Staļi SIA

For over 30 years, SIA “Staļi” has been a full-cycle manufacturing company, crafting premium wooden and wood-aluminum windows and doors from locally grown Latvian timber. The company manages the complete processing of roundwood—from the production of wood boards and laminated timber beams to the final product—while manufacturing byproducts are efficiently utilized to produce premium quality wood pellets.

Combining exceptional design, energy efficiency, and sustainability, we offer solutions for private projects as well as for architects, builders, and developers—ranging from proven classics to custom, highly complex orders. SIA “Staļi” continuously evolves, introduces innovations, and expands its product range, proving that top-tier wooden windows and doors are more accessible than traditionally thought.

The high quality of our products and our responsible use of forest resources are validated by internationally recognized certificates: P-mark (RISE), NDVK, ISPM HT, as well as ENplus (for wood pellets) and the FSC Chain of Custody certification.

The high quality of our products is validated by internationally recognized certifications: P-mark (RISE Research Institutes of Sweden), NDVK (Norsk Dør- og Vinduskontroll), ISPM HT (International Standards for Phytosanitary Measures), and the EPD (Environmental Product Declaration). Additionally, our wood pellets hold the ENplus® certification, and our operations are backed by the FSC® Chain of Custody certification, which confirms our commitment to the responsible and sustainable use of forest resources.

We operate with strict environmental responsibility, choosing sustainable solutions and meticulously selecting raw materials. This dedication allows us to create energy-efficient products that are built to last, maintaining their premium quality for decades.

In the production of wooden windows and doors, we use only proven materials that ensure the premium quality of the final product. SIA „Staļi” equips its windows and doors with hardware supplied by the world’s leading brands in the industry—including Fix, ASSA, Roto, Spilka, Centor, and others.

Continuous quality control implemented throughout the entire production cycle allows the company to guarantee the highest standards for both products and services. Our windows, doors, and other products are tested in our own certified in-house laboratory, as well as sent to leading testing institutes across Europe to ensure full compliance with international standards and flawless functionality.

Forests cover approximately 54% of Latvia’s territory. Wood is a renewable yet precious natural resource with a wide spectrum of applications. By acting with environmental responsibility and focusing not only on harvesting but also on reforestation, we ensure the long-term availability of this resource while preserving biodiversity.

Thoughtful, sustainable, and eco-friendly manufacturing is a core priority for SIA “Staļi”. Our specialists carefully evaluate all timber supply partners. Alongside material quality, minimizing transportation distances is crucial to us, as it reduces vehicle utilization and lowers harmful transport emissions.

Decades of experience in woodworking have allowed us to refine and successfully develop high-quality manufacturing, delivering only the finest premium wooden windows, doors, designer homes, and pellets.

Even manufacturing byproducts, such as wood shavings and sawdust, are collected and utilized with maximum efficiency. Furthermore, SIA “Staļi” wooden windows, doors, and designer homes are easily restorable and can be eco-friendly disposed of at the end of their lifespan.

Only high-quality windows and doors crafted by professionals can guarantee excellent thermal insulation and a comfortable indoor climate.The “U-value” refers to the thermal transmittance coefficient, which measures how effectively building materials, such as windows or doors, provide insulation for a building. The lower the U-value, the better the insulation and the lower the heat loss.SIA “Staļi” uses only premium-grade materials in its window manufacturing to ensure maximum thermal efficiency. Our wooden windows achieve a U-value of $U \le 1.0 \text{ W/(m²·K)}$, fully meeting the strict requirements of regions like Scandinavia.We equip our wooden windows with selective low-E (low-emissivity) glass. This glass features a transparent, microscopically thin metal oxide coating on one side, providing enhanced thermal insulation.
