Why buy a Thermal Shutter?
With modern homes becoming increasingly well-insulated to conserve heat during the winter, it's easy to overlook the critical need for cooling in the summer. With global temperatures rising, homes are more likely to experience overheating during summer months. Alarmingly, studies predict that by the mid-2030s, a staggering 90% of existing homes will face overheating risks.

Introducing Dunster House Thermal Shutters!

Our innovative thermal shutters provide year-round comfort by addressing both heat loss in the winter and heat gain in the summer. Unlike standard shutters, they are designed with advanced insulation technology to improve energy efficiency in all seasons.

In summer, the shutters act as a barrier, reducing solar heat gain and keeping your home cooler by minimising the amount of heat that enters. In winter, they trap heat inside, preventing it from escaping through windows and helping you reduce energy costs.
Environmental Benefits
Our Thermal Shutters significantly reduce the need for air conditioning in the summer and artificial heating in the winter, helping to lower your energy consumption. This leads to a smaller carbon footprint, reduced harmful emissions, and a more sustainable home. By choosing our energy-efficient shutters, you're making a conscious decision to reduce your environmental impact.
Health Benefits
By minimising the circulation of dust, allergens, and pollutants typically spread by HVAC (Heating, Ventilation, and Air Conditioning) systems, our Thermal Shutters significantly improve indoor air quality. This creates a healthier living space with reduced exposure to irritants. Maintaining a comfortable indoor temperature with our Thermal Shutters also promotes relaxation and reduces stress, further boosting health and daily comfort.
