Flashing and Trims for Commercial Cold Rooms
Essential edge protection, hygienic coving, and precision vapour seals for refrigerated stores, walk-in freezers, and cleanrooms across the UK.
High-Performance Cold Room Flashing and Trims
Commercial cold room construction relies on precise perimeter sealing, insulation protection, and strict hygienic finishes. At Pirouz Ltd, we manufacture and supply a comprehensive range of flashing and trims engineered specifically for refrigeration contractors, modular cold store builders, and food processing facilities. Whether you are installing a walk-in freezer, a chilled distribution warehouse, or a cleanroom environment, our metal and PVC flashing profiles deliver clean architectural lines, protect panel insulation cores, and maintain crucial vapour seals.
Properly installed flashing and trims serve as the critical finishing layer of any insulated panel system. They cover exposed polyisocyanurate (PIR) or polyurethane (PUR) insulation cores, prevent warm moisture-laden air from penetrating joints, and protect wall-to-floor junctions against impact damage from pallet trucks and cages. Available in standard stock dimensions as well as custom folded profiles, our products ensure full compliance with British food hygiene standards while simplifying installation on site.
Technical Specifications and Material Options
Cold storage environments subject building components to extreme thermal movement, high humidity, and aggressive washdown regimes. To ensure long service life and zero thermal degradation, our flashing and trims are produced from industrial-grade materials built for rigorous trade use.
Pre-Painted Food-Safe Steel
Manufactured from 0.5mm to 0.7mm prime galvanised steel, our steel flashings feature a specialized 120-micron food-grade PVC laminate coating (PET / FoodSafe finish). This non-porous white surface resists moisture absorption, prevents bacterial growth, and stands up to frequent cleaning with chemical sanitisers.
Extruded Anodised Aluminium
For heavy-duty perimeter base channels, ceiling suspension supports, and high-impact threshold covers, we supply extruded aluminium profiles. These lightweight yet rigid profiles deliver exceptional corrosion resistance in wet processing rooms and blast chillers.
304 & 316 Grade Stainless Steel
Where maximum chemical resistance, high hygiene, or salt spray endurance is required, Pirouz Ltd provides stainless steel flashings in satin or bright annealed finishes. Ideal for fish processing, meat curing plants, and pharmaceutical cold storage.
Hygienic PVC Coving Trims
Our two-part clip-in PVC perimeter coving systems incorporate flexible soft-lip seals that conform tightly against wall and floor panels. This design completely eliminates dirt traps, ensuring compliance with strict Environmental Health regulations.
Standard Stock Profiles and Sizes
We stock an extensive array of standard flashing profiles compatible with insulated panels ranging from 50mm up to 200mm in thickness. Standard stock profiles are available in 3.0 metre lengths for fast UK dispatch.
| Profile Type | Material Options | Standard Dimensions | Primary Application |
|---|---|---|---|
| Internal Angle Trims | Food-Safe Steel / PVC / Stainless Steel | 40x40mm, 50x50mm, 80x80mm (90 degree) | Sealing internal wall-to-wall and wall-to-ceiling panel junctions. |
| External Angle Flashings | Food-Safe Steel / Anodised Aluminium | 50x50mm, 75x75mm, 100x100mm | Protecting external panel corners, column wraps, and door openings. |
| Base U-Channels | Anodised Aluminium / Galvanised Steel | 50mm, 80mm, 100mm, 120mm, 150mm track widths | Anchoring wall panels to floor slabs while forming a bottom seal. |
| Ceiling Cover Strips | Food-Safe Steel / PVC | 50mm, 80mm, 100mm flat & top-hat profiles | Concealing ceiling panel joints and suspended threaded rod fixings. |
| Flat Flashings & Sheets | Food-Safe Steel / Stainless Steel | 100mm to 300mm flat strips (3.0m lengths) | Bespoke capping, structural patching, and surface transitions. |
Thermal Efficiency and Vapour Barrier Integrity
Flashing and trims are a cornerstone of cold store thermal performance. When warm ambient air penetrates an insulated enclosure through unsealed perimeter gaps, condensation quickly accumulates. Over time, this leads to frost formation, ice build-up inside panel joints, reduced thermal efficiency, and excessive load on refrigeration compressors.
By fitting precision-engineered flashing profiles combined with approved non-setting food-safe sealants, installers create a robust outer vapour barrier. This prevents thermal bridging and maintains the thermal performance of your insulation panels throughout their lifespan.

Hygienic Compliance and Internal Integration
Meeting UK Food Standards Agency (FSA) regulations requires seamless, easily cleanable surfaces inside cold storage facilities. Square 90-degree internal corners without coving are notoriously difficult to clean, often trapping bacteria, food particles, and moisture.
Our food-safe coving systems and smooth internal angle trims create a gently curved, sealed transition between surfaces. This enables effortless high-pressure washdowns and daily sanitation routine compliance. To build a completely organized and compliant cold store, pair our flashing systems with heavy-duty modular cold room shelving systems available directly from our warehouse.
Custom Bending Services and Ordering Information
Not all cold room builds feature standard 90-degree corners or uniform structural dimensions. At Pirouz Ltd, our Harlow fabrication workshop offers rapid custom bending and folding services for non-standard flashing profiles. Send us your site measurements or CAD sketches, and our skilled metal fabricators will fold custom flashing and trims to your exact girths, hem edges, and angles up to 3.0 metres in length.
We supply refrigeration engineers, shopfitters, and maintenance contractors with direct trade pricing and fast nationwide delivery across mainland UK. All product sales and custom fabrication orders are supplied subject to our standard terms and conditions.
Frequently Asked Questions
What materials are used for standard cold room flashing and trims?
Our standard metal flashings are made from pre-painted food-safe laminate steel (0.5mm to 0.7mm thick) with a white PVC finish. We also stock anodised extruded aluminium base tracks, grade 304 stainless steel flashings, and white food-grade PVC coving trims.
Can Pirouz Ltd produce bespoke custom-folded flashings?
Yes. Our in-house fabrication facility in Harlow can fold steel, aluminium, and stainless steel sheet into custom angles, channels, or stepped profiles up to 3.0 metres long according to your specific site dimensions.
Are these flashing and trims suitable for food processing facilities?
Absolutely. All our food-safe pre-painted steel profiles and PVC coving systems feature smooth, non-porous surfaces that are chemical resistant, non-toxic, and fully compliant with UK food hygiene regulations.
What stock lengths are available for immediate dispatch?
Our standard stock flashings, channels, and coving strips are supplied in 3.0 metre lengths. This length offers maximum coverage to minimise joint lines while remaining practical for transport and handling on site.
