Description
Calder’s geotec 220PY underlay is only suited for use on existing traditional timber board substrates in conjunction with ventilation. It has been specifically designed and manufactured to prevent ridges and fractures forming in each lead sheet, where thermal movement causes it to pass over the edges of individual boards.
Extremely lightweight (weighing only 220 g/m2), it is a high-quality, durable, non-woven, needle punched, polyester textile underlay.
Available in:
- 25 m x 1000 mm roll
