Mastic Structure® Home Insulation System™

Structure® Home Insulation System™ is an exclusive combination of vinyl siding technologies and high-performance foam that wraps the home in a continuous blanket of insulation that improves thermal performance and impact resistance.

Double 4.5" Dutch Lap - Dutch Lap panels overlap each other with a shiplap joint and have a unique flat face and cove that creates a narrower reveal line, adding lots of visual interest. The decorative groove improves strength and creates deeper shadow lines.

Double 4" - Traditional Double 4" lap siding gives the historic look of wood clapboard siding, and creates a realistic shadow line where the panels appear to overlap. It is often used for a more traditional look.

Double 6" - Larger Double 6" lap siding provides a broader siding panel appearance than common profiles, and more closely re-creates the historical look of real wood siding.

Single 7" - Single 7" lap siding replicates the look of authentic overlapping wood plank siding, and offers the classic cedar dimensions and texture of wide 7-inch panels. Fiber cement is often compared to this panel, but Single 7" lap siding offers much deeper and more realistic shadow lines.
