What is Hydroponics?
Soil-Free Plant Growing
Hydroponics is growing plants in a water-based, nutrient-rich solution. The root system is supported using an inert medium such as Rockwool. 6 basic system types:
Wick
Passive, simple
Water Culture
Roots in solution
Ebb & Flow
Flood & drain
Drip
Recovery / non-recovery
N.F.T.
Nutrient Film
Aeroponic
Root mist system
Why Rockwool for Hydroponics?
✓ Inert — does not interfere with nutrient solution
✓ Sterile — no harmful bacteria or fungi
✓ Excellent water retention and air porosity balance
✓ Supports root systems across all 6 hydroponic types
✓ Aerothane offers custom sizes not available elsewhere
✓ Competitive pricing — South Africa's largest importer

Spray & Pour Systems
Spray Foam & Hand Pour Systems
Two-component polyurethane spray foam and hand-pour systems for roofs, slabs, wall cavities and more.
32–380 kg/m³Spray ApplicationHand Pour
How It Works
Application Methods
01
Two-Component System
Components meet at the spray gun tip, reacting to form expanding foam that bonds to the substrate instantly.
02
Spray Application
Foam sprayed directly onto roof tiles, concrete slabs, wall cavities — or through holes drilled into a finished cavity wall.
03
Hand Pour Method
Components mixed and applied by hand — no spray gun required. Ideal for smaller applications and DIY.
04
Cures In Place
Foam expands, fills all voids and cures to a rigid closed-cell structure creating a seamless barrier.
Benefits
What Spray Foam Delivers
Thermal Performance
Closed-cell spray foam has one of the highest R-values per inch. Fills all gaps and voids seamlessly — no cold bridging, no gaps around fixings.
Moisture & Mould Barrier
The closed-cell structure completely seals against water ingress. Eliminates the moisture that leads to mould and mildew — especially important in coastal South Africa.
Sound Barrier
Acts as a sound barrier to excessive noise. Widely used in residential and commercial noise control — especially in wall cavities between living spaces.
Structural Reinforcement
Rigid closed-cell foam adds structural rigidity to roofs and wall panels. Spray foam roof coatings can waterproof and insulate in a single application.
