Pipe and Vessel Insulation Services

At ThermoCore, we provide engineered insulation solutions for industrial pipework, boilers, pressure vessels, tanks and equipment throughout New Zealand — working from your drawings and models to deliver precise material take-offs, efficient manufacture and reliable project delivery.

Our Services

Hot Pipe Insulation and Pipe Lagging 

Steam lines, geothermal pipelines, hot water reticulation and high-temperature process pipework across carbon, stainless, galvanised, copper, press-fit and aluminium pipe and tube. Systems specified to hold process temperature and limit surface heat loss.

Boiler Insulation

Boilers, boiler pipework and associated hot systems insulated with high-temperature materials including calcium silicate, Rockwool and aerogel, finished in metal cladding for durability and safe surface temperatures.

Cold Pipe Insulation

Chilled water, ammonia, glycol, and refrigeration pipework, insulated and vapour-sealed to prevent condensation, ice build-up and corrosion under insulation (CUI).

Pressure Vessel and Tower Insulation

Engineered insulation for pressure vessels, columns and towers, including preformed and prefabricated systems supplied ready for site assembly.

Tank Insulation

Storage and process tanks insulated and clad for thermal performance, temperature holding and durability in service — from small process vessels through to large-capacity site tanks.

Equipment and Ducting Insulation

Thermal and acoustic insulation for plant equipment and industrial ducting systems.

Cladding and Jacketing

Stainless steel 304, stainless steel 316, aluminium 6061, and aluminium foil cladding, jacketing and custom labelling — the weatherproof, mechanically durable finish that protects the insulation system underneath.

Removable Insulation Covers

Reusable insulated covers for valves, flanges, steam traps and other fittings requiring regular access, so maintenance does not mean destroying and rebuilding the insulation each time.

Industries We Support

Insulation Products and Materials

We specify from a full material range rather than a single product line, matching material to operating temperature, operating pressure, and environmental conditions.

Aerogel (ArmaGel XGH)

High performance, thin profile, for space-constrained and high-temperature applications.

Service Temperature Range: +20 to +650 degrees Celsius.
Product Form Type: Blanket, Roll

Up to 50% thinner than other insulation products, up to 25% savings on metal cladding, water repellent, breathable, reduced system weight. 

Foamglas (Cellular Glass)

Closed cell, non-combustible, and moisture resistant

Service Temperature Range: -260 to +480 degrees Celsius.
Product Form Type: Preformed sections, blocks

Moisture impermeability, non-combustible, chemical resistant, high compressive strength, can handle highly fluctuating temperature systems.

Phenolic

High performance rigid foam.

Service Temperature Range: +1 to +150 degrees Celsius.
Product Form Type: Preformed Sections, Block

Moisture resistant, resistant to chemicals, moderate compressive strength. 

Polyisocyanurate (PIR)

Dual range insulation application. 

Service Temperature Range: -180 to +120 degrees Celsius. 
Product Form Type: Preformed Sections, Blocks

Very low thermal conductivity, vibration resistant, low friability, chemical resistant.

Ceramic Fibre

Extreme temperature applications.

Service Temperature Range: +651 to +1200 degrees Celsius.
Product Form Type: Preformed Sections, Blanket

Extreme thermal tolerance, very low thermal conductivity, shock resistant, low thermal energy storage. 

Rockwool

Mineral wool for hot systems and fire performance.

Service Temperature Range: +32 to +650 degrees Celsius.
Product Form Type: Preformed Sections, Slabs, Blanket, Wired Mat

High performance, easier to handle, suitable for heavy duty applications, moisture repellent. 

Armacell

Flexible elastomeric systems for cold and chilled service

Stainless Steel Cladding

Stainless Steel Cladding comes in grade 316 and grade 304 with a natural finish

Aluminium Cladding

Aluminium Cladding comes in grade 6061. Lighter than stainless steel. Comes in white and natural finishes. 

Aluminium Foil Cladding

Thin layer of Aluminium Foil applied to the insulation material in production. Easier to install, no additional cladding to be applied. 

Jacketing and Removable Covers

Removable covers applied to equipment within a pipework system allows for easier maintenance and serviceability 

Custom Labelling

Adhesive labels that indicate what’s inside the pipework, tank, or pressure vessel and the direction of flow. 

Want to Be Strategic?

We are problem solvers and we understand the cost of fabrication and materials.

If you have an engineered design, we have the capacity to prefabricate the system in accordance with ASME IX standards — including NDT testing, purging, x-ray and hydrotesting — then pre-insulate it with our offshore ISO9001 accredited supply partners.

The completed system is ocean freighted to site, where our local partners assemble it.

This saves investment, ensures accuracy and reduces downtime during plant shutdowns.

Insulation Services FAQs

Does ThermoCore insulate boilers?

Yes. Boiler insulation is a core capability, alongside steam lines, geothermal pipelines and hot water reticulation, using high-temperature materials such as Rockwool and aerogel with metal cladding.

Yes. We insulate and clad storage and process tanks of all sizes, specifying material and thickness against contents temperature, ambient conditions and the thermal performance the process requires.

Reusable insulated covers fitted to valves, flanges, steam traps and other components requiring regular access. They allow maintenance without cutting away and rebuilding fixed insulation, which reduces downtime and long-term insulation cost.

Yes. Send your CAD model or detailed drawings and project location, and we produce precise material take-offs, prefabrication and an accurate quote from them.

Where you have an engineered design, we prefabricate the piping system offshore under ASME IX welding standards, including NDT testing, purging, x-ray and hydrotesting, then pre-insulate it through our ISO9001 accredited supply partners before shipping it to site for assembly.

Stainless steel 304, stainless steel 316, aluminium 6061 and aluminium foil cladding, plus jacketing and removable covers, with custom labelling available for pipework, tank, and vessel identification.
