In addition to thermal stability, silicone foam seals are highly resistant to weathering, UV radiation, and ozone. This makes them an excellent choice for outdoor applications where seals are exposed to harsh environmental conditions. For instance, in the construction industry, silicone foam seals are utilized in window frames and door seals to enhance energy efficiency by preventing air and moisture infiltration. Their ability to maintain performance over time under exposure to sunlight and varying weather conditions ensures that buildings remain airtight and insulated.
