TWEHA 20two

High-performance polysiloxane sealant for glazing and façade applications

TWEHA 20-two is a high-quality, exceptionally weather-resistant and durable polysiloxane-based sealant, specially developed for professional glazing, curtain wall and façade applications.

Thanks to its permanent elastic properties and extremely high movement capability, TWEHA 20two provides a reliable and durable seal for joints exposed to movement, changing temperatures and demanding weather conditions. The sealant is easy to apply, even at low temperatures, and shows minimal stringing during application.

TWEHA 20-two is the professional choice where maximum elasticity, weather resistance and long-lasting sealing performance are essential.

TWEHA 20-two is particularly suitable for:

TWEHA 20-two is particularly suitable for movement joints in structural glazing systems, curtain walls, glazed façades and other façade constructions, as well as highly elastic movement joints in building and glazing structures. It performs equally well for perimeter sealing around façades, frames, panels, windows and prefabricated elements, and for top and heel sealing of single, insulating and safety glass. It can also be used to seal PMMA and polycarbonate sheet materials without causing stress cracking or crazing, and for the repair and renovation of damaged silicone joints in building, glazing and façade applications.
