For many
homeowners, the big consideration when it comes to the roof is insulation. And
while this of course can be an important aspect for keeping your house warm and
reducing energy costs, the reality is that neglecting roof ventilation can have
some serious, and costly, consequences.
Main Roof
Ventilation
In-line Slate Ventilators are ideal for roofs where the normal ventilation airpath is blocked by valleys, abutments, hips, dormer windows and firebreaks or party walls and for roofs where it is not possible to integrate standard eaves or ridge ventilation
An effective
method for delivering roof ventilation and keeping condensation at bay is by
adopting vents within the roof ridges or the eaves. As the warm air rises, so
the vents offer it a path to escape through the ridge, while eave vents can
draw colder air into the roof space from the outside.
Verge Trim
A Verge Trim
is a thin strip of plastic or metal that sits at the top of the wall where the
insulation meets the either the roofline or the windowsill. Verge Trim is
suitable for most situations where the external wall insulation requires
capping, whether around windowsills or at the top of the system to extend the
roof line. Its main purpose is to redirect water away from the EWI system and
prevent any moisture penetrating behind the insulation boards.
Ridges & Hips
Ridges
protect the top layers of slate and tile. If the ridge capping is blown off,
the top courses of slates or tiles can be quickly lost. Hips
and ridges are named after the purpose they were designed for: to cover your
roof’s hips and ridges.
Ridges: the horizontal lines at the top edge of two sloping roof planes.
Hips: the vertical lines
from two adjoined sloping roof planes.
Disc Rivets
Copper disc rivets are used for the fixing of roof slates, to avoid wind uplift of the slates, and preventing water from penetrating. Often used for moss prevention on roofs.
Benefits
- Copper
products help to minimise the effect of corrosion, as it is rust free
- Copper has
a very long-life expectancy, so you can trust the longevity of these
copper disc rivets
- Copper
has a life expectancy like that of lead
- Helps to
prevent the growth of moss and algae on the roof
- Hold
without restricting thermal movement of the roof
- Slate
roof protection
- Avoids
wind uplift
- Allows
slates to bend and recover under wetting and heating cycles
