Intumescent Fire Seals

Firestop intumescent door seals are designed to close the gap between the fire door and frame in the event of a fire, thereby preventing the spread of smoke and hot gasses.

Once installed our seals can lay dormant for many years, only activating when exposed to the rising temperatures and pressures in a fire situation.

Finger Protection

Every year in the UK, over 30,000 children suffer injury by trapping their fingers in doors.

The vast majority occur in the large gap in front of the hinge, as the door closes. The rear of the hinge also presents a potential hazard to careless small hands. Both sides are capable of exerting thousands of pounds of pressure per square inch, on an innocent child’s fingers.

The devices we offer fit most doors and are very easy to install. They are designed and tested to be durable and eliminate the possibility of finger trapping accidents.

Air Transfer Grilles

A comprehensive range of 30 and 60 minute fire rated air transfer grilles designed for use in fire resisting doorsets and compartment walls.

Pipe Collars and Wraps

Firestop Pipe Collars are primarily designed for retro-fit to plastic piping or trunking where it passes through fire resistant structures such as walls or floors.

In the event of a fire, the collars’ intumescent core rapidly expands to crush the pipe or trunking, which seals off the area and maintains the fire integrity of the structural element.

Our Intumescent Pipe Wraps are designed for installation around plastic piping or trunking passing through fire resistant structures such as walls and doors.

Fire Rated Sealants

Firestop intumescent acoustic acrylic sealant is a halogen free, polymer emulsion based sealant which is ideal for sealing joints in and around internal partitions, between fire doors and fire rated walls and lap joints in fire rated cladding.

In the event of a fire it forms a char coat that restricts the passage of smoke and fire. It is easily applied and dries to form a flexible and smooth surfaced material that can be painted over.
