| Insulating internal
and separating walls is usually undertaken to increase
the acoustic performance of the wall. This leads to
reduced sound transmission between separate areas of
a building - whether within a dwelling or between dwellings.
There are many reasons for the usage of insulation in
the construction of buildings.
- to comply with mandatory legislation i.e. Building
Regulations or Standards
- to reduce heat loss/heat gain
- to reduce running costs
- to reduce the risk of freezing
- to improve acoustic performance
- to provide condensation control
The industry now has many varied construction methods,
with many types of insulation available on the market.
So whether the application is a traditional cavity wall
or a modern external cladding system we are able to
advise on the type of insulation required and the standards
it will meet.
Fire protection is, naturally, a major consideration
in the selection of insulation. Buildings should be
constructed in such a manner that if a fire starts the
extent of the fire and smoke damage will be minimised
and kept as close to the source of fire outbreak as
is practical. The government has published 'goal based'
functional requirements in building regulations that
are supported by Approved Documents. There are no prescribed
methods, but fire resistant insulation is a route chosen
by many. Based upon the specifications of your project
we will gladly recommend the best materials to use as
well as give advice on installation.
A cavity closer provides a simple and efficient method
of closing a cavity in masonry without creating a thermal
bridge, and also forms a positive damp proof barrier
and plaster key. It effectively prevents condensation,
pattern staining and mould growth frequently associated
with traditional methods of closing cavities. A cavity
closer obviates the need for cut bricks or blocks to
close cavities and avoids problems encountered when
supporting traditional DPCs and insulation boards during
construction. We stock a broad selection appropriate
for a variety of openings as well as either timber,
metal or plastic window frames.
Insulated DPCs have been specially developed to minimise
cold bridges when closing masonry cavity walls around
openings. Insulated DPCs allow the cavity to be closed
in the traditional way whilst also conforming to current
building regulations. Insulated DPCs are designed to
be installed between the facing brickwork and closer
block work prior to the fitting of window and doorframes.
Most are self-supporting for ease of installation and
one width will cover most applications. Additionally,
many provide excellent sound insulation and are noncombustible.
