Chimney construction is essential for ensuring proper ventilation and heat management in homes and industrial setups. Straight chimneys are vertically aligned, ideal for structures where direct, efficient airflow is needed. On the other hand, tapered chimneys feature a narrowing design from base to top, improving the draft and reducing the chance of backdrafts. Both types are built with durable materials, such as stainless steel, brick, or concrete, to withstand high temperatures and weather conditions. Proper construction ensures optimal performance, safety, and longevity, making it a crucial part of any heating or industrial system for smoke ventilation and heat exhaust.
