Things you should know about this product!
  • This product is sold by the pack
  • This product is available in the following thickness: 90mm

Description

AIM Open State Cavity Barriers (OSCBs) are made from high-density Rockwool stone wool and feature an intumescent strip, with colour coding for easy identification. These barriers allow necessary ventilation within wall constructions and, in the event of a fire, the intumescent strip activates and expands to fully close the cavity.

AIM OSCBs are designed and tested for use in ventilated rainscreen façades and timber frame constructions, enabling free airflow and drainage. They provide an effective fire barrier for ventilated voids up to 425mm wide. Tested to TGD 19 and the general principles of BS EN 1363-1, they offer a fire rating of up to 120 minutes for both insulation and integrity in ventilated air spaces within the cavity.

The AIM OSCB range is available with either a 25mm or 44mm air gap. The range also includes options for 60 or 120-minute ratings for both integrity and insulation.

Where to use

Open State Cavities:

Fire Protection:

AIM Open State Cavity Barrier is specifically designed to prevent the spread of fire and smoke through open state cavities. It expands in response to heat, sealing gaps and maintaining fire integrity.

Maintains Ventilation:

Unlike traditional cavity barriers, it allows for airflow and ventilation in normal conditions, which is crucial for the prevention of condensation and moisture build-up within the cavity.

Compliance with Building Regulations:

The barrier meets stringent fire safety standards and building regulations, ensuring that it provides the necessary fire protection required in open state cavities.

Thermal Efficiency:

By preventing the spread of fire, the cavity barrier also helps maintain the thermal integrity of the building, contributing to overall energy efficiency.

Ease of Installation:

AIM Open State Cavity Barrier is designed for straightforward installation within cavities. Its flexibility and ease of handling make it suitable for various construction settings and types of cavity walls.

Durability:

The materials used are durable and designed to withstand the conditions within a cavity wall, ensuring long-term performance and reliability.

Minimal Maintenance:

Once installed, the barrier requires minimal maintenance, providing long-term fire protection without the need for frequent inspections or replacements.

Adaptability:

The barrier can be adapted to fit different sizes and types of open state cavities, making it a versatile solution for various construction designs and requirements.
