VELUX in Europe has issued a product warning due to risk of spontaneous glass breakage in portions of its skylights sold in the past.

“We have registered a level of spontaneous glass breakage in a specific type of small pane produced and sold between 1997 and 2003,” according to statement on the company’s website. “Under specific conditions, generally experienced in the winter, there is a minor risk that the inner glass may break spontaneously, with the possibility of glass fragments falling. We take the quality of our products seriously and have decided to issue a product warning to inform our customers.”



  1. I have 2 Velux skylights in my holiday home and one of them shattered last year on the inside after a spell of cold weather. Can you tell me who should I contact regarding replacements please. My home is in Finea , Co. Cavan, Ireland. The number on the frame is 66L CO4 3000ea and is in lower rt corner. I dont know the number of the second one, but it was supplied and fitted by the builder at the same time,
    Thank You

  2. We are in New Zealand and recently our skylight was fitted in these years. It recently crackles and shattered them fell onto floor. Interested in knowing if you managed to get Velux to replace yours.
    Look forward to hearing from you.

    1. Ours just shattered too- in Boston area. It is hot here now, rather than cold. Did you have any luck in getting them to replace it?

  3. During a hot spell this summer one interior pane of a Velux skylight suddenly exploded. We have a total of 5 skylights and in 25 years have never had a problem.
    We are in Nova Scotia
    Is there any help available?
