Our quest to explore efficiency led to investigations into ways in which we could improve the energy efficiency of Stand 47 while also incorporating our aim to demonstrate the potential of innovatively using Saint-Gobain products in a typical residential home. It soon became clear that Saint-Gobain’s insulation products would form an important part of this exploration of both efficiency and innovation. A number of options were chosen during specification in Step 3, and here we will look at the insulation products chosen and why.
Isover cavitybatt insulation
- It is used within steel frame structures, timber frame buildings and dry wall systems (51mm – 102mm). Stand 47 is using both a steel frame structure and drywalling.
- Exceptional acoustic properties
- Lightweight & easy to handle / Maintenance free / Long product life – will not readily age
- Self-supporting – will not sag when placed in drywall framework
- Compression packed – to reduce volume & optimize transport & storage
- High tear strength yet readily cut with a sharp blade
- Manufactured according to ISO 9001:2008
- Non-combustible – tested to SANS 10177 Part 5
Snap on pipe insulation
- Lifelong energy savings due to reduced head loss though pipes and increased heating cycles.
- Excellent thermal & acoustic properties
- Available in a wide range of pipe bore and insulation thickness
- Long product life / Maintenance free / Ease of installation
- Ease of fabrication – on site modifications are easy
Sagex eps perimeter insulation
Key properties of Sagex EPS that were applicable to our needs:
- Thermal Insulation to meet SANS 204 insulation (R-value = 1,05)
- Resistant to ageing, mildew, bacteria rot and will not sustain vermin
- CFC / HCFC free and zero ozone depleting potential
- Low water absorption Sagex EPS 40mm thick x 300mm wide, 15kg/m³ density from ground floor level with joints tightly butted and taped.
In addition, SANS 204:2011 stipulates that buildings with a floor area of less than 500m², with concrete slab-on-ground, shall have insulation around the vertical edge of its perimeter.
Sagex eps floor insulation
- Thermal insulation of heated ground floors (R-value = 1,14).
- Resistant to ageing, mildew, bacteria rot and will not sustain vermin
- CFC / HCFC free and is considered ozone-friendly by the Wildlife Society of South Africa.
- Life long energy savings. Excellent thermal and acoustic properties.
- Maintenance free, ease of installation and ease of fabrication – on site modifications
SANS 10400-XA:2011 require that where an underfloor heating system is installed, the heating system shall be insulated underneath the concrete slab with insulation that has a minimum R-value of not less than 1,0. Therefore, Stand 47 will install 40mm thick 20kg/m³ density Sagex EPS Floor Insulation on damp-proof membrane with joints tightly butted. Sagex has more than 50 years experience in the manufacture of EPS and introduced the product into the South African market.
Geyser insulation pack
- Lightweight & easy to handle
- DIY friendly
- Long product life-will not readily age
- Suitable for high humidity applications
SANS 204:2011 states that “hot water vessels and tanks shall be insulated to a minimum R-value of 2,0… Piping to be insulated include all flow and return piping, cold water supply piping within 1m of the connection to the heating or cooling system…”. This product achieves this requirement.
Aerolite insulation
- Lightweight & easy to install
- Exceptional thermal and acoustic properties
- Compression packed to reduce volume and optimize transport + storage
- Reduces heat loss in winter and contributes toward reduced heating costs.
- Reduces heat gain in summer and contributes toward reduced cooling costs.
- Non-combustible – tested to SANS 10177 Part 5
