Fire stopping for commercial buildings in Clate

Most of our fire stopping work happens after the building is up. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind, often unnoticed. We close the openings listed on your schedule, using the specified sealant and detail. If you have seals that don’t match their tested detail and builders’ foam or ordinary silicone in compartment walls, we can put it right, on small duct penetrations where the tested detail allows, service gaps in risers and cable penetrations alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Clate, that means joint design, primers and backing rod as standard.

Hotels and care homes around smaller places like Clate often have services added during refurbishment. We fit the specified fire-rated sealant as its published detail shows and raise it if another product is needed.

We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

What we are called out for in Clate

Physical damage is another reason seals stop doing their job. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped and the opening isn’t always resealed.

It’s worth sending us details if you spot any of the following:

  • Open linear gaps along the top of fire-resisting walls
  • Fire sealant pulled out of the opening
  • Damaged fire seals in risers and voids
  • Unsealed openings around new pipes and cables

For any site around Clate, we work to the specification and the manufacturer’s installation guidance, leaving design and sign-off with the designer.

Our contractor checklist

Diagnose, treat, sign off

Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you. Travel to smaller Scottish places like Clate is planned so the job is finished in one visit where possible, so photos, sizes and a full list matter. External joints need a dry spell as well.

  1. First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  4. Mineral wool or other backing goes in wherever the detail asks.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Before we start on site

  • Move anything stored against the joints
  • Point out any areas we must not close
  • Warn occupants and staff about the work

Surface by surface

Plastic pipes

In a fire, plastic pipework melts away and leaves an opening. Some intumescent sealants are tested on smaller plastic pipes, but many need a collar or wrap. We check the pipe material and diameter against the detail before we start.

Metal pipes

Metal pipes conduct heat, so their details often call for extra measures along the pipe, and the tested detail may ask for insulation beyond the wall. If the detail needs something beyond sealant, we tell you.

Building owners, agents and FMs in Clate

Building owners and managing agents use us on everything from one building to a spread of sites around Clate. Several sites can go on one quote, so there’s one set of paperwork to deal with.

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, and our applicators hold CSCS cards.

What we can’t put right

Honesty saves time and money. Fresh joints won’t solve:

  • Plastic pipes whose detail calls for a collar or wrap
  • Walls or floors that aren’t fire-resisting to begin with
  • Designing or specifying fire stopping, which sits with the designer or fire engineer

If in doubt, call 01277 525 020 or use the quote form and we’ll say what we think.

Where we work in Clate

  • Small duct penetrations where the tested detail allows
  • Service gaps in risers
  • Linear gaps at wall heads
  • Cable penetrations
  • Joints between fire-resisting walls and floors
  • Pipe penetrations

Compartment walls and floors in Clate

Work on Clate has to fit the ferry timetable and the forecast. We need the specification and a count of penetrations before we sail. In Scotland, clause 2.1.14 of the non-domestic Technical Handbook expects service penetrations to keep at least the fire resistance duration of the wall or floor, with proprietary products, intumescent ones included, tested for their end use. We install what’s specified, to the product’s tested detail.

Buildings near Clate get the fire-rated product that’s specified, installed to its tested detail.

Clate is about 13 miles north of Lerwick, in the Shetland Islands. Commercial clients in Clate use us for work on service penetrations. Clate is one of 63 places in the Shetland Islands on our list for service penetrations.

Anyone looking for fire stopping in ZE2 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed. Among the streets we cover are Rocky Road and Harlsdale. We also cover Sandwick (1 mile north), Symbister (1 mile north), Hamister (1 mile north), Huxter (1 mile east) and Tripwell (2 miles north-east) for service penetrations. Further afield, our area takes in Lerwick (13 miles south), Sound (14 miles south) and Brae (12 miles west). For island and remote sites, we plan travel and materials carefully.

Aftercare for building managers

Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:

  • Check with the data sheet before painting over fire sealant
  • Have penetrations checked while they can still be seen
  • Keep product data and details in the fire safety file
  • Look above ceilings when tiles are lifted for other jobs

Keep the product data and installation details with the building’s fire safety information. It makes later repairs much easier to match.

Make reporting new openings part of every permit to work in service areas. It costs little and catches breaches early.

Your questions answered

How do the Scottish rules apply to fire-rated sealing in Clate?

The non-domestic Technical Handbook, clause 2.1.14, expects a penetration to keep at least the wall or floor’s fire resistance period, with proprietary products tested for the use they’re put to. The detail is set by the designer and goes through the warrant process; we install the specified product to its tested detail.

Will you design a fire-stopping scheme for our building in Clate?

No. Fire-stopping design and sign-off belong to the designer, principal designer, fire engineer or building control. Our part is installing the specified product to its tested detail, and telling you if the detail calls for something other than sealant.

Is the work guaranteed?

Yes. Workmanship is guaranteed for 12 months on every job.

Do your applicators hold CSCS cards?

Yes. If you need card details for site access, tell us and we will confirm them with the quote.

Can you quote from photographs?

That depends on the size and complexity of the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Is Clate in your area?

Yes. We cover Clate, and the simplest way to start is to give us a call on 01277 525 020 or email drawings and photos.
