Firestop® Panels Essential Information

Firestop composite wall panels



See below for a list of essential information and frequently asked questions relating to our Firestop range.

For technical advice, please direct your query here.

What are Firestop panels?

Firestop panels are manufactured as part of Isoclad’s insulated fire resistant panel system.

How can Firestop fire resistant panels be used?

They can be used vertically or horizontally for both wall and ceiling applications.

Are Firestop panels quality assured?

The panels are manufactured to an ISO 9001 quality assurance system.

What core do Firestop fire resistant panels have?

Firestop panels have a mineral fibre* (European fire classification Class A1 rated) core. The non-combustibility of the mineral fibre core and steel facings give Firestop Panels a Class’0′ rating and according to the new European classifications for reaction to fire, a Class A2

What environments can you use Firestop panels?

Due to their superior fire ratings and non-combustibility, Firestop panels are especially suitable for high fire risk locations, such as bakeries, any area where cooking is prevalent or firewalls to comply with Building Regulations.

Lightweight fire rated non-combustible composite wall panels

The Firestop 10 (FStop10) is a lightweight fire resistant non-combustible wall panel designed for internal linings and partitions for general industrial applications and high-risk environments.

FStop10 has a density of 100kg and is suitable for low to medium height walls.

Strong and durable fire resistant non-combustible composite panels

The Firestop 12 (FStop12) is a stronger and more durable fire rated non-combustible panel primarily for use in internal and external applications where longer spans and greater loads and improved fire performance ratings need to be attained.

What joints can you have with Firestop panels?

Firestop panels can be installed using both the Intaloc and Secret Fix joint details.

Firestop fire resistant panels profiles

Flat: Laminated panel produces a much flatter surface than other manufacturing methods, but ‘optical’ flatness is not assured; some shadowing might be evident in certain lighting situations.

V-Rib: Pitch 200mm – 5 per panel

Castellation: Pitch 100mm

Micro-Rib: Pitch 30mm – 1 side only.

Maintenance of Firestop Composite Panels

Walls can be washed down with fresh water from a hose or bucket. A solution of freshwater and Tepol or non-aggressive detergent, which contains dilute ammonia, may be used to remove heavy deposits from walls, followed by a fresh water rinse.

Water temperature should not exceed 60°C with a maximum pressure of 1000lbs per square inch.

Stubborn oil or grease stains can be easily removed with white spirit on a soft cloth, followed by an immediate fresh water rinse.

Solvents, cleaners containing abrasives and cleaners in strong concentrations should not be used. Over-cleaning or scrubbing can do more harm than good.

To allow regular washing panels, it is important that both the design and maintenance of the panel system should prevent moisture collecting in crevices and joints. This is particularly important at the bottom of wall panels, where pollutants from cleaning solutions or from floor soil can cause corrosion problems. This can be achieved by a design which ensures that the edges are folded back and by sealing the edges with a natural curing silicone sealant.
