On a contract monitored by BRECSU on behalf of the DOE, the payback period for the Client was 2.4 years. For the Environment the reduction in CO2 emissions was 90kg of CO2 per sq.m. of roof area per year.
This roof was 20,000m2 equating to 1800 tonnes of CO2 saved annually.
MPI foams have no CFC’s and an Ozone Depletion Potential of Zero. They comply with the Montreal Protocol, the Kyoto Summit & the ‘F’ Gas Regulations and are CE marked.
Sprayed and injected foams also give significant savings in transport costs and site wastage versus other systems.
Benefits of spray foam insulation include:
• Lowering energy costs while reducing your carbon footprint.
• Creates an air tight seal that also acts as a moisture barrier.
• Reduces outside pollutants such as dust and allergens.
• Significantly helps to create a comfortable indoor climate in both the home and work place.
• Easy to apply to virtually any surface, inside or out.
• Gives life of building insulation and energy saving , with no need to ever replace or top up.
• Enhances structural stability.
U value and condensation risk calculations to B.S.5250 are available
U-value (Thermal Transmittance):
• The U-value, also known as thermal transmittance, is a measure of how well a building material conducts heat. It represents the rate of heat transfer through one square meter of a structure divided by the temperature difference across the structure. The lower the U-value, the better the insulation of the material.

• U-values are commonly used to assess the thermal performance of building elements such as walls, roofs, windows, and doors. They are expressed in units of watts per square meter per degree Celsius (W/m²·°C).
• Regulations often prescribe maximum U-values for different building elements to ensure energy efficiency and thermal comfort in buildings.
Condensation Risk Calculation:
• Condensation risk is a concern in buildings because when warm, moist air comes into contact with a cold surface, the air may cool, leading to the condensation of water vapour. This can result in dampness, mould growth, and damage to building materials.
• The risk of condensation is assessed by comparing the surface temperature of a building element with the dew point temperature of the air. The dew point is the temperature at which air becomes saturated with moisture, leading to the formation of dew or condensation.
• The calculation involves determining the surface temperature of the building element using the U-value, the external and internal temperatures, and the thermal resistance of the material. If the surface temperature is close to or below the dew point, there is an increased risk of condensation.
• Condensation risk analysis is crucial in designing buildings to prevent moisture-related issues. It considers factors such as insulation thickness, ventilation, and humidity levels.
In summary, U-value assesses the thermal performance of building materials, while condensation risk calculations help in evaluating the potential for moisture-related problems. Both are essential aspects of building design and construction, particularly in the context of energy efficiency and occupant comfort.
Over the last 30 years, the insulation works carried out by MPI has saved our clients millions of pounds in heating costs and hundreds of thousands of tonnes of CO2 emissions.
An independent review of the impact of thermal insulation on global warming & the potential for further savings in Carbon Dioxide emissions was carried out. The results were reported in a document entitled “Thermal Insulation and its Role in Carbon Dioxide Reduction”
