PB 25
Cement-based, light screed and polystyrene. Cement dose 250 kg/m3.
Description:PB25 light screed from Fornaci Calce Grigolin is a lightweight cementous conglomerate, composed of hydraulic binder, lightweight aggregate (PB25 and PB30) and specific additive (colloidal foam).
On the employment fields:PB25 light screed has numerous fields of application, ranging from preparation of roof and terrace slopes to the rehabilitation of fretted metal sheet roofings, from the insulation of attics to filling excavation, foundations, gutters, etc. It is particularly suitable for the construction of surfaces suitable for subsequent installation of floor heating systems as it allows for the obtaining a good flatness of the jets carried out and a maximum uniformity of product. Moreover, it is suitable as a substrate for civil and industrial pavements.
