Wood-fibre insulation is an excellent insulator during the winter as well as during the summer. The usual insulators prevent the cold air from entering during the winter but that is insufficient if the protection from summer heat is required.
The main advantages of wood-fibre insulators are as follows:
- Excellent protection from cold – decreases the heating costs
- Excellent thermal protection – decreases the cooling costs
- Good sound insulation - provides peace indoors
- Natural ability to receive and emit humidity from the air – positive impact on the atmosphere indoors
- Vapour permeability (vapour diffusion-open construction) – positive impact on the atmosphere indoors
- Sufficient fire safety
- Universal usability (walls, ceilings, beams, bearers)
- Simple and harmless assembling
- The possibility of recycling
COMFORTABLE TEMPERATURE IN-DOORS – PHASE SHIFT
Good material that positively affects the indoor conditions; has low thermal conductivity and high thermal capacity i.e. it is able to accumulate heat. Both characteristics inform us about the so-called phase shift, which is the period of time necessary for the accumulated part of the heat to re-enter the interior. Wood-fibre insulators achieve up to 14 hours phase shift, which means that wood insulation provides comfortable temperature indoors during 24 hours.
ENERGY SAVINGS
The thermal permeability factor of a RIKO house outer wall with thermal insulation 12 cm thick is 0.25 W/m2K. RIKO houses belong to the low/energy class B. The thickness of the insulation layer can be enlarged thus making the heat transfer coefficient vary from 0.15 to 0.25 W/m2K. It also means that the annual fuel consumption can be reduced even more.
ENERGY CERTIFICATE
The Energy Certificate provides the basic information on thermal characteristics and we obtained it in cooperation with the Institute for Researching Materials and Constructions (ZRMK Ljubljana). RIKO houses belong to the low-energy class B.
