What is the difference between Regular Kerfkore and single sided Kerfkore?
The two products have the same characteristics. The Regular Kerfkore has a back composed of a phenolic impregnated sheet. This enables the product to be handled as a semi-rigid sheet. The use of a scoring tool will remove the backing paper to allow the product to be as flexible as single sided Kerfkore. This can allow you have a flexible panel where needed and a rigid section when preferred.
