The two-piece roller shutter box insulation is ideal for subsequently damping large roller shutter boxes, thus reducing heat losses and temperature fluctuations. The insulating mat increases the comfort of living, saves energy and thus contributes to the reduction of the heating costs. It also absorbs external noise, acts as sound insulation and protects against the ingress of dust and drafts.The set consists of a insulating wedge made of NEOPOR(r) (a BASF brand) and a 25 mm thick insulating mat made of styrofoam, NEOPOR(r) and a breathable diffusion layer. NEOPOR(r) has a better thermal insulation property with its own strength compared to Styropor. The combination of the materials results in the thermal conductivity group less than 035. The smaller the number of heat conduction groups, the better the insulation properties of the material.The insulation wedge as well as the insulation mat can be individually cut to the required size. An extension of the insulation is also possible due
