THE BASIC SYSTEM

1
THE BASIC SYSTEM

• Hollow expanded
  polystyrene block
• 1200mm long
• 300mm high
• 150/180mm wide
• Core filled with concrete and Y10 reinforcement.
• Finish plastered with specially developed plaster
  StyroGuard

2
ADVANTAGES AND BENEFITS

• SPEED OF CONSTRUCTION
• 3-5 times faster than brick or concrete block
• Bricklayer average 7-8m2/day
• Styrox 30-40m2/day.Faster on straight walls.

760m2 Styrox house - walls completed
in 15 working days

ADVANTAGES AND BENEFITS

• THERMAL INSULATION
• Expanded polystyrene acts as an insulating
  material. (Igloo effect)
• Thermal insulation compared to other materials
• - 400 vs cement blocks
• - 60-70 vs solid brick wall
• - 40-50 vs cavity brick wall
• Gives better living environment and reduces
  energy costs

• SINGLE BRICK WALL PLASTERED 3,90
• 190MM CEMENT BLOCK PLASTERED 5,90
• ½ BRICK WALL PLASTERED 9,10
• 140MM CEMENT BLOCK PLASTERED 10,00

6
ADVANTAGES AND BENEFITS

• STRUCTURAL INTEGRITY
• Provides continuous reinforced concrete structure
  in a permanent formwork
• 2,5 times as strong as equivalent brick wall.
  (Infill mix 15MPa develops to 20MPa)
• This provides added security and reduced
  maintenance costs

7
ADVANTAGES AND BENEFITS

• EASE OF BUILDING
• Do not need a lot of skilled artisans
• Easy to train unskilled labour to use system
• Ideal for woman
• No need for lintels over openings
• Blocks can be cut to size with hand saw
• Services either run in cavities or by cutting
  polystyrene with carpet saw

8
ADVANTAGES AND BENEFITS

• WEIGHT REDUCTION
• 50 lighter than solid or cavity brick wall
• Allows reduction in structural support/foundations
  
• Can make even lighter with lightweight infill
  concrete

9
ADVANTAGES AND BENEFITS

• WATER/DAMP RESISTANCE
• The Styrox block is impervious to water.
• StyroGuard plaster contains an acrylic polymer
  which itself resists water.
• Improves living conditions in coastal and wet
  environments.

10
ADVANTAGES AND BENEFITS

• INTERNATIONALLY ACCEPTED
• Expanded polystyrene is a standard building
  material in Europe, Asia/Pacific and the USA
  because of the advantages listed and the high
  cost of labour in these markets. Brick is seldom
  used.

11

• INTERNATIONALLY ACCEPTED
• 15 of residential construction in the US now
  from LCFs/ICFs (lightweight concrete forms
  /insulated concrete forms)
• This method of construction has doubled every
  year since 1997
• Most popular method timber frame with
  prefabricated insulated panels

12
ADVANTAGES AND BENEFITS

• AGREMENT CERTIFIED AND NHBRC APPROVED
• Styrox has been in South Africa for 10 years
• and received Agrement certification and NHBRC
  approval

13
ADVANTAGES AND BENEFITS

• Agrément SA Certificate No. 98/267
• This certification clears way for banks to
  provide bond finance

THE FUTURE

• Energy efficient legislation 2008/2009 effecting
  new homes.
• Power shortages.
• Brick and labour shortages.
• Housing backlog
• NHBRC rapid build and innovative home design
  competitions.
• Government drive to introduce alternative
  technologies.
• Increased use of expanded polystyrene in
  buildings wall systems, slab systems, cornices
  and wall mouldings, insulated ceilings, insulated
  roofing.
