Insulated Siding Background

Insulated siding is vinyl siding with rigid foam insulation that is laminated or permanently attached to the panel. The most commonly used insulation is expanded polystyrene (EPS). 

The first field tests on insulated siding occurred in the early 1990s in the southern United States. In the years following, the product was developed through improvements in both the design and manufacturing processes to increase the product’s functionality and durability. The first commercial insulated siding was introduced in 1997. 

Over the past decade, product developments have allowed insulated siding to experience consistent growth and recognition as home insulation.
