Timber rafters, supplied by the builder or joinery sub-contractor, will create an appealing visual effect inside any building. These rafters are completely protected from the effects of weathering by our externally clad Rafterline patent glazing system.  This system offers superb weather resistance and eliminates the need for the regular maintenance typically required for traditional timber glazing systems.  The Rafterline system ensures that the beauty and integrity of the timber are preserved without the hassle of ongoing upkeep.

Due to the aesthetically pleasing combination of aluminium and timber materials, our Rafterline system has become the most popular choice among specifiers for domestic projects.  The blend of aluminium’s durability with the natural warmth and charm of timber creates a harmonious and attractive interior while providing robust protection against the elements.  This combination not only enhances the visual appeal of any space but also ensures long-lasting performance and minimal maintenance.  The Rafterline system is favoured for its ability to deliver both functionality and beauty, making it an ideal choice for a variety of architectural styles and applications in modern domestic construction.

Advantages

  • Unlimited spans achievable
  • Concealed capping fixings
  • ‘L’ Reg compliant
  • Thermally broken
  • Suitable for accepting opening vents
  • Very popular on domestic projects
  • Suitable for canopies/loggias/pergolas
  • Single, double or triple glazed options

Considerations

  • Accuracy required from joiner in rafter installation. If rafters are installed out of square then on-site templating and/or shaped glass may be necessary to rectify joiners errors.

The Rafterline patent glazing bar system is based on the same principles as the popular Skyline range.  The internal stalk of the bar in this case is not required.

The glazing bars’ strength is provided by others structural timber rafters x 50mm wide (44mm minimum) and the maximum span of this system is therefore only limited by the integrity of the rafters.

The glazing bar is weathered by a screw on aluminium pressure cap with a choice of plain (PC2) or ornate (PC3) cosmetic outer aluminium snap-on cappings to conceal all fixing screws.

The advantages of this system are that the timber rafters create an appealing visual effect inside the building and are totally protected from the effects of weathering from the elements.  The external aluminium glazing system will provide excellent weather resistance and is not subject to the regular maintenance required for timber glazing systems.

Due to the appealing internal appearance of this system, it is regularly requested for domestic use, such as conservatory roofs.  The Rafterline glazing system is suitable for double and triple glazed applications where compliance with Building Regulations Document L are a requirement.

This system readily accepts both single glazing, double and triple glazed units up to 50mm thick and as with all our systems, can be combined with opening vents to offer a total glazing solution.

The Rafterline glazing system is our most popular range of glazing bars on supply only contracts where the thoughtful design of our sections allows for relatively speedy installation by a competent tradesman.  The glazing bars can be ordered oversized for on-site cutting if exact sizes are not known at order stage however it is always preferable to order materials at the exact size tailored to your project.

Span Chart

Due to the Rafterline patent glazing system being non-structural the glazing bars’ strength is provided by others structural timber rafters and the maximum span of this system is therefore only limited by the integrity of the structural rafters. The glazing bar extrusions and cappings can be supplied in unbroken lengths up to 7000mm but can also be joined to create even longer downslope lengths.
