Zappa natural slate façade from Komproment

ZAPPA is a natural slate façade system for covering existing as well as new buildings. The system is flexible

in terms of both visual expression and the level of thermal resistance.

ZAPPA façade system can be mounted directly onto the existing façade, on wooden frames or using

aluminium battens.

The natural slate for the Zappa system is supplied in three standard sizes, 200 x 400 mm, 250 x 500 mm

and 300 x 600 mm. Special sizes can be manufactured upon request.

The ZAPPA façade system is Cradle to Cradle certified at silver level. NOTE! The certification only applies to

system deliveries. Applies to Barcelona Plain and Barcelona Silver White slate only.

These instructions are prepared solely for façades mounted in Denmark, Norway and Sweden, on the basis

of installation on a wooden substructure.

Important!

Attachment between the substructure and the load-bearing building sections is not part of these

instructions and must fulfil the applicable standards and regulations at all times, as well as being

documented in the specific projects.

Receiving, Storing and Handling

Receiving procedure

An acceptance control must be performed

immediately after the goods have arrived at the

building site. If there are no objections to the

consignment note before it is signed, the goods

are accepted in the condition they arrive in and in

the quantity stated on the enclosed packing slip.

Storing and handling

All components should be kept dry and protected

against theft at the building site.

Pallets must always be stored on a level surface

and must not be stacked.

Disposal after use

The Zappa façade system is designed to be taken

apart and can be easily disassembled and reused.

See the accessories overview on page 5 to carry

out the correct sorting of waste.

8


Mounting principles

Façade

Zappa façade system has been developed for use

on façades. Natural slate is easily affixed to the

aluminium battens supplied with mounting clips

and mounted as a ventilated rainscreen according

to the two-step principle.

Roofs

Zappa façade system is not suitable for use on

roofs. Contact Komproment if you require roofing

solutions with natural slate.

Flatness tolerances for the underlying structure

Always check the underlying structure before

mounting spacers and battens. Straightness

requirement on the underlying structure, vertical

and horizontal, tolerance: +/- 3 mm, measured

with straightedge over 2 m.

Flashings All flashings around windows, doors, gables,

eaves, etc., in Komproment's standard drawings

and instructions are examples only. All flashings

must be reviewed, designed and planned out for

the individual project by the supervising architect

and/or consulting engineer.

Attachment Attachment to the load-bearing structure is not a part of these instructions and must always be documented and dimensioned for the individual project in accordance with current standards and legislation.

Details The drawings are not drawn to scale and are shown as principles. All structures must be designed for the individual buildings. Komproment cannot be held responsible for project design or for project details, which are the responsibility of the architect and/or consulting engineer supervising the project at all times. The dimensions provided are for guidance and must be checked at the building site.

Safety

As with all building materials, the safety

precautions for the machining of products from

Komproment are subject to the provisions in the

Working Environment Act.

It is recommended that:

Machining (cutting, grinding, drilling) of the

natural slate will release dust. Therefore:

• Avoid breathing in the dust by using a

tool with a dust filter

• Avoid contact with eyes and skin by

wearing personal protective equipment

• Avoid breathing in dust by wearing

personal protective equipment

• Ensure adequate ventilation at the

workplace

Sorting of natural slate

As natural slate is a cleaved natural product the

surface and thickness will vary, which is why the

following points are important to ensure the best

end result.

1. The slate must be sorted before

installation begins.

2. The slate is sorted into three thicknesses.

This could be done by colour marking on

edges that will be not be visible after

mounting, for example a colour code for

thick-thin slates.

3. Start by mounting the thickest slates

from the bottom up. (It is important to

always use the same thickness across an

entire row).

4. It is possible for around 2-5% of the slates

to be rejected before starting. With some

adjustments, these 'rejects' can be used

around windows/doors and edges.

5. Corners may be chipped on the slate, in

which case these slates should be

mounted so that the chipped corners

face upwards under the overlapping tiles,

if possible.

Machining of natural slate

To ensure the best result, it is important to have

the correct tools to adapt the natural slate. This is

done in different ways depending on the type of

slate being used. You can find a description of

how to adapt the slate below:

Barcelona Silver White and Plain

Machining of these slate types is always done

from the back, so that the front gets the same

chamfer as the other edges. We recommend

slate-cutting shears and a slate cutter/guillotine.

Autumn, Clouded Bay and Diamond Black

We always recommend cutting these types of

natural slate with a wet tile cutter/wet saw with

diamond blade.

General

Use a masonry drill bit or diamond drill bit to drill

holes in natural slate, do not use an impact

driver!

Important! Drilling and cutting dust must be

removed immediately after machining the slate,

as this can 'burn' into the surface.

Principal details Spacers

The wooden spacers from Komproment are heat-

treated. The heat treatment is a chemical-free

wood protection that improves the wood's

properties in terms of decay and weather

resistance.

The aluminium spacer from Komproment is a

100% inorganic spacer made from seawater-

resistant aluminium.

The spacers ensure ventilation and free passage

behind the façade (for ventilation and water).

The spacers are mounted vertically onto the

façade, max. C/C 600 mm.

Start at foundations (aluminium battens)

Against the foundation, place the starter batten

so the natural slate is the desired distance from

the terrain.

The façade cladding should be kept a suitable

distance from the terrain. Recommended = min.

150 mm.

Place the ventilated mouse guard strip under the

starter batten to prevent the entry of rodents

behind the façade.

The starter strip's additional depth ensures that

the natural slate has the correct incline.

Placement of first standard batten

The first batten after the starter batten is placed

over the starter batten with the following

distances:

X (see drawing):

For 200 x 400 mm slates: 120 mm



11


Batten distance

The system batten is mounted on the spacers using

the approved nails/screws.

For aluminium spacers, use 4.8 x 20 mm screws in

accordance with the component overview.

For wooden spacers and the underlying wooden

structure use 2.8 x 65 mm nails in accordance with

the component overview, centred in the spacer and

the underlying wooden structure.

Eyes/punches in the battens for clips are always

placed plumb over each other in consideration of

the running bond.

Batten distance (X1):

300 x 600 mm slates: 270 mm (6.17 slates/m2)



Mounting of slates

Divide up the slates starting at the centre of the

façade. The natural slate is mounted onto the

system batten one tile at a time using mounting

clips. The slates are always mounted in a half

running bond. The minimum slate width at corners,

windows and doors is 150 mm. If it is not possible

to maintain the running bond around windows,

doors and corners, this is established in the second

row of slates after the edge. Always mount 2 clips

per slate, even for slates down to 150 mm.

Mounting clips

Starter clips should be used for the lowest batten, 2

clips per slate. Starter battens/starter clips can also

be used over windows and doors to even out slate

thicknesses.

Standard clips should be used on the other battens.

Always use 2 clips per slate. This also applies to

small pieces of slate (slate ≤ 150 mm).

The slate is secured at the top of the clip and the

clip also holds the slate in the next row in place.

When using Zappa standard clips, always lay the

battens based on a 30 mm overlap.

If another overlap/batten distance is wished for –

please contact Komproment.

Due to the natural unevenness of the slate, it is

important that all slates are held in place by

the mounting clip to avoid 'rattling'. If

mounting a thin slate, you can squeeze the

mounting clip so that it fits onto the slate

better.

12


Placement of clips – 300 x 600 mm slates

It is recommended that tile clips are placed 150

mm from the edge of the slate for full tiles. The

clips should sit one above the other.

For placement of clips for 300 x 600 mm slate

tiles, see drawing.

Outside corners

Aluminium flashings for outside corners are

mounted on the spacers.

Nail or screw the flashings in place every 220 mm

along the full length. The slates and aluminium

battens are adjusted/mounted with approx. 5

mm distance to the aluminium flashing.

Examples 1, 2 and 3: The slate is adjusted in

towards the flashing.

Distance to flashing = approx. 5 mm

Example 4: The slate is adjusted to the outside

corner without using aluminium flashing. It can

help to make a template so that all the slates are

adjusted with the correct bevel.

Inside corners

Aluminium flashings for inside corners are

mounted on the spacers.

Nail or screw the flashings in place every 220 mm

along the full length. The slates and aluminium

battens are adjusted/mounted with approx. 5

mm distance to the aluminium flashings.

Example 1: The slate is adjusted in towards the

flashing.

Distance to flashing = approx. 5 mm

Example 2: The slate is adjusted to the inside

corner without using aluminium flashing. It can

help to make a template so that all the slates are

adjusted with the correct bevel.

Finishing slates over windows/doors

General: Mount the façade cladding over the

window with a min. 10 mm distance to the

window flashing. Adjust the slate where

necessary.

Use a starter batten over the window and starter

clips to offset the slate thickness.

Alternatively, when using small pieces of slate

over windows and doors, you can also use the

standard batten as it will not be necessary in this

case to offset a slate thickness.

Finishing slates under windows

General: Finish the natural slate/batten/spacer

under the window with a min. 10 mm distance to

the window sill. The window sill must also have

min. 30 mm extra room out over the façade

cladding. Adjust the slate at the top if necessary.

For whole tiles, finish with a standard aluminium

batten. For adjusted tiles, it may be necessary to

wedge the aluminium batten so that the slate is

ensured the correct incline.

Slate clips can be adjusted in accordance with the

drawing.

Finishing at the top (eaves/gable etc.)

General: Slates/battens/spacers are finished with

min. 10 mm distance to flashing/end of cladding

at the top. Also ensure ventilation of the façade

and the roof structure, if needed. Adjust the slate

at the top if necessary.

For whole tiles, finish with a standard aluminium

batten.

For adjusted tiles, it may be necessary to wedge

the aluminium batten so that the slate gets the

correct incline.

Slate clips can be adjusted in accordance with the

drawing.

16


Abutting joints of aluminium

profiles Horizontal aluminium battens

The horizontal aluminium battens are always

joined over a spacer, keeping a min. 3-5 mm

distance between the profiles for aluminium

tolerance.

The aluminium batten is secured with nails

/screws at all points where the spacers cross

(max. C/C 600 mm).

Aluminium battens are always finished with min.

10 mm distance to flashing, etc.

Vertical aluminium spacers

The vertical aluminium spacers are always joined

with min. 3-5 mm distance between the spacers

for aluminium tolerance.

Aluminium spacers are always finished with min.

10 mm distance to flashing, etc.
