FAQs 

This is our Frequently Asked Questions (FAQs) page which we hope will help with some of the technical issues surrounding passive fire protection. If there is anything you would like to see featured here, please don’t hesitate to contact us using our Contact Form

Q: WHAT IS A FIRE DOOR?


A: Buildings are compartmentalised to prevent the spread of fire from one compartment to another. These areas are commonly linked by fire doors to allow access around the building. In case of a fire, a door has two important functions; when closed they form a barrier to stop the spread of fire, and when opened they provide a means of escape. When manufactured and installed correctly, a fire door will delay the spread of fire and smoke for varying degrees depending upon its location in a building and the fire hazards associated with that building.




Q: WHAT IS FIRESTOPPING?


A: Fire stopping prevents the spread of fire and smoke through fire-rated compartment walls and floors. This allows occupants to evacuate the building safely and slows down the spread of fire through a building for up to 4 hours. At LFS, we will carry out on-site surveys when necessary. These surveys are descriptive and informative; with photographs included where possible. We work in partnership with our customers, architects, main contractors and building inspectors to make sure we offer the most cost effective and appropriate fire stopping solutions for each project. All fire stopping works carried out are fully tested and clearly identifiable by our logging system of stickers, photos and log sheets. This provides assurance that all works undertaken comply with t11e specified fire strategy and Part B building regulations.




Q: WHAT FIRESTOPPING SOLUTIONS ARE AVAILABLE?


A: There are many firestopping solutions that LFS provide which on completion are fully tested and clearly identifiable by our logging system of stickers, photos and log sheets. Our list of firestopping solutions include: Fire rated ablative coated batt It acts as an air seal barrier to reinstate the fire resistance and acoustic performances of concrete floors, masonry walls and dry wall systems, following the creation of voids for the passage of services. Load bearing & non-load bearing fire-rated compounds LFS can design and customise the work required for different load-bearing floors. Fire rated movement barriers When there is movement of buildings these are beneficial so that the barrier is kept intact with the compartmentation of the building. lntumescent mastic seals An aqueous acrylic fire barrier mastic for internal use. Containing inert fillers and graphite. Maximum diameter 90mm combustible pipe seals or 60mm annuelar space around cables etc. Pipe collars A two part hinged, sturdy metal collar lined with intumescent material which expands in a fire. To be used when a wall has been penetrated by plastic flammable pipes used in soil, waste and drainage services. Pipe wraps This ruberoid strip has high flexibility and is most commonly used around all types of pipe insulation up to 50mm thick or combustible pipes with a diameter of between 20mm-160mm. They can also be used for conduits, cables and to close ventilated air spaces. lntumescent pillows These provide up to 4 hour fire protection to cables and metal services passing through compartment fire walls and floors. Insulated fire sleeves These are designed for use with plastic ducting that passes through walls. Openings in walls that allow ducts to pass through can also allow smoke and flames to pass through in the event of a fire. Fire-rated movement joints These are ideal for high movement, fast-fit curtain wall/slab edge and vertical cladding fire seals.




Q: WHY DOES A FIRE DOOR NEED TO BE FULLY CERTIFIED?


A: A professionally installed door that is fully certified for fire protection will delay the spread of fire and ultimately save lives.




Q: WHAT IS SECURED BY DESIGN?


A: Secured by Design (SBD) is the official UK Police flagship initiative supporting the principles of ‘designing out crime’. It focuses on crime prevention of homes and commercials premises and promotes the use of security standards for a wide range of applications and products. Our Secured by Design multipoint lock on our front entrance door increases safety and provides high security. Our assembly (frame + door + hardware) offers enhanced security to prevent opportunistic intruders.
