Description

135mm Knauf Ceiling Insulation Roll

135mm Knauf is a glasswool ceiling insulation commonly used in homes and buildings. Manufactured using ECOSE Technology, it provides both thermal and acoustic performance, while the thicker 135mm profile makes it well suited to projects where higher thermal resistance is required from a single layer. Its lightweight, flexible construction also makes it practical to handle, cut and fit during professional installation.

Supply & Installation of Knauf 135mm

Home Insulations supplies and professionally installs Knauf 135mm for insulation projects where a higher level of thermal performance is required. We can help confirm whether the 135mm thickness is suitable and calculate the approximate quantity needed from the area to be insulated.
