Maintenance tips for your Skylux skylight

Acrylic glass has a self-cleaning effect and requires little maintenance. Please do not use any cleaning products or solvents because they can damage the skylight. We advise using the Skylux-cleaner for the maintenance of your plastic skylight and the PVC-cleaner for the PVC frames and curbs.

Make your skylight last even longer thanks to these tips:

  • The skylight attachments and the sealing tape must be checked once a year.

  • Clean the skylight only with water and non-aggressive soap and rinse thoroughly with water after cleaning.

  • Please do not clean the skylights with products that are not suited for acrylic or polycarbonate. For example: no abrasives or aggressive products like silicone, wood protection products, adhesives, unsuitable sealing tape, chemical fumes, etc. These products can cause damage and will result into the loss of guarantee.

  • Remove tar stains only with turpentine and rinse thoroughly with water.

  • In case of scratches: please contact the supplier and ask for a suitable polishing product.

  • Do not use any insecticides on the skylight.

  • Metal and polyester curbs must be provided with an extra finish.
