Light clay block 2DF 700
Art.-Nr.: 07.013
Lightweight, form-pressed clay block of application class Ia, approved for use as infill masonry in timber-frame structures. Its composition and manufacturing process make the lightweight clay block 2DF 700 highly resistant to moisture and frost. Thanks to its good thermal insulation properties, it is also suitable for interior insulation in the form of masonry wall linings. Lightweight clay masonry mortar is used for laying the blocks. Coarse lime base plaster with hair reinforcement is suitable for exterior plastering, while clay undercoat plaster with straw is recommended for interior plastering.
