INSTALLATION RECOMMENDATIONS SIDERISE RH25(G/S) ’Open State’ horizontal cavity barrier for maximum 25mm ±3mm air gaps These cavity barriers are installed in the void formed between the rainscreen facade and the inner structural wall, using the appropriate screw fixings or SIDERISE support brackets

Tools- for installing SIDERISE CW-FS ,Snips , Long-nose ,Pliers- Sharp Knife ,Straight Edge, Soft Serrated Blade Hand Saw which cuts through mineral wool insulation

Sequencing (arrange in a particular order) 1.RV Vertical Cavity Barrier, 2.RH ‘Open State’ Horizontal Cavity Barrier, 3.Thermal Insulation

Fitting -RV Cavity Barriers MUST take priority over RH Install abutting cavity barriers tightly together making sure there are no gaps.

Taping – RV- SIDERISE foil tape RFT 120/45. Apply SIDERISE RFT Foil Tape to both sides of the cavity barrier joint. You do not need to tape to the wall and the front face of the RV but you can do

RH 25 = Horizontal ‘Open State’ Cavity Barriers are suitable for 25mm air gap Checked Project Spec 25mm ±3mm air gaps

RV = Vertical ‘Full Fill’ Cavity Barriers- Checked Project Spec Inspection of vertical-cavity barriers (FB) FULL FILL CAVITY BARRIER TO SUIT CAVITY, +10 mm compression check project spec

Measuring SIDERISE RV Cavity Barriers must be installed under compression. Measure the void size at two places, add 10mm to the measurement. Measure void, add 10% compression allowance. Correct compression = wrinkled foil

Brackets RV Method 1, 1. Bend Brackets set at 600mm 2. Fix to wall 3. Install RV must penetrate the firestop by 75% at mid thickness, using non-combustible fixings at 600mm centres, Making a small incision at bracket locations is required

Brackets – RV Method 2-1. Bend Brackets 2. Fix to wall Horizontal the brackets & fixings is visible 3. Install RV must penetrate the firestop by 75% at mid thickness, using non-combustible fixings at 600mm centres, Making a small incision at bracket locations is required

Brackets RV Centres: 2 brackets are required per length, at nominal 600mm centres, 1 bracket is required if the cut length is 300mm or less. 2 Brackets required if the cut length is 301-1200mm

Brackets – RH The Brackets must penetrate all the way through the cavity barrier at mid thickness. Use a sharp knife to make incisions into the cavity barrier both front and back. Insert the brackets into the cavity barrier. Trim split leg to 10-20mm using snips. Bend split leg in opposing directions using long-nose pliers making sure the bracket is holding the cavity barrier tight but not overly tight

Brackets – RH- Centres 3 Brackets are required per length, nominal 400mm centres. 2 brackets are required per length between 100mm and 800mm. AVOID lengths less than 100mm.

Fitting – RH Align the cavity barrier in location making sure it is straight. Install abutting cavity barriers tightly together making sure there are no gaps

Taping – RH Apply SIDERISE RFT Foil RFT 120/45. the top side of the cavity barrier joint. You do not need to tape it to the wall. You must not tape the front face of the RH. Apply SIDERISE RFT Foil Tape to both sides of the RV to the RH cavity barrier joint. Apply SIDERISE RFT Foil Tape to inside and outside of the RV to RH cavity barrier corner joints around openings.

Taping – Openings - SIDERISE foil tape RFT 120/45. Apply SIDERISE RFT Foil Tape to inside and outside of the RV to RH cavity barrier corner joints around openings.

Details – Corners Corner joints should be mitred to ensure a continuous line of intumescent. 1.Cut a triangle from the back of the RH to suit the shape of the corner 2. Fold the RH into an “L” shape and apply SIDERISE RFT Foil Tape to the top and bottom of the RH; NOT the front face 3. Install brackets into RH then fit to the wall. 4. Make sure a tight radius is maintained so the corner is not rounded.

Details – Rails Any rails intersecting the cavity barriers can be notched around. Make sure the cavity barrier is tight around the rail, if there are any gaps, pack with RV/RH offcuts and seal wising SIDERISE RFT Foil Tape. If there is a rail in front of the RH and there will be a gap between the front face of the rail and the panel, either use an OSCI or fix an intumescent strip to the rail front face

Details – Small Voids RV If the void size is less than 50mm, you do not need to use brackets with the RV vertical cavity barrier.

Details – Small Voids RH If the void size is less than 75mm you can use non-combustible through fixings with washers or heads between 10mm and 15mm at 400mm centres instead of brackets with the RH ‘Open State’ cavity barriers

Details – Other Penetrations Lightning strips must be secured to the wall just above and below the cavity barrier, tightly install the cavity barrier around the strip making sure there are no gaps. If there are any type of pipe or cable penetrations, there must be additional specific protection such as a collar. Check with your designer what has been approved

Non-Combustible Fixings- Checked Project Spec

OSCI- Open State Cassette Inserts Fitting OSCIs should be done inside somewhere as dust-free as possible, they can be used with RH and RV cavity barriers 1. Clean and degrease the panel 2. Measure and cut to the required size using the method mentioned previously 3. Peel off the self-adhesive backing paper and align centrally to the correct position where the cavity barrier will be; the OSCI is 25mm larger 4. Apply to the panel asserting a good amount of pressure 5. Tape the top and bottom exposed mineral fibre edges to the panel SIDERISE recommend the OSCIs are also mechanically secured to the panel by: • Sitting in a return or rib of the panel • Using non-combustible insulation pins & non-return washers • Using SIDERISE brackets riveted to the panel side
