Why Invest In Ventilation?
Safe working environment
Heat will build up in your roof space in summer and can at times reach 70°C. Bradford Ventilation removes the heat and replaces it with cooler, purer ambient air. This helps reduce the load on air conditioning, particularly when used alongside ducting, increasing energy efficiency.
Protect equipment and its performance
Capital equipment should be used in normal operating temperatures to provide best performance and can be subject to failure in high humidity areas. Removing humidity from the air can reduce failures in electronic and mechanical equipment.
Air quality and pollutants
In an unventilated industrial environment, pollutants such as carbon monoxide emitted by gas forklifts, can be particularly harmful. Bradford Ventilation commercial systems exhaust pollutant indoor air and increase overall air quality.
Benefits of a well ventilated building
Eliminate smell
Bacteria and fungus thrives in damp humid conditions. A well ventilated building, using Bradford Ventilation ventilators, can reduce and control humidity levels within the enclosed area
Decrease infections, asthmas and other respiratory issues
During exercise many of us inhale through our mouth, bypassing the body’s natural filters, and air goes straight into the lungs. Breathing in spores and dirt where the air-flow isn’t properly maintained could cause more harm than good.
Increase comfort and performance
Excessive heat build-up inside a building can cause discomfort and decrease concentration and performance.

Home Ventilation Solutions
Effective ventilation is an important way to create a more comfortable, energy-efficient and healthier home. Removing heat in summer, controlling moisture & encouraging fresh air into your home will help create a better environment for your family.

Always Dry Home
Moisture in the air produces mould and condensation. This can lead to a higher chance of developing respiratory illnesses or asthma. A drier home is also easier and cheaper to heat and cool.

Healthier Home
Indoor air quality matters, ventilation systems have advanced air filters which reduces the risk of airborne viruses, mould issues, asthma and other respiratory problems

Energy Efficient Home
With less moisture in the air, less energy is required to heat which will help reduce your monthly heating bills over winter. A sensible investment for landlords; reduce the continued maintenance and upkeep caused by damp homes.

Home Ventilation System
Effective Ventilation of your living space is an important way to create a more comfortable, healthier and energy efficient home

Heat Recovery System
Heat recovery ventilation systems remove warm and damp air from living spaces and pass it through a heat exchanger, which warms up fresh, cool air from outside. This maintains air quality and minimizes temperature changes

Kitchen Extraction System
Use a kitchen extractor to remove cooking odors and grease. Ensure that it vents externally to prevent moisture buildup in your home. A directly placed extractor above the cooking surface is the most efficient solution.

Bathroom/ Toilet Extraction System
Excessive bathroom steam and humidity can lead to the growth of unhealthy mould. It's important to address the underlying cause to prevent further growth and breeding.

Getting Rid of Crying Windows and Mould
Excess moisture in the home can display itself in the form of crying windows. However, there is a solution to this problem. Effective ventilation can help reduce humidity levels in the home, promoting the exchange of fresh air and preventing the accumulation of moisture that leads to crying windows and mould growth. Proper ventilation is key in managing moisture levels and preventing condensation, dampness, and mould growth. Controlling moisture in your home helps preserve its structural integrity and promotes a healthier living environment.
Enhance Your Well-being by Breathing Clean Indoor Air Quality
Installing a Home Ventilation System can help improve respiratory health by ensuring a constant supply of fresh air while removing stale air, odors, and other airborne contaminants. Effective Ventilation in your home cab be a great way to reduce airborne allergens, mould, and excessive humidity. This is especially important when it comes to protecting children in New Zealand who suffer from asthma. With cleaner, healthier air to breathe, you and your family can enjoy a safer and more comfortable living environment.
Improving Energy Efficiency with Proper Ventilation:
Home Ventilation systems are an excellent way to keep your indoor temperatures comfortable all year round. By improving air circulation, they help prevent hot or cold areas, which means you can rely less on energy-consuming heating and cooling systems. In fact, ventilation systems can even improve the efficiency of your heating and cooling, meaning you'll save money on energy costs.
