About our fire protection for steel beams service in Dunoon

We carry out fire protection for steel beams in Dunoon, covering the PA23 postcode district. The wider Argyll and Bute area is covered as well. The job starts with a free survey visit so the engineer's calculations are based on your actual walls, floors and loads.

We fit fire protection alongside new steelwork, and as a standalone job where steel was installed without it or building standards has asked for more. That covers boxing with fire-rated plasterboard, intumescent coatings for steel left on show, and the records building standards needs to see before signing the work off.

Worth knowing before you start

  • Damaged boxing or chipped intumescent paint should be repaired properly, not patched with ordinary filler. Small chips in a coating can usually be touched up with the same system, while a dented or holed box may need that board section replaced.
  • Boxing a single beam usually takes around a day, plus skimming and drying. Intumescent coatings need each coat to dry before the next goes on, so they can take several days depending on the thickness required and the room temperature.
  • Intumescent paint looks like an ordinary coating but swells into a thick insulating char when heated. How well it performs depends on the dry film thickness, which varies with the steel section and fire period, so it is applied to a written specification.
  • Steel does not burn, but it loses stiffness and strength as it heats. Protection is there to keep the temperature of the beam down for a set period, so the floor or walls it carries stay up while people leave.
  • Boarding is fairly clean work, but coatings need a clean, dry and well-ventilated room at a suitable temperature. Dust from other trades can spoil the surface, so painting is normally scheduled once the messy work in that room is finished.

What happens, step by step

  1. Free visit

    A short visit to Dunoon to see the job, agree what you want and check the bearings, floors and services that affect the design.

  2. Calculations

    The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.

  3. Building warrant

    A building warrant is applied for from Argyll and Bute Council, and work starts only once the warrant has been granted.

Building control and neighbours in Dunoon

In Scotland, structural alterations need a building warrant under the Building (Scotland) Act 2003, and work must not start until the warrant is granted. For Dunoon, warrants are handled by Argyll and Bute Council's building standards service. When the work is finished, a completion certificate is submitted and has to be accepted by the council.

There is no party wall notice system in Scotland. Instead, check your title deeds and, for flats, the tenement management scheme, and talk to neighbours early if the beam bears into a shared wall.

Fire protection for steel beams in Dunoon: your questions

Do you cover Dunoon for fire protection for steel beams?

Do you also work near Dunoon?

Yes. We also cover nearby towns including Helensburgh and Lochgilphead.

Is boxing in a steel beam cheaper than intumescent paint?

Usually, yes. Boxing with fire-rated plasterboard tends to cost less for steel that will be hidden. Intumescent coatings generally cost more because of the product and the number of coats needed, but they let the beam stay visible. Where either method would work, both can be priced on the itemised quote so you can compare.

Does a steel beam in a house need fire protection?

Usually, yes. Where a steel beam or column holds up part of the structure, building regulations normally require it to resist fire for a set period, commonly 30 minutes in a typical house. Building standards confirms what is needed for your property, and the protection is checked before the work is signed off.

What is intumescent paint for steel beams?

Intumescent paint is a fire-protective coating that swells when heated, forming a thick insulating layer that slows the steel heating up. It lets you leave a beam on show while still meeting fire requirements. It must be applied at a specified thickness over a compatible primer, so it goes on to a written specification rather than like ordinary paint.

How much does fire protection for steel beams cost in Dunoon?
