We often get asked what the difference between a RoofLITE brand Roof Window and a VELUX brand Roof Window is. RoofLITE is made by a sister company to VELUX called Altaterra and are a cheaper alternative to VELUX windows. While both windows are of a high quality and are sure to flood the light into your home, we have made an easy to follow table detailing the main differences between VELUX and RoofLITE.

To makes things even we compared the VELUX Centre-Pivot MK04 (78cm x 98cm) in white painted pine with standard double glazing and flashing, to the RoofLITE AAX M4A (78cm 98cm) also in white painted pine with standard double glazing and flashing. 


Although there are some differences between RoofLITE Roof Windows and VELUX Roof Windows, both make great additions to any home and are both high quality roof windows. With a massive range of choices between the two different windows, there is sure to be something to suit your needs.
