The UNI-flex Ecoplug is the smart and sustainable choice for installing cavity wall insulation with a high compression strength in combination with UNI impact cavity wall ties (Ø 4 mm) in interior walls made of concrete, sand-lime brick, or solid brick. Thanks to its intelligent design, this plug uses up to 25% less material than the UNI-Flexplug. Moreover, the absence of color additives makes the UNI-flex Ecoplug fully recyclable—a conscious choice for a greener future.
