Demeca’s natural ventilation solutions have been developed through different farms and customer needs to serve all types of farms. We manufacture our products in Haapavesi from the best materials. We only use two-sided UV protected and corrosion resistant materials.

Improved indoor air – more milk and meat

The quality of indoor air and temperature control have been studied to have significant impact on productivity. Our customers have very good experience with noticeable rise in output levels. The ventilation investment payback period is usually very short.

And most importantly: DEMECA windows enhance natural ventilation and increase productivity and animal comfort. This means cold cash for the farmer.

Healthier animals

Respiratory illnesses reduce yield and growth. Humid and indoor air that is too warm promotes bacterial activity and increases mastitis. Improving indoor air produces significant savings in medical and veterinary expenses. Silent ventilation without loud fans reduces noise-related stress and increases productivity. The number of flies in the barn decreases, when ventilation works optimally.
