Sarajevo awoke to another thick layer of smog, with residents feeling the effects of severely degraded air quality from early morning. According to IQAir, the early morning air quality index was 163, categorised as unhealthy. PM2.5 particles were again the most dangerous pollutant, reaching 72,5 µg/m³, 14,5 times the World Health Organization’s recommended level. With temperatures of just two degrees, saturated humidity and no wind, Sarajevo’s basin acts like a closed chamber trapping harmful particles near ground level.
Unfortunately, Sarajevo is not exceptional. Other Bosnian and Herzegovinian cities, including Zenica, Tuzla, Lukavac, Kakanj and Visoko, frequently rank among Europe’s most polluted winter locations. Regional cities such as Belgrade, Skopje and Zagreb also frequently exceed healthy air quality limits and face similar problems. Pollution is therefore an everyday reality for millions across Balkan cities rather than an isolated issue.
In these conditions, home should be a place of safety, peace and health, possible only with proper protection. Outdated, damaged or poorly installed windows and doors easily admit cold, polluted air. PM2.5 particles pass through the tiniest cracks and gaps, seriously worsening indoor air regardless of heating and ventilation. Children, older people, those with chronic illness and anyone sensitive to pollution are particularly affected.
Quality windows and doors are therefore a crucial first defence against smog. It is often forgotten that most external pollution enters through them. Well-chosen, professionally installed products significantly reduce air infiltration, maintain stable temperatures and prevent harmful particle entry. Product quality can make the difference between a healthy and unhealthy household.
PVC systems stand out for multi-chamber profiles and advanced seals providing outstanding thermal and sound insulation, making them especially effective at reducing smog entry. Thermally broken aluminium systems add stability and durability, particularly for larger glazed areas. Wooden windows offer natural warmth and excellent insulation. Wood-ALU combines wood’s warmth and aesthetics inside with aluminium’s resilience outside for lasting, stable and effective protection against cold, polluted air.
Window and door quality affects temperature and occupants’ health. Poor products increase allergy, respiratory problem and infection risks by allowing PM2.5 particles inside, where they remain without natural circulation. In conditions experienced daily by Sarajevo and many other Bosnian and regional cities, particularly in cold months, quality products can make an enormous everyday difference.
At SAPLAST, with over two decades manufacturing and installing windows and doors, we understand that choosing correctly matters aesthetically and for health. We develop systems minimising air passage and heat loss while creating comfortable microclimates. Our PVC, ALU, wood and wood-ALU systems provide maximum protection where air quality often falls below acceptable levels.
As polluted air becomes commonplace throughout Bosnia and Herzegovina and the region, investing in quality windows and doors means investing in home health and security. Beyond energy efficiency, they become a barrier protecting airways, children and older people and keeping home a place to breathe freely.
Every family deserves windows and doors providing real protection, stability and lasting security. SAPLAST is committed to homes protected from outside influences, however thick the smog outside.
