A fast answer fire for fire protection

A new intumescent coating speeds the build of a retail development with onsite application using the only water-based coating on the market offering 30-120 minutes fire protection.

Like many new and challenging retail projects, the Primark store in Glasgow’s Argyll Street has been constructed to a tight schedule. Various techniques were used to ensure that the timetable could be met – including the use of a new intumescent coating from Nullifire.

Nullifire S707 -120 is the latest addition to the company’s established range of water-based intumescent coatings. In line with the current need for extended fire protection, it offers fire resistance for internal structural steel for up to 120 minutes. However, despite these performance advantages, Nullifire S707-120 is also ideal for rapid application.

Unlike solvent based multiple coat systems that can remain soft for months, Nullifire S707-120 dries quickly cutting application time by up to a half, and provides a smooth hard finish which is attractive enough to leave as the final surface.

John Aitkin, Technical Services Manager for Nullifire explains one of the reasons for the success of Nullifire S707-120 is due to its ability to provide the thickness of coating required for 2 hour fire protection in reduced time.

"Nullifire S707-120 offers faster drying time thanks to its Hi-Solids content and Hi-build technology. It can be applied faster by spray or brush as the project requires, and because it is water-based there are none of the health and safety worries inevitable with solvent-based products. S707-120 is also fully tested to BS 476: Part 20-21: 1987 for up to 120 minutes fire protection, and is fast and easy to apply by spray or brush. It is also ICF Compliant and Certifier Approved - three key standards every specifier and contractor should look for in an intumescent water-based fire protection coating."

Specialist contractors AP Orr Fire Protection used 2000 drums of S707-120. Malcolm Stuart is the managing director of AP Orr. He praises Nullifire S707-120 for its ease and speed of application. "We were pleased to see Nullifire specified as the supplier. We found the 120-minute version of their product very easy to apply. It is easy to get up to thickness, and it meant we could complete the job faster – which was ideal for us as well as the following contractors who could get on to site quicker as a result."

A Safe Innings at The Rose Bowl

Nullifire S607 and S605 decorative intumescent coatings provide fire protection for all structural steelwork in the recent redevelopment of the west end of The Rose Bowl, the Hampshire County Cricket Ground.

Safety and aesthetics were the key issues facing specifiers for the fire protection and decoration of the supporting steel structure of the new west end stand at The Rose Bowl, the county home of cricket in Hampshire. Both criteria, as well as exceptional cost effectiveness, were met by Nullifire Systems S607 and S605.

Nullifire S607 is a fast drying water-borne intumescent basecoat for internal use. Nullifire S605 is a high performance external grade intumescent coating. Both have been extensively proven in use, as well as in independent tests, for up to 2 hours fire resistance to BS 476: Part 20/22. They are easy to apply by spray or brush.

A hard, protective finish was provided by Nullifire S615 semi-gloss acrylic Top seal. This robust, highly decorative seal is suitable for internal and external application. Available in any BS or RAL colour, white was, appropriately, selected for the Rose Bowl. The durability and UV resistance of S615 ensures that, rain or shine, the colour remains bright and undimmed. And whatever might happen on the pitch, spectators in the west end can watch, secure in the knowledge that they are seated beneath a structure protected by the UK’s leading supplier of passive fire protection systems: Nullifire.

The Nullifire fire protection systems were applied by Fire Technology Ltd., of Margate, Kent (Tel. 01843 228899). Main contractor was Powells Shopfitting Services Ltd.

Nullifire Safety for New Stadium

Nullifire fire protection systems for structural steel, as well as gap and penetration seals, were chosen in the construction of the new home of Southampton Football Club, the 36,000 seat capacity St Mary’s Stadium.

With safety an absolute priority, specifiers looked to the solid reputation for quality and reliability of Nullifire fire protection systems in the construction of St Mary’s Stadium, the new home of Southampton Football Club. The thorough and expert technical support provided by Nullifire, together with the exceptional cost effectiveness of Nullifire products, were also key factors in the selection of Nullifire systems for this major development.

Nullifire S607 was applied at a 1 hour fire rating to the internal structural steelwork, including universal beams, columns and hollow sections. Used with TS616 acrylic Top seal, these systems provide a wholly water-based passive fire protection system – easy and safe to apply by spray or brush even in confined areas. Fast drying, the Nullifire water-based systems also ensure that work can proceed with minimum delay, thus helping early contract completion. Nullifire TS616 provides a hard, protective seal for the S607 basecoat, offering a fully tested fire protection system with up to 2 hours fire rating to BS 473: Part 20.

For external steelwork, Nullifire S605 high performance grade intumescent basecoat was chosen, with TS615 Top seal providing an exceptionally durable finish with high weathering and UV resistance. The specifiers for St Mary’s chose a white finish from the extensive range of BS and RAL colours available.

Gap and penetration seals

Internally, Nullifire fire stop seals and fire barriers were used to seal construction joints and service penetrations. Nullifire’s fire stopping products include System J2000 intumescent compressible strip, M701 Acrylic Mastic and M703 Silicone Mastic, B240 Fire Rated Compound, B805/B10 Lightweight Fire Curtains, as well as Pipe Wraps and Pipe Collars for all sizes of pipe, and the Nullifire Multi-fit Collar for 55, 82 and 110mm pipework.

For the main part of the stadium construction, Nullifire fire protection systems were applied by Boss Fire Protection (Tel. 0141 620 1331). Nullifire fire protection within the corporate hospitality area under the stadium was applied by Elite Fire Protection of Southampton (07885 660778). Main contractors were Barr Construction.

Nullifire S706 – You Can Bank On It

Nullifire S706 intumescent coating for structural steel has been installed by Fireseal Contracts Limited in the major new office development in Spinningfields, Manchester for The Royal Bank of Scotland. Now, as work proceeds on the fit out, Nullifire B240 Fire Stopping Compound, M701 Fire Resistant Sealant, and B735 Fire Rated Batts are being used to seal penetrations and construction joints.

Nullifire S706, launched earlier this year, combines the latest advances in Hi-build, Hi-solids technology to save time and costs on site. This exceptionally efficient and fast drying intumescent coating enables fast track, on-site application and is suitable for protection and decoration of all internal and semi-exposed structural steelwork. Nullifire S706 is fully tested to BS 476: Part 20-21: 1987 for up to 90 minutes fire protection.

Thinner film, faster application

The Hi-solids content and solvent blend formulation of Nullifire S706 means outstandingly efficient coverage: less material is needed to achieve the required level of fire protection. Up to 1.4mm thickness of wet product can be applied in a single coat, reducing application time, reducing overall site costs, and preventing delays to other trades.

Ready and easy to use

S706 is ready for use (requiring no thinning) and easy to spray using conventional or automated spray systems. S706 may also be applied by roller or brush. Nullifire S706 dries to a smooth white finish, and in non-decorative areas of C1 and C2 buildings there is no need for a top seal.

At the new Royal Bank of Scotland offices the Nullifire S706 intumescent coat is protected by Nullifire S715 Top Coat, available in a range of RAL or BS4800 colours. S715 Top Coat provides a robust, satin finish which is easy to maintain simply by wiping with a damp cloth. This makes it ideal for situations where the structural columns or beams are left uncased. Furthermore, S715 contains no fibres, so is suitable for areas where delicate electronic instruments are manufactured or used.

Applicator delighted

This is the first time Fireseal Contracts have used Nullifire S706. Contracts Manager Peter Gray declared that he was delighted not only with the product, but also the outstanding service provided by Nullifire – so much so that the company has insisted on Nullifire S706 for their next large project, due on site later in the year.
