BUTYLVER

BUTYLVER products are high-quality, single-component, solvent-free polyisobutylene-based sealants for internal insulation (first barrier) of double or triple IG units. They feature minimal permeability to water vapor and gases, high resistance to UV aging, excellent adhesion to glass, aluminum, galvanized steel, and stainless steel.

They come in different colors to facilitate structural matching.

Using the BUTYLVER range of products in an insulating glass unit provides a high level of moisture vapor migration resistance, and controls and minimizes gas and solvent migration into the IG unit’s sealed space. It also acts as a permanent hermetic barrier to the permeation of inert gases (for example, argon) when gases are used in the sealed space of the IG unit.

BUTYLVER is designed to fill the space between the sides of the spacer and the faces of the two or three glass panes, and to develop adequate adhesion to the surfaces of both. It has movement capability so as not to fail due to limited differential movement that may occur between the spacer and the glass light.

Thanks to these features BUTYLVER contributes to limiting the formation of internal condensation achieving a longer lifetime of the window system, to increasing thermal performance of the window and energy efficiency in any season.
