Intermediate rafter clamping felt with optimum clamping effect
The ISOVER IntZegra ZKF 1-035 between-rafter clamping felt made of glass wool is ideal for almost cut-free insulation from the inside between the rafters in stud frames. The tried and tested line marking as a cutting aid, as well as the fine fibre structure of the clamping felt, make processing safe and fast. Compared to the thermal conductivity group 040, WLG 035 improves thermal insulation by 14%. The combination of intermediate rafter insulation and below-rafter insulation with Integra UKF-035 can also increase the energy-saving effect by up to 30%. Here, the Integra UKF-035 under-rafter clamping felt is the perfect team partner for the Integra between-rafter clamping felt.
