GRANAB
manufactures subfloor systems for homes, offices, schools
and public buildings. The systems feature steel floor
girders with dampening elements for effective impact
and airborne sound insulation.
Granab subfloor systems are patented and type-approved
with respect to sound-dampening properties, dynamic
loads and strength. About 4 million m2 have been installed
in various projects. Granab's main office is in Vårgårda,
Sweden
with production facilities in both Vårgårda
and Lindköping.
If there is
uncertainty and risk concerning humidity content or
emissions form the bottom slab or subfloor construction,
air gaps under the finished floor should be ventilated
using mechanical ventilation in combination with the
fitting of a moisture barrier under the floor girders.
In its standard configuration, the height of the Granab
system is adjustable from 30–420 mm and provides
an open airflow under the girders.
The space under the floor constitutes a separate “room
unit” (sealed box) that is ventilated independently,
or in special cases, in combination with other ventilation. [Read more]
