Acoustic Smoke and Fire Seals

When fire breaks out in a building the threat is twofold. Firstly, there is the fire itself and the hot smoke generated in the immediate vicinity. Secondly, there is cold smoke which will spread rapidly through the building, threatening people and property some distance from the fire. The Building Regulations take both these threats into account, and supporting documents give criteria for how they can be managed.

Acoustic, Smoke & Fire Containment Systems Product Overview

Fire and smoke protection measures are essential, lifesaving precautions in a building. What’s more, they protect the property from the devastating consequences of the fire itself, and the damaging effects of hot and cold smoke. So it’s essential to get the product selection right, every time and this overview provides a summary of the entire Lorient range of acoustic, smoke and fire containment systems.

Acoustic, smoke and fire door seals - datasheets

Gaps around the four sides of a fire door leaf are essential its the only way the door can open + close. But these gaps create a point of weakness, where fire can take hold + destroy the door, + lethal smoke can pass through. Lorients intumescent seals protect those gaps. Most of the door seals shown here are multi-functional + provide protection against fire, smoke, sound leakage + heat loss. These seals are used in the top + vertical sides of door leaves, or in the frame. The bottom of the door should be sealed with a threshold seal from our architectural seals range.

BBA approvals provide independent assurance for the designer, specifier and end-user as to the “fitness-for-purpose” of building products. To achieve this accreditation, Lorient acoustic, smoke and fire seals were subjected to a comprehensive appraisal, conducted over a two-year period. Rigorous audits of the manufacturer’s procedures are regularly conducted and it is a condition of BBA approval that a complete re-appraisal of the relevant products is carried out at, maximum, 3-year intervals. Lorient seals have successfully completed this review process on each occasion since the original approval was awarded. Lorient remains the only manufacturer of combined acoustic, smoke and fire seals to hold BBA approval on its mainstream range of seals.

Fire Door Inspection Services

Lorient offers a professional and experienced fire door inspection service. Certificated to carry out detailed inspections of your buildings fire doors.

Fire Resistant Glazing Systems

Glazed panels are often required in fire resistant walls and doors to allow vision and natural light. In door assemblies, they allow people to see others approaching from the opposite direction; they also allow fire and smoke to be seen without opening the door - an important safety benefit. However, gaps, joints and interfaces between dissimilar materials invariably form points of weakness and provision needs to be made to seal these effectively. The solution is to fit fire resistant glass secured using one of Lorient's fire resistant glazing systems; which holds the glass firmly in place during normal use, but in the event of fire the intumescent material expands, securing and insulating the glass and protecting the surrounding timber.

Lorient Air Transfer Grille Datasheets

Air movement in a building is important. Grilles are fitted into walls and some doors; and ductwork to keep fresh air circulating. But wherever air moves, fire and smoke can travel too. In a fire, our intumescent air transfer grilles expand to form a solid block that stops fire spreading. Wherever ventilation is needed through a fire-resisting wall or where ductwork runs through that wall, an intumescent air transfer grille should be fitted at that point to maintain fire compartmentation. Smoke protection is also vital. We offer a range of intumescent grilles and dampers with an added smoke control shutter: our Talkback system.

Lorient drop seal datasheets

A range of drop seals that fit to the bottom of a door and drop down automatically when the door closes to form a firm seal. Options include face-fixed installation, and semi or fully mortising into door leaves, for both medium and heavy duty applications.

Lorient Fire Resistant Glazing Datasheets

Glazing in fire doors + screens is an important safety measure. But adding glazing to a door creates a point of weakness. Where the timber + glass meet, fire can take hold. Also, without support, the glass can quickly slump + fail in the extreme heat of a fire. Lorients intumescent glazing systems hold the glass firmly in place. In a fire, the glazing system prevents the glass from slumping. It also stops heat transferring to the timber, so fire cannot take hold around the edges of the glazing aperture. Our systems include a glazing channel or strip, beading, + in some cases an intumescent liner.

Lorient Free Air Characteristics

Free Area is the area within an aperture unobstructed by the components of a damper or air transfer grille product when in the normal or open position through which air is free to flow.
