We’ve set up the latest in Cad-Minimize technologies in order that this in-residence Procedure creates by far the most accurately Lower, finely concluded indicators doable.

Integrity: Enough time through which the duct is subjected to fire right up until a loss of integrity occurs, like deformation, melting, or collapse.

All through this kind of fire, the temperature in the duct may be around 800°C and outside of. This enormous temperature elevate involves substantial-stop, specialised insulation options to shield the men and women inside these properties. ROCKWOOL fire rated duct items may help minimise the danger this poses, and secure life. Appropriate means ROCKWOOL products abilities

Reduction in cross-portion: The interior dimensions (width and top for rectangular ducts, diameter for circular ducts) from the smoke extracting ductwork shall not minimize by in excess of 10% in the take a look at.

The acoustic performances and the area temperature thermal insulation of Promat ductworks could be even improved by using more levels of mineral wool or plasterboards.

This substantial-functionality FireMaster technique is crucial to reduce warmth transfer across a wall or roof subjected to fire, blocking ignition of combustible products about the non-fire exposed aspect.

It is possible to electronic mail the positioning operator to let them know you have been blocked. Be sure to consist of That which you were doing when this webpage arrived up as well as Cloudflare Ray ID discovered at the bottom of the web site.

Promat has created self-supporting devices without a steel liner, one example is PROMATECT®-Advert, PROMATECT®-L500 and MASTERBOARD®, which may match the leakage and air stream performance of steel ducts the two for air ducts and smoke extraction ducts.

The fire resistance limit of ducts refers to the length from in the event the duct is exposed to fire right up until there is a loss of Bodily integrity, thermal insulation capacity, or structural collapse.

A flexible wrap developed for reducing the distribute of flame and smoke emission inside of a fire of plastic pipes or any framework carrying plastic coated cables.

Ventilation duct insulation aids retain the functioning temperature of HVAC methods and prevents Strength reduction. Determine extra with ROCKWOOL solutions.

After you have chosen your products and solutions, click on the 'Basket' button on the highest menu to evaluation your goods. On completion, your payment is processed via Stripe. You will be required to maintain a sound credit history or debit card.

ROCKWOOL Additional hints merchandise can provide sizeable fire security for steel building constructions, such as metal beams. Safeguard your building.

Flamebar BW18 fire resisting ductwork procedure is developed in sections and assembled on site utilising examined fireproof gaskets/sealants.
