Your choice influences the carbon footprint of construction

Inora Luonto HVAC insulation replaces traditional fossil-based oil with bio-oil — reducing the raw material’s CO₂ emissions by up to 80% compared to conventional plastics. The plant-based biomass used in the bio-oil is sourced from bio-waste supplied by contracted European partners. No palm oil or food-grade plants or plant parts are used in the production of the bio-oil. Instead, it is made from plant residues such as tops, peels, and other by-products that would otherwise go to waste.

The BMB (BioMass Balanced) raw material used for our Luonto products was developed by BASF, and Inora was among the first companies in the world to bring products made from it to the market. Be part of building a more sustainable tomorrow by choosing Inora Luonto HVAC insulation. Luonto products are 100% recyclable in standard plastic recycling.

You can find more detailed information on the BMB material of Inora Luonto products on the raw material manufacturer's website here.

Pipelines installed underground must be protected from frost. The options are to either dig the pipes to a frost-free depth or to insulate them. Insulating pipes against frost is easy using Inora Luonto HVAC insulation.

When installing closer to the ground surface, you save especially on excavation, blasting, and backfill costs. In this case, the need for trench shoring also decreases.

Things to consider when planning pipe insulation:

• Climatic factors, such as the average annual temperature, the design frost depth, and the amount of snow cover. Pay attention to areas where snow is plowed away!

• The foundation conditions of the pipelines and the effect of the soil.

• The amount of heat available from the pipeline and the permissible temperature drop in the pipelines.

• The thermal properties of the Inora HVAC insulation used.

• The external traffic load and ground pressure on the structure.

• To protect the pipes from frost, the pipe with its insulation is placed inside the bedding sand in the trench.

• In demanding conditions, the frost protection of the pipes can be improved by using Inora 120 Routa, Inora 200 Infra, or Inora 300 Infra insulation board in addition to the pipe insulation.

The pipe insulation pieces are pressed against each other at the tongue and groove, and the joint can be secured with tape or adhesive. Suitable adhesives include construction adhesives and sealants. The surfaces of the pipe insulation can be painted with latex paint or covered with a protective tape. For working with the pipe insulation, such as miter cutting for bends, a fine-toothed saw is used.

Insulating HVAC ducts is easy and convenient with the interlocking Inora Luonto HVAC duct insulation.

• The pipe insulation pieces are pressed against each other at the tongue and groove, and the joint is secured with tape or adhesive. Tongued joints are recommended to be sealed with vapor barrier tape, and cut joints with polyurethane foam.

• Suitable adhesives include construction adhesives and sealants.

• The surfaces of the pipe insulation can be painted with latex paint or covered with protective tape.

• For working with the pipe insulation, such as miter cutting for bends, a fine-toothed saw is used.

• If the insulation needs to be cut, you should use the cutting lines marked on the insulation. When using the cutting lines, note that both insulation pieces must be oriented the same way.

• In the duct system, first install the bends, connections, and branches, and then the straight sections. We recommend securing the transverse seams with duct tape.

• It is possible to support the duct insulation with a perforated band over the insulation or to install it directly on top of the ceiling supports.

• The tongued insulation can be installed on the ducts before the actual duct installation work.

• When using the insulation on cooled ducts, all seams must be sealed with vapor barrier tape.
