“Supplied by Sheffield Insulations
Manchester branch, Knauf Insulation’s Crown SteelTherm
Roll was ideal for this project. The product is
specifically designed for the thermal insulation of external walls
in steel frame construction, plus it combined the best qualities of
glasswool, such as superb thermal performance, sound absorption and
fire resistance.”

CHALLENGE
The challenge was made to Sheffield Insulations, supply chain
specialist, to find the right solution to meet Part L of the
Building Regulations requirement of the SBEM (Simplified Building
Energy Model) calculations. The solution also had to meet Part E
acoustic requirements as well as complying with the tight budgetary
requirements associated with BSF programmes. For public buildings
such as this, superior fire performance is crucial in line with
guidance offered by the recent Building Bulletin 100: Design for
fire safety in schools. The DfES (Department for Education and
Skills) also encourage designers to consider as many sustainability
techniques as they can in the design of new or refurbished school
buildings.
The innovative education village is the first project under the
Manchester School’s Programme with the aim of uniting the whole
community together to make the most of its facilities. The site,
due for completion early in 2009, will eventually house two
schools, providing pupils with high-tech classrooms, and an
environment conducive with learning.
SOLUTION
From the discussions with Sheffield Insulations, architects,
main contractor and Manchester City Council, Knauf Insulation
designed, manufactured and tested a new product solution,
‘Crown
SteelTherm Roll’ to act as a full fill insulant within the
steel frame cavity of the building. This cost effective solution
allowed for the reduction in the overall thickness of the wall
construction.
Now part of the generic specification for the wider project
being rolled out across 25 schools in the programme, Knauf
Insulation’s Crown SteelTherm Roll offers excellent
thermal performance. The inherent fire resistance of the mineral
wool insulation and it’s environmental credentials also contributed
to the specification.
Crown
SteelTherm Roll is manufactured in 600mm widths and is
specifically designed for friction fitting between standard steel
frame sections. The easy to handle roll is easily installed and as
the product naturally knits together there is no risk of gaps
between adjacent rolls or steel frames, adjoining rooms or between
floors, resulting in a thermal conductivity of 0.040W/mK, with no
thermal leakage.
Fully filling the studs ensured the passage of flanking sound
was dramatically reduced.
Crown
SteelTherm Roll is manufactured from glass mineral wool, which
is ideal for limiting the spread of fire - since it holds a
Euroclass classification A1, for non-combustibility and will not
burn. Nor will it give off toxic smoke or suddenly ignite in a fire
due to ‘flashover’.
Superior fire performance was crucial – and by specifying
non-combustible materials such as Crown SteelTherm Roll, Our Lady’s RC High
School is designed in accordance with guidance offered by the
recent Building Bulletin 100: Design for fire safety in
schools.
Crown
SteelTherm Roll is manufactured using recycled glass
bottles and is also recyclable at the end of the building’s life.
Free from CFCs, HCFCs and any other material with ozone depletion
potential in its manufacture and content the product also
represents no known threat to the environment.
