Measuring & Installation Guide
When making a purchase, you should ensure that the size you are ordering matches the measurements for your external upstand (including any material for roofing). As an example, if you opt for the 1000mm x 2000mm roof lantern, then the measurements of your external upstand should also be 1000mm x 2000mm.
You should also ensure that the width of the upstand is 70mm minimum, with a height of at least 150mm.
As can be seen on the diagram below, there will be an overhang of 116mm between the roof lantern and the external upstand. The overall area the roof lantern covers for this example would be 1232mm x 2232mm.
Every Wendland roof lantern is made to order, and to your specifications. For this reason, please check the size you order carefully because once production commences, we will be unable to make any changes.

The fewest possible number of rafters are included in every Wendland roof lights lantern. Each one is made to measure and based on the specifications shown in the diagram below:
For rectangular roof lanterns, the width of the roof lantern can be made up to 3000mm and the length a maximum of 6000mm with at least 100mm variance between the two measurements.
The rectangular lantern skylight will be made as a double ended hipped design.
The square roof lantern can be made from 500mm x 500mm to 4000mm x 4000mm.
For both square and rectangular lanterns for flat roofs there is a 20 degree fixed pitch.
The design is produced with no gutter or glazing overhangs, and as a glazed 24mm sealed unit.
As standard, each Wendland skylight roof lantern will be designed with the fewest possible bars to maximise light distribution. If you prefer to have more roof bars included, or bars in any specific position, please get in touch with us before placing the order. This is because each roof lantern is made to your individual specifications and can’t be changed after production has started.
A 10-year manufacturer warranty is included as standard with the Wendland roof lantern.
Delivery & Lead Time
Production and delivery time for the Wendland roof lantern is 5-10 days.
Please ensure that on delivery there is a suitable person present who is able to unload the lantern glass roof lights from the lorry. The driver will be unable to assist in any way or deliver the items inside. This is due to insurance purposes.

When compared to Standard Neutral Glass, how much more heat does Celsius One Blue Tint glass retain?
Celsius One Blue Tint can help to slash your heating costs with its superior energy efficiency and thermal performance. It is capable of retaining 50% more heat when compared to the standard neutral glass, reducing your reliance on heating.

A comprehensive 10-year warranty covering seal failure applies to the Celsius glass range, and it is also certified to meet BS EN 12150-1 and BS EN 1279-2 standards.
Will the blue tint significantly reduce the glare I currently have in my conservatory? And how noticeable is the blue tint?
There is only a very subtle blue tone to the glass but the tint reduces the level of glare substantially without blocking the distribution of light throughout the year.
What is the best type of performance glass for my house that faces north?
Typically, a house with a conservatory that faces north would find more light extremely beneficial. For this reason Celsius Neutral Glass would be our recommendation. This glass provides the greatest amount of light without compromising the other qualities of the Celsius collection, such as superior heat retention.
If the opposite applies and you have a house which faces south, it will already be receiving lots of light so the Celsius One Blue Tint glass would be better to provide solar protection and to prevent glare.
