Janex Service

Short delivery times and a seamless, tailor-made service for refurbishment or new build projects that starts with professional design advice and doesn't finish when the windows and doors are installed, but follows through with aftercare, ensuring one organisation is responsible for the whole process of window and door supply.

Our installation teams fit to the highest standards and use the latest detailing and methodology - ensuring optimum thermal and air-tightness performance of the door in the wall structure.


A wide range of glass solutions are available. Our range has been developed to meet the future requirements of Code for Sustainable Homes and Passive House standards. This includes technical changes to materials and profile as well as new warm edge technology for glazing spacer bars and third generation low emissivity coatings to give superior insulation properties.
