A heat reflective coating, also known as a cool roof coating or solar reflective coating, is a type of paint or surface treatment designed to reflect sunlight and reduce heat absorption by surfaces. These coatings typically contain reflective pigments or additives that help to bounce sunlight away from the surface, thereby reducing the amount of heat transferred into the underlying structure.
Problems
1. Heat Absorption: Terrace surfaces can absorb excessive heat from sunlight, leading to discomfort for plants and occupants.
2.
Increased Energy Costs: Heat absorption can result in higher cooling costs for indoor spaces beneath the terrace.
3. UV Damage: Intense sunlight can cause UV damage to waterproofing materials, reducing their lifespan.
Causes
1. Poorly sealed foundation walls or floors Sun Exposure: Prolonged exposure to sunlight causes terrace surfaces to absorb heat.
2. Poor Insulation: Inadequate insulation allows heat to penetrate indoor spaces, increasing energy consumption.
3. Lack of UV Protection: Absence of UV protection leaves waterproofing materials vulnerable to degradation.
Solutions
1.Exterior Waterproofing: Apply a waterproofing membrane or coating to the exterior surface of foundation walls to prevent water penetration.
2.Interior Sealants: Seal cracks and gaps in foundation walls and floors using waterproof sealants or injection methods to prevent water intrusion.
3.Interior Drainage Systems: Install interior drainage systems, such as French drains or sump pumps, to collect and divert water away from the interior space.
4.Moisture Barriers: Apply moisture-resistant barriers, such as vapor barriers or waterproofing paints, to interior surfaces to prevent moisture infiltration.
5.Ventilation: Improve ventilation in basements and crawl spaces to reduce humidity levels and prevent condensation buildup.
