VELUX Centre-Pivot Roof Windows White Painted 55x98cm GGL CK04 2062

Typical applications and installation

This roof window is best suited to bedrooms, home offices, and other noise-sensitive rooms where external sound reduction is a priority. The 55x98cm (CK04) size fits standard roof pitches and rafter spacings. Installation should be carried out by a qualified installer to ensure proper flashing, insulation, and weatherproofing. The top-operated mechanism is particularly valuable in rooms where wardrobes, beds, or other furniture occupy wall space, as it eliminates the need for clear floor space in front of the window.

  • Ideal for bedrooms and quiet zones in noisy locations
  • Suitable for properties near roads, railways, or airports
  • Fits standard CK04 roof window openings (55x98cm)
  • Top operation works with furniture positioned underneath
  • Professional installation recommended for proper weatherproofing

Operation and cleaning

The window opens and closes via the top control bar, which provides intuitive operation without requiring access to a lower sill. The centre-pivot design allows you to rotate the window 180 degrees, enabling safe cleaning of the outer glass from inside your home without needing external access equipment or scaffolding. This is particularly valuable for upper-storey installations or difficult-to-reach roof positions. The removable and cleanable ventilation filter should be checked regularly and cleaned or replaced as needed to maintain airflow and protect against dust and insect ingress.

  • Operate via top control bar – no lower sill access needed
  • Rotate 180 degrees for safe external glass cleaning from inside
  • Remove and clean the ventilation filter regularly
  • Filter protects interior from dust and insects whilst allowing ventilation
  • Ideal for properties where external access is difficult or unsafe

Sound reduction and ventilation

The special sound-insulating glazing and extra sound reduction features work together to minimise external noise transmission. This makes the window particularly effective in reducing traffic noise, aircraft noise, and general urban sound pollution. The window maintains a removable ventilation filter that allows fresh air circulation whilst protecting your home from external dust and insects. This balance between noise reduction and ventilation is essential for maintaining healthy indoor air quality in noise-sensitive locations.

  • Special glazing reduces incoming noise from traffic and external sources
  • Extra sound insulation engineered for high-noise environments
  • Ventilation filter allows air circulation whilst blocking dust and insects
  • Maintains indoor air quality without compromising noise reduction
  • Particularly effective in urban and transport-adjacent locations

Maintenance and upgrades

Regular maintenance involves cleaning the glass and checking the ventilation filter for dust and debris accumulation. The window can be upgraded with remote-controlled operation using either mains-powered or solar-powered motors, which adds convenience and allows operation from anywhere in the room. Blinds can be quickly and easily fitted using the pre-fitted brackets, allowing you to control light and privacy without additional installation work. All moving parts should be kept clean and free from obstruction to ensure smooth operation.

  • Clean glass regularly and inspect ventilation filter monthly
  • Replace or clean filter as needed to maintain airflow
  • Optional mains or solar-powered motor upgrades available
  • Blinds attach quickly to pre-fitted brackets for light control
  • Keep pivot mechanism and control bar clean and unobstructed
