External wall insulation has become increasingly popular in recent years, as homeowners and contractors seek to improve the energy efficiency and appearance of buildings. One of the key considerations when choosing external wall insulation is the thickness of the insulation material. In this article, we will explore the benefits of 90mm external wall insulation, also known as 90mm EWI.
90mm external wall insulation is a type of insulation that is applied to the exterior of a building, typically consisting of a layer of insulation material such as expanded polystyrene or mineral wool, covered by a render finish. The thickness of the insulation material can vary, and 90mm external wall insulation is considered to be one of the most effective thicknesses for improving thermal performance.
One of the main benefits of 90mm external wall insulation is its thermal performance. By adding a layer of insulation to the exterior of the building, heat loss through the walls is significantly reduced, helping to keep the building warm in the winter and cool in the summer. This can lead to lower energy bills and a more comfortable living environment for occupants.
In addition to improving thermal performance, 90mm external wall insulation can also help to reduce condensation and damp issues within the building. By creating a barrier between the internal and external environment, the insulation helps to prevent cold spots on the walls where condensation can form. This can help to reduce the risk of mold growth and other moisture-related problems.
Another benefit of 90mm external wall insulation is its impact on the appearance of the building. The insulation can be finished with a variety of render finishes, including smooth, textured, and painted finishes, giving homeowners the opportunity to customize the look of their property. This can help to improve the overall curb appeal of the building and increase its value.
Furthermore, 90mm external wall insulation can also help to improve the acoustic performance of the building. The additional layer of insulation can help to reduce noise transmission through the walls, making the building quieter and more peaceful for occupants. This can be particularly beneficial for buildings located in noisy urban areas or near busy roads.
When it comes to installation, 90mm external wall insulation is relatively straightforward and can be carried out by experienced contractors. The insulation panels are fixed to the exterior wall using adhesive or mechanical fixings, and then covered with a render finish. The entire process can usually be completed within a few weeks, depending on the size of the building and the weather conditions.
In terms of cost, 90mm external wall insulation is considered to be a cost-effective solution for improving the energy efficiency of a building. While the initial investment may be higher than some other insulation options, the long-term savings on energy bills can make it a worthwhile investment. Additionally, the improved appearance and potential increase in property value can also make it a sound financial decision.
Overall, 90mm external wall insulation offers a range of benefits for homeowners and contractors looking to improve the energy efficiency and appearance of buildings. From improved thermal performance and reduced condensation to enhanced curb appeal and acoustic performance, the advantages of 90mm EWI make it a popular choice for a wide range of properties.
In conclusion, 90mm external wall insulation is a versatile and effective solution for improving the energy efficiency and appearance of buildings. With its range of benefits and relatively simple installation process, it is a popular choice for homeowners and contractors alike. By choosing 90mm external wall insulation, property owners can enjoy a more comfortable living environment, lower energy bills, and a more attractive property.
