Timber frame restoration

Light clay block 3DF 900

Light form-pressed adobe brick with finger hole for trusses made of especially wide (deep) beams. As mortar, loam masonry mortar is easily suitable, for plastering lime base coat hair coarse.

Field of application
Mould-made and extruded clay blocks of application class Ia for facing and non-load-bearing interior walls. Ideal for timber-frame infills with subsequent lime exterior plaster. 900 2DF for large infills and inner layers, 900 3DF with grip hole for timber frames of very
broad (deep) beams.

Composition
Building clay, wood and straw chaff.

Building material class B2 in each case; better classification is possible subject to fire protection tests (Lehmbau Regeln DVL 2009, p. 97).

Supply form
Shrink-wrapped on pallets, NF 416 units, 2DF 350 units, 3DF 240 units Breakages ≤ 4%.

Storage
Can be stored dry for an indefinite period. Up to three pallets can be stacked on top of each other.

Processing
Work with light clay blocks according to the rules of masonry. Pre-wetting the light clay blocks in the horizontal masonry joints increases the masonry’s strength. Lightweight clay masonry mortar (CLAYTEC 05.022 and 10.122) is used as masonry mortar. If lime plaster is planned, level any masonry joints; to improve plaster adhesion later on, scrape them out to create a sharp-edged recess of max. 3 mm.
