Double- and triple-glazed roof windows help meet near-zero energy building requirements. This trend is supported by government incentives for retrofitting older housing stock. Manufacturers invest in low-U-value designs and integrated ventilation systems to meet these regulations. The push for sustainable housing continues to be a strong growth catalyst for the Finland roof windows market.
- For instance, Finland requires new buildings to use glazing with U-values no higher than 1.0 W/(m²·K) for windows and external doors.
Increasing Renovation and Remodeling Activities
Renovation projects dominate Finland’s construction sector, driving consistent roof window installations. Many detached homes and summer cottages undergo upgrades to enhance natural lighting and energy performance. Skylights and roof windows are preferred solutions for adding daylight to attics and upper floors. Renovation grants and tax benefits offered by the Finnish government encourage homeowners to adopt energy-efficient solutions. Rising consumer interest in improving indoor comfort further fuels demand. This steady renovation cycle provides a reliable revenue stream for market players across the country.
- For instance, Finland offers a tax deduction for household expenses related to certain work, including energy improvements. The maximum deduction for most household work is €1,600 per person annually. However, a higher maximum deduction of €3,500 is available for expenses related to replacing an oil heating system with a more sustainable energy source. This enhanced deduction is a temporary measure set to expire after the 2027 tax year.
Growing Adoption of Smart Home Solutions
Smart home integration acts as a significant growth driver for the roof windows market. Consumers increasingly demand automated and sensor-based windows that open or close based on temperature, rain, or air quality.
