Pakistan’s scorching summers often lead to uncomfortably high indoor temperatures, prompting homeowners and businesses to seek effective solutions to keep interiors cool. One of the most efficient methods is the application of heat-proofing chemicals on roofs and walls. These chemicals act as thermal barriers, reflecting sunlight and reducing heat absorption. This blog delves into the various heat-proofing chemical options available in Pakistan, their benefits, application methods, and associated costs.
Understanding Heat-Proofing Chemicals
Heat-proofing chemicals are specialized coatings designed to reflect solar radiation and minimize heat transfer into buildings. By applying these coatings to roofs and exterior walls, interiors remain cooler, leading to enhanced comfort and reduced reliance on air conditioning systems. This not only conserves energy but also results in significant cost savings over time.
Popular Heat-Proofing Chemicals in Pakistan
Several heat-proofing solutions are available in the Pakistani market, each with unique properties and price points:
- Thermoshield
Thermoshield is a one-component elastomeric roof heat-proofing chemical known for its durability and effectiveness. It offers excellent adhesion and flexibility, making it suitable for various surfaces. - HELDER Heat Chemical
Marketed as a heat-proofing chemical rather than paint, HELDER Heat Chemical provides a protective layer against heat. It is designed to offer long-lasting thermal insulation. - Zem-30 Heat Shield
Zem-30 Heat Shield is a water-based, ready-to-use roof cooling paint incorporating nano-insulation pigments for superior reflection. It is applicable on various surfaces, including RCC, tiles, and metal sheets. - Heat Guard 1000
Heat Guard 1000 is a high heat-resistant reflective and waterproof coating designed to dissipate and reflect solar radiation. It is suitable for multiple substrates like concrete, bricks, and shaded metal roofs. - Lakhwa Chemical Services
Lakhwa Chemical Services is a leading provider of heat-proofing solutions in Pakistan. They offer advanced heat-resistant coatings tailored for different building types, ensuring long-term protection against excessive heat.
Factors Influencing Heat-Proofing Costs
The cost of applying heat-proofing chemicals in Pakistan varies based on several factors:
- Size of the Area: Larger surfaces require more material, increasing the overall cost.
- Type of Coating: Premium products with advanced features may come at a higher price point.
- Application Complexity: Surfaces with intricate designs or those requiring additional preparation can elevate labor costs.
- Labor Charges: Professional application ensures optimal results but adds to the total expense.
On average, roof heat-proofing in Pakistan can range from PKR 50,000 to PKR 200,000 or more, depending on these factors.
Benefits of Heat-Proofing
Investing in heat-proofing chemicals offers numerous advantages:
- Enhanced Comfort: Maintains cooler indoor temperatures during hot seasons.
- Energy Efficiency: Reduces the need for air conditioning, leading to lower electricity bills.
- Extended Roof Lifespan: Protects roofing materials from thermal stress, preventing cracks and deterioration.
- Environmental Impact: Decreases energy consumption, contributing to a reduced carbon footprint.
Application Process
Applying heat-proofing chemicals involves several key steps:
- Surface Preparation: Clean the roof or wall surface thoroughly to remove dirt, dust, grease, debris, and any existing coatings. Ensure that the surface is dry before applying any product. Pressure washing is often recommended for best results.
- Repair Damages: Inspect the surface for cracks, holes, or weak spots. Use a high-quality sealant or cement to repair any damages, ensuring a smooth and even application surface. This step is crucial for long-lasting protection and efficiency.
- Primer Application: Some heat-proofing chemicals require a primer coat to enhance adhesion and durability. Apply the primer evenly using a brush, roller, or spray. Allow it to dry completely before proceeding with the next step.
- Coating Application: Apply the heat-proofing chemical uniformly using high-quality brushes, rollers, or spray equipment. Depending on the product, multiple layers may be necessary for optimal performance. Ensure that each layer is allowed to dry before applying the next.
- Curing: Allow the final coating to cure as per the manufacturer’s recommendations. The curing process may take anywhere from a few hours to several days, depending on the weather conditions and product type. Avoid heavy foot traffic or exposure to water during this period to ensure the best results.
- Final Inspection and Maintenance: Once the coating is fully cured, inspect the surface for any missed spots or uneven areas. Regular maintenance, such as occasional cleaning and reapplication every few years, can help prolong the effectiveness of the heat-proofing treatment.
DIY vs. Professional Application
While some homeowners may consider a DIY approach to save costs, professional application is often recommended for the following reasons:
- Expertise: Professionals possess the knowledge to select suitable products and apply them correctly.
- Equipment: Access to specialized tools ensures even and efficient application.
- Warranty: Many service providers offer warranties, providing peace of mind regarding the durability of the application.
