Do You Know that Not All MMC Systems are Equal!
Welcome to the Dynamic Build Group’s free guide on Modern Methods of Construction (MMC) guide. SIPs (Structural Insulated Panels) and timber frame are both popular MMC systems, but they differ significantly in design, performance, and construction. Equally, SIPs from one manufacturer can be very different from those of another, even though both are the same system.
Think of a kettle across different brands, they all heat water, but the quality, energy efficiency and features can vary greatly.
When delivering a project with Modern Methods of Construction (MMC), it’s essential to understand the variations between systems and suppliers.
1. U-Values (Thermal Performance)
Different manufacturers may offer slightly different U-values for the same system. These U-values can impact the energy efficiency of the building and its compliance with building regulations.
Lower U-values typically mean better insulation, which can reduce heating and cooling costs and improve sustainability.
2. Material Quality and Sourcing
Suppliers may use different grades of materials or source from different suppliers (e.g., timber for frames or insulation for SIPs).
The quality of materials directly impacts the strength, durability, and long-term performance of the system.
3. Certification and Compliance
Not all manufacturers will have the same certifications or endorsements for their products (e.g., BBA, ISO 9001, CE marking, or specific sustainability certifications).
Certification provides assurance that the system complies with relevant building codes and standards, and that it has been tested and approved for performance.
4. Warranty Terms
Warranty lengths and conditions can vary between manufacturers. Some may offer longer or more comprehensive warranties than others.
A strong warranty can offer peace of mind, particularly in terms of repairs or replacement of faulty materials or systems over time.
5. Insulation and Performance Options
For systems like SIPs, the type and thickness of the insulation used can vary. Some manufacturers may offer alternative types of insulation (e.g., expanded polystyrene, polyisocyanurate, or mineral wool).
Different insulation materials have varying levels of thermal resistance, environmental impact, and costs. The choice affects the building’s energy efficiency and its compliance with sustainability goals.
6. System Assembly and Installation Techniques
The methods or level of support provided for system assembly and installation can vary. Some manufacturers may offer a fully integrated service, while others may provide kits for on-site assembly.
The ease and speed of assembly can impact construction time and costs. A more streamlined installation process can reduce labour costs and minimise project delays.
7. Fire Performance
Some manufacturers may offer additional fire-resistant treatments or materials to improve the system’s fire rating.
Fire performance is critical for building safety and for meeting building regulations, particularly in residential, educational, or commercial developments.
8. Environmental Impact and Sustainability
Some suppliers may offer more environmentally friendly or sustainable solutions, such as using recycled materials, low-impact manufacturing processes, or offering carbon offset options.
Many developers, self-builders, and architects are looking to meet sustainability goals, and manufacturers offering greener solutions may be preferred.
9. Cost and Value
Prices can vary depending on factors like material quality, system complexity, and added services (e.g., delivery, installation).
Budget considerations are critical for developers and self-builders, and a lower-priced system may not always deliver the best long-term value if it has higher ongoing maintenance costs.
10. Delivery and Lead Times
Lead times can vary from one supplier to another, with some manufacturers offering faster delivery or providing prefabricated units ready for immediate assembly.
Delays in delivery can slow down project timelines and increase costs. Suppliers with shorter lead times may be preferred for projects with tight schedules.
Conclusion
Choosing the right MMC system and manufacturer is crucial for the success of your project. Whether it’s performance, cost, flexibility, sustainability or accreditations the variations between suppliers can have a big impact.
At Dynamic Build Group, we help you navigate these choices and offer expert training through our academy or delivery and construction services.
