High-Performance Lightweight Self-Leveling Mortar with Vitrified Microspheres

K32’s vitrified glass bead honeycomb matrix reaches ultra-low density of only 400–700 kg/m³, drastically reducing structural load for loft mezzanines and old building retrofits. With thermal conductivity as low as 0.09 W/(m·K), it forms a seamless monolithic thermal barrier without gaps between traditional spliced foam boards, effectively cutting heating energy loss for underfloor heating floors and roof slope insulation layers. One pouring completes both leveling and insulation to simplify construction workflows.

The porous internal structure absorbs walking impact noise up to 15–20dB noise reduction, perfectly matching acoustic requirements of cinemas, recording studios, apartments and office buildings. It retains high compressive strength of 8–15MPa despite lightweight, resisting daily pedestrian traffic without deformation. Class A non-combustible inorganic composition eliminates fire hazards, safe for schools, hospitals and densely occupied commercial venues.

K32 supports full mechanical pumping with daily construction output over 1000 square meters, greatly lowering labor input and construction cycles. Standardized workflow: substrate cleaning + dedicated primer sealing, fixed-proportion mechanical mixing, self-level pouring plus defoaming roller treatment. Light foot traffic allowed after 24 hours, fully ready for tile/wood flooring after 48 hours. Factory pre-blended glass bead formula delivers stable batch quality, reducing material, labor and later maintenance costs for contractors and developers.
