In its latest announcement to customers, Polyglass said it is discontinuing its Polyflex SA Base underlayment product.

According to an email from Polyglass, the product will no longer be available due to the high demand for its more popular underlayment offerings. The company will work with customers to switch out existing orders that cannot be filled with the current Polyflex SA Base inventory with other self-adhered base sheets, such as its Elastobase SA self-adhered elastomeric base ply low-slope roofing product.

Earlier this year, Polyglass announced it will discontinue its Polystick MU-X and Polystick IR-Xe, stating it wishes to meet the demand for its other underlayment products.
