While SIPs offer numerous advantages, there are some downsides to consider: 1. Higher Initial Cost: The upfront cost of SIPs can be higher than traditional framing methods. 2. Specialized Installation: Proper installation of SIPs is crucial for optimal performance, which may require hiring experienced professionals. 3. Limited Availability: Depending on your location, some SIPs may not be readily available, leading to higher shipping costs and longer lead times.
