FAQs

Do I need to purchase anything else for installation?

Yes, the VELUX Fixed Flat Roof Window Base Unit requires a separate VELUX ISD Top Cover (flat, curved, or domed) to be fully functional and weatherproof. Blinds are also optional accessories.

What is the structural opening size required?

The structural opening required for this base unit is 1000mm x 1000mm.

Can this window be opened for ventilation?

No, this is a fixed base unit and cannot be opened. Ventilation must be provided by other means in the room.

What roof pitches is this unit suitable for?

This base unit is suitable for flat roof installations with pitches ranging from 0° to 15°.

How do I clean the window?

Clean the white PVC frame and the glass with a damp cloth and mild soap. Avoid abrasive cleaners. Ensure the exterior is free of debris.

What makes this window energy efficient?

It features ThermoTechnology™ insulation within the frame and low-energy glazing with energy coatings, which help reduce heat loss and improve thermal performance.

Is the laminated inner pane important?

Yes, the laminated inner pane enhances safety by holding together if the glass breaks, preventing dangerous shards from falling.

Troubleshooting

Condensation on the glass

Ensure adequate ventilation in the room. Check for any obstructions around the exterior frame that might impede airflow.

Water ingress around the unit

Verify that the VELUX top cover is correctly installed and sealed. Check the integrity of the flashing and roofing around the unit. Professional inspection may be required.

Reduced natural light compared to expectations

Ensure the interior surface of the glazing is clean. Confirm that no external obstructions (e.g., new construction, overgrown trees) are blocking sunlight.

Setup, Compatibility & Care

Setup: The VELUX Fixed Flat Roof Window Base Unit requires a structural opening of 1000 x 1000mm. Installation involves integrating the base unit into the prepared roof opening, ensuring a secure and weatherproof seal. Crucially, this base unit is incomplete without a VELUX ISD Top Cover (available in flat, curved, or domed styles), which must be purchased separately. Detailed installation instructions are provided by VELUX.

Compatibility: This base unit is designed to be compatible with all VELUX ISD Top Covers and a wide range of VELUX internal blinds, allowing for customization of light control and aesthetics.

Care: The white PVC frame is designed for easy maintenance. Clean the exterior and interior surfaces periodically with a damp cloth and mild detergent. Avoid abrasive cleaners to preserve the finish. Ensure the area around the unit remains clear of debris that could impede drainage.
