The glazing bar is weathered by a screw on aluminium pressure cap (PC1) 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. |

Due to the Rafterline 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 stuctural 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.
