Thermoplastic (TPE/PVC) door and window wicks are modern sealing elements developed to provide high heat, sound and water insulation in structures. Thanks to their high flexibility and wide operating temperature range, these wicks, which do not harden, crack or deform over time, effectively prevent wind breezes, dust passage and external noise. Offering excellent resistance to UV rays, ozone and harsh weather conditions, thermoplastic PVC wicks offer an environmentally friendly insulation solution that increases energy efficiency in buildings with its easy application to profile channels, long service life and recyclable structure.
