your blade your design

Use our online tool to create your perfect Blade Rooflight. As you choose from all the options, you’ll see your Blade Rooflight changing visually and also have a constantly updated price on screen so you can tailor your Blade to your budget and specification.

1. Select your glazing

You can choose between 'Double-A' and 'Triple-K' Blades. Double-A is double glazed with Argon gas and 'Triple-K' is triple glazed with Krypton gas. The overall 'combined product' Ud-Values are from 1.1 and 0.8 respectively. Centre pane u-values are 1.0 w/m2k and 0.4 w/m2k. Triple glazed units are not necessarily the best option in our temperate European climate when you allow for solar gain.

We're currently experiencing technical issues for our blades above 1500mm. For enquiries or quotes please get in contact at 01733 215564 or email us at info@ofset.co.uk

2. Enter your dimensions

Double-A Blades can be manufactured up to 3.36 m2 internal 'hole in the roof' sizes (4.88 m2 external product sizes) and Triple-K Blades up to 2.0 m2 internal sizes (3.17 m2 external). For cost comparison against other products it's best to compare external sizes as that reflects the 'actual product' size.

3. Select your frame colour

All Blades are painted to a minimum 60 microns for long term colour fastness. There is no extra charge if you choose from one of the six RAL colours below and only £110 extra if you choose an alternative standard RAL colour.

6. Optional bolt-on extras

Solar control glass bounces away heat from direct sunlight. Acoustic glass will reduce excess noise, although even our standard units will dampen sound extremely well as you have a super thick 10mm top glass pane. If you are concerned about additional security then you can change the bottom glass panel to toughened/laminated glass which can be up to 12.8 mm thick, the best in the business. Double and triple glazed units can give you a 'greeny' tint. Low iron glass helps reduce this affect and also for areas where there is low light it will allow more natural light to enter the building. If you do not require any of these optional extras simply click next.

7. Do you need a prefabricated insulated kerb?

All flat rooflights should sit on an insulated kerb with a minimum 5 degree pitch.
Order a ready made kerb below or create one yourself. Its your call.
