Which system to use?

Unheated Spaces, canopies, station and platform glazing SkyGard should be your first choice if using 6 to 7mm thick glass. If considering different glass thickness, then PlasGard would be your next choice

Heated Spaces
ThermGard is our thermally broken system providing excellent Uvalues and air-tightness when combined with insulating double glazed units for compliance with Building Regulations Part L.

Self-supporting Lanterns or SkyLights
SpanGard self-supporting rooflights feature extruded cill, ridge & hip members to provide you with a complete kit pre-fabricated upto 6m wide by infinite length without the need for additional support, other than a load-bearing curb.

If using Polycarbonate
PlasGard offers a range of glazing bars & accessories for use with ‘plastic’ glazing materials for unheated spaces. If you require a thermally broken system, then please see our ThermGard ALM500 Series

Rafter Glazing
If fitting glazing bars on top of continuous timber rafters, then section reference ALM100/WF suitable for single or double glazing from our ThermGard range, provides neat, low-profile appearance combined with excellent weather tightness and low-maintenance.

Need ventilation?
GlazaTherm roof vents can be incorporated in sloped glazing and fitted with manual, electric or smoke actuators. Alternatively we can provide casement vents in the upstands of lantern lights when required.

Patent Roof Glazing for Building"When it came to my own roof glazing project, Lonsdale proved to be the right choice "
– Sir Terry Farrell, Terry Farrell & Partners


Whether you are a home or commercial property owner, Lonsdale roof glazing systems are suitable for your building.

Whilst Lonsdale rooflights feature on some of our most historic and important buildings, we also like to lay claim to literally thousands of households throughout the country where our glass roofs are making homes more enjoyable to live in.

For those of you who wish to avoid dreary, cheap and cheerful plastic systems you may be pleasantly surprised just how competitive an aluminium and glass roof might be in comparison. Combining this with a 40 year design life and low maintenance, make Lonsdale systems the choice of discerning home owners, the Royal Family, Prime Minister and US Ambassador amongst them! If you choose to have a Lonsdale roof you will be in good company. Other well known people amongst our client list include leading architect Sir Terry Farrell, the Cartier jewellery dynasty, entrepreneur Sir James Dyson and top designer Jasper Conran.

Owners of commercial buildings can gain peace of mind knowing that Lonsdale remains the first choice of industry professionals and have been scrutinised by all the leading design teams including the likes of White Young Green, Atkins, Building Design Partnership and Davis Langdon.

Please see our list of recent projects where other building owners have chosen Lonsdale as amongst the best currently available.
