EPS Structure Home Insulation System by Mastic


Structure Home Insulation System is made with a premium, recycled-content vinyl siding panel permanently bonded to expanded polystyrene (EPS) foam to provide superior looks and performance over traditional vinyl siding. It delivers natural beauty, significant insulation properties and increased impact resistance in a wide-style

clapboard look.


  • Structure 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.


  • Structure 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.


  • Structure 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.


  • Structure 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.
