About our fire protection for steel beams service in Bowthorpe

If you live in Bowthorpe, fire protection for steel beams can usually be planned and priced after a single survey visit. Bowthorpe is around 3.4 miles from Norwich, and we cover both. We cover NR2, NR4, NR5, NR6 and NR8, and we fix the price in writing once the layout and scope are agreed.

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

What to expect

  • Boxing is generally the lower-cost route for steel that will be hidden. Intumescent coatings cost more because of the product and the number of coats, and the price rises with the fire period and the size of the section.
  • Exposed steel is popular in open-plan kitchens and loft spaces. An intumescent system can take a decorative top coat in most colours, although up close the finish has a slightly textured look compared with steel painted in a factory.
  • 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.
  • 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.
  • Older homes sometimes have steel fitted decades ago with no protection at all, or boxed in ordinary timber and hardboard. When this turns up during other work, we can check what is there and price protection to suit today's requirements.

From survey to sign-off in Bowthorpe

  1. Free visit

    A short visit to Bowthorpe 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 control

    We submit a building notice or full plans application to the local council's building control team, so approval is in place before the wall is touched.

  4. Steel in, made good

    On site we prop, open up, fit and pack the steel, then fire protect, box in and plaster once the inspection is done.

Building control and neighbours in Bowthorpe

Structural openings in English homes need building regulations approval before work starts. The local council's building control team can deal with it, or you can use a registered building control approver. Either way the steel is inspected before it is covered, and a completion certificate is issued at the end. Keep it safe for when you sell.

Terraced and semi-detached homes often need party wall notices, because cutting into a shared wall to take a beam end is notifiable under the Party Wall etc. Act 1996. Allow at least two months for the notice period unless your neighbour agrees sooner.

Questions about fire protection for steel beams in Bowthorpe

Do you also work near Bowthorpe?

Yes. We also cover nearby towns including Norwich, Great Yarmouth and Thetford.

Do I need a party wall agreement for fire protection for steel beams in Bowthorpe?

Yes, if the beam bears into a shared wall: the Party Wall etc. Act 1996 applies in England and Wales, and a party structure notice must be served at least two months before that work starts. We arrange it through a party wall surveyor.

How long does intumescent paint take to apply?

Several days in most cases. Each coat has to dry before the next is applied, and the number of coats depends on the thickness needed. Cold or damp rooms slow drying, so the space is kept warm and ventilated, and the top coat goes on once the full build has been measured.

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 thick does intumescent paint need to be on a steel beam?

There is no single figure. The thickness depends on the steel section, how many sides are exposed and the fire period required, and the coating manufacturer's data sets the dry film thickness for each case. The applied thickness is measured with a gauge once the coats have dried and recorded for building control.

Who approves fire protection for steel beams in Bowthorpe?

Structural work in Bowthorpe needs a building notice or full plans application to the local council's building control team or a registered building control approver. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.
