B Impact sound insulation for ceiling with covering L´n, w = 52 d. B Airbone sound insulation for flat to flat walls R´ w = 59 d. B

Building Assembly

Increase of fire resistance for bearing external walls REI 60 was required for wall exposed to external heat stress Walls were lined with boards MULTIPOR 600 x 390 x 80 firm product Xella, having increased the external wall fire resistance to REI 90

Increase of fire resistance for bearing external walls

Construction time of key delivery Groundwork: 14 days l Upper timberwork: 67 days -> with a technological interval of 28 days for anhydride maturing l Total costs for construction: 7, 1 mil. CZK l
