Kā ietaupīt enerģiju, izmantojot jumtus – ieteikumi jumtu renovācijai

  1. 1. Time to save energy by PITCHED ROOF with KNAUF INSULATIONRiga08.11.2012r Heat loss in the houseRoof is like : Cup during winter 25 – 30 % Hat during summer We may lose even 30% heat through wrongly insulated roof 07/11/2012 2 1
  2. 2. Pitched Roof Thermal Insulation 07/11/2012 3 Pitched Roof Thermal InsulationIn the case of usable attic we can install the insulation in the following ways:•between the rafters•between and under the rafters – KI PITCHED ROOF SYSTEMS•above the raftersThe thickness of thermal insulation and its placement depends on: • required thermal insulation performance, • roof pitch, • rafter height, • type of roof cladding used, • type of roof membrane used. 07/11/2012 4 2
  3. 3. Two layers Pitched Roof KI Systems 07/11/2012 5 Where put vapour barrier ?A / Pitched roof ridge sectional view, with vapour barrierinstalled between two thermal insulation layers. The ratio B / Pitched roof ridge sectional view with vapour barrierof the insulation between the rafters (above the vapour installed under the thermal insulation layersbarrier) to the insulation under the rafters (below thevapour barrier) should be 5:1. Recommended arrangement for KI ROOFS 07/11/2012 6 3
  4. 4. kind of vapour barrier vapor permeability equivalent diffusion [g/m2/24h] thickness of air layer Sd [m] Vapor barrier < 0,01 100 – 1000 (with metal or bitumen) Vapor retarder 0,2- 0,5 20 – 60 (PE foil thickness 0,15 – 0,2 mm) Vapor regulator 4 -700 0,1 -10 (carrier from PP fiber) 07/11/2012 7 Can GMW be installed at the entire height of the rafters?In the case of using the highly water vapourpermeable roof membrane - the thermal insulationin form of the GMW with Ecose Technology canbe installed at the entire height of the rafter.When full hard boarding or low permeable roofmembrane is installed over the thermal insulationof the GMW with Ecose Technology then aventilation gap of ca. 2.5 cm must be left under theboarding. 07/11/2012 8 4

  11. 11.

  12. 12. KI ROOF Fire Safety The ECOSE Technology mineral wool features the highest fire reaction class A1 – which means that the pitched roof products are NON-COMBUSTIBLE The requirements regarding fire reaction class contained in the Construction Law The EI 30 fire resistance class is already provided by installation of the GKF plasterboard (e.g. Knauf) of 12.5 mm thickness, on the inside surface of the roof The EI 60 fire resistance class is already provided by installation of the GKF plasterboard (e.g. Knauf) of 25 mm thickness, or fire-resistant board 18+15 mm (e.g. Knauf), on the inside of the roof07/11/2012 23 PICHED ROOF SYSTEMS KI Insulations systems Insulation between the Insulation under the Knauf Insulation rafters rafters product thickness product thickness [mm] [mm] BETTER PREMIUM ROOF Classic 200 Classic / min.50 TP 115 ENERGY-SAVING Classic 200 Classic / min.100 PREMIUM ROOF TP 115 THE BEST PREMIUM PLUS ROOF Unifit 200 Unifit min. 50 ENERGY-SAVING Unifit 200 Unifit min. 100 PREMIUM PLUS ROOF07/11/2012 24 12
