21 Jul Absolute Containers Panel Offerings: Innovative SIP Solutions for Every Building Need
When it comes to modern construction, businesses and developers are looking for building solutions that are fast, energy-efficient, durable, and cost-effective. At Absolute Containers, we manufacture and supply a comprehensive range of insulated panel systems designed to meet the needs of everything from cold rooms and modular offices to fully compliant commercial buildings.
With decades of experience in the prefabricated building industry, we offer high-quality Structural Insulated Panel (SIP) solutions that combine superior insulation, structural strength, and flexibility. Whether you’re building a temporary site office, a park home, a cold storage facility, or a permanent residential structure, Absolute Containers has a panel system tailored to your project requirements.

Industry-Leading Panel Manufacturing
Our advanced panel manufacturing facility produces a wide range of insulated panels using premium materials such as Chromadek®, FRP, IBR. Each panel is precision roll-formed with a unique tongue-and-groove joint system that ensures a secure fit and excellent thermal performance.
Panels are laminated using industrial-grade adhesives and can be manufactured with various core materials, including:
- Expanded Polystyrene (EPS)
- Polyphen (PIR/Phenolic Foam)
- Rock Wool
By maintaining strict quality controls and sourcing materials, we ensure every panel delivers exceptional durability, insulation, and long-term performance.
Our panels are manufactured to client specifications, with thicknesses and lengths tailored to specific requirements and building applications. The result is a versatile building solution that significantly reduces construction time and costs.
Flexible Panel Options
We offer EPS insulated panels in a variety of standard thicknesses:
- 40mm
- 50mm
- 75mm
- 100mm
All panels are manufactured at a standard width of 1175mm, while lengths can be customised according to project requirements.
Wall Panel Options
Our wall panels are available in two primary configurations:
Double Skin Panels
- 0.47mm Chromadek / 0.47mm Chromadek
- Ideal for prefab buildings, park homes, offices, classrooms, and modular structures.
Single Skin Panels
- 0.47mm Chromadek / 0.3mm Zincalume
- Commonly used for insulated shipping container conversions and cold storage applications.
Panels are available with either a smooth or fluted finish in Frost White, offering a clean and professional appearance.
Roof Panels
We also manufacture IBR-profile insulated roof panels designed to provide excellent strength and weather resistance. Roof panels can be incorporated into vaulted roof systems or conventional steel-truss roof structures depending on project requirements.

- 0.3mm Zincalume steel skins
- Internal 25mm steel studs at 610mm centres
- 12mm MGO fire-resistant internal board
- Polymer-modified joint filling system
- Engineered connection details and structural channels
Certified Performance
- 30-minute Fire Resistance Rating (FRR)
- Standard thermal rating of R2.2
- Upgradeable thermal performance of up to R3.7
- Acoustic performance of up to 50dB with enhanced MGO configurations
Finishing Options
A-SIP buildings can be finished in a variety of architectural styles, including:
- Smooth Chromadek
- IBR Chromadek
- Rendered plaster finishes
- Timber cladding
- Brick-slip cladding
- Stone cladding
- Textured MGO finishes
Ideal Applications
- Schools and educational facilities
- Clinics and healthcare centres
- Commercial offices
- Multi-storey buildings
- Buildings requiring formal plan approval and NHBRC enrolment
Choosing the Right Panel Core
EPS (Expanded Polystyrene)
EPS is the most widely used SIP core and provides excellent value for most applications.
Key advantages include:
- Cost-effective insulation
- Lightweight construction
- Easy handling and installation
- Good thermal performance
EPS is ideal for general building applications where affordability and performance are both important considerations.
Polyphen (PIR / Phenolic Foam)
Polyphen cores deliver enhanced thermal and fire performance for more demanding projects.
Benefits include:
- Higher insulation values
- Improved fire resistance
- Low moisture absorption
- Excellent dimensional stability
Although more expensive than EPS, Polyphen allows for thinner panels while achieving superior insulation performance.
