Proper window and door sealing often gets overlooked. Yet, it's incredibly important for a comfortable, energy-efficient home. Surprisingly, those small gaps and cracks can significantly impact your home's performance. Addressing these tiny openings can lead to big improvements in comfort and energy savings.

The Science of Sealing

Understanding heat transfer is key to effective sealing. Heat naturally moves from warmer areas to cooler ones. During winter, heat escapes your home through unsealed openings. In summer, the opposite happens – heat enters.

This constant temperature battle makes your HVAC system work harder, leading to higher energy bills. Proper sealing minimizes this heat transfer. This creates a more stable, comfortable indoor environment.

Air infiltration, the unwanted flow of air in and out of your home, also contributes to energy loss. Even small gaps can let a lot of air through, impacting heating and cooling costs. Effective sealing minimizes this infiltration, creating a tighter building envelope. The result? A more energy-efficient and comfortable home.

The importance of sealing in home maintenance is growing. The door and window sealing strip market (excluding automotive) is projected to reach USD 1.37 billion by 2028. It's expected to grow at a 4.4% CAGR from 2023. Growth in construction and energy-efficient building standards are fueling this demand, particularly in the Asia-Pacific region. The broader weatherstrip seal market, including automotive, is projected to hit USD 13.14 billion by 2034. Learn more about the weatherstrip seal market
