The Keylite WCP01HT is a white painted timber centre-pivot roof window measuring 550mm by 780mm. It is designed to introduce natural light and provide controlled ventilation into loft spaces, extensions, and attics. The white painted finish provides a moisture-resistant surface, making the window suitable for a variety of environments, including kitchens and bathrooms.
Operating via a top-mounted slimline handle, the roof window pivots from the centre to allow for easy opening and closing. It includes a built-in trickle ventilation flap and an insect filter, enabling fresh airflow even when the window is securely locked. For exterior maintenance, the sash rotates 180 degrees, allowing the outer glass to be safely cleaned from inside the building. Installation is supported by pre-fitted Flick-Fit brackets and an integrated expanding thermal collar that expands to reduce cold bridging and heat loss.
The WCP01HT model features Hi-Therm glazing, which includes a 4mm toughened outer pane, a 15mm argon gas-filled cavity, and a 6mm laminated inner pane. It achieves a U-value of 1.3W/m²K to support current energy efficiency standards. The unit is compatible with pitched roofs ranging from 15 to 90 degrees and integrates with standard roof window flashings for a watertight finish.
- Made with an integrated expanding collar to combat cold bridging.
- Includes pre-fitted Flick-Fit brackets for faster installation.
- Features Hi-Therm double glazing with a 4mm toughened outer pane.
- Rotates 180 degrees internally for safe cleaning of the outer glass.
- Operates via a top-mounted handle providing secure trickle ventilation.
