Energy Efficiency

We took our products to a UKAS accredited laboratory to test all aspects of Emperor Paint masonry products, including water resistance, durability, heat retention and breathability. To determine the heat retention of Emperor Paint products samples coated with each of our products were compared against untreated samples. The results found that after being subject to accelerated weathering, the samples treated with Emperor Masonry Paint and Emperor Masonry Creme were on average 6°C warmer than the untreated samples. This meant that the products passed the EAD 040083-00-0404 (external thermal insulation composite) Quality Standard, which is the same given to external wall insulation.

If the exterior walls of your home are absorbing moisture, this will contribute to higher levels of heat loss which ultimately means that your energy bills will be higher. By applying Emperor Masonry Paint or Emperor Masonry Creme, you prevent this moisture absorbing into your walls, making them more energy efficient and preventing unnecessary heat loss. The saving you can make varies depending on the amount of moisture, the type of construction and a number of other factors.

Both Emperor Masorny Paint and Emperor Masonry Creme contibute to higher levels of energy efficiency as these are designed to keep exterior walls dry.

No, our masonry products only help retain heat by keeping exterior walls dry and thus reducing the rate of heat loss. This will not trap heat in the summer months.

Emperor Masonry Paint and Emperor Masonry Creme have been tested to the same level as any extermal wall insulation must be tested to, in order to prove it is an external insulating system (EAD 040083-00-0404 – External thermal insulation composite). All properties can experience benefits in thermal performance, the level of which depends on the property. Our masonry products are highly recommended for use on properties with cavity wall insulation in order to ensure the insulation stays dry and thus can perform at its best.

The amount of money you can save depends on the type of construction you have. There are two broad forms of construction; solid walls, which as the name would suggest, consist of one singular wall all the way through, and cavity walls, consisting of two layers of wall that have a 'cavity' or 'gap' in the middle. With solid walls, there is nothing preventing moisture from transferring from the external wall into the internal wall. This can allow them to become highly saturated and particularly prone to heat loss and poor energy efficiency. Properties with cavity walls prevent this bridge of moisture, allowing them to release water more effectively, although they can still suffer from heat loss due to saturated exterior walls. Cavity walls that have been installed with poorly fitted cavity wall insulation can also be prone to heat loss, as this insulation can absorb moisture like a sponge, causing it to lose thermal performance.
