With the term cool roof are identified covers characterized by a low surface temperature, even under direct solar irradiation.
ThermaShield has low thermal absorption combined with high insulating capacity, it is waterproof and resistant to the elements, made with the classic and most widespread materials (Brick – Ceramics – Bituminous sheaths – metals and plastics ).
Notoriously the Cork is a material that tends to maintain a temperature in equilibrium between 0 and 30 ° C regardless of the temperatures to which it is subjected. Suberite does not absorb and does not transmit heat by offering high waterproofing and heat insulating capacities.
There are many advantages of creating coverage treated with ThermaShield:
- Better environmental conditions in the summer period of the interior of the building
- Energy saving for summer air conditioning and winter heating of the building’s interior rooms
- Improves the energy efficiency of the entire building
- Reduction of heat island effect (with heat island is defined the phenomenon of temperature rise that is generated in urban areas compared to the temperature recorded in rural areas)
- Greater dimensional stability of the covering stratigraphy and of the underlying load-bearing structures due to the reduced influence of high summer temperatures (minor movements, expansions, cracks, etc.)
- Greater durability and life expectancy of waterproof roofing membranes, since the action of natural aging induced by heat is greatly reduced by the low surface temperature
ThermaShield coatings represent the most performing solution in terms of Reflectance, Emissivity and Heat transmitted.
SUPPORT PREPARATION

General information on Cool roof systems
Premise
Today, the main objectives of sustainable construction, with a view to respecting the environment, are to reduce global warming, reduce the emission of pollutants, reduce the effect of heat islands, thus reducing the use of energy for the air conditioning, while still keeping the conditions of the rooms comfortable during the summer.
Islands of Urban Heat
Urban heat islands are a problem of our times, typical of highly urbanized areas.
Due to solar irradiation, the roofs of buildings and the road surface heat up and reach high temperatures.
Buildings and asphalt release heat to the air, day and night.
Because of this, the air temperature remains at least 4 ÷ 5 ° C higher than in the surrounding countryside.
The high temperature accelerates the photochemical processes that generate the smog and the various pollutants that form it (+1 ° C = 5% ozone) and induces the increase in energy consumption for air conditioning (+1 ° C = 3% consumption) .
What is the Cool Roof
The Cool Roof is a cover with a high capacity to reflect the incident solar radiation and a high emissivity value in the infrared. All this allows the roof to return most of the absorbed fraction to the atmosphere, by thermal irradiation.
The Cool Roof is characterized by a low surface temperature, even under direct solar irradiation. The Cool Roof is based on the use of techniques for heat control with the use of high reflectance solar materials and high thermal emission, which have the ability to keep the roof fresh.
What is Solar Reflectance
- Solar reflectance is the property of a material to reflect solar radiation.
- A surface with high solar reflectance remains cooler, as it reflects most of the incident solar radiation.
- Light colors, especially white, have a high solar reflectance.
- The solar reflectance is expressed with a value from 0 to 1, or in%.
What is Thermal Emissivity
- Thermal Emissivity is the ability of a material to dissipate heat.
- A surface with a high thermal emissivity remains cooler because it has the ability to effectively dissipate heat to the environment.
- The MBDP polymer bitumen membranes have a high thermal emissivity.
- The emissivity is expressed with a value from 0 to 1, or in%.
What is the SRI (Solar Reflectance Index) value
SRI is the solar reflection index. It is calculated according to the ASTM Standard E1980 and considers the effect of both solar reflectance and thermal emissivity. It varies between 0% (reference black color) and 100% (reference white color) and can be greater than 100%. The higher the SRI value, the lower the surface temperature.
Advantages of the Cool Roof
There are many advantages of a Cool Roof cover:
- Improvement of the conditions of the interior of the building during the summer
- Energy saving for the summer air conditioning of the interior of the building
- Reduction of the heat island effect
- Improvement of dimensional stability of the roofing systems and underlying supporting structures (minor movements, expansion, cracks, etc.)
- Maintenance over time of the characteristics of waterproof roofing systems, thanks to low surface temperatures and lower stresses.
- Improvement of the overall energy efficiency of the building.
