Installation, Insulation & Accessories

Shop a range of VELUX and Dakea accessories that will help with the installation and improve the performance of your roof window. An underfelt collar creates a tight seal between your window and felt underlay, whilst a vapour barrier will create an airtight fit that will prevent condensation. Use an insulation collar to improve the thermal performance of your installation.
