Breathing Easier: The Asthma-Friendly Advantages of Double Glazing in Your Home

Living with asthma is challenging, especially in environments where air quality is compromised; a reality for many cold and damp homes in New Zealand. Where possible, making changes to your home environment can significantly alleviate symptoms and improve overall quality of life. One such change is investing in double glazing for your windows. Below, we'll explore how double glazing can create an asthma-friendly home environment by enhancing air quality and reducing triggers that exacerbate symptoms.


The Role of Windows in Indoor Air Quality:

Windows play a crucial role in indoor air quality by facilitating ventilation and natural light. However, traditional single-pane windows may inadvertently introduce outdoor pollutants and allergens into the home, exacerbating asthma symptoms. Double glazing, also known as insulated glazing, consists of two panes of glass separated by a layer of inert gas. This design provides several advantages for asthma sufferers:

Enhanced Insulation:

Double glazing improves thermal insulation, reducing heat transfer between the interior and exterior of the home. This helps maintain a more consistent indoor temperature, minimising the need for heating or cooling systems that can introduce outdoor pollutants.

  • Reduced Drafts and Air Leakage: Double glazing creates a tighter seal compared to single-pane windows, preventing drafts and minimising the infiltration of outdoor allergens and pollutants into the home.

  • Noise Reduction: In addition to improving air quality, double glazing can also reduce noise pollution from outside sources such as traffic, construction, and neighbours. This quieter indoor environment can promote better sleep and relaxation, which are crucial for managing asthma symptoms.

  • UV Protection: Some double glazing options incorporate low-emissivity (low-E) coatings that block harmful ultraviolet (UV) radiation from entering the home. UV rays can trigger asthma symptoms in some individuals, making UV protection an important consideration for asthma-friendly homes.


For individuals living with asthma, creating a supportive indoor environment is essential for managing symptoms and improving overall well-being. By minimising the infiltration of outdoor pollutants and allergens, double glazing helps create a cleaner, healthier indoor environment where asthma sufferers can breathe easier and enjoy a better quality of life. Consider consulting with one of our reputable double glazing specialists to explore options that suit your home's needs and budget, and take proactive steps towards creating an asthma-friendly living space.
