We
are the UK's leading installer of
Polyurethane Spray foam
Insulation
& Roof Insulation
We
can solve almost any roof insulation & condensation problem
with ease and at a very competitive price.
Polyurethane
spray foam is becoming widely recognised as one of the
most versatile and efficient forms of thermal insulation
around, achieving excellent u values from as little
as a 65mm thickness (0.35 W/m2K). A thickness of 130mm
can achieve a u value of upwards of 0.160 W/m2K, surpassing
building regulations in most cases.
Roof Insulation
Spray Foam (Polyurethane) is used for roof insulation
and is sprayed directly onto the surface where it bonds.
Besides being an excellent insulator, rigid polyurethane
foam is also very effective at preventing condensation
on metal roofs. The high density foam bonds and holds
tiles and slates in place: creating a seal to keep wind
driven rain and draughts out; conserving the heat energy
within the roof and instantly converting a cold roof
into a warm roof, all via our roof insulation system.

Spray Foam Roof Insulation
Websters provide a low cost yet very high performance
roof insulation system, known as
spray foam insulation. This type of roof insulation is a
rigid foam product, made on site
and applied by our team of highly skilled engineers. The
process is controlled
under the ISO 9001 Quality Control, meaning that all
materials used in the foam
are manufactured within the UK, applied using safe and
reliable equipment, and
the spray foam insulation itself achieves a certified
class 1 fire rating.
We
supply and install roof insulation, producing the foam
on site and transferring through heated lines to the
point of install, i.e the roof space, wall cavity etc.
Our work is carried out in keeping with all UK building
and trade standards with minimum disruption.
Having
over 30 years experience in sprayfoam, we have been
successfully sprayfoam insulating all types of property,
from house roofs and wall cavities, boats, agricultural
buildings and commercial premises, to large retail areas
and sports stadia.
Cavity Foam Insulation
If you have a building with a clear cavity then
polyurethane foam can be injected
to completley fill and insulate the cavity. No other
cavity wall insulation product
acts as a wall tie whilst still being the most thermally
efficient product in the
UK market. Our cavity wall insulation is BBA aproved, as
are our engineers,
following strict quality control regulations. Cavity
foam insulation is ideal
for brick to brick/block and random stone wall cavities.
Condensation Prevention
When airborne water vapour hits a cold surface, we get
condensation. This
particularly applies to metal roofs when the ambient
temperature is much
colder than the inside, i.e in winter. A coat of
sprayfoam on the inside of the
roof will prevent the water vapour condensating on the
surface by creating a
barrier between the cold metal roof and the water vapour
inside the roof space.
The foam itself will never get so cold as to condensate,
resulting in total
condensation prevention.
Car Park Insulation
Because the spray foam insulation bonds straight to a
surface, it removes the
need to affix insluated boarding, saving the cost of
having to mechanically fix
the insulation to the underside of a concrete soffit.
Insulated boarding typically
generates more waste as the boards are being cut to fit
on site, resulting in
off cuts which may not be useable. Spray foam car park
insulation offers the
same, if not better level of insulation as the market
leaders in insulated boards.
Spray foam car park insulation may be the best solution
if the duct / pipework / electrics
are already in situ, making it increasingly difficult to
install rigid polyurethane boards.
