Al Millar, President of Alpha Pro Tech, commented, “Overall, the Building Supply and Infection Control segments led the increase in sales for the second quarter of 2013. In 2012, we introduced TECHNOply™, an economy version of our synthetic roof underlayment, to capture market share in the lower end of the market. For the first six months of 2013, TECHNOply™ had three times the sales of the same period in 2012 and contributed approximately 9% of total synthetic roof underlayment sales, as compared to 3% for all of 2012. TECHNOply™ is expected to be a growth product for the Company. Sales of our newest housewrap, REX™ Wrap Fortis non-perforated breathable housewrap, are starting to gain traction. For the first six months of 2013, REX™ Wrap Fortis sales increased seven-fold over the same period of 2012 and comprised 9% of total housewrap sales. Sales of REX™ Wrap Fortis are expected to increase significantly in 2013. We will continue to introduce new products in our Building Supply segment as we see opportunities arise.”
