Dry Lining Products
Plasterboard is basically an inner layer of gypsum sandwiched between two outer layers of lining paper including various additives in the gypsum layer and varying the weight and strength of the lining paper, will give the finished board different properties.
Most common plasterboards come with the option of either tapered edge or square edge. Tapered edge boards are ideal for either jointing or skimming, while square edge is generally used for textured finishes.
Most standard plasterboard has one ivory face and one brown. The liner on the ivory face is specially designed for plastering plaster should not be applied to the brown reverse face. Paper liners are generally made from recycled paper a big plus for the environment.
