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.
L04/E
With all of our standard conservation rooflights it is possible to detach the winding mechanism from the opening casement.

In situations where an escape rooflight is specified we manufacture the LR4 with preset Nitro Struts.

Our conservation escape version is top hung to ensure a matching profile when used alongside our standard range. As with all our opening casements the escape rooflights can be used on a daily basis with our winding mechanisms. We have decided to use a top hung version as these are less susceptible to light rain than side hung rooflights.

The LR4 escape can be used in the same roof pitch as our standard conservation product.

Regular access
If you wish to use the rooflight for regular assisted access, we can supply struts with a reduced capacity to assist with the opening and closing. Using a lower rated strut will render the rooflight unacceptable for escape purpose and the item must not be used as such. Please tell our team at point of order whether you require the rooflight for escape or access purposes.

Safety
For additional safety our Lumen LR4 escape rooflight utilises Econoloc gas springs. These positively lock when fully extended, protecting the operator from potential injury in the unlikely event of gas spring failure through overload or misuse. When the gas spring is fully extended a spring loaded locking shroud moves into place, preventing the gas spring from compressing.

In order for the gas struts to operate your Lumen escape conservation rooflight, you will need to pull the quick release pin on the manual winding mechanism. It is therefore essential that the winder is maintained on a regular basis and that the pin moves easily. Failure to do this may result on the pin sticking and the casement will not open fully.

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 -30c to +80c.

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.
