3. Apartment houses Chýně Locality construction of 32 timber-based multistoried detached and terrace houses. Turn-key delivery including groundwork, house connections, ground completion and fencing.

4. The basic version in two designs The houses have two stories with two studio apartments. The basic version is delivered with a saddle roof with a roof inclination of 38 . RD 180/38 apartment houses are offered in the basic version in two designs: 6 dwelling units: - 6 dwelling units 69,03 m2 10 dwelling units: - 4 dwelling units 35,15 m2, - 4 dwelling units 37,50 m2, - 2 dwelling units 69,03 m2

Technical parameters Ground plan size16,96 x 10, 63 m Number of above-ground stories2 Number of dwelling units6 (10) Type of roof construction purlin system 38  Construction of external wallsframework Thermal resistance for external wallsR = 4,195 m 2 K W -1 Coef. of thermal transmittance for external wallsU = 0,229W m -2 K -1 External wall fire resistanceREI 90, REW 60 External wall airbone sound insulationR w 44 dB Impact sound insulation for ceiling with coveringL´ n,w = 52 dB Airbone sound insulation for flat to flat wallsR´ w = 59 dB

9. Building Assembly

10. 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 600x390x80 firm product Xella, having increased the external wall fire resistance to REI 90

11. Increase of fire resistance for bearing external walls

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