As the demand for new build homes continues to rise, many people are excited about the prospect of moving into a modern, energy-efficient space. However, whilst these homes often come with numerous benefits, they can also present challenges, particularly concerning indoor air quality and allergic reactions. In this blog, we will explore how new build homes can contribute to allergic reactions and what homeowners can do to mitigate these issues.
The Allergen Landscape In New Build Homes
New build homes are often constructed using a variety of materials and finished that can release volatile organic compounds (VOCs) and other allergens into the indoor environment. These substances can come from:
- Building materials: Many modern construction materials, such as paints, adhesives and sealants, contains VOCs that give off gases for years after installation. The compounds can irritate the respiratory system and trigger allergic reactions in sensitive individuals.
- Insulation: Whilst insulation is is essential for energy efficiency, certain types can attract allergens. For example, fiberglass insulation can release tiny particles that may cause skin irritation or respiratory issues. Additionally, some insulation materials can absorb moisture, leading to mould growth, which is a significant allergen.
- Air quality: New build homes are often designed to be airtight to improve energy efficiency. Whilst this is beneficial for reducing energy costs, it can also trap indoor pollutants, including dust mites, pet dander, and mould spores, leading to poor indoor air quality and increased allergy symptoms.
- HVAC Systems: Heating, ventilation and air conditioning (HVAC) systems in new homes can also contribute to allergic reactions if not properly maintained. Dirty filters and ducts can circulate allergens throughout the home, exacerbating respiratory issues.
Common Allergic Reactions Associated With New Build Homes
Residents of new build homes may experience a range of allergic reactions including:
- Respiratory issues: Symptoms such as coughing, sneezing, and difficulty to breathe can arise from exposure to indoor allergens and irritants
- Skin reactions: Allergic dermatitis or skin irritation can occur due to contact with certain building materials or finishes.
- Eye irritation: Allergens in the air can lead to itchy, watery eyes, a common symptom for those with allergies.
Mitigating Allergic Reactions in New Build Homes
Fortunately, there are several strategies homeowners can implement to reduce the risk of allergic reactions in new build homes:
- Improve ventilation: Ensure that your home has adequate ventilation to allow fresh air to circulate and help dilute indoor pollutants. Consider using Mechanical Ventilation with Heat Recovery (MVHR) to maintain air quality without sacrificing energy efficiency.
- Regular maintenance: Keep HVAC systems well-maintained by changing filters regularly and scheduling professional cleans for ducts. This will help minimise the circulation of allergens throughout the home.
- Control humidity: Maintain indoor humidity levels between 45% and 60% to prevent mould growth and dust mite proliferation. Using dehumidifiers in damp areas can help achieve this balance.
- Incorporate air purifiers: Investing in high quality air purifiers with HEPA filters can help capture airborne allergens, improving overall indoor air quality.
- Choose low-VOC materials: When selecting paints, adhesives, and finished, opt for low-VOC or VOC-free products. This can significantly reduce the number of harmful chemicals released into the indoor air.
Conclusion
Whilst new build homes offer many advantages, they can also pose challenges for individuals with allergies. By understanding the potential sources of allergens and taking proactive steps to improve air quality, homeowners can create a healthier living environment. With careful planning and maintenance, it is possible to enjoy the benefits of a modern home while minimising the risk of allergic reactions. Prioritising air quality not only enhances comfort but also contributes to the overall well-being of all residents.
