Rockwool launches Fire Stopping Technical Manual

Rockwool has produced a Fire Stopping Technical Manual to help contractors and installers find an effective sealing system for penetrations and substrates in walls, floors and roofs.

The growing use of different kinds of services passing through the building fabric makes it essential that the sealing methods should consider the risk of fire spreading through the services, along their surface or through any cavities within the surrounding construction.

As a minimum requirement, each service or void must be fire-stopped to match the fire performance of the wall, floor or roof through which it passes.

When considering the variable characteristics of the voids and services, selection of the most appropriate fire stopping system can be a complex process for the installer, but one that legally, morally and professionally has to be successfully performed.

The new Fire Stopping Manual, available in PDF format from Rockwool's website, has look-up tables which match different types of openings with the appropriate fire stopping system solution.

Its installation drawings give the precise details of how to install those products to achieve the fire required rating.

It includes all relevant product data sheets and additional test reports, such as air-tightness and acoustic performance of the Rockwool Ablative Coated Batt.

Rockwool's fire stopping solutions have been fire tested and assessed for up to four hours and cover penetrations through plasterboard or blockwork, for wall or floor applications, where pipes, cables or ducts are passing through openings of up to 2.4x2.88m.

Rockwool Ablative Coated Batt is the only fire-stopping batt that is manufactured using a fully automated process, which includes the spray application of the ablative coating to Rockwool stone wool slab.

This ensures uniform coverage and thickness of the ablative coating which is not always achieved in manually applied processes.

Rockwool has submitted fire test reports and assessments to LPCB, who has given third party approval for ablative coated batt and acoustic intumescent sealant to be used in defined penetration sealing situations.

This makes Rockwool one of the few companies with a fire stopping system that has third party approval.

The Rockwool Fire Stopping range is further complimented with other components including: Acoustic Intumescent Sealant, Insulated Fire Sleeves, Fire, Conlit Bandage and FireDuct Systems.

Steve Connelly, fire protection specialist from Rockwool said: "Having an up to date Technical Manual that incorporates fully tested fire stopping solutions not only makes life easier for all parties in the construction process, but also ensures peace of mind that solutions specified and installed in accordance with the manual will help ensure compliance with both Part B building regulations and the Regulatory Reform (Fire Safety) Order".
