Why Finnshield ?
Lower electric bills and protect environment
In Nordic countries, electricity is generally affordable. However, prices tend to surge during peak hours, typically in the daytime on working days. By strategically avoiding these peak hours and utilizing heat accumulators, electric heating has the potential to be significantly more cost-effective compared to alternatives like district heating.
FinnShield’s energy storage system operates by loading the accumulator during periods of low electricity prices. The accumulator, designed to store thermal energy, efficiently captures and retains the heat or coolness. At peak hours, when electricity prices are typically higher, FinnShield utilizes the stored energy to transfer heat or coolness to the room as needed.
This approach allows for the optimization of energy consumption by utilizing electricity during off-peak hours when prices are lower, effectively reducing costs. Additionally, it helps alleviate the strain on the electrical grid during peak demand periods while ensuring a comfortable indoor environment for occupants.
Wood stands out as an excellent material for thermal accumulation. It can retain nearly as much thermal energy per unit volume as brick, yet exerts less than half the load on foundations. The Finnshield wall systems are made from wood particles sourced from sawmill by-products or, in some cases, high-quality recycled wood that would otherwise be used for energy by burning, leading to the emission of approximately 1.8 kg of CO2 per kilogram of wood.
Within Finnshield walls, this precious biomass, in the form of carbon, is sequestered for decades.
Wood has traditionally been less utilized as a thermal mass material, primarily due to its insulating properties. However, at Finnshield, we’ve successfully addressed this issue to get energy in and out from wooden accumulators.

Meeting future EU regulations
The EU is in the process of formulating a new directive, under which all older buildings currently classified in energy class G must undergo renovations to achieve class F status by the year 2030, and then further elevate to class E by 2033. This presents a substantial challenge for Finland, where approximately 30% of single-family and townhouses fall within classes F and E. Notably, these house types predominantly rely on electric heating. Merely increasing insulation on the walls may not be the optimal solution. Instead, we should scrutinize the emission class associated with their electricity source.
During off-peak hours, electricity derives from non-combustion sources such as wind, hydro, and nuclear, boasting an impressively low emission level of 30 g/kWh. However, in peak hours, emissions surge to 10 to 20 times that figure, primarily from wood (raw material) burning units. Intriguingly, the cost differential for consumers remains relatively consistent.
The key to resolving this lies in the strategic storage of heat energy during off-peak periods, which can then be judiciously utilized during peak hours.
