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.
