What Tenmat does
Tenmat is a privately held UK-based manufacturer of passive fire protection materials and components, headquartered in Irlam, Greater Manchester, with origins dating to 1914 (over 100 years of operation). The company designs and manufactures intumescent materials (the FF-series including FF102, FF104E, FF107, FF108, FF109, FF120/130), ventilated cavity fire barriers (VFB 60/60, VFB 120/120, VFB Plus, CavGuard lines), mechanical and electrical service penetration products (pipe fire sleeves, OverSleeves, socket box inserts and covers), fire-rated ventilation products, and Firefly millboards for high-temperature technical insulation. Its technical proposition is grounded in proprietary intumescent chemistry and a state-of-the-art in-house F-Lab fire testing furnace capable of exceeding 1200°C, supplemented by a Training Academy for installer education. The company operates multiple wholly-owned brands including PFC Corofil (Chessington, UK), BrandGuard Vents (California, USA), and Tenmat Inc (Delaware, USA), with additional operational presence in the Czech Republic, Italy, France, and Germany.
Tenmat serves seven primary vertical segments: house builders, cavity fire barriers for façades, brickwork, insulation schemes, marine, modular and offsite construction, and technical insulation. Customers are predominantly enterprise construction companies, architects, contractors, and façade specialists. Named customers include AEW Architects and Designers, Bell Building Projects, Belgrade Insulations & Drylining, GRAHAM Construction, and partners TODD Architects and Like Architects on Belfast schemes including Loft Lines and Weavers' Hall.
The business model is B2B manufacturing and direct project sales. Pricing is quote-based and project-specific rather than publicly tiered. Go-to-market is sales-led with heavy emphasis on technical specification: a National Specification Manager engages architects and specifiers early in the design phase, the company delivers RIBA-accredited CPD programs, and technical staff conduct site inspections and toolbox talks. The company is bootstrapped with no disclosed funding rounds, no parent company, and no public listing, with leadership comprising CEO Dr. Kapil Chopra, Managing Director Ed Peltor, and Technical Director Dr. Daniel Reid.

Tenmat competitors and assessment
Company assessmentDirect peers
- Armacell: Armacell manufactures technical insulation including fire-rated flexible foam and pipe insulation for HVAC and industrial applications. Comparable to Tenmat's Firefly millboards and pipe fire sleeves, particularly for mechanical service protection and high-temperature technical insulation use cases.
- FSi Limited: FSi is a UK-based passive fire protection manufacturer specializing in cavity barriers, fire stops, and intumescent materials. Closely aligned product portfolio to Tenmat across ventilated cavity barriers, service penetrations, and structural fire protection, competing head-to-head in the UK construction specification market.
- Nullifire: Nullifire (part of Tremco CPG) specializes in intumescent coatings and fire-stopping sealants for construction applications. Direct overlap with Tenmat's intumescent materials (FF102-FF130 series) and firestopping sealant product lines, particularly for service penetrations and structural steel protection.
- Promat: Promat (part of Etex Group) manufactures passive fire protection boards, sprays, and penetration seals for commercial and industrial construction. Directly competes with Tenmat across fire protection materials for building facades, service penetrations, and structural fire resistance in European and global markets.
- Tremco CPG: Tremco Construction Products Group manufactures firestopping sealants, coatings, and weatherproofing solutions for building envelopes. Direct overlap with Tenmat's intumescent sealants and penetration protection products across commercial construction, particularly through its Nullifire brand.
- PFC Corofil: PFC Corofil is a wholly-owned Tenmat subsidiary that also competes as an acquired brand in the UK passive fire protection market. Direct competitor and brand subsidiary in firestopping products, particularly strong in London and Southeast England, allowing Tenmat to address multiple specification channels under distinct brand identities.
Broad incumbents
- Sika: Sika is a global specialty chemicals company producing sealants, adhesives, and firestop systems for construction and infrastructure. Overlaps with Tenmat's intumescent and sealant product lines, particularly in building envelope and service penetration applications, but at significantly greater scale.
- Hilti: Hilti offers firestop products, anchors, and construction tools globally with a direct sales-led model similar to Tenmat. Overlaps with Tenmat's service penetration products and firestopping sealants, but operates as a much larger, diversified construction technology provider with deeper R&D resources.
- 3M: 3M manufactures firestop products and fire protection accessories under its safety division. Overlaps with Tenmat's penetration seals and cavity barriers but operates across a much broader industrial portfolio with significantly greater R&D and distribution resources.
- Rockwool: Rockwool is a global leader in stone wool insulation with significant fire-rated product lines used across building envelopes. Competes broadly with Tenmat in insulation schemes and facade fire protection, but operates at much larger scale and across the full building envelope value chain.
