Abstract: The glass fiber mesh-rein orced composite insulation wallboard was conducted with bending and compression prop-
erties exper mental studies, and its deformation and damage characteristics and ultimate flexural, compressive bearing capacity were
obtained; In addition, wallboard insulation properties were tested. Studies have shown that: thermal insulation properties of the wall
board were in line with GB 50176-93code for thermal design of civil building, wallboard has good mechanical properties in the
lateral bending and axial load effect, compared to the wallboard with and without fiber mesh, average ultimate load of wallboard in-
creased 14.98%, and the mean value of greatest moment suffered by the middle of span improved 8.06%, the compressive strength
of wallboard was 4. 29 Mpa, in line with the compressive strength requirements of non-load-bearing wallboard as specified in stan-
dard G/T 169-2005light board for building partition wall".
