EXTERNAL WALL INSULATION /

EXISTING BUILDINGS /

For many existing buildings, the thermal performance of the external walls falls well below the standards required by current Building Regulations with heat energy losses through the walls being of an unacceptably high level by today’s standards.

Many buildings were designed without any form of insulation in the walls, and even those buildings with cavity walls which have subsequently been fitted with cavity insulation can fail to meet the stringent thermal performance requirements of the current Building Regulations and Decent Homes Standards. Many existing buildings also suffer from cold bridging and the associated problems of dampness and condensation which can have health implications for building occupants.

Building owners are also faced with ever increasing costs for heating and maintenance whilst at the same time being asked to reduce energy consumption in support of global efforts to reduce CO2 and other greenhouse gas emissions.

Reducing heat energy losses through the external envelope and eliminating problems associated with condensation and dampness is a key issue for both social housing and for commercial redevelopment, for high-rise and low-rise, traditional and non-traditional forms of construction. Complete remodelling of the building façade is also possible with PermaRock.

The wide range of decorative finishes and effects that are available with PermaRock systems provides the designer or specifier with the means of creating interesting and aesthetically pleasing façades that either compliment the original style or which can create a whole new impression.

PermaRock systems are available for all types of construction, including solid wall or cavity wall, concrete, steel or timber frame, dense and no-fines concrete, brick and stone, rendered, metal clad, tile clad or timber clad structures. PermaRock systems have been designed for use on high and low rise buildings, for traditional and non-traditional forms of construction, including many pre-cast reinforced concrete (PRC) types, in exposure conditions ranging from sheltered to very severe.

PermaRock systems can achieve very high standards of thermal insulation, not only up to current Building Regulations requirements for new buildings but also beyond predicted future energy-saving and CO2 - reduction requirements: PermaRock systems can be designed to meet or exceed any future reduction in Uvalues that may be imposed.
