The ROCKPROFIL Cassette Systemis a dedicated

thermal insulation wall cladding system. It is recommen-

ded for use as a light prefabricated element for the exter-

nal perimeter and internal par tition walls of buildings.

The ROCKPROFIL Cassette System uses common metallic

elements load-bearing wall cassettes with stone wool

thermal insulation infill, covered on the external side

by sheet-metal cladding.

The ROCKPROFILCassette System is applicable as a curtain

wall element for steel or concrete load-bearing framed

structures without limitation.

The system can also be fixed to l oad-bearing walls and

beam fillings (for example large and/or heavy concrete

or aerated concrete panel walls, as well as to brick

or block masonry). It can be used as both a ver tical

and horizontal cladding with an external sheet-metal

aesthetic.

Overview of the ROCKPROFILE

Cassette System

The ROCKPROFIL Cassette System

is similar to traditional cassette walls,

but it has the added advantage

of reducing linear cold bridges

at cassette noses. This, in turn,

reduces the total thermal loss

of the wall.

The ROCKPROFIL Cassette Systemis therefore suitable

everywhere there is a requirement for a low heat transfer

coefficient (U value) as par t of an overall narrow build

depth ie. a slim total wall thickness.

Its use is also highly appropriate for cladding walls

where the specification is to fulfil an ambitious level

of heat transfer coefficient its application minimises

the energy requirements for heating buildings. In addition

to these key features specific to the ROCKPROFIL Cassette

System, are all the other beneficial properties of traditional

cassette curtain walls simple and reliable systems,

productive and variable assembly possibilities, good

acoustic properties, a small number of standard

components yet with the option to choose different

claddings on the external wall side. Further, this system

is very economical to install and maintain, providing

a good return on investment costs.

Because the ROCKPROFIL system suppresses the effects

of cold bridging, the stone wool thermal insulation therein

performs around 40% more efficiently than an equivalent

quality and thickness of insulation within a traditional

cassette wall.

description

The ROCKPROFIL Cassette System has been specially

designed to prevent is cold bridges at cassette noses with

the help of overlapping stone wool thermal insulation

batts, inserted within thecassettes. While the load-bearing

cassettes and external cladding elements are standard

ones, the fixings for the external cladding are special

distance fastening screws. These are anchored to cassette

noses while, at the same time, being able to secure

a cladding element at 40 mm distance from the cassette

nose. The insulation component is a single layer of multi-

purpose stone wool batts which provide thermal, acoustic

and fire resistant protection to the structure.

The installation format allows for the insulation layer

to be inserted into the cassette while also forming a 40 mm

overlap covering the cassette noses. This arrangement

eliminates air gaps at all the horizontal joints of the

insulation batts. In essence, the ROCKPROFIL Cassette

System comprises standard components with the exception

of a few specified named products. It is regarded as an

open system, especially suited for the use of different

external cladding options (trapezoidal and corrugated

metal plates, external cassettes, non-metallic combined

tabular claddings onto system grids etc.).

basic components

1.Horizontal zinc-coated steel load-bearing cassette,

generally varnished, height 600 mm, depth H (mm)

sealing, fastening and fixing accessories for cassette.

2.Plinth supported or top suspended continuous steel sheet-metal element (protecting against vertical

displacement of cladding hanging down). The special

fixtures ensure its static performance with the cassettes,

plus its regular prole of zinc-coated steel with a minimum

thickness of 1.25 mm. This element defines a fixed

point for the cladding from which thermal movement

is accommodated as vertical cladding elements expand

or contract. It is best to suspend supporting elements

by fixing from the warmer top end on buildings where

significant thermal movement is anticipated.

3.Thermal insulation batt Airrock ND (for the ROCKPROFIL

System), size 610 mm x 1,000 mm x (H + 40) mm. There

is an option for the batt to be produced with a black

glass fleece on the visible front face (suitable in the

case of opaque or other visible over cladding) or on the

rear face (in the case of acoustic perforated cassettes);

insulation batt with non-woven texture is marked

as Airrock ND FB1 (for the ROCKPROFIL System).

4.Distance screws SDC2-S-S16-5.5 x 63 mm (stainless

steel) or SDC2-T-A16-5.5 x 63 mm (heat-treated carbon

steel) with sealed washers made by SFS Intec for fixing

vertically oriented external sheet-metal plate to cassette

noses at a flat or slightly curved low wave position (for

instance sinusoidal corrugated plates).

A. For vertical external cladding

5.A. External formed sheet-metal cladding, for zinc-coated

steel with minimum thickness of 0.75 mm, fastening

accessories for the external formed sheet-metal

cladding (for longitudinal seams and plinth supporting/

top suspended profile).

6.A.Elements of tinsmith-external cladding completion.

7.A.Supplementary facade components (ventilation grids,

shutters, sealing collars etc.).

B. For horizontal external cladding

5.B. Vertically mounted grid of zinc-coated steel (eventually

varnished) with OMEGA-shape profiles anchored

to cassette noses at load-bearing locations by two

distance screws SDC2-T-A16-5.5 x 63 mm (heat-treated

carbon steel); regular OMEGA profiles with minimum

steel thickness of 1.00 mm, with minimum height

of 40 mm, oriented in such a way that their flanges lie

on the surface of the overlapping stone wool insulation

Airrock ND (for the ROCKPROFIL System).

6.B. Other external cladding components according to the

construction design, standard fixing to the OMEGA

profile.

Note 1:For roundsheet-metal formed plates with low wave or for achie-

ving of greater aesthetic effect of the external cladding, it is possible to

replace the basic distance screws with hexagonal head SD C2-S or SDC2-T

screws which have an attractive so-called irius ??? appearance with teeth

under the head L12 -marked as SDC2-S-L12 or SDC2-T-L12. For rapid and

high-quality assembly of all SFS Intec screws, special self-locking adaptors

made by SFS intec are recommended (type E 480 for hexagonal heads

and E 420 for L12 irius heads), which are attached by renewable jaws.

Note 2:Continuous steel sheet-metal plinth supported or top sus-

pended prole (protecting against vertical displacement of clad-

ding hanging down) ensures xing to ver tical OMEGA grid and

its static performance with cassettes, regular prole from zinc-

coated steel with minimum thickness of 1.25 mm. This element

denes a xed point of the cladding from which the vertical

grid can expand. The most suitable placing of supportingelement is at the warmed-up attic.

The ROCKPROFIL Cassette System has superior fire performance when

compared to the behaviour of traditional cassette walls with corresponding

parameters (eg. the same cassette depth and metal plate thickness, the same

thickness and quality of stone wool insulation, the same external sheet-metal

cladding). Test results for the ROCKPROFIL System according to EN 13501-2 are:

E 120 (io); EI 30 (io); EW 60 (io); E 120-ef (oi); EI 30-ef (oi);

EW 60-ef (oi). More details on fire classifications are available upon request.

During a unique fire demonstration in Mokrsko (CZ) month/year?, a testbuilding was erected and set on fire especially to show the excellent fire

protection performance of the ROCKPROFIL System.

The first group of conditions relates to the specific

components used:

a) External formed sheet-metal plate (trapezoidal

or corrugated) must be from zinc-coated steel

of minimum thickness 0.75 mm (or with regard to

stiffness, of equivalent aluminium plate or aluminium

alloy plate, e.g. minimum thickness of 1.00 mm).

b)For the assembly of vertical metal plates or secondary

vertical grid for horizontal or oblique external claddings,

only the recommended type of SDC-2 screw made by

SFS intec should be used.

c) Thermal insulating properties declared in this Assembly

Manual refer only to the recommended insulation material

Airrock ND (for the ROCKPROFIL System) with a 40 mm

overlap of insulation over the cassette nose. In addition,

any further or nondescript mouldings, Z-profiles, grids,

other structures or components shall not be inserted

in the area of the facade which includes the overlapping

insulation.

d) There is a reduction of the static properties of load-

bearing cassettes in the ROCKPROFIL Cassette System

Compulsory Conditions

for a Guaranteed Application

by comparison with the static properties of the same

cassettes when applied in a system comprising straight

fastened vertically clad trapezoidal metal plates secured

by short screws through the separation tape (so called

classical cassette curtain wall). Under the same static

scheme, factors determining the reduction in load-bearing

capacity are the cassette type used, its metal plate

thickness, external cladding sheet-metal thickness and

the spacing system of the distance screws. It is necessary

to check the potential static performance in collaboration

with the manufacturer, the supplier or the cassette importer.

The second group of conditionsconcerns the instructions given

totechnical staff and the practical

training of construction crews who

will be personally participating

in the pre -assembly operation or

the mounting installation on site.

Besides its thermal and fire protection capability, ROCKPROFIL also provides

excellent acoustic properties. These were measured in CSI Prague month/year?

on actual model buildings giving results for weighted laboratory air-borne

sound reduction Rwup to 45 dB.

Note:All stated acoustic parameter measurements have been taken e according to internationalISO standards and the accredited testing reports for an actual project are available on request.

Thermal insulation properties

Preparation of external metal sheet cladding

The thermal protection of the building is one of the

most important characteristics for designers to consider.

A ROCKPROFIL Cassette System specification makes it

possible to achieve a first-class energy-conserving building

envelope and save costs for heating. Actual thermal

performance values were measured in a Weiss air-condi-

tioning chamber by standardised methods. From two

measurements with total insulation thicknesses of 155 mm

and 175 mm, an accurate interpolation and extrapolation

was made for insulation thicknesses from 120 to 200 mm.

The ROCKPROFIL Cassette System has reduced static para-

meters compared to so-called traditional cassette curtain wall

systems with straight assembled vertical trapezoidal metal

plates using the same cassette, insulation and trapezoidal

metal plates. This is due to the performance of the longer

fastening screws. Reduction coefficients of load-bearing

cassette capacities are established by combined experimental

and calculation methods. These coeffi cients are dependent

Short description of installation

1.Install the load-bearing cassettes of the specified type

it is recommended that the cassette nose for the first

cassette at the lowest level (if it is convenient) be cut off.

Assembly

manual

The Assembly Manual briefly describes basic operations

and presumes background knowledge of metal cladding

components, building ironmongery and the work of the

insulation contractor in the assembly team. Prior to the

cladding installation, the construction site must be

adequately prepared and surveyed. Scaffolding will need

to be erected, components supplied and the contractors

will study the projects design documentation.

The detailed Assembly Manual is available upon

request.

2.Prepare and mount the supporting profile.

3.I nsert Airrock ND from the top downwards and cover

the cassette noses. Staggering the rows of insulation

batts is necessary at cassette noses to prevent the

formation of vertical gaps, thereby providing complete

thermal integrity.

4.Mount header and reveal joists at windows, doors

and gates and install all flashing components that

cannot be bedded in after the external cladding has

been fixed.

5.Fasten the vertical external metal sheet or OMEGA

profiles according to the building design using screws

SDC2 S S16 5.5 x 63 mm.

6.Continue the assembly according to the facade

diagram and instructions for installation.

Static Parameters

on metal plate thickness and width, cassette nose shape,

and the pattern of distance screws etc. Detailed data must

be determined by the designer with help from the cassette

supplier and taking into account the inuence of load to the

building from external forces (for instance from wind), height

and shape of the building, the surrounding terrain and any

other relevant local site conditions. More details about these

parameters are available upon request.
