Wooden windows that cut your heating bills, dampen street noise, and stay straight for decades. Built to your exact sizes in our Kalnciems workshop, Latvia.
What matters most to a homeowner - and how our windows deliver. Certified to CE marking (EU), ready for projects up to Passivhaus standard.
Our windows reach U-values down to 0.6 W/m²K - the warmth stays in, the cold stays out. Lower heating bills every winter, year after year.
Up to 43 dB sound reduction. Quiet rooms, even on busy streets. You feel the difference the day they go in.
Designed to last 60 years - decades longer than uPVC. Premium engineered timber stays straight and holds its sealing performance year after year.
See how much energy (and money) you could save by upgrading your windows.
Estimates based on standard industry formulas (window area × ΔUw × heating degree days × 0.024). Energy cost 0.15 €/kWh (EU average). CO2 0.4 kg/kWh. Bill comparison assumes a 6-month heating season; actual savings depend on the building, heating system, and local tariffs.

Start ConfiguratorThe 8 things homeowners ask us most often before placing an order.
Standard wooden window orders ship in 6 to 8 weeks from confirmed measurements. Premium 115 four-glass orders run 8 to 10 weeks because of the laminated frame curing window. We book the installation date when production is half done, so you get a firm fitting day before the windows leave Kalnciems.
Across Latvia, yes. The quote covers delivery, fitting by our own team, sealing, and disposal of the old windows. For deliveries outside Latvia we partner with local fitters or your chosen contractor; we share the technical drawings and the SIEGENIA hardware spec so anyone qualified can fit them properly.
10 years on the frame and glazing unit, 5 years on the moving hardware (SIEGENIA), 2 years on the paint finish (TEKNOS) extendable to 5 years with our service contract. The whole policy is backed by a Latvian bank guarantee, so the cover survives even if any party leaves the market.
Higher upfront cost, lower 30-year cost. Premium engineered timber lasts 60 years, recoats every 8 to 12, and reaches U-values down to 0.6 W/m²K. Quality uPVC lasts 20 to 30 years and cannot be refurbished. Across two decades, wood typically wins on total cost of ownership for a heated home.
Yes, every window we ship is made to your measurements - there is no "standard" line. We handle arches, half-circles, trapezoids, and listed-building replicas. Send us a sketch with rough dimensions and we will come back with what is feasible and the surcharge, if any.
Yes. We ship throughout the EU plus the UK, Norway, and Switzerland. Delivery is on our own trucks for full pallets, third-party haulage for smaller orders. Customs paperwork is handled by us; you get the windows at your driveway with all certificates included.
ECO 92 is our 92 mm three- or four-glass system - U-value 0.78 to 0.67 W/m²K, the volume seller for new builds and renovations. Premium 115 is the 115 mm four-glass profile that hits Uw 0.6 W/m²K, designed for Passivhaus and heritage retrofits where the wall depth allows it. The full profiles overview covers all dimensions.
Included. Our fitters remove the old units, dispose of them according to Latvian environmental rules, and clean up the area. Glass and wood go to recycling streams; uPVC frames go to certified processors. You get a disposal certificate if your project needs paperwork for renovation grants.
