Application

To be used to the external façade of a patent glazing system in domestic projects, and can accommodate the following:


  • Roof glazing
  • Conservatories
  • Double and triple glazed applications (where compliance with Building Regulations Document L is a requirement).
  • Single glazing applications (such as feature canopies and unheated spaces).


This system is non-structural, and the glazing bar strength is provided by the internal structural timber rafters. The maximum span of the system is limited only by the integrity of the structural rafters specified – consult manufacturer for further details.


Typical applications include:


  • residential properties
  • schools, colleges and university buildings
  • hotels and leisure premises
  • social amenities including churches and community buildings.


Description

Flexible and attractive, the RafterLine Patent Glazing system is the most popular specifiers’ choice for domestic projects, such as conservatory roofs. 


Two edge supported patent glazing system with external extruded aluminium capping, for installation onto timber rafters (supplied by others).


Based on the same principles as the popular SkyLine Patent Glazing system but without the need for an internal stalk, RafterLine’s strength and visual appeal stem from the building’s structural timber rafters. As such, the maximum span achievable is only limited by the integrity of the rafters.  


RafterLine can accommodate single glazing, double and triple glazed units up to 50mm thick, including in settings where compliance with Building Regulations Document L is a requirement.


The rafters are protected from the effects of the weather by the external aluminium glazing system, avoiding the need for regular maintenance required by timber glazing systems, whereas the external glazing bar itself is made watertight protected by a screw on aluminium pressure cap with a choice of plain or ornate cappings to conceal all fixing screws.


As with all our systems, RafterLine can be combined with opening vents to offer a complete roof glazing solution and its user-friendly design and flexibility enable relatively speedy installation by a competent tradesman.  


The glazing bar extrusions and cappings can be supplied in unbroken lengths up to 7,000mm but can also be joined to create even longer downslope lengths. If necessary, RafterLine glazing bars can be ordered oversized for on-site cutting if exact sizes are not known at order stage.
