ALTERNATIVE INSULATION MATERIALS
POLYURETHANE FOAM FOR BETTER INSULATION
Polyurethane foam can be used as a high performing insulant
for all types of new build or refurbishment project to meet or
exceed today’s standards. It is also widely used by architects
and specifiers for remodelling purposes, for instance in barn
conversions. When used for airtightness or stabilisation under
the roof or within the cavity it outperforms most other materials.
The sprayed or injected foam is not just an insulant – it can be
used for stabilisation purposes, for instance to hold tiles in place
for a stronger roof structure or to take the place of failing cavity
wall ties. The material can often be used when other materials
are simply not suitable. The material is so versatile that it can be
used in many different situations from buildings to boats!
For wall insulation, injected polyurethane foam can be used in
the cavity to provide a superior performing insulant which also
helps to bond the inner and outer leaves providing strength
to the building. Air leakage through the cavity can be reduced
to zero. Because of the greater thermal performance and the
reduced air leakage PU foam outperforms all other forms of
cavity fill.
It is a much less costly alternative to re-roofing and can be
applied to slates, tiles and other various roof coverings. It
permanently cures the problems of nail fatigue and makes the
roof much more resistant to storm or impact damage. Because it
is liquid when it is applied, it seeks and seals any unwanted air
leakage that may occur preventing the ingress of wind-driven
rain, snow and dust and dramatically reducing heat loss.
The foam also slows the deterioration of tile/slates by frost. On
the underside of the covering frost damage is eliminated. On
the weather side the frequency of the freezing/thawing cycle is
reduced. Slates and tiles will be less prone to damage by impact as
the foam distributes the forces.
When choosing a BUFCA registered installer, architects, builders,
and specifiers can be assured of the highest standards of quality
and service.

VECTAIRE’S WHHRS – VERTICAL
AND HORIZONTAL – CAN NOW BE
COMMISSIONED VIA AN LCD SCREEN
Web: www.vectaire.co.uk
Tel: 01494 522333
The upright units – the
Midis and the Maxis - offer
the option of an integral
LCD or a remote LCD
commissioning unit, whilst
the in-line EVO250 and
Mini can be commissioned
using a remote unit. The
commissioning engineer is
easily able to adjust unit
functions including trickle,
purge and boost speeds for
each motor, the length of
boost speed over-run time, the time delay before the boost speed
kicks in, holiday mode, night-time boost inhibitor times etc. The
user can see the speed at which the fan is operating, the relative
humidity, and when the filters need replacing. The user can also
set the unit to holiday mode for energy saving when the dwelling
is empty. These units are among the most innovative, efficient
and effective on the market today – and all are manufactured in
the UK.
