High Waterproof Performance
Hydrophobic rock wool board is a thermal insulation material that
improves its water resistance through special processes, such as
adding hydrophobic agents. It retains the core advantages of rock
wool while offering enhanced moisture resistance and durability. Basements, as underground spaces, suffer from high humidity, poor
ventilation, and water accumulation—issues hydrophobic rock wool
panels address effectively.
Advantages
First, their strong moisture resistance (≥98% hydrophobic rate)
blocks groundwater or surface water seepage, preventing insulation
failure, wall hollowing, cracking, and corrosion of steel
components. Second, their stable thermal insulation minimizes heat
loss to soil, maintaining consistent temperatures to avoid frozen
pipes in winter and block geothermal intrusion in summer,
benefiting garages, storage, and equipment rooms. Third, they
inhibit mold by resisting moisture retention, reducing spore
pollution and safeguarding health. Fourth, as non-combustible
inorganic materials, they resist high temperatures and toxic gas
release, meeting basement fire safety standards.
A key shared benefit is easy construction—installable via
bonding/anchoring on concrete/brick—and durability. Core properties
persist without frequent replacement, lowering maintenance costs
and boosting cost-effectiveness.
Applications
In basement applications, they serve wall insulation: external
installation pairs with waterproof membranes for dual protection,
while internal use acts as moisture-resistant insulation for
residences and commercial garages. For floors, they are laid before
concrete pouring to prevent dampness and heat loss, suitable for
converted gyms or studios. In equipment rooms, they stabilize
temperatures on walls/ceilings, reducing malfunctions.
Practical cellar uses include full-space wine cellar insulation
(walls/ceilings/floors with moisture-proof boards) for sealed,
temperature-controlled storage. In food cellars, they reduce
external impacts to prevent mold and extend shelf life. For
collections, they stabilize conditions and resist fire/moisture,
complementing ventilation systems.
