-dew coating. U-value 1.0 W/m²K.
