Benefits of Heritage Rooflights:
Historic Character
Heritage rooflights have evolved from original glass structures from the Victorian era. Designed to keep the character of the building, heritage rooflights help conserve the property. Crafted from modern aluminium extrusions with high performance gaskets, they provide contemporary performance whilst maintaining the integrity of the building.
Natural Light
Continue to allow natural light to enter the building and reduce the use of artificial light and energy costs. Modern solar control and insulating units are available to improve thermal performance of heritage rooflights and traditional patent glazing systems are available for canopies or green houses and overhead glazing of unheated spaces. Other glass types can reduce solar UV helping to preserve valuable artefacts or furnishings in rooms below.
Ventilation
Different types of ventilators can be incorporated in either the upstands of heritage roof lanterns or the sloped areas of heritage rooflights. Various opening mechanisms can be specified including traditional pole or cord operated manual gears to modern thermostatically controlled electronic actuators, including remote and ‘smart’ operation.
Installation
Lonsdale are manufacturers only, so installation is carried out by a national network of registered contractors. Many of these are experienced at providing heritage rooflights on historic buildings and homes offering a high degree of professionalism and the extra finesse required to ensure a first class finished job.
