Fully Insulated SIP Sunroom Addition

This sunroom renovation project was designed to extend year-round comfort and usability to the home. Built with a SIP floor system, the space is fully insulated from the ground up—unlike traditional sunrooms that often lack subfloor insulation. Instead of a conventional concrete foundation, we used helical piles, offering a fast, low-impact, and highly stable base that’s perfect for sensitive or tight-access areas. The result is a bright, energy-efficient space that blends seamlessly with the existing home while remaining comfortable in all seasons.
