Fire-rated sealing for Middlebie buildings

Scotland has its own building standards: the non-domestic Technical Handbook (clause 2.1.14) says service penetrations should be fire stopped to at least the fire resistance duration of the wall or floor, with products tested for that end use. Our part is installing the specified fire-rated sealant to its tested detail.

In a building such as Middlebie Parish Church And Churchyard, any service penetration through a fire-resisting wall should be sealed to the specified detail. On estates like Broadmeadow Industrial Estate, 1.4 miles south-west of Middlebie, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal. Theatres, wards and plant rooms at sites like Annan Hospital, 5.9 miles south of Middlebie, all have compartment walls crossed by services.

Middlebie is about 15 miles east of Dumfries, in Dumfries and Galloway. We send applicators to Middlebie for service penetrations, handled exactly as we handle every other area.

About our fire stopping in Middlebie

The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints, with results classified under BS EN 13501-2. A rating such as EI 60 only holds when the product is installed as it was tested. Reproducing the tested arrangement on site is the part we take care of. Site teams most often ask us about openings found when ceilings come down for a refit and improvised or mixed-product fire seals, across joints between fire-resisting walls and floors, linear gaps at wall heads and cable penetrations. For commercial sealant work in Middlebie, you deal with one contact from quote to sign-off, whether it’s one building or several.

Hotels and care homes around smaller places like Middlebie often have services added during refurbishment. A round of checks after M&E work is good practice, and any gaps found are sealed where fire-rated sealant is specified.

Every job we finish is backed by a 12-month workmanship guarantee, in Middlebie as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

How a job runs

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Travel to smaller Scottish places like Middlebie is planned so the job is finished in one visit where possible, which is why we ask for photographs and a full list first. External joints need a dry spell as well.

  1. First we confirm the product and tested details named in the specification.
  2. We sort the openings by the detail each one needs.
  3. Old or wrong materials are cut out.
  4. Mineral wool or other backing is fitted where required.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Getting the site ready

  • Warn occupants and staff about the work
  • Share the asbestos register for older buildings
  • Let us know about inductions and permits

Advice

Aftercare for building managers

Once the work is signed off, a little attention goes a long way:

  • Keep general-purpose fillers away from compartment walls
  • File the specified details where the next contractor can find them
  • Check with the data sheet before painting over fire sealant
  • Make fire stopping part of every scope that crosses a fire-resisting wall

Give the sealant its full cure time before ceilings, boxing or decoration go over it. Not every fire-rated product can be painted, and the data sheet says which.

Keep a register of where seals are and what they are made of. It tells the next contractor exactly what to reinstate, which saves guesswork.

Different surfaces, different methods

Small ducts

Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Bigger ducts and fire-resisting ductwork are normally handled with other products.

Masonry and concrete

Openings through concrete vary from tidy cores to rough break-outs. The gap is measured at the widest point against the detail’s limits, and any that don’t are flagged.

Commercial clients in Middlebie

Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Your questions answered

Do you cover business parks and estates near Middlebie, such as Broadmeadow Industrial Estate?

Yes. Our area takes in Middlebie and its surroundings, with estates and business parks such as Broadmeadow Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.

Is a hospital such as Annan Hospital somewhere you can work?

Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.

Can you tell us what fire stopping our building needs?

No. The specification comes from your designer, fire engineer or building control. Our role is installing what they specify, to the product’s tested detail.

Do you seal openings left by new services?

Yes. Share the penetration schedule and product details and a fixed quote follows. We can follow the services contractor floor by floor so areas aren’t left open.

Can you quote from photos?

It depends on the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs usually get a visit.

How long before the joints can be used?

We will confirm how long the chosen product needs to cure.

What do BS EN 1366-3 and BS EN 13501-2 mean?

In short, BS EN 1366-3 and 1366-4 are the fire tests and BS EN 13501-2 is how results are classified. An EI 60 seal kept its integrity and insulation for 60 minutes as tested; installing to the detail is what carries that across to site.

Doing it in-house

Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.

How the quote is worked out

To price the job, we consider:

  • How much there is to seal
  • The size and state of each joint
  • The site’s rules and procedures
  • Whether the work must be split into stages

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.

Details that help us quote

To price the job accurately, we need to understand the site. Send us:

  • Photos of the joints, close up and from further back
  • Access details, including height
  • Any specification or named product
  • Where the site is, with the postcode

A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or ring 01277 525 020 or email drawings and photos if you’d rather talk the job through.
