About Dufaylite Developments Ltd

FIRE PROTECTION PRODUCTS
Dufaylite Developments Ltd manufacture a complete range of fire protection systems, specifically designed to give building contractors flexibility and reliable protection from 30 minutes to 4 hours in a wide variety of applications.
This section is intended to give professionals an overview of the range; full technical specifications and installation instructions are available upon request.
Included in the Dufaylite range of fire protection products are fire dampers & grilles, firesleeves & pipe wraps, strips and sealants, fire batts, bags and mortar to provide an effective passive fire solution for all parts of the building envelope.

Fireblock
The principle of Fireblock was developed by the Fire Research Station, and is the original intumescent honeycomb damper, renowned for its reliability and air movement efficiency.
Designed to provide 1 hour fire resistance in accordance with BS476 Part 20 (1987) and ISO 834, Fireblock is available in square and circular formats to suit interior applications and can be made to fit irregular angles within the building envelope. Joined together, Fireblock forms an effective fire compartmentation in roof space, walls and floors, allowing the free movement of air in non-fire situations.


Dufaylite Developments Ltd ImageFireblock FD30 & FD60
Designed specifically for flush mounting into 1/2 hour and 1 hour internal fire doors and partitions, Fireblock FD30 and FD60 provide effective ventilation in non-fire situations.
Both products have been tested in accordance with BS476 Part 20 (1987) with all the inherent benefits of the standard Fireblock construction. Non-vision blocks are also available.


Fireblock Ultra
Fully certified in accordance with BS476 Part 20, Fireblock Ultra dampers are designed to provide up to 83% free area and up to 4 hour fire rating for optimum performance. Manufactured from slats of quick activating moisture-resistant intumescent material secured in a galvanised steel frame, Fireblock Ultra is a robust damper ideal for high air movement. Suitable for aggressive environments and resistant to moisture, Fireblock Ultra is suitable for both external and internal situations with fast closure in a fire situation.

Fireblock Ultra Hi Air
For high air movement ducting, Fireblock Ultra Hi Air dampers have been purpose designed to provide a super efficient performance. The damper's framework is sited on the outside of the duct to eliminate all 'solid' elements of the damper from within the duct interior. Fireblock Ultra Hi Air is manufactured from the samequick activating material as Fireblock Ultra with all the inherent benefits.
