Fire Stop Blocks
Verified by manufacturer 3 months ago
Fire and smoke stop blocks for apertures in buildings, especially the flutes of trapezoidal formwork.
Application
- Composite flooring profiles.
- Roofing and cladding.
- Designed for use in metal decking, typically at the head of a wall.
- Can be used at the head of a partition, if the head track is fastened to the metal deck, but should be approved by a Fire Engineer or Building Control.
Description
AIM Fire Stop Blocks are made from high density Rockwool stone wool. Incorporated into the building during construction, they are used to seal apertures and are permanently held in place by compression. They can also be used within metal cladding as a firebreak and to protect the top flange of steel beams.
AIM Fire Stop Blocks are predominantly supplied as trapezoidal sections. Square cut, rectangular or round sections are also available.
Features and benefits:
- Simple to install – no tools required.
- One and two hour fire rating.
- Ablative/ pre-painted option available.
- Manufactured to any profile.
- Up to 1200 mm long.
- Maintains fire compartment lines.
- A barrier to the movement of smoke.
- Contributes to acoustic performance of the wall or partition.
- Many profiles CNC Cut for ultimate accuracy, especially for profiles with rounded shoulders.
- Compression fit so no mastics or sealants required.
Fire performance to EN 1366-4:
120 minutes (maximum), assessed by Warrington Fire Research Centre.
Sound reduction:
Reduces flanking transmission by 9 dB.
Environmental:
Ozone depletion potential of zero, no CFCs or HCFCs used in manufacture.

Specification data - Mineral wool insulation
Standard | To EN 1366-4 and ISO 10140-2. |
Form | Metal deck profile reference.Guidance for specification option: Insert details of the manufacturer and reference for the metal deck. Typically a metal deck reference will be along the lines of: Wards MD60, Corus CF70, SMD TR60, Rigidal 20/100/1000 and similar. Consult manufacturer for details. Bespoke.Guidance for specification option: Insert details; dimensions required:
Manufacturer guidanceTo be specified in conjunction with length, required fire performance and approximate quantity. |
Density | High density stone wool.Guidance for specification option: Consult manufacturer for details. |
Thickness (minimum) | Guidance for specification option: Profiles from 100–1200 mm deep. Insert requirements. |
Width (nominal) | To suit the profile. |
Fire performance | Euroclass A1. |
Sound insulation rating | 100 mm long block: 18 dB Rw. |
Length | 100–1200 mm. Guidance for specification option: Depending on the fire performance required. Insert requirements. For bespoke orders, specify whether a special special length of block is required i.e. to match the width of a wall or partition. |
Durability | AIM fire barriers are chemically inert, will not sustain vermin and do not encourage the growth of rot, fungi, moulds or bacteria. Guidance for specification option: They do not degrade under the usual conditions found in buildings and will perform effectively for the life of the building. |
Compatibility | Compatible with all normal building materials. |
Environmental | Global warming potential = zero. Guidance for specification option: AIM fire barrier products are manufactured from stone wool insulation which is universally recognised as being a sustainable and environmentally friendly material. |
Fire rating | To BS EN 1366-4, EI 120/60 minutes (standard 100 mm) to EI 120/120 (standard 125 mm or ablative 60 mm). Guidance for specification option: Integrity/ insulation. Tested conducted in a composite metal deck with masonry below, metal deck profiles C19, CF80 and CF225. Note that ablative 60 mm performance applies to C19 and CF80 only, and is subject to being sealed in situ using AIM Acrylic Intumescent Mastic (specified separately). |
