OSB roofing is a very popular choice in residential and light commercial construction. The material is more dimensionally stable than plywood and very consistent from one piece to the next. OSB laminated to EPS is called nail base and is commonly used for log cabin roofing and other roofing applications. SIP Panels are constructed using two layers of OSB with EPS between. These panels are used for exterior walls and rooves. Call us today to ask your question about OSB or SIPS panels.
