Wallrock Thermal | Cosy Liner R300 | 100cm x 25m
Wallrock Thermal Cosy Liner R300 100cm Width 25m Length 300gsm (approximately 1mm thick) (25m2).
We're always asked what is the difference between R300 and KV300? They are in fact the same fantastic Thermal Cosy Liner product but just in different widths and lengths. Wallrock R300 comes in an extra width of 100cm and longer length of 25m which makes it quicker and easier to apply, and leaves less visible joins, giving a cleaner, tidier finish.
Wallrock Cosy Liner R300 is the ultimate Wallrock liner consisting of a layer of fibreliner permanently bonded to a 1mm thick textile blanket to soak up surface imperfections where a conventional liner would have no chance. Not only that, the textile reinforcement means the liner is many times stronger so that it will resist tearing and provide real worthwhile reinforcement to walls and ceilings, stopping the reappearance of cracks. The thickness and soft backing makes it a perfect candidate for covering rough walls, allowing you to cover areas that would otherwise show through a standard lining paper.
