We offer lanterns as small as 800mm x 800mm and have built up to 18m x 7m clear spanning. Ventilation is provided from top hung fanlights, operated electronically or scissor hooks. The construction is of painted hardwood externally while the rafters (internally) are laminated clear redwood. The roof has a powder-coated aluminium capping to secure the glass and make it watertight. Glazing comes in the form of toughened clear sealed units as standard. A variety of embellishments internally are available, from panelling, decorative cornices, and turned pendants. Beautifully finished Westbury lanterns are a perfect solution to give light and ventilation combined with great architectural impact.
