We’ve been designingand manufacturinghigh performancefire dampers foralmost 40 years.Fire and smoke protection measures areessential, life-saving precautions in abuilding. What’s more, they protect theproperty from the devastating consequencesof the fire itself, and the damaging effectsof hot and cold smoke. So it’s essential toget the product selection right, every time.Lorient has an international reputation fordesigning and manufacturing a wide range ofinnovative sealing solutions for the containmentof fire, smoke, sound and energy.With almost 40 years of accumulatedknowledge we pride ourselves on offeringproducts that are designed to save lives,preserve property and enhance quality of life.We recognise our responsibility to createwell-designed products that will perform;products which are durable and reliable, andwhich genuinely improve the buildings theyprotect. By doing so, we can play our part inimproving life safety, amenity and reducingbuilding damage and loss.01
IN T U ME S C E N TF IRE DA MP E RSManufactured for over 25 years, the originalLorient LVH44 Intumescent Fire Damper is thetrusted, versatile fire containment solution.Design needsSub-dividing buildings into smaller fireresisting compartments is a recognisedmethod to limit the spread of fire.Building a fire resistant wall or floor toconstruct an enclosed compartmentis relatively simple. However, buildingdesign becomes much more complexwhen the compartments need to belinked for everyday use.Ventilation through ductingDesigners recognise the need forbuildings to be well ventilated for thehealth and comfort of occupants.Frequent changes of air are requiredto flush out airborne infections,and warm and cool air needs to becirculated to maintain a comfortabletemperature.Experience has shown that ductworkcan, in the event of fire, provide aconduit for fire, as well as the hotsmoke and toxic gases it produces.02LVH44 LVH44C Intumescent Fire DampersAs HVAC systems frequently penetratefire compartment boundaries, it isthese points that must be treated inan approved manner to preserve theintegrity of the fire compartment.The Lorient solution is to install aLVH44 intumescent fire damperinto the duct at the point where itpenetrates the fire resistantconstruction.Under normal circumstances theyallow air to pass freely but a suddenincrease in temperature, resultingfrom the presence of hot flames orgases, will cause the slats to expandto many times their original thicknessfusing together to form a stable fireresistant barrier, which restricts fireand limits the spread of hot smokeand toxic gases.This will effectively limit the spreadof fire and restrict the passage ofhot smoke and toxic gases.What are intumescentfire dampers and how dothey work?The Lorient LVH44 intumescent firedamper comprises a rigid galvanisedsteel framework that supports a seriesof evenly spaced reinforced parallelslats that contain an intumescentmaterial.www.lorient.com.auImage: Showing Lorient Damper activatedand Lorient Damper normal
AUS T R AL I ANM ADELorient LVH44 Intumescent Fire Dampers are arecognised and well respected brand. Lorient isproud to continue to offer the LVH44 and LVH44CIntumescent Fire Dampers to the Australian andNew Zealand markets.Australian madeReliabilityProduct identificationManufactured in Sydney to the highestquality, Lorient intumescent firedampers are designed and approvedfor use in a host of differentapplications, providing a range ofproven versatile solutions all inaccordance with the latest Australianstandards – see our system selectorfor full details.Lorient intumescent fire dampersoffer a rugged, reliable solid statedesign that unlike conventionalmechanical fire dampers do notcontain any moving parts.All Lorient intumescent fire dampersare supplied with Lorient branded foilto allow for easy identification.Their symmetrical construction allowsfor bi-directional airflow and they aresimply activated by a rise intemperature. The LVH44 fire damperproduces a tightly sealed, highlyinsulative intumescent mass thatprovides a barrier to fire, and alsorestricts the spread of hot smokeand radiated heat.LVH44 Insulating Fire Rated Air Transfer Grilles.LVH44 Fire Rated AirTransfer GrillesSystem featuresincludeLorient LVH44 fire rated air transfergrilles provide air transfer betweencompartments without the need forconnecting sheet metal ductwork.They are able to provide bothinsulating and non-insulatingperformance depending uponconstruction requirements.Lorient intumescent fire dampersoffer a rugged, reliable solid statedesign, that unlike conventionalmechanical fire dampers do notcontain any moving parts.Lorient LVH44 fire rated air transfergrilles are tested and approved toSection 10 of AS1530.4 2014 and offerdesigners, specifiers and mechanicalconsultants a simple and compliant airtransfer solution.LVH44 LVH44C Intumescent Fire DampersTested and approved in accordancewith the very latest standards theyoffer designers, specifiers andmechanical contractors a simpleand compliant fire damper solution.www.lorient.com.au03

S TANDARD S RE G UL AT ORYRE Q UIRE ME N T SIn Australia, building construction is regulated under aframework of provisions detailed within the NationalConstruction Code and associated Building Code of Australia.These codes set out a uniform set of technical provisions thatallow for the design and construction of buildings; they alsomake reference to a number of Australian and Internationalstandards to ensure that materials, systems, products andservices provide a consistent and quantifiable performancelevel to ensure the safety of occupants in the event of a fire.NCC BCA 2016Section C3.15 (b)AS1682.1 2015: FireDampers: SpecificationThis section requires that ventilationand air-conditioning ducts orassociated equipment are installedin accordance with AS1668.1 2015.This standard specifies requirementsfor the materials, design, manufacture,performance, and labelling of firedampers. In all cases it requires thatfire dampers are tested and approvedin accordance with the fire testmethod detailed in AS1530.4 2014.AS1668.1 2015: The Use ofVentilation & Air Conditioningin Buildings - Part 1: Fire &Smoke Control in BuildingsThis recently revised standard sets outthe minimum requirements for thedesign, construction, installation andcommissioning of mechanical smokecontrol systems in buildings andrequires that fire dampers – bothmechanical and intumescent typesare manufactured and installed inaccordance with AS1682.1 2015 andAS1682.2 2015. This 2015 versionstandard now mandates new insulationperformance criteria for fire dampersthat are not installed in shaft wallsor connected to 2m of ductwork.It requires such fire dampers tomatch the FRL (including insulation)of the walls that they penetrate.10LVH44 LVH44C Intumescent Fire DampersAS1682.2 2015: FireDampers: InstallationThis standard specifies therequirements for the selection,installation and commissioning of firedampers complying with AS1682.1.AS1530.4 2014: FireResistance Tests on Elementsof ConstructionThis standard provides methods fordetermining the fire resistance ofvarious elements of constructionwhen subjected to standardised rangeof fire exposure conditions.
