The number of UK homes overheating in summer quadrupled to 80% over the past decade, according to a new study...read more
A clear correlation between excessive heat and cold can be seen with increases in excess mortalities. Year over year, as global temperatures become more extreme, the number of excess mortalities grows.
The need to protect against heat loss and heat gain is increasing year over year.
How our thermal shutters can help – We’ve got the stats to prove it!
Our thermally insulated shutters provide insulation against cold and heat, making them beneficial not just in winter, but also in summer, by keeping homes cooler and reducing the need for air conditioning.

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.
