What should Gwynedd projects plan for?
For Caernarfon businesses that share a building, we keep noise, dust and deliveries to agreed windows so neighbours are not disturbed.
For Caernarfon buildings with older timber floors or plastered ceilings, we check fixings and deflection on survey so the partitions stay true once the building moves with the seasons.
How much do fire rated partition walls cost in Gwynedd?
The required duration (30, 60 or 90 minutes), number of fire board layers, wall height and the extent of fire stopping around services and at the head set the price. Typical lead time: 1–3 weeks. Guide prices, supply and install — fixed after a free survey.
Why choose us in Gwynedd?
Clear guide prices online
Our fire rated partition walls prices are published as guide ranges, so you can budget before the survey.
Fixed price, in writing
Your quote lists the system, glass, doors, finishes and any extras, so the figure you approve is the figure you pay.
Acoustic bonus
Multi-layer fire walls are also good acoustic walls, so plant rooms and stair enclosures keep noise away from the surrounding office.
Penetrations planned
Services crossing the wall are coordinated in advance and sealed with tested products, which is where most fire walls actually fail in inspections.
Office fit-outs often include walls that have a fire job to do: corridor walls on a protected escape route, enclosures around stairs, risers and plant, and walls that separate tenancies or compartments. A fire rated partition wall is built using the board manufacturer's tested system, specifying stud size, board type and number of layers, fixings, insulation and how the head and junctions are detailed. Follow that system and the wall carries its classified rating; deviate from it and the rating no longer applies.
Key specifications
| Boarding | One to three layers of 12.5mm or 15mm fire-resistant plasterboard each side |
|---|---|
| Insulation | Mineral wool to the system specification |
| Fire stopping | Tested collars, wraps, sealants and batts for every penetration |
| Acoustic performance | Approx. Rw 45–55 dB depending on build-up (lab) |
Surveys across Gwynedd
Survey visits across Gwynedd — including Caernarfon, Caernarfon and Holyhead — are free and carry no obligation. We measure, photograph and note services so the quote is accurate first time.
In Wales, the Building Regulations apply with Welsh-specific guidance, so we flag anything that may need Building Control — usually fire or escape-route changes — at survey stage.

Fire Rated Partition Walls in Gwynedd: FAQs
How much do fire rated partition walls cost in Caernarfon?

What makes a partition wall fire rated?
A partition wall is fire rated when it is built to a manufacturer's tested system, using the specified studs, fire-resistant boards, insulation, fixings and head detail, and installed exactly as tested. Every service penetration must also be fire stopped with compatible tested products. Using fire board alone does not make a wall fire rated.
Who signs off a fire rated partition wall?
Where walls affect escape routes or compartmentation, Building Control normally reviews and inspects the work. Your fire risk assessor will also want evidence for the fire risk assessment. We hand over the system classification, fire-stopping records and photographs so both can verify what was built.
