60 minute fire rating on Lath and Plaster walls in a heritage building Written by flammaltd on 14th November 2022. Posted in Uncategorised. Fitzwilliam Place, DublinHere you can see one part of the successful fire rating we achieved on this large project at Fitzwilliam place, a heritage building in the heart of Dublin. This project consisted of upgrading 785 square footage of lath and plaster walls to a 60 minute fire rating using the Envirograf EP/CP coating system. This coating system can be found on the Envirograf Ireland website here at Envirografireland.comPurpose This was applied using a high power sprayer to give it a clean, untextured finish. This also helps to give it a more durable and impenetrable barrier to protect against the spread of flames across a wall and ultimately on to the next wall, threatening to compromise the compartmentation of the building and cause rapid spread of fire through the structure of the building.ApplicationThis paint was applied with one coat at 100 microns with the EP/CP/P (primer), 2 coats at 125 microns with the EP/CP/IN (intumescent fire rated paint) and 1 coat at 100 microns for the HWAC (protective top coat). This 3 layered system gives a durable and protective 60 minute fire rating with the aim of giving all occupants of the building adequate time to safely and effectively evacuate the building. This is the first priority. The Second priority is to conserve the building of being totally destroyed before emergency services can put out the flames and protect the buildings surrounding it.ConsiderationsSince this is a listed building, like all other listed buildings, it needs listed building consent in order to have this work done to it. Thus, indicating its precious and valued nature of being a heritage building in Dublins strong standing historic Georgian infrastructure. For this reason it was very important that we approached this job with acute precision and be resolute in our standards in order to achieve the specified fire rating on the walls whilst ensuring not to interfere with the admired age worn essence of the building. EthosHeritage building conservation is a huge part of what we do here at Flamma Ltd. We believe it is a dishonour to our history and our ancestors to destroy or replace these heritage buildings that are so rich in antiquity. That is why here at Flamma Ltd provide the knowledge and the expertise to bring these sites up to modern fire safety standards so they can remain untouched and esteemed in their place whilst providing a safe working/living environment for its occupants.
