External blinds: Cut your energy costs and carbon footprint 

As style-conscious UK homeowners continue to invest in larger glazed areas, managing indoor temperatures efficiently has never been more important. External blinds are emerging as one of the most effective energy-saving blinds available, helping to reduce both heat gain and heat loss throughout the year. By improving thermal performance and cutting the need for artificial cooling or heating, they offer a practical way to lower energy bills while reducing environmental impact.

Energy-saving blinds and the importance of heat control

Large windows and glazed doors bring daylight and a sense of openness, but they also invite solar radiation. Without proper shading, the temperature of your room can rise quickly on sunny days, forcing reliance on electric fans or air conditioning. This approach increases energy use and costs.

External blinds are designed to block up to 97% of solar heat before it even reaches the glass. This passive cooling method keeps interiors at a more comfortable temperature and reduces the demand for mechanical systems. Unlike internal solutions such as thermal roller blinds or blackout blinds, external blinds stop heat at the source, preventing hot air from building up indoors.

A study by the British Blind & Shutter Association (BBSA) demonstrated that external blinds can reduce internal room temperatures by up to 19.5 centigrade, thereby minimising if not mitigating the need for active cooling all together.

Benefits of external blinds in winter

Energy-saving blinds are not just for summer. During colder months, external blinds can help trap heat by adding a layer of air between the window and the blind, improving insulation. This added thermal barrier reduces heat loss, supporting energy efficiency even when temperatures drop. A further study by the BBSA demonstrated that external zip blinds can reduce heat loss by up to 21% with common double low-e glazing.

For homes with roof lights, bifold doors or large expanses of vertical glazing, this added insulation is especially valuable. Some blinds, such as the Cayman model, are engineered specifically for horizontal glazing, where heat loss can be more pronounced.

A sustainable choice for all types of homes

From detached houses to flats and rented properties, external blinds suit a wide range of window types and living arrangements. The intelligent control systems offered by Caribbean Blinds allow blinds to respond to changing conditions automatically.
