Fixing Accessories for Cold Rooms & Insulated Panels
Selecting the correct fixing accessories is crucial when constructing, repairing, or refurbishing commercial cold storage facilities, cleanrooms, and food processing environments. Pirouz Ltd supplies a comprehensive range of high performance fixing accessories engineered specifically to secure insulated polyurethane and polystyrene panels without compromising structural strength or thermal efficiency. From heavy duty ceiling suspension brackets to thermal break nylon fasteners, our stock ensures tight panel joints, seamless hygenic finishes, and long term durability.
Based at our distribution warehouse in Harlow, Essex, we serve contractor networks, maintenance engineers, and commercial refrigeration specialists across the UK. All our fixing accessories are manufactured to strict technical tolerances, offering maximum corrosion resistance and moisture protection in high humidity and sub zero operational environments. Explore our range below or contact our technical sales desk for advice on material selection and bulk trade orders.
Commercial Grade Panel Fixings and Structural Fasteners
Cold room constructions present unique structural and thermodynamic challenges. Standard masonry or timber screws are unsuitable for sandwich panel assemblies because metal fasteners create severe thermal bridges. This thermal transfer leads to condensation, ice formation, surface corrosion, and eventual insulation failure. Our specialized fixing accessories eliminate cold bridging while maintaining high tensile and shear load capacities across all temperature zones.
Whether you are assembling a small walk in chiller or a large scale industrial cold distribution warehouse, using engineered fixing accessories ensures your structure meets stringent UK building regulations and food safety standards. Every fastener, bracket, and trim capping in our catalogue is selected to complement standard tongue and groove or cam locking panel systems.
Essential Categories of Cold Room Fixing Accessories
Threaded Nylon Rods, Composite Bolts, and Thermal Anchors
Threaded nylon studs and non conductive composite rods are essential components for securing internal wall panels and joining overhead ceiling runs. The inherent low thermal conductivity of solid nylon prevents heat transfer between internal cold environments and external ambient structures. Available in standard M8, M10, and M12 diameters, these fixing accessories offer excellent mechanical strength while performing reliably in temperatures as low as minus thirty degrees Celsius.
Paired with composite nuts and wide area load distribution washers, our nylon threaded rods allow installers to pull panels tightly together without crushing the delicate insulation core. This ensures continuous vapour seals across panel joints and eliminates air leakage points.
Stainless Steel Blind Rivets, Tek Screws, and Hygienic Caps
For securing perimeter flashings, floor angles, door frame trims, and sheet metal laps, we stock corrosion resistant A2 and A4 grade stainless steel blind rivets and self drilling Tek screws. Supplied with pre fitted bonded neoprene washers, these fixings establish an airtight, moisture proof seal that prevents humidity from penetrating behind wall panels or flashings.
To preserve cleanroom integrity and facilitate thorough washdown procedures, we also supply matching white PVC hygienic screw caps and snap on dome covers. These protective caps fit snugly over screw heads and rivet faces, creating smooth, easy to clean surfaces that eliminate dirt traps and bacterial harbourage areas.
Ceiling Suspension Systems and Heavy Duty Brackets
Large span insulated ceilings require robust overhead support to prevent structural sag and maintain structural integrity under load. Our overhead ceiling suspension kits feature heavy gauge galvanised steel brackets, drop rods, load spreading alignment plates, and internal isolation bushes. These fixing accessories distribute dead weight evenly across secondary roof steelwork or purlins while allowing for minor structural expansion and contraction.
By incorporating thermal isolation bushes within the suspension connection, our overhead fixing accessories ensure that cold air within the room cannot conduct through the suspension drop rods to the building structure above.
Floor Channels, Base Angle Fixings, and Sealant Retainers
Base level stability requires rigid anchoring into concrete floor slabs, granolithic screeds, or perimeter dwarf walls. We supply heavy duty stainless steel floor tracking fixings, concrete frame anchors, non metallic shims, and PVC floor channel retainers. These fixing accessories elevate and secure wall panels above washdown water level, protecting panel bases from direct water exposure and floor heave.
Technical Specifications and Material Selection Matrix
The table below provides key physical and technical specifications for our core range of fixing accessories, helping you select the correct component for your temperature profile and mechanical load requirements:
| Product Category | Available Sizes | Primary Material | Key Performance Feature |
|---|---|---|---|
| Nylon Threaded Rods | M8, M10, M12 (1m & 2m lengths) | Polyamide PA6 / Nylon 66 | Zero thermal conduction, high tensile strength down to -30°C |
| Self-Drilling Tek Screws | 4.8mm to 6.3mm dia (19mm to 150mm length) | A2 / A4 Stainless Steel | Pre-attached neoprene washer for immediate weather sealing |
| Sealed Blind Rivets | 4.0mm & 4.8mm diameter | Aluminium & Stainless Steel | Vapour-tight body design for wet washdown environments |
| Ceiling Suspension Plates | 100mm x 100mm, 150mm x 150mm | 3mm Galvanised Steel / Nylon Bush | Spreads load over 150cm² surface area to prevent core crush |
| Hygienic Dome Caps | To suit M6, M8, M10 screw heads | Food-Grade PVC (White) | Smooth, washdown-ready surface seal resistant to chemical cleaners |
Best Practice Installation: Preventing Thermal Bridges
Proper installation techniques are just as important as selecting the right fixing accessories. When installing threaded drop rods through ceiling panels, installers should always fit mushroom head nylon load spreaders and thermal isolation washers on the internal cold face. Over tightening metal fixings directly against metal skin faces crushes the internal foam core, damages vapour barriers, and creates direct thermal shorts.
When applying base angle fixings and floor channels, ensure non setting butyl sealant or sanitary silicone is applied under the channel before driving anchors into the floor slab. This step prevents subsurface moisture from wicking upward into the panel insulation, preserving the thermal efficiency and longevity of your cold storage envelope.

Frequently Asked Questions
Why should I use nylon threaded rods instead of steel studs in a cold room?
Steel acts as a rapid thermal conductor, drawing heat from outside into the refrigerated space. This causes localized cold spots, structural condensation, and ice formation on panel surfaces. Threaded nylon rods provide mechanical support while acting as a complete thermal break, eliminating cold bridging entirely.
What size rivets are recommended for cold room flashings and trims?
We typically recommend 4.0mm or 4.8mm diameter aluminium or A2 stainless steel blind rivets. For wet processing rooms and washdown areas, sealed blind rivets with bonded washers prevent moisture and air leakage behind perimeter trims.
Do you supply complete ceiling suspension kits for insulated roof panels?
Yes, we supply modular ceiling suspension kits that include heavy duty top brackets, threaded drop rods, load spreading plates, and nylon thermal isolation bushes tailored to your panel thickness and span requirements.
How do hygienic screw caps help meet food hygiene standards?
Exposed screw heads and rivet edges create small crevices where dirt, grease, and bacteria accumulate. Snap-on PVC hygienic caps cover exposed fixings, creating a smooth, flush surface that is easy to sanitize during regular washdown procedures.
