This manually operated and enhanced noise reduction glazed GGL CK04 centre pivot roof window from VELUX offers an appealing white finish for clean and contemporary interiors. It is suitable for roof pitches between 15° and 90° and rotates 180°, meaning that cleaning from the inside is easy once it is secured into position with the built-in barrel bolt.
VELUX roof windows are comprised of several useful features. The ventilation flaps circulates fresh air when the window is closed, the high-quality pivot hinges make operation easy, and the pre-mounted brackets ensure that fitting blinds is almost effortless. Click on the blind, install the pre-cut side channels, and you're done. As for VELUX's innovative Thermo-Technology™, a lesser amount of energy is transferred, and rooms are kept cosy.
The (62) enhanced glazing includes three layers of glazing for up to 42dB of sound reduction and high thermal insulation. It is perfect for homes in colder locations that require extra shielding against outdoor noise. The glazing also features toughened glass for strength against external force, safety lamination to keep glass shards together if breakage occurs, as well as UV filters and great rain noise reduction. Homes are kept quiet and warm, furniture is protected from fading, and windows have less dew build-up with the anti-dew coating.
