Aerolite 103 construction delivers lightweight thermal performance for medium-rise residential and mixed-use buildings. This engineered system combines expanded polystyrene insulation with a fiber-cement or metal composite face to meet fire, acoustic, and airtightness targets.
Designed for panelized assembly, Aerolite 103 construction simplifies on-site workflows while providing consistent U-values and reduced thermal bridging. The following sections cover composition, compliance, installation details, and common questions.
| Panel Type | Core Material | Nominal Thickness (mm) | Typical R-value (m²K/W) |
|---|---|---|---|
| Exterior Wall Panel | EPS 100 | 103 | 4.1 |
| Floor Panel | EPS 100 | 103 | 4.0 |
| Roof Panel | EPS 100 | 103 | 3.9 |
| Fire Performance | Mineral fiber core | 103 | Euroclass B-s1, d0 |
Composition and Material Layout
The core of Aerolite 103 construction is high-density expanded polystyrene (EPS), typically 100 kg/m³, sandwiched between structural facings. These facings can be fiber-cement or painted steel, selected for fire resistance and long-term dimensional stability. The laminate layers include a moisture barrier and primer to ensure strong bond integrity across panel life cycles.
Insulation Placement Strategy
Continuous exterior insulation reduces thermal bridging through structural elements, improving overall thermal performance. The 103 mm thickness is tuned to meet U-value requirements in temperate climate zones without excessive wall depth.
Fire Resistance and Compartmentation
Fire performance is a core design driver for Aerolite 103 construction, especially in medium-rise residential and commercial schemes. The mineral-filled core and non-combustible facings contribute to achieving Euroclass B-s1, d0 in standardized tests.
Fire stopping and smoke seal details should align with regional regulations, ensuring joint systems maintain integrity during fire events. Fire barriers and intumescent seals are specified at perimeter gaps and service penetrations to limit lateral spread.
Thermal and Energy Efficiency Performance
Thermal bridging is minimized by maintaining insulation continuity at corners and around openings. This approach yields consistent U-values across the building envelope, supporting energy compliance without reliance on additional interior insulation.
When combined with airtight membranes and controlled ventilation, Aerolite 103 construction supports low heating demand and stable indoor temperatures. Construction sequencing should account for vapor control layers to prevent interstitial condensation within structural elements.
Installation and Assembly Workflow
Panelized delivery and modular installation reduce on-site time and weather-related delays. Crane capacity, panel weight, and lifting profiles must be planned to match site logistics and scaffold layout.
- Verify panel coordination with structural grid and service penetrations before erection.
- Use approved fixings and edge details to maintain fire and airtightness requirements.
- Sequence wet trades to protect facings and allow proper curing of sealants and insulation adhesives.
Compliance, Testing, and Documentation
Specification of Aerolite 103 construction should reference relevant product certificates, fire test reports, and code compliance documents. Thermal modeling and on-site verification support predictive performance and commissioning checks.
Key Takeaways for Specifiers and Builders
- 103 mm continuous insulation supports robust U-values and thermal performance.
- Material selection should align with fire strategy and local building regulations.
- Detailed joint and sealing design is critical to maintain airtightness and fire compartment integrity.
- Panelized logistics can shorten schedules and improve quality control versus traditional masonry.
FAQ
Reader questions
Is Aerolite 103 construction suitable for high-rise residential projects?
Yes, when paired with appropriate fire stopping, smoke control, and structural connections, it is commonly used in medium-rise residential buildings to balance performance and buildability.
What maintenance is required for the facings over time?
Exterior facings typically require only periodic cleaning; periodic inspection of seals and penetrations helps ensure long-term airtightness and water resistance.
Can this system be used in roof applications with high snow loads?
Yes, provided the supporting structure is designed for the combined loads and roof panel fixing details are adapted for uplift and snow retention considerations.
How does Aerolite 103 compare to traditional brick and block masonry in terms of program speed?
Panelized Aerolite 103 construction often accelerates programme by enabling off-site fabrication and rapid erection, reducing on-site labor and wet trades compared to masonry.
