What is the R-value of Expol underfloor insulation?
EXPOL ThermaSlab (EPS – Standard Expanded Polystyrene Sheet) is a lightweight polystyrene board that does not compromise on insulation performance. At a thickness of 50mm, EXPOL ThermaSlab S delivers an R-value of 1.32 and ThermaSlab H delivers an R-Value of 1.39.
What is Expol made of?
EXPOL Tuff Pods are constructed from expanded polystyrene (EPS), a material that is 98% trapped air. The cellular structure of the polystyrene foam keeps the pods dimensionally stable for the life of the building. Polystyrene insulation board is also resistant to moisture and rot.
Can you use Expol in walls?
Resistant to moisture, EXPOL Platinum Board (Graphite Infused – Premium Expanded Polystyrene Sheet) is an excellent choice for wall cavities as it does not allow moisture to transfer from the exterior cladding to interior wall linings.
What is the highest R rating for underfloor insulation?
0 insulation to a timber floor rated R0. 7, can help achieve an overall rating of R2. 7, representing a vast improvement to the home’s thermal comfort. This is the highest R Value rating achievable with R2.
What is the best type of underfloor insulation?
Which Underfloor Insulation Is Best?
- Polyester rolls such as GreenStuf Underfloor Insulation are a type of bulk insulation.
- Glasswool batts such as Knauf Earthwool Underfloor Insulation Batts are also a type of bulk insulation which rely on billions of tiny air pockets to slow down heat flow.
What is the R value of polystyrene insulation?
Expanded polystyrene foam (EPS) is the cheapest and least used foam board product on the market. This product typically has an R value of 3.6 to 4.0 per inch of thickness.
What R-value should underfloor insulation be?
1.3
Underfloor insulation needs a minimum R-value of 1.3. * ‘R’ stands for resistance – an R-value is a measure of how well insulation resists heat flow.
Is Expol flammable?

What is a good R-value for flooring?
R-Values of Different Flooring Materials
| Material | Typical R-Value | Typical Thickness |
|---|---|---|
| Carpet Pad/ Waffle Rubber 25 lb | 0.620 to 1.240 | 0.250 to 0.500 |
| Hair Jute | 1.250 to 1.940 | 0.325 to 0.500 |

| Bonded Urethane | 1.400 to 2.100 | 0.325 to 0.500 |
What does the are value on expol insulation mean?
Welcome to the EXPOL R-Value Calculator. An R-value is a rating which measures how well insulation can resist heat flow. ‘R’ stands for thermal resistance. The R-value depends on the type of material, its density and thickness.
What is the insulation value of expol underfloor?
EXPOL UnderFloor insulation meets and exceeds the requirements of the Act. For an insulation product to provide adequate insulation to a rental property it needs to have a minimum insulation value of R1.3 – EXPOL Black insulation exceeds this with a value of R1.8.
Which is more efficient expol R1.4 white or black?
Both products deliver R Values that meet and exceed building regulations however EXPOL R1.8 BLACK is used where the environment is extreme. EXPOL R1.8 Black is 35% more efficient than EXPOL R1.4 White because it incorporates graphite in it’s manufacturing process. The obvious visual difference is R1.8 is black and R1.4 is white.
