HORIZONTAL RAINSCREEN CLADDING BARRIER
DESCRIPTION :
CCL Rainscreen Cladding Barrier consists of rigid strips of non - combustible mineral wool that have all four edges faced with bright Class O reinforced foil . To one edge , a length of intumescent strip has been factory applied .
PURPOSE : CCL Rainscreen Cladding Barrier is designed to provide a horizontal barrier that will prevent the passage of smoke and fire whilst maintaining the requirement to provide a 25mm or 50mm cavity behind rainscreen cladding systems . This allows any penetrating water to drain vertically and a free flow of air around the building envelope .
BENEFITS :
Fabricated to suit specific cavity size Integral intumescent edge strip Simple fixing system 60 - 120 minutes fire resistance Maintenance free

Dimensions
Fixing :
CCL Rainscreen Cladding Barrier is manufactured to suit the specific cavity width , fire rating and residual gap required : HRSB 60 / 25 60 min fire 25mm gap HRSB 60 / 50 60 min fire 50mm gap HRSB 120 / 25 120 min fire 25mm gap HRSB 100 / 50 100 min fire 50mm gap
Rainscreen Cladding Barrier is secured to the inner structural wall utilising one of the unique Rainscreen Barrier Bracket systems . For smaller cavities , these are supplied with a flat shaft to suit the specific barrier width supplied . Wider cavities utilise our unique self - retaining bracket . Care should be taken to ensure the insulation fits tightly into the bracket and is held firmly against the inner structural wall . Two brackets should be used per length of barrier sited approx . 250mm from each edge . The brackets are secured to the inner wall using steel anchors or screws before the insulation is " push fitted " into place .
Vertical Barriers :
For vertical barriers in rainscreen systems it should be possible to fully fill the void with CCL Firestop Slab . - CCL Firestop 60 provides 60 minutes fire resistance . - CCL Firestop 120 provides 120 minutes fire resistance .
Standards & Performance :
The mineral wool core of a CCL Rainscreen Cladding Barrier achieves a fire classification of Euroclass A1 as defined in BS EN 13501 - 1 . The product has been independently tested adopting procedures and criteria of EN1363 - 1 - 1999 and principles of EOTA - TR31 . The system was tested between two concrete lintels as outlined in Technical Guidance Document TGD - 19 . Guidance should be sought to ensure the fire performance of the building envelope is comparable to the selected cavity barrier .
Adjacent lengths of barrier should be tightly butted and the top of the joint sealed with foil tape .
