EXTERNAL WALL INSULATION / REFURBISHMENT /

HIGH-RISE BUILDINGS /

High-rise buildings present a number of interesting technical challenges for the external wall insulation system designer. In addition to experiencing greater structural movement and higher wind suction forces than low-rise buildings, high-rise structures are riskier in terms of fire propagation, and are less likely to see regular exterior maintenance than their low rise counterparts.

The installation of an external wall insulation system to a high rise building is a longer process than with low-rise buildings, and the various elements forming the system may therefore be exposed for some time before the final rendered surface is achieved. It is important that façade systems for high-rise structures are designed with specific regard to these particular technical requirements.

PermaRock’s track record with high-rise is second to none, and our award winning systems have been designed to provide excellent thermal performance as well as total resistance to driving rain and high negative wind pressures. PermaRock systems are tough and durable, will withstand extremes of temperature and have very low maintenance requirements. But more than just providing systems that fulfil the technical requirements of high-rise buildings, PermaRock offers the widest choice of decorative finishes and effects giving the designer freedom of expression to create interesting and pleasing façades.

With high-rise buildings, the use of contrasting colour and texture enables the scale of buildings to be accentuated or diminished. Additional relief modelling, using extra layers of insulation or preformed insulation sections can be used to 'break up' the façade or to introduce curves into otherwise flat elevations.

PermaRock’s products and systems provide a totally flexible approach to rejuvenating high-rise buildings, combining good looks with practicality, satisfying the needs of the building owner and the occupants, the specifier and the installer.

The issue of fire safety is particularly important with high-rise buildings. PermaRock has a range of systems that offer the opportunity of CFC/HCFC free insulation that meets the requirements of Building Regulations and BS 8414 and can be designed for use on high-rise buildings without the need for fire breaks.

The PermaRock Mineral Fibre and PermaRock Lamella Systems are fire-safe during all phases of installation, not only after the final coat of render has been applied and are recommended for multi-storey buildings where optimum performance in relation to fire is paramount.

PermaRock systems can be applied to almost any substrate type, including brick, dense and no-fines concrete, blockwork, solid wall, cavity wall or panel (fair faced, exposed aggregate or ribbed) constructions. Where the building façade requires remodelling, perhaps by the extension of the external walls to enclose balconies using a lightweight metal frame, timber frame, or SIPS construction method, PermaRock systems still provide the optimum overcladding solution.

PermaRock systems are lightweight and easy to install from a traditional scaffold or from mast climbers. Installation is carried out by trained, specialist applicators monitored by PermaRock.
