Estimating Costs for Fire-Rated Stud Walls: A Guide to Fire-Rated Wall Pricing

When it comes to building or renovating commercial or residential spaces, fire safety is a top priority. One key element in fire safety is the installation of fire-rated stud walls. These walls help contain fires and protect occupants, giving crucial extra time for evacuation. But if you’re planning a project, you’ll want to understand the costs involved. In this post, I’ll walk you through the basics of fire-rated stud walls and how to estimate their costs. I’ll also share practical tips to help you plan your budget effectively.

Understanding Fire-Rated Wall Pricing

Fire-rated walls are designed to resist fire for a specific period, usually measured in minutes or hours. The price of these walls depends on several factors, including materials, labour, and the fire rating required.

The main components that affect fire-rated wall pricing include:

• Type of studs: Steel or timber studs are commonly used. Steel tends to be more expensive but offers better fire resistance.

• Fire-rated plasterboard: Special boards are used to increase fire resistance. These cost more than standard plasterboard.

• Insulation: Fire-resistant insulation may be needed inside the wall cavity.

• Labour costs: Skilled installers are required to meet fire safety standards.

• Wall size and complexity: Larger or more complex walls will cost more.

  
  

For example, a simple fire-rated stud wall in a small office might cost less than a large wall with multiple layers of fire-resistant materials in a commercial building.

When estimating costs, it’s important to get quotes from experienced installers who understand local building codes. This ensures your wall meets safety standards without overspending.

Materials That Affect Fire-Rated Stud Wall Cost

The materials you choose have a big impact on the overall cost. Here’s a breakdown of the main materials used in fire-rated stud walls:

1. Studs

2. Steel studs are non-combustible and preferred for fire-rated walls. They cost more but provide better durability.

4. Timber studs are cheaper but may require additional treatment to meet fire ratings.




5. Fire-rated plasterboard

6. These boards contain additives that slow down fire spread.

8. They are thicker and heavier than regular plasterboard, which adds to the cost.




9. Insulation

10. Mineral wool or glass wool insulation is often used for fire resistance.

12. This adds to both material and installation costs.




13. Fixings and accessories

15. Fire-resistant sealants, screws, and tapes are necessary to maintain the wall’s integrity.

Choosing the right combination depends on your project’s fire rating requirements and budget. For example, a 1-hour fire-rated wall might use a single layer of fire-rated plasterboard on each side, while a 2-hour wall could require double layers and thicker studs.

How thick is a 1 hour fire-rated wall?

A common question is about the thickness of a 1-hour fire-rated wall. The thickness depends on the materials used and the construction method. Typically, a 1-hour fire-rated stud wall will be around 100mm to 150mm thick.

Here’s a typical setup for a 1-hour fire-rated wall:

• Studs: 70mm to 90mm steel studs

• Plasterboard: One layer of 12.5mm fire-rated plasterboard on each side

• Insulation: Mineral wool insulation filling the cavity

  
  

This combination provides the necessary fire resistance while keeping the wall reasonably slim. Thicker walls with more layers or wider studs are needed for higher fire ratings.

If you need a specific fire rating, always check with your installer or supplier to confirm the exact wall thickness and materials required.

Labour and Installation Costs

Labour is a significant part of the total cost. Installing fire-rated stud walls requires skilled workers who understand fire safety regulations and building codes. Poor installation can compromise the wall’s fire resistance.

Labour costs vary depending on:

• Project size: Larger projects may benefit from economies of scale.

• Complexity: Walls with doors, windows, or curves take longer to install.

• Location: Labour rates in Shrewsbury and Shropshire may differ from other regions.

  
  

On average, labour can account for 40% to 60% of the total cost. It’s worth investing in experienced installers to ensure the job is done right the first time.

Tips for Budgeting Your Fire-Rated Stud Wall Project

Here are some practical tips to help you estimate and manage your fire-rated stud wall costs:

• Get multiple quotes: Contact several local installers to compare prices and services.

• Specify your fire rating: Be clear about the fire resistance level you need to avoid overpaying.

• Consider materials carefully: Balance cost and performance by choosing the right studs and plasterboard.

• Plan for extras: Include costs for doors, trims, and fire-resistant sealants.

• Check local regulations: Ensure your wall meets Shropshire building codes to avoid costly rework.

• Ask about warranties: A good warranty can save money if issues arise later.
