## 1. What are SIPs and how do they work?
SIPs (Structural Insulated Panels) are high-performance building components consisting of a solid insulating foam core sandwiched between two structural boards (OSB or fiber cement). Sips Modular Homes uses only Fibre Cement Board. They create a complete wall & floor, system that is both load-bearing and thermally efficient.
## 2. How much does building with SIPs cost?
While SIPs materials may cost 3-5% more than traditional timber framing, total project costs are typically lower overall due to reduced labor, faster construction timelines, and minimal on-site waste.
## 3. Are SIPs homes more energy efficient?
Yes. SIPs create a nearly airtight building envelope, reducing heating and cooling costs by 30–60% compared to conventional construction methods.
## 4. How much faster is construction with SIPs?
On-site installation of a SIPs structural shell typically takes 6–18 weeks, compared to 12+ months for traditional builds—making SIPs significantly faster.
## 5. Are SIPs fire-rated and BAL compliant?
SIPs can be engineered to meet specific fire-resistance ratings and BAL (Bushfire Attack Level) requirements, making them suitable for bushfire-prone areas with proper specifications.
## 6. Do SIPs homes look different from regular homes?
No. SIPs are highly versatile and can be finished with any standard cladding—brick, timber, render, or modern materials—creating homes indistinguishable from traditional construction.
## 7. What are the common negatives or risks of SIPs?
The primary consideration is moisture management. When installed with proper sealing and ventilation protocols, SIPs are durable and long-lasting. Correct installation prevents potential moisture-related issues. Sips Modular Homes provide a spray on moisture sealant for both internal & external walls with every home pack.
## 8. Can SIPs be used for custom home designs?
Absolutely. Modern SIPs are precision-cut to match bespoke architectural designs, offering greater design freedom than many traditional building methods.
## 9. Are SIPs resistant to termites and pests?
Yes. Most SIPs panels are treated for termite resistance, and some use naturally resistant materials (like fiber cement) that provide additional protection against pest damage.
## 10. How long do homes built with SIPs last?
High-quality SIPs homes are designed to last 50–70 years or more when installed correctly with proper maintenance.
