Protherm Light
Premixed lightweight thermal-insulating plaster · Edilteco
Applied products live or die by their build-up evidence: the substrate, the applied thickness, the configuration tested — and whether any of that matches what the project is proposing.
Protherm Light is a premixed, lightweight thermal-insulating plaster for fire protection from Edilteco — a partner-supported product area for The Bench. It comes up in fire protection and thermal build-up discussions, and the questions are almost always about what the evidence covers rather than what the brochure says. This page sets out the typical questions, the evidence commonly reviewed, and how to get a specific build-up question answered in writing.
ScopeEvidence review. Not certification, Building Control or design sign-off.
When an applied protective layer is in the build-up discussion
Use this page if Protherm Light — or an applied thermal-insulating plaster like it — is being discussed for a fire or thermal role in a build-up, and someone needs to check the evidence before the detail is fixed. Applied products add variables that board products don't: applied thickness, substrate preparation, the tested configuration. This page is organised around those questions.
The relationship is stated so that it is visible. It does not imply certification, approval, endorsement or guaranteed acceptance of the product or any build-up.
The questions that usually arrive with this product
What fire evidence exists for this substrate and applied thickness?
Fire evidence for applied products is tied to what was tested — the substrate, the thickness, the configuration.
Does the tested configuration transfer to the one we're proposing?
Evidence for one configuration may be relevant to another, but that read-across is a review question, not an assumption.
What role can it play in the thermal performance of the build-up?
The thermal contribution is a question of what the evidence supports for the build-up as a whole, not a headline value.
How do applied thickness, density and coverage relate to the documents?
The values in the documents carry application assumptions that the site reality has to match.
What quality and installation records should exist for the application?
For applied products, the installation record is part of the evidence story, not an afterthought.
What will the project team expect to see before relying on the layer?
Organising the evidence before the question hardens is usually cheaper than answering it afterwards.
The paperwork behind applied protection questions
- Fire test evidence and classification reports for specific tested configurations
- Assessment reports and field of application details
- Thermal performance information, where a thermal role is proposed
- Technical datasheets and declared values
- Application and installation guidance — substrates, preparation, thickness control
- System build-up evidence, where the applied layer is one component of an assembly
- CE/UKCA documentation and declarations, where applicable
Available evidence can be reviewed against the intended use — substrate, thickness and configuration compared line by line against what was actually tested or assessed.
Manufacturer data describes the product. It is not independent proof of how it performs in a particular build-up.
Clear about the limits of the review
The Bench does not certify, approve or replace project-specific design responsibility. In particular, the review does not provide:
Not part of the review
- Certification or approval of the product or any system using it
- Building Control or other statutory sign-off
- Warranty or guarantee decisions for the product or build-up
- Design responsibility for the fire or thermal detail
Fire and thermal conclusions for a project remain with the appointed competent person or organisation. Our written review is there to support them, not replace them.
Where Protherm Light questions usually resolve
Protherm Light questions may be relevant to these evidence areas. They are reading routes, not evidence about the product.

- Thermal & U-valuesThermal performance evidence
- System build-upsThe applied layer as part of an assembly
- Façades & external wallsWhere protective layers meet external wall build-ups
These links go to manufacturer or product-owner information. The Bench's review stays evidence-led.
A written evidence position for the build-up actually proposed
- Review Protherm Light evidence against the build-up actually proposed
- Check whether tested configurations cover the proposed substrate and thickness
- Frame the thermal role accurately — what the evidence supports, and what it doesn't yet show
- Help identify evidence gaps and what would close them
- Provide a written review note, gap register or evidence summary the project team can use
