If you want to offer excellent passive fire protection for rain screens and other types of
cladding, then Fire Cavity Barriers is the best option. The fireproof sponge of mineral
wool provides a range of advantages:
There are four fitting brackets for horizontal application and three brackets for vertical
and to fit around metalwork cut with a sharp knife. The cover is made from a robust and
tumescent-coated material, completely water-resistant.
The building elements must be fire resistant and installed at any joint in the fire
protection element. A passive fire protection element must seal and close an
imperfection of fit. The building elements into which it is installed must provide the same
degree of insulation and resistance to the passage of flame and smoke.
For flame, hot gasses, and smoke to propagate from one building compartment to
another, a concealed space in the external wall can act as a chimney and provide an
accessible route. The air is drawn in with unsealed cavities, and smoke is vented out,
which enables the fire spread to accelerate through the facade. The flames within a hole
extending between 5 to 10 times higher than the flame, not within the cavity. The rapid
spread of fire from one compartment to another is prevented by carefully selected
vertical and horizontal cavity barriers.
Siderise R-H which is ‘Open State’ horizontal and also the Siderise R-V which is the vertical cavity
barrier vary represent the default selection for the market leading, superior Rainscreen Cavity
Barrier
- permits continuous ventilation and drain behind the external envelope
- merchandise tested in isolation and in large-scale system tests
- Reactive intumescent has fast seal closure properties
- Horizontal barriers will incorporate up to 50mm continuous louvered air area
- Vertical barriers accommodate facing usefulness movement
Siderise RH Horizontal cavity barriers:
Siderise has developed the 2 of the very beautiful ‘Open State’ (open void) horizontal solutions: R-H-
2-5 (G/S) for the air gaps of up to 25mm and also including the R-H-5-0 (G/S) also for the air gaps of
up to 50mm. Siderise RH Horizontal cavity barriers is also used with variety of facing sorts (for
example: quadrangle, sinusoidal, ribbed and seamed), but the utmost gap at any purpose should not
exceed the explicit ‘air gap’ – e.g. 25mm for RH25 and 50mm for RH50. For panels outside of those
limits please contact Siderise. the merchandise vary is compliant to current market necessities and
has been tested to ASFP Guidance: ‘Open State’ Cavity Barrier employed in External Envelope or
material of Buildings, utilising principles of linear unit 1363-1. ASFP Technical steerage Document –
TGD nineteen (July 2014 revised Nov 2017) refers.
Siderise RV vertical cavity barriers for rainscreen facing square measure accustomed full fill the void
between any of the external envelope and also the internal structure. By totally waterproofing the
void they assist louvered façades to operate by maintaining air-pressurisation compartmentation.
considerably, their very distinctive stonewool lamella core construction which permits the vertical
barriers to accommodate the usefulness of the movement ordinarily related to the rainscreen
façades. Intersections between horizontal and vertical cavity barriers square measure merely
abutted.
These cavity barriers square measure put in within the void shaped between the rainscreen façade
and also the inner structural wall mistreatment the acceptable screw fixings or Siderise support
brackets (see Tables 3-5).
To prevent hearth flanking to the rear of the hearth stop, any thermal insulation fitted to the outer
face of the structural wall should be fully cut away to accommodate the thickness of this product.
The very beautiful of the R-H-2-5 (G/S) horizontal cavity barrier is fitted with the very plain mineral
fibre edge also against any of the structural wall. A 25mm ±3mm (dimension could be very easily
alter with a very specific style criteria) to clear the air gap ought to be left between the front fringe
of the cavity barrier and also to the rear surface of the rainscreen façade.
The adjacent lengths of the horizontal cavity barrier ought to be very tightly abutted to forestall the
gaps. the highest surface of the joint ought to be sealed with Siderise aluminum Jointing Tape.
These cavity barriers square measure put in within the void shaped between the rainscreen façade
and also the inner structural wall mistreatment the acceptable screw fixings or Siderise support
brackets (see Table 4).
To prevent hearth flanking to the rear of the hearth stop, any thermal insulation fitted to the outer
face of the structural wall should be fully cut away to accommodate the thickness of this product.
Siderise R-H-5-0 (G/S) very beautiful horizontal cavity barrier is fitted with a very plain mineral fibre
edge against the actual structural wall. A 50mm ±5mm (dimension might alter with specific style
criteria) clear air gap ought to be left between the front fringe of the cavity barrier and therefore the
rear surface of the rainscreen façade.
The adjacent lengths of the very beautiful horizontal cavity barrier ought to be very tightly abutted
to forestall the gaps. the highest surface of the joint ought to be sealed with Siderise atomic number
13 Jointing Tape.
Support brackets
A range of very beautiful Siderise support brackets for horizontal cavity barriers area unit obtainable
for void widths of up to the 425mm for 25mm air gaps or up to the 300mm for the 50mm air gaps
(see Table 4). For voids of 0-75mm fixing screws area unit needed, see Table four, note these don't
seem to be equipped by Siderise and will be non-combustible and appropriate for substrate.
Lengths of the barrier area unit secured with these dedicated ’split’ fixing brackets, that area unit impaled through the merchandise at middle thickness.
The brackets area unit trained on website and secured to the inner structural wall mistreatment non-combustible steel anchors or screws. These fixings don't seem to be equipped by Siderise.
Please note:
For cut lengths a minimum of two brackets per length should be used. once mistreatment Siderise
support brackets, pre-fitting the brackets to the merchandise is suggested before fixing to the wall.
For cut lengths
Screws refers to the fixing with the washer and a 15mm (max) of the head diameter. they must be
non-combustible and appropriate for substrate. These fixings don't seem to be equipped by Siderise.
To facilitate bracket penetration, alittle horizontal cut ought to be created within the face
intumescent strip coinciding with the bracket’s exit purpose.
The projecting split ends ought to be cut to 10-20mm and counterfolded to retain the merchandise.
Siderise recreational vehicle for the vertical cavity barriers for a rainscreen facing applications and
contains a non-combustible stonewool lamella core, with strengthened foil faces, giving AN overall
reaction to fireside performance to monetary unit category ‘A1’.
The exposed forefront is additionally sealed with foil. while the bottom material is water repellent
and non hydroscopic, this preponderantly fenced in arrangement affords another degree of weather
protection to the core material.
Siderise recreational of the very beautiful vehicle vertical cavity barriers for the area unit which also
accustomed to full fill the void between the external envelope and also the internal structure. The
forefront compresses directly against the external envelope, so no intumescent strip is needed.
The construction offers a superb resistance to the passage of each smoke and hearth. in addition, by
absolutely waterproofing the void, they assist vented façades to operate by maintaining air-
pressurisation compartmentation.
Importantly, the Siderise recreational vehicle vertical cavity barriers distinctive stonewool lamella
core construction allows the vertical barriers to accommodate the serviceableness movement
usually related to rainscreen façades.
Insulation
Siderise have tested horizontal cavity barriers with 50mm air gap to the ASFP TGD19 technique.
throughout the hearth tests, the seals achieved full effective closure in underneath a pair of.5
minutes. Seal temperatures remained below one80ºC throughout this activation amount and
maintained the EI necessities as careful in Tables 1 for up to EI60.
