Key Data Set Information
Location	NO
Geographical representativeness description	Nordics, scenarios in LCA have been calculated based on use in Norway.
Reference year	2025
Name	Hunton Nativo® Wood Fibre Blown-In Insulation
Use advice for data set	The entire lifecycle (A1-C4) is included in the analysis on which this documentation is based. Module D has also been included outside the lifecycle with energy and material substitution from recycling, and is elaborated upon under the scenarios.
Technical purpose of product or process	Hunton Nativo® Wood Fiber Insulation Blown-In is manufactured by defibrating wood chips and adding fire-retardant additives. It is used for thermal insulation of walls, roofs, and ceilings in buildings. The insulation also offers excellent sound absorption. Blown-in insulation is a time-efficient and cost-effective solution. It fills tightly around penetrations and results in zero waste on the construction site. The material is homogenous and will not vary with size. The LCA calculations are done based on a density of 33,5 kg/m3.
Classification	Class name : Hierarchy level EPDNorge: Construction / Insulation
General comment on data set	Data quality: Specific data for the product composition are provided by the manufacturer. The data represent the production of the declared product and were collected for EPD development in the year of study. Background data is based on EPDs according to EN 15804 and different LCA databases. The data quality of the raw materials in A1 is presented in the table below. Data for the production of wood fibre insulation is based on year of production in 2024. All energy consumption in database figures are assumed not used as raw material. Allocation: The allocation is made in accordance with the provisions of EN 15804+A2. Incoming energy and water and waste production in-house is allocated equally among all products through mass allocation. Effects of primary production of recycled materials is allocated to the main product in which the material was used. The recycling process and transportation of the material is allocated to this analysis. Cut-off criteria: All major raw materials and all the essential energy is included. The production processes for raw materials and energy flows with very small amounts (less than 1%) are not included. These cut-off criteria do not apply for hazardous materials and substances.

¹This impact category deals mainly with the eventual impact of low dose ionizing radiation on human health of the nuclear fuel cycle. It does not consider effects due to possible nuclear accidents, occupational exposure nor due to radioactive waste disposal in underground facilities. Potential ionizing radiation from the soil, from radon and from some construction materials is also not measured by this indicator.
²The results of this environmental impact indicator shall be used with care as the uncertainties on these results are high or as there is limited experiences with the indicator.
