Innovative Solutions for Rubber Seals and Protection in Construction
Rubber seals are essential for protection in various construction applications by preventing water intrusion, absorbing vibrations, and enabling tight connections between structural elements. The right compounds and innovative seal designs ensure long-lasting protection and reduce maintenance costs. In this article, we examine common seal types, their roles in protection, and typical use cases.
Types of Rubber Seals
EPDM and Silicone Seals
EPDM (ethylene propylene diene monomer) seals are preferred in construction due to their resistance to weather, UV, and extreme temperatures (–40°C to +120°C). They are ideal for windows, doors, facade panels, and connection joints.
Silicone seals, made from high-purity compounds, tolerate a broader temperature range (–60°C to +230°C) and are used for roofing, ventilation systems, and facades requiring long-lasting elasticity under thermal changes.
Profiled and Flat Seals
Profiled seals (D-, P-, U-shaped) precisely fit spaces between surfaces for fast installation and effective sealing. Flat seals are used as extra barriers between panels or secondary seals against leakage.
Importance of Rubber Compounds
Selecting the Right Compound
High-performance compounds with anti-wear and anti-aging additives enhance resistance to chemicals. Nitrile (NBR) rubber resists oils and is used in seals exposed to lubricants or fuel.
Vulcanization and Material Properties
During vulcanization, rubber turns elastic and durable under correct temperature and pressure. Additives ensure seals resist UV, mechanical loads, and time, remaining effective even after years in harsh building environments.
Applications in Construction
- Facade Joint Sealing: Seals prevent water/wind ingress and improve energy efficiency.
- Window and Door Sealing: Seals prevent thermal losses and noise, improving comfort.
- Roof and Finishing Seals: Seal vents and overlaps to prevent leaks using long-lasting EPDM or silicone.
- Vibration and Impact Protection: In bridges and buildings, rubber absorbs traffic/equipment vibrations to prolong structure life.
