Access & Escape
Lumen conservation roof windows are supplied with Pilkington self clean double glazed units, a solid American oak interior liner and a brass hand mechanism as standard. However, we offer a variety of enhancement options including a choice of British made manual mechanisms, electric actuator options with rain and temperature control, a range of pleated blackout blinds, linking bars and access/escape rooflights options.
As with all our conservation roof lights, it is possible to detach our solid brass winding mechanism from the opening casement. In situations where an access or escape roof window is specified we can supply the Lumen LR4, LR5, LR6 and LR10 with variable force Nitro Struts. These rooflights are top hung to ensure a matching profile when used alongside our standard conservation range. As with all our opening casements, the access/escape rooflights can be used on a daily basis using the brass mechanism. We have designed our skylight to be top hung as these are less susceptible to light rain than side hung rooflights.
The variable force range of gas struts are supplied charge to the maximum pressure as standard and can be reduced as part of the installation process. These versatile struts are supplied with a black epoxy powder coated cylinder, black nitor carburized piston rod and have a working temperature range between -30°c to +80°c. The brass winding mechanism is supplied for daily use of the access/escape rooflight and we do not recommend using the struts for regular opening. When activated the struts will hold the opening casement open to allow access to the roof.
