Roofline System
New Build Applications
The Swish Roofline range includes all the necessary components for
eaves and gable assemblies, including fascias, bargeboards, eaves
soffits, as well as over fascia ventilation and protection. Matching PVC
mouldings cater for all joints, corners and abutments, which are sealed
after installation with Swish Low Modulus Silicone.
The range consists of Jumbo fascia profiles and accessories which are
available in three styles:

All Jumbo profiles are available in a wide range of sizes from 150mm
– 405mm depths and feature a groove for the engagement of soffit boards
by simple push-fit. Standard Jumbo profiles can also be used in ‘open
eaves’ situations where there is no soffit.
Fixing Methods
Because of its thickness and rigidity, Jumbo boards do not require a
supporting backboard. All Jumbo boards will provide support for the roof
covering at all roof pitches. This is subject to the boards being fixed
to rafter ends at a maximum of 600mm spacings using 2x65mm Trimtop
nails. Gutter brackets can be fixed directly to Jumbo boards using A4
stainless steel screws which should penetrate the inner face.

New Woodgrain-Effect Roofline Profiles
16mm Square fascia boards are now available in Mahogany, Light Oak,
Rosewood and Black woodgrain effect finishes. A range of ventilated
soffits, flat board soffits, corners, trims and fixings is also
available in matching finishes. For coloured profiles, centres should
not exceed 400mm.

Refurbishment Applications
Given sound existing timber fascias, bargeboards and rafters, a range
of Swish Roofline products is available which can be fitted directly
over the face of an existing fascia.
Cappair is an overcapping fascia, featuring a return leg which will
support a lay-on soffit board and has raised back ribs allowing it to
stand off the existing fascia. A series of offset grooves promotes the
free movement of air between old and new fascias, allowing moisture to
disperse where it would otherwise lead to rotting of timber.
Cappit profiles are mainly flat-backed for flush fitting to existing
sound fascias or backboards. Like Cappair, they have a return bottom leg
for lay-on soffits.
All overcapping profiles can be used in new-build applications but in
such cases will require a backing board of not less than 12mm marine
plywood.
Fixing Methods
Cappair and Cappit profiles should be fixed to the backboards with a
minimum of two 50mm Trimtop nails (C082) or 40mm Capped Screws (C072) at
centres not exceeding 600mm.
Square Edge Cappit profiles are also available in Anthracite and Grey.
For coloured profiles the fixing centres should not exceed 400mm.

Ventilation
Swish offer a full range of ventilation profiles which cater for the
requirements of both 10mm and 25mm air paths, in accordance with current
Building Regulations for England, Wales, Scotland and Northern Ireland.
Swish ventilators also meet the recommendations of the 1989 edition of
BS.5250:1975 which deals comprehensively with the subject of
condensation in dwellings.
The Polo range of ventilated soffit boards is available in a
comprehensive range of widths from 150mm – 605mm, in single slot
configuration for 10mm air path requirements or with a double row of
ventilation slots catering for 25mm air path requirements.
