For Builders

Although the required structural fire protection for builders is documented in either the architectural or engineering documentation, the requirements are not always outlined clearly. It is important to understand how intumescent coatings behave and the components involved to ensure the fire protection is carried out accurately.

Structural fire protection is an essential aspect of building safety, and ensuring that the required fire protection is accurately carried out is critical to protecting building occupants in the event of a fire. However, understanding the requirements for structural fire protection can be complex, as the necessary information is not always clearly outlined in the architectural or engineering documentation. This is where Permax can provide valuable assistance.

At Permax, we are dedicated to helping builders and other construction professionals throughout the timeline of their projects. We understand that addressing fire rating issues in advance can result in significant time and cost savings on a project, which is why we offer our expertise during the early contractor involvement phase. Our team can help to ensure that all prescribed steel section sizes can achieve their required fire resistance levels (FRLs) and optimize steel section size to save on intumescent fire protection costs.

Here is how we can help you throughout the timeline of your project:

Early Contractor Involvement:

  • For design and construct contracts or where early contractor involvement is sought, addressing the fire rating issues in advance can result in time and cost savings on the project
  • Ensure that all the prescribed steel section sizes can achieve their required FRLs
  • Optimise the steel section size to save on the intumescent fire protection costs.

Tender Phase:

  • Permax can assist with providing details of approved applicators who can provide costs for structural fire protection on your project
  • During the tender phase, it is important to ensure applicators have been provided with the intumescent specification so that they can include the required components.

Permax has extensive experience in providing structural fire protection solutions for builders, and we are committed to providing comprehensive support throughout the project timeline. We understand the behavior of intumescent coatings and the components involved, which allows us to ensure that the fire protection is carried out accurately and effectively. Our goal is to help ensure that your project meets all necessary safety standards and regulations and provides reliable protection for building occupants.

In conclusion, structural fire protection is a critical aspect of building safety, and Permax can help builders and other construction professionals to navigate the complexities of fire protection requirements. By providing expert support during the early contractor involvement and tender phases, we can help ensure that the necessary fire protection components are included in the project’s budget and that the structural fire protection is accurately carried out. Our team of experts is committed to providing comprehensive support throughout the project timeline to ensure that your project meets all necessary safety standards and regulations.

Structural Fire Protection For Builders is an essential part of the safety process. Permax can help you with that.

FREQUENTLY ASKED QUESTIONS

Can any primer be applied before Nullifire SC902?

No, only approved primers may be applied prior to overcoating with Nullifire SC902. Please check the approved primers list for compatibility or alternatively contact Permax.

How can I get a price for intumescent fire protection?

There are approved applicators of the Nullifire intumescent system Australia wide who would be happy to assist with a quote. Please contact the Permax team for further information.

Can any top coat be applied over Nullifire SC902?

No, only approved top coats may be applied over Nullifire SC902 Intumescent. Please contact Permax for list of approved top seals.

Can anyone apply the product?

No, you need to be an approved applicator with proper training with the intumescent and equipment in order to apply the product. Please contact the Permax team for further information.

What does the products cost per m2?

The thickness of an intumescent coating is calculated based on the FRL, steel geometry and weight as well as what type of load it is supporting. It is therefore impossible to provide a m2 rate as it is different for every member. Please contact Permax if you require pricing for your project.

Can the intumescent be applied on galvanised steel?

For the Nullifire SC902 intumescent system. Please consult Permax for more information on how to deal with galvanised substrates.

Does the intumescent system need a primer?

Water based intumescent systems do require a primer.

The Nullifire SC902 system can adhere directly to the steel substrate, however a primer may be required due to the exposure classifications of the environment. Please contact Permax for more information.

How is the product applied?

Intumescent systems are applied using conventional airless spray equipment however small areas can usually be repaired using the Nullifire intumescent system. Please contact Permax for more information.

How many application coats does the product require?

A water-based intumescent system is applied in 600 micron coating thicknesses until the desired dry film thickness is reached.

The Nullifire SC902 Hybrid intumescent system can be applied up to 6mm in one coat if required.

Who provides the certification for the fire protection?

Depending on the State in which the project is carried out the approved applicator/subcontractor applying the intumescent system would supply the certification

Can we achieve 120/120/120 in using Nullifre product?

The three numbers represent the FRL structural adequacy, integrity and insulation. Generally, intumescent paint for structural steel can only achieve the fire protection for the structural adequacy. An intumescent coated steel member could not prevent the smokes movement and temperature rise of an area. Therefore, Nullifire intumescent paint can only achieve 120/-/- (or 90/-/- & 60/-/-) for structural steel.

Is there a warranty for the product?

Permax can provide a warranty for the intumescent paint system applied on your project. A warranty must be requested prior to the start of any project and be in accordance to a Permax specification.

What is the benefit in core filling hollow section steel columns?

Core-Filling reduces the required thickness of intumescent coating by reducing the effective section factor Hp/A, which therefore can reduce the fire protection costs. The core-filling methodology is required to be approved by the project engineer.

Which intumescent product should I be using?

Nullifire products are designed to excel in different circumstances, so selecting the right one for your project requirements is essential. Please do not hesitate to contact Permax to understand which intumescent system would be right for you.

Does Nullifire SC902 have to be applied on-site or off-site?

It can be applied on-site or off-site. Nullifire SC902 is a Low VOC (Volatile Organic Compounds) intumescent, allowing it to be applied on-site. However, because Nullifire SC902 is also a very durable intumescent system, it can be applied off-site and transported to site for erection. Once the steel is erected, all the connections must be coated in Nullifire SC902 or protected using intumescent bolt caps.

Five Fire Prevention Tips to Ensure Safety in your Building

The goal of a fire safety plan is to ensure that not only do you mitigate the risks of the fire, but most importantly, that you secure the highest chance of survival for all in the building. A key is to have a safety plan, to test it regularly and – though less discussed when it comes to talking about keeping people safe, making sure that you employ both active and passive fire protection systems to reinforce your structure’s fire safety. There are a few other tips which we think you may also want to consider.
water-based intumescents have a lot of advantages over other fire rating options.
