Science has taken huge strides in every sector, be it medicine, engineering, or law. Individuals (commoners or businessmen) have thrived with the advancements in their own perspectives, i.e., in terms of more facilities or revenues. Combat scorching temperatures with roof heat proofing. Ensure a cooler indoor environment and enhance energy efficiency. The heat proofing industry is also brimming with success and showcases a bright future.

People are accustomed to traditional methods (liquid and sheet heat proofing) that offer cost-effective and long-lasting solutions. However, with newer processes in the ranks, the selection criteria will become more complex. Individuals or companies will have to measure and analyze their financials before opting for a particular heat proofing system.

Let’s discuss some innovative additions to the roof heat proofing industry.

1. Heat Resistant Coating Using Hollow Microspheres

Fillers play an important role in improving the efficiency of heat-proofing liquid coating: Hollow low-density microspheres are mixed with the reflecting pigments for the same purpose. Some of its advantages include:

• High Values of Total Solar Reflectance (TSR)
• Acoustic Insulation
• Better Leveling
• Reflect Radiation (in the Near Infra-Red Region)

Microspheres are used with different compounds for improved outcomes. For example, they are mixed with titanium dioxide (TiO2) for high reflectance, and with altered colloidal silica to improve dirt pick-up resistance (DPUR). The refractive index of the bubbles (microspheres) is 1.0 while the binder has an index of 1.5: This difference is the main cause of high reflectivity.

2. IR Heat Resistant Coatings

One of the most innovative coatings formulated with special chemicals that reflect IR (infra-red radiation) back into the atmosphere. The total solar reflectance (TSR) is greatly enhanced and the heat absorption is reduced. Heat Reflective IR Coatings do not have ceramic spheres.

Some of its benefits are:

• Lower exterior temperatures by 50 degrees
• Ensures load and carbon reductions
• Reduces the heat island effect
• Prevents color fading
• Resists mold and mildew growth

3. Light-Colored Roof Heat Proofing Materials

These materials are categorized by NIR reflectance and high thermal emittance. To attain high reflectance, they are covered with light-colored pigments like white or titanium dioxide. These materials are applied on flat or low-sloped roofs for better viewing. Most common products are coatings, built-up roofs, membranes, tiles, asphalt shingles, metal roofs, and more.

4. Green Roofs

Traditionally, vegetation-based roofs are known for their capability to provide thermal insulation in cold climates and control overheating in warm climates. A typical green roof consists of:

• Structural layers (substrate and filter fabric)
• Drainage layer
• Protection layer
• Waterproofing
• Moisture barrier
• Insulation
• Separation layer
• Soil-mixture layer
• Vegetation layer or Canopy layer

Every component of the green roof is essential: The canopy offers shade, the drainage system keeps away excess moisture from accumulating, and the soil-mixture layer helps grow plants of different sizes. Some people also grow trees on the rooftops.
