“Rocksilk RainScreen Slab is a very popular

product within our Rocksilk range for external wall

insulation applications. It provides great thermal

performance, sound reduction capabilities and

it is a non combustible fire safe product, all

important considerations on urban developments.

Contractors also enjoy working with the product

as it’s easy to install and is designed to adapt to

a buildings minor imperfections. It is easy to fit

around the cladding support brackets and there’s

no need to tape the insulation joints making

installation easier.”

CHALLENGE

Westfield, the world’s largest listed retail

property company, is set to change the

face of retail in the United Kingdom

with the opening of its new flagship

development – “Westfield London” – at

White City, London.

Beneath a spectacular, undulating glass

roof, the £1.6 billion Westfield London

destination combines over 150,000m 2 of

retail, restaurants, cafes, bars and leisure

facilities to create the ultimate shopping

and leisure destination.

Westfield London will act as a catalyst for

the redevelopment and regeneration of

the wider White City area with a further

£1billion investment expected in the

immediate vicinity over the next 10 years.

installation benefits to both client and

specialist installing contractor.

Rock mineral wool has a Euroclass A1

fire classification to BS EN ISO 13501-

1, the highest classification available.

With rainscreen cladding incorporated

into building design fire performance

is particularly important and, as such,

a non-combustible component such as

rock mineral wool provides the ideal

prevention against the spread of fire. The

non combustible nature of rock mineral

wool ensures that it will not burn, will not

give off toxic smoke and will not suddenly

ignite in a fire due to ‘flashover’.

Another key specification element related

to the speed and ease of installation.

The required thermal performance of the

building was dependent on the correct

installation of the specified insulation

product. Rocksilk RainScreen Slabs are

easy to install down to their superior

workability ensuring installation stayed

within the tight time constraints. Rocksilk

RainScreen Slab is treated with a water

repellent additive to ensure the building

structure is protected against rain

penetration and it can also be installed

with either face adjacent to the sub

structure.

Rocksilk RainScreen Slab provides

an additional benefit for the installing

contractor as it is designed to adapt

to minor imperfections in the building’s

substructure. The rock mineral wool

product ‘knits’ together, ensuring intimate

contact between slabs ensuring all joints

are closed and thermal efficiency is

maximised.

Rocksilk RainScreen Slab has excellent

acoustic properties, which contributed

towards the acoustic performance of the

structure in order to comply with both

sound insulation and sound absorption

requirements.

What’s more, individual packs of Rocksilk

RainScreen Slabs are compression

packed together in Knauf Insulation’s

innovative packaging method, Supakube.

The advanced compression technology

and strong packaging materials ensure

the product is easy to transport and

store, reducing environmental impact and

causing minimal disruption on site and

the surrounding area.
