FAQ Webshop Where do I measure to? All sizes quoted by Glazing Vision refer to the OVERALL EXTERNAL WEATHERED UPSTAND dimensions. The rooflights are manufactured with a tolerance for any variance in the surface of the upstand but care should be taken when measuring. If in doubt please contact customer services team: info@glazingvision.nl. Do I get a warranty with my rooflight? Yes you do, all Glazing Vision rooflights and access hatches are supplied complete with a two year warranty as standard. This is extended up to ten years with a GV install. Conditions apply. Do you install? Yes we do, all units are designed to be installed by trades or DIY enthusiasts but for buyers of our webproducts based in the Netherlands we also offer an installation service if you have any doubts. This does cost a little extra but sometimes it’s easier to let the professionals handle it and you also benefit from an extended warranty (10 years instead of 2). What do I have to think of concerning delivery? Your rooflight(s) will be delivered to your chosen site and date within five working days from the date of order. Deliveries will be made to kerbside or nearest accessible point, as most deliveries will be made using larger vehicles with tail lifts we may not be able to deliver to locations with restricted or narrow access. Please contact us if you are unsure. It’s necessary to have someone to sign for delivery when it arrives and inspect the consignment before signing for it. Can I collect? Yes you can collect your rooflight yourself at our logistic centre in De Lier (The Netherlands). A member of our team will contact you after your order has been placed to arrange a suitable time to collect your rooflight. Glazing Vision Europe Where do I measure to?
