External Wall Insulation
Insulating solid walls with external Wall Insulation (EWI) can help reduce some of the 35% of heat loss that occurs from this area of a property.
EWI is a fantastic solution that can insulate older properties and those that that don’t have post-1930s cavity walls. External wall insulation has a greater impact on the energy efficiency of a property than brand new A-rated double glazing or a new condensing gas boiler.
Using the BBA-approved EWI Pro (www.EWIPro.com) external wall insulation solution will improve the thermal performance of walls, so that not only do they feel warm to touch but it should reduce condensation and the potential for mould buildup due to insufficient heating in the property.
The U-value (measurement of heat loss – the lower the number the better) of a typical 220mm solid brick wall is between 1.9 to 2.2W/m²K – applying 100mm of the EWI Pro expanded polystyrene (EPS) solution with mechanical fixings, reinforcing adhesive and a silicone-silicate should bring down the U-value of the walls to 0.27W/m²K (better than current building regulations for new builds – 0.28W/m²K).
Our external wall insulation systems also provide a significant upgrade to the appearance of your property. We offer a huge range of different finishes, including different render granularity, almost limitless colours, brick slips and even pebble dash systems.
For peace of mind, we are delighted to be able to offer a 25 year manufacturer-backed guarantee with our EWI systems. So not only do you save on your bills and improve the look of your home, you can feel comfortable in the knowledge that the system will stand the test of time!
How is external solid wall insulation installed?
EWI is installed by applying a layer of EPS to the outside of the exposed walls of your home. The material is stuck to the walls initially with concrete adhesive and then reinforced by mechanical fixings and plastic caps.
The system is further reinforced by a layer of adhesive and reinforcement mesh before a final render (and optional layer of brick slips) is added. The system should prove to be a durable solution, lasting the test of weather and time, whilst providing superb insulating performance.
How long does the installation process take?
The install time is very dependent on the size of the property, but since the different layers take time to dry, you should expect a job to take between 1 and 2 weeks. The good news is that since all the work is external, there should be very little upheaval for those living in the property at the time.
What areas does BeConstructive cover?
We are pleased to announce that we now install solid external wall insulation nationwide. Initially we were focused solely on installing solid wall insulation in the London area, but demand for our services has resulted in us vastly increasing capacity, so wherever you are in the UK we will be able to help!
