Cleaning InstructionsTile Removal / Replacement

Stage 1 Fixing wall brackets

Brackets must be chosen that allow for correct depth of insulation and minimum40mm air space between insulation and back of tile.

After checking tile layout drawings, using tape, string line or laser mark the primarybracket locations.

Drill bracket holes according to fixing type (avoiding concrete reinforcement).

Fix the Sliding Point brackets along rest of rail at centres determined by calculation,

bracket fixed using 1 anchor back to wall.(Picture 1) Fix the Fixed point brackets towards the top of the T1/T2 Vertical Rail, bracket fixedusing 2 anchors back to wall. (Picture 2)

Isolation pads to be placed between bracket and wall if required.

Anchors to be correct for wall type and calculated for dead load and wind load.

Carry out pull-out tests on anchors to ensure anchors work to applied loads.(hand brackets)

Stage 2 Fixing vertical rails

Using helping hand or clamp locate T1/T2 vertical rail onto primary bracket, eitherusing string line or laser ensure rails are in line and plumb(Picture 3)

Care must be taken to ensure that the rails are correct orientation for tile brackets,and that the predrilled holes on rails are in line.

The rails must be fixed correctly in height, elevation and vertical direction.

When rails are in correct position drill T1/T2 Rail at fixing location on primary bracket,at least 2 holes required for fixed point, single hole for sliding brackets(picture 4)

Using bolt, washer and nut attach rail to bracket, tighten to correct torque for type ofbolt (Picture 5)

After a number of T1 rails have been fixed check Rails for line and plumb(Picture 6)

Stage 3 Fixing Insulation

Check if insulation requires separate breather membrane or vapour barrier.

Ensure minimum air

Fix insulation to wall according to insulation manufacturer’s instructions.(Picture 7)

Example fixing instruction for Rockwool Rainscreen Duoslab

To obtain the optimum performance of the system, the Slabs should be applied with thepatterned side facing outwards. The resilient inner layer will accommodate surfaceirregularities.

Close butt the slabs at all vertical and horizontal joints. Stagger the horizontal joints ofthe insulation in accordance with good fixing practice.

Fix using a combination of metal and polypropylene fixings in accordance with the detailshown in Figure 1 inside the datasheet. Fixings should have a minimum head diameter of70 mm. Fix 6 polypropylene and 2 metal per insulation batt

Rainscreen Duo-slabs should be cut and tightly fitted around wall brackets where theseoccur.

Stage 4 Fixing Tiles

Slide up the PH2 tile Clip into position and fix using pin at base of on a numberof T1/T2 rails (Picture 8)

According to weight of tile use single man lift 20kg, 2 man lift to 40kgor use mechanical assistance above 40kg (check local Health &Safety requirements)

Place bottom nib of tile onto PH2 tile clip(Picture 9) , at same tile locate FP joint profileinto middle recess of T1 rail behind the tile(Picture 10)

Slide down PH1 clips onto top of tile and fix to T1 rail using pin. Ensure PH1 clip ispushed down onto top of tile and that tile is pushed against FP joint profileand that the back rubber seal is behind the tile(Picture 11)

Fix next tile above using same sequence.

When top tile has been placed onto PH1 clip, use PH2 clip without pin to secure topnib. (Picture 13)

Check both vertical and horizontal tile joint with straight edge to ensure tiles are in line.

Cleaning Instructions

Prior to handover please ensure that the tiles are cleaned.

If there is light dirt such as dust, the cladding panels can be cleaned with a dry cloth. Thisis especially recommended if only small areas are dirty. If bigger areas are dirty, thefacade should be cleaned with plenty of clear water.

In case of average dirt, the facade can be sprayed with a high pressure cleaner with a flat jet. If the facade is even dirtier, a detergent on soapy water basis can be used inconnection with a high pressure cleaner.

In case of extreme dirt such as oily stains, cement or mortar residue, paint etc., regularstain-remover or cement residue remover should be used if the a.m. cleaning methodsdo not work. First however, you should test how the material tolerates these products ona not so visible small area.

Important:

Mechanical devices such as a wire brush or steel wool may not be used for cleaning. Thiswould permanently harm the surface with scratches.

Tile Removal Replacement

To remove a tile push the tile above upwards, then push the tile to be removed upwards,this gives enough space to pull the tile to be removed by pulling the tile towards you anddownwards (Picture 14) .

A tile can then be pushed upwards into the PH1 Clip and then slid downwards onto thetop of a PH2 clip, the tile above is then pushed downwards(Picture 15) .
