Cedrinho
( Erisma Uncinatum )
APPEARANCE : heartwood and sapwood distinguished by color, reddish brown heartwood,
imperceptible smell and taste; low density; medium-large consistency
– Durability: cedar wood has a low resistance to attacks by xylophagous organisms (fungi and
insects) heartwood and sapwood are moderately easy to preserve in pressurization processes.
– Workability: cedar wood is easy to plan, saw and sand, but has a modest finish
– Drying: air drying is simple and without significant defects. Even oven drying is rapid, but
under very drastic conditions deformation, cracking and surface hardening can occur

USEFUL INFO’S :
Despite having a low natural resistance to termite attack, after chemical
treatment and use of sealants, waterproofing and paint, it can last for many
years, requiring only sporadic maintenance. Therefore, this wood is used in
construction in general.
used in fact for doors, shutters and frames. In the internal structural part, with
slats. It is still widely used in paneling, moldings, trimmings and coatings. It is
also temporarily used for scaffolding
. In the furniture sector, it has a generic utility: in standard furniture and interior
parts of decorative furniture.
It is an excellent ceiling covering, especially in dry areas of the home. It can be
installed in living rooms and balconies, adding charm to the environment and
contributing to the decoration of the home! Cedar wood ceilings are perfect for
homes, businesses and general decorations and feature a premium finish!
