fire safe

Stay safe in your home. Old and worn-out façades are constantly exposed to weather conditions and can be adversely affected by damage, which may cause cracking. Any openings will let the moisture penetrate your walls. Our EWI systems can provide a new, durable, rock-solid and crack-resistant façade.


We want you to feel safe in your home. There are very clear UK Building Regulations referring to Fire Protection Requirements for EWI Systems. The insulation systems are classified in relation to their reaction to fire. Houses up to 2 storeys should be insulated with a system not less than C class (Low Risk). What is the classification for Soltherm systems then? All the mineral wool based systems are classified as class A - they are non-combustible. All the systems with EPS boards are classified as B.The Soltherm insulation systems are adhesively bonded. What does that mean? It simply means, that the adhesive creates an additional barrier against the spread of fire. This barrier is not present in dry fixed systems, which is why the fire on those buildings may spread quickly and pose much more of a threat.

wind load

Windloads can pose a serious threat to the fabric of the building. Soltherm has prepared Cross Knot - a unique solution, which combines the full forces of the insulation material. In this patented Soltherm solution, a special mechanical fixing goes through two crossed fibreglass mesh strips to provide extreme resistance to wind loads. A standard fixing provides a reinforcement area that is restricted to the support washer area, however with Cross Knot this area is extended as the crossed strips are both attached to the insulation material as well as fixed to the reinforcement. The mechanical fixing used in this process has the capability to hold down the insulation due to a screw-in fixing which can be tightened. This is ideal for tall buildings, to ensure optimal security and safety during high winds.


The home of your dreams

The wide range of render colours and decorative effects will make your home unique. Our graphic artists will help you design your façade.

Extend the life of your property.

Did you know that properly insulated buildings are protected against moisture as well as from cracking and thus remain in good shape for many years?

Enjoy the new look of your home for many years.

Our render systems are algae-resistant and can be easily pressure-washed.

energy efficient

Improve your indoor comfort

Proper temperature is as important as proper humidity. Did you know that the indoor temperature should be constant all year round? Let’s look at other aspects of healthy life with EWI.

The temperature should be constant between 19 and 22°C. The humidity should be between 40 and 60%.

Condensation and mould in poorly insulated buildings can cause serious health problems.

We know how important it is to keep your home peaceful and quiet. Sleep can be disrupted by as little as 35dB (normal street sounds). Insulated walls help cut noise from outside your home.

Did you know that the average British citizen contributes 1.49 tons of CO2 a year through the heating of their home?

unhappy with your fuel bills?

By installing EWI you will reduce the need of heating, and therefore reduce your carbon footprint and your energy bills!

reduced heating costs

Do you know that the efficient insulation can reduce bills by up to 40%? The estimated annual savings vary from £260 for a semi-detached gas-heated house to £455 for a detached one. And what’s more, you will be less vulnerable to rises in energy costs.

reduced electricity bills

An insulated house maintains a comfortable indoor climate, which in turn results in a reduced use of appliances like air conditioning or fans.

best value

increase the value of your property

The investment in EWI will lower maintenance costs as well as energy consumption, ensuring that your house will meet current and future U-value regulations. Buildings with EWI can get much higher prices on the properties market.

With all the money that you can save with us, you better start thinking about what you’ll spend your money on!
