BS 8214:2026 – Has Fire Door Foam Been Banned? Understanding the New Standard
When BS 8214:2026 was published, many installers, contractors and fire door professionals began asking the same question:
Has fire-rated expanding foam been removed from BS 8214:2026?
The simple answer is no.
Despite discussions within the passive fire protection industry, BS 8214:2026 does not ban, exclude or prohibit the use of fire-rated expanding foam for sealing the linear gap between a fire door frame and the surrounding wall.
Instead, the revised British Standard introduces a more important principle: evidence-based compliance.
What Changed in BS 8214:2026?
One of the most significant updates within BS 8214:2026 is the move away from prescriptive product recommendations and towards performance-based specification.
Rather than telling installers exactly which materials should be used, the standard now focuses on selecting products that:
- Have appropriate independent fire test evidence
- Are suitable for the intended application
- Are installed within their tested scope
- Demonstrate proven fire performance
This reflects modern fire door installation practices and recognises that multiple products can achieve compliant fire performance when correctly tested and installed.
Compliance is no longer about selecting a particular product type simply because it has traditionally been used.
It is about selecting products with proven evidence.
Does BS 8214:2026 Allow Fire-Rated Expanding Foam?
Yes.
Fire-rated expanding foam remains an acceptable solution where it is supported by suitable fire test evidence for the intended application.
The updated standard does not state that expanding foam can no longer be used around fire door frames.
Instead, guidance relating to the frame-to-wall linear gap recognises that several sealing materials may be appropriate, including:
- Fire-rated expanding foam
- Stone wool
- Fire-resistant mastics and sealants
- Other tested linear gap sealing systems
The deciding factor is not the product category.
The deciding factor is whether the product has been appropriately tested and can demonstrate the required level of fire performance.
Evidence-Based Compliance Is the Future of Passive Fire Protection
The latest edition of BS 8214 reflects a wider shift taking place across the passive fire protection industry.
Rather than relying on assumptions, historical practice or product perception, installers and specifiers are expected to make decisions based upon:
- Independent fire testing
- Third-party evidence
- Tested fields of application
- Product performance
- Installation in accordance with manufacturer instructions
This creates greater consistency across fire door installations while encouraging manufacturers to invest in robust testing rather than relying on marketing claims.
Why FAS Fire Door Foam Remains a Compliant Solution
At Fire & Acoustic Seals, our FAS Fire Door Foam has always been developed around one principle:
Proven performance.
When installed in accordance with its tested scope and manufacturer instructions, FAS Fire Door Foam provides an effective method of sealing the linear gap between fire door frames and the surrounding structure.
Its performance is supported by independent fire testing, giving installers, contractors and specifiers confidence that they are selecting a product with appropriate evidence for compliant fire door installations.
The publication of BS 8214:2026 does not change that.
If anything, the revised standard reinforces the importance of using products that are supported by genuine fire test evidence.
Why BS 8214:2026 Benefits the Fire Door Industry
The updated British Standard provides advantages for the entire construction and fire safety sector.
Installers
Greater flexibility to use tested and proven fire stopping solutions rather than relying solely on traditional materials.
Specifiers
Confidence to specify products based on independent evidence and tested performance.
Building Owners
Fire door installations that are supported by documented fire test evidence and compliant installation practices.
Manufacturers
A greater emphasis on investment in testing, certification and product development rather than assumptions or perception.
The Most Important Question Isn’t “What Product?”
The publication of BS 8214:2026 changes the conversation.
Instead of asking:
“Which product should I use?”
The standard asks:
“Can this product demonstrate, through appropriate fire testing and evidence, that it performs as required?”
If the answer is yes, then it remains a valid solution within its tested field of application.
That is the fundamental principle behind the revised standard.
BS 8214:2026 and Fire Door Foam – Frequently Asked Questions
Has fire-rated expanding foam been banned?
No. BS 8214:2026 does not ban or exclude fire-rated expanding foam from fire door installations.
Can fire-rated foam still be used around fire door frames?
Yes. Fire-rated expanding foam can still be used where it has suitable fire test evidence and is installed within its tested scope.
Why doesn’t BS 8214:2026 mention foam in the same way as previous editions?
The revised standard has moved towards evidence-based compliance rather than recommending specific product types. The emphasis is on proven fire performance instead of prescriptive guidance.
What matters most under BS 8214:2026?
Products used within a fire door installation should be supported by appropriate fire test evidence, be suitable for the application, and be installed in accordance with the manufacturer’s instructions.
The Bottom Line
BS 8214:2026 has not removed fire-rated expanding foam from fire door installations.
Instead, it places greater emphasis on fire test evidence, proven performance and correct installation.
For installers, contractors, fire door inspectors and specifiers, the message is clear:
Compliance is no longer about choosing products based on tradition—it is about choosing products supported by robust testing and appropriate evidence.
Where supported by independent fire testing and used within its approved scope, FAS Fire Door Foam remains an effective, compliant and trusted solution for sealing the linear gap between fire door frames and surrounding walls.
