gap seals Explanation: Page 111 por lo general, los sistemas tradicionales de sello de pasadas y ductos son combustibles al fuego, por lo que en pocos minutos el fuego degradará el elemento de sello y la junta será un elemento de propagación de la llama hacia las diferentes unidades del sistema constructivo. es por ello que cuando el muro tiene una exigencia referente a protección contra incendios, se debe contar con un sello para este requerimiento, acorde con la resistencia al fuego exigida para este. There are a couple of diagrams on page 142 Comúnmente se utilizan dos sistemas para generar un sello resistente al fuego: sellos retardantes de fuego, que retardan la combustión de la llama, y sellos intumescentes en que el elemento de sello aumenta su volumen cuando la temperatura aumenta, evitando el paso de las llamas. en general los sellos que protegen contra el fuego se utilizan en ductos de ventilación, cañerías hidráulicas, bandejas eléctricas, entre otros (ver Figura 7.19). al momento de utilizar este tipo de sellos se debe tener en cuenta que: • se debe seleccionar el sello de acuerdo a la materialidad y porosidad de la superficie de los elementos, de esta manera se asegura una buena adherencia. además, se debe asegurar que el sello soporte las dilataciones térmicas o cualquier otro tipo de deformación o movimiento en la junta. • se debe verificar que el sello seleccionado provea la protección al fuego exigida. http://biblioteca.cchc.cl/datafiles/38491-2.pdf Page 6 Services (penetration seals, linear gap seals (fire stopping) fire resisting ducts, fire resisting dampers, service ducts and shafts) http://www.asfp.org.uk/webdocs/ASFP launch Fire Risk.pdf -------------------------------------------------- Note added at 45 mins (2019-10-04 23:17:58 GMT) -------------------------------------------------- Achieving effective fire protection throughout the full built environment requires detailed design to identify any areas which might facilitate the spread of fire or pose a significant risk to safe escape. While insulation which delivers fire protection will be specified as part of standard floor, wall and ceiling construction, there are more detailed areas such as compartment junctions and movement joints which need specialist treatment to ensure the building will perform under fire conditions. ROCKWOOL has developed a range of fire stopping products which prevent the passage of fire and smoke through junctions and joints. These A1 non-combustible solutions will not burn when exposed to fire, delivering the highest possible protection. Check out our range of products for linear gaps and seals below https://www.rockwool.co.uk/applications/fire-protection/fire... Penetration sealing is a fundamental requirement of Fire Safety in buildings, vital in maintaining compartmentation and preventing the spread of fire and smoke, the quality of these installations is crucial to the performance of the buildings specific Fire Strategy. Wraps/ Collars – Intumescent composition, designed to fit within a wall or floor and provide high volume expansion when exposed to fire forming a pressure seal to plastic pipes up to a diameter of 200mm. Collars work on the same principle but are face fixed to a wall or floor and the metal casing ensures expansion is contained to the inner area thus sealing the penetration as required. Linear Gap Seals – Elastomeric foam laminated with a graphite based intumescent compound on both sides, designed to perform as a 120 minute or 240 minute barrier in construction movement joints for long linear horizontal and vertical applications, it is water resistant and expands when exposed to heat, also used as a Fire Barrier in cable trunkings to allow for the installation of further cables. http://www.amber-fire.co.uk/services/fire-stopping/ -------------------------------------------------- Note added at 47 mins (2019-10-04 23:19:22 GMT) -------------------------------------------------- I think the proper term is 'linear gap seal'. -------------------------------------------------- Note added at 56 mins (2019-10-04 23:28:43 GMT) -------------------------------------------------- Here's the same product in Spanish and English http://ingservsolutions.cl/18-sellos-de-pasada Metacaulk® 1200 is a single component, highly elastomeric water based firestop mastic for general construction gaps and voids. https://www.metacaulk.com/product/metacaulk-1200-firestop-ca... -------------------------------------------------- Note added at 58 mins (2019-10-04 23:30:57 GMT) -------------------------------------------------- I think 'firestop sealant' is sufficient. |

Reference: Firestop sealants Reference information: https://en.m.wikipedia.org/wiki/Firestop Firestops prevent unprotected horizontal and vertical penetrations in a fire-resistance-rated wall or floor assembly from creating a route by which fire and smoke can spread that would otherwise have been fire resisting construction, e.g. where a pipe passes through a firewall. Fire stopping is also to seal around gaps between fire resisting constructions, e.g. the linear gap between a wall and the floor above, in order for construction to form a complete barrier to fire and smoke spread. https://firetec-contracts.co.uk/services/fire-stopping/ Intumescent Sealants Most commonly found in acrylic, silicone and graphite form, these sealants provide an intumescent seal by adhering to most types of surface which form a non-hardening flexible seal. Intumescent sealants can be used to provide fire resistance to walls, floors, fire rated doors frames & glazing systems. Linear gaps can be sealed in masonry walls to ensure that the passage of smoke, toxic gases and fire is suppressed for up to 2 hours. https://www.firemark.ie/services/ Linear gap seals installed after the construction of the superstructure are designed to maintain a fire separating function of compartments whilst accommodating a degree of movement within a building. The construction and products used for linear joints must withstand this movement and are generally comprise of a low-density stone wool batts, elastomeric foam or sealants which allows the expansion and contraction required. https://www.vijaysystems.com/fire-penetration-sealing-system... http://sbs-limited.com/penetration-seals.php |
