Transforming Your Home Exterior: Benefits of External Wall Insulation

Jub Systems • July 1, 2024

In recent years, homeowners and builders have increasingly turned to external wall insulation (EWI) to enhance the energy efficiency and durability of solid-wall properties. This upgrade is not only an investment in the property's future but also a step towards sustainable living. Let's look at the many advantages of external home insulation and understand why it’s becoming a popular choice for both new construction and refurbishment projects.

What is External Wall Insulation?


External wall insulation involves the installation of an insulating layer to the exterior walls of a building. This layer is then covered with a reinforcing mesh and a protective render. The renders come in various finishes, allowing homeowners to achieve their desired aesthetic while adding value to the property.


If you’re still thinking, "Is insulation for external walls worth it?" here are the key benefits that might convince you.


Key Benefits of External Wall Insulation


1. Enhanced Thermal Performance


One of the primary benefits of insulating external walls is its ability to reduce heat loss. Adding a layer of insulation prevents heat from escaping through the walls, keeping your home warmer in the winter and cooler in the summer. This improved thermal performance translates to lower energy bills, as your heating and cooling systems won't have to work as hard to maintain a comfortable temperature. 


The effectiveness of external insulation for walls is often measured by its U-value. The U-value is a measure of how well a material allows heat to pass through it. Lower U-values indicate better insulating properties. When you have external wall insulation installed, the U-value of your walls decreases, meaning less heat escapes and your home becomes more energy-efficient. This improved external wall insulation U-value is a key metric in demonstrating its efficiency.



2. Weatherproofing


External insulation for walls provides a durable, weatherproof house exterior that protects your building from the elements. Whether it’s rain, snow, sunlight or wind, EWI acts as a barrier, shielding your property from harsh weather conditions. This protection helps prevent damage and deterioration, extending the lifespan of your building and its structure.


3. Condensation Control


Condensation can lead to a range of problems, including mould growth and structural damage. Insulating walls externally helps eliminate condensation by maintaining a consistent temperature on the walls, reducing the risk of moisture build-up. This creates a healthier living environment and preserves the integrity of your building.


4. Improved Appearance


With a variety of renders and finishes available, external house insulation allows you to enhance the aesthetic appeal of your property. Whether you prefer a modern look or a traditional style, you can choose a finish that complements your taste and improves your home's kerb appeal. This not only makes your property more attractive but can also increase its market value.




5. Acoustic Benefits


External wall insulation systems can also improve the acoustic quality of your home. The insulating layer helps reduce noise transmission from outside, creating a quieter and more peaceful indoor environment. This is particularly beneficial for properties located in busy urban areas.


6. Environmental Impact


By reducing heat loss and improving energy efficiency, external wall insulation products help lower your carbon footprint. This contributes to environmental conservation efforts and supports sustainable living practices. Additionally, many external wall insulation systems are made from eco-friendly materials, further enhancing their ecological benefits.

  • Minimal Disruption: Installation is carried out externally, causing little disturbance to occupants.
  • Choice of Finishes: A wide range of colours and textures is available to match or enhance the building’s original character.
  • Preservation of Internal Space: Unlike internal insulation, EWI does not reduce the usable floor area.
  • Increased Property Value: Enhanced appearance and improved energy efficiency can boost property market value.
  • Extended Building Lifespan: EWI protects and revamps older buildings, extending their usability and lifespan.

The Ultimate Guide to the Great British Insulation Scheme: Measures, Eligibility and How to Apply

By Jub Systems • July 19, 2023
Introducing the Great British Insulation Scheme, previously known as ECO+, a government initiative aimed at helping households insulate their homes, improve energy efficiency and reduce energy bills. With the scheme already launched and set to run until March 2026, it's time to discover how this £1 billion programme can benefit households across the UK. In this blog post, we'll delve into the details of the scheme, its eligibility criteria and the range of energy-saving measures available. Benefits of the Great British Insulation Scheme The Great British Insulation Scheme aims to support approximately 300,000 households by providing financial assistance for home insulation. By participating in the scheme, households can save an estimated £300 to £400 per year on their energy bills. The focus is on helping those with the lowest incomes, while also extending support to households living in energy-inefficient homes with Energy Performance Certificate (EPC) ratings of D or below, as well as those in lower Council Tax bands (A-D in England, A-E in Scotland and Wales). This inclusive approach ensures that more people, especially those struggling with high energy costs, can benefit from making their homes more energy efficient. The Aim of the Great British Insulation Scheme  The Great British Insulation Scheme has a clear goal: to deliver single insulation measures to two main groups of customers. The first group consists of low-income individuals who do not meet the minimum requirements for ECO4 assistance. The scheme aims to provide them with valuable insulation measures to improve their living conditions. The second group includes households based on council tax band and Energy Performance Certificate (EPC) rating, targeting a wider range of individuals who can benefit from energy-saving upgrades.

External Render Repair and Maintenance: Preserving Your JUB Render

By Jub Systems • July 12, 2023
Welcome to our guide on external render repair and maintenance. Whether you have a JUB render and/or an external wall insulation system, proper maintenance is essential to ensure longevity and visual appeal. By following our step-by-step instructions, you can reduce the need for extensive render repairs in the future, saving you both time and money. Let's dive into the key steps for effective render repair and maintenance. Step 1: Thorough Cleaning and Primer Application Before starting any redecoration work, it's crucial to clean the external render thoroughly. Remove any visible dirt or dust from the surface, ensuring a clean and smooth base for the upcoming paint application. If necessary, treat the facade with JUB Fungi Wash to eliminate any fungal growth or contaminants. However, avoid using acid-based cleaners or solvents, as they can damage the external wall insulation system. To enhance the adhesion and durability of the new paint, we highly recommend applying an appropriate paint primer to the cleaned render. Step 2: Choosing the Correct Paint Choosing the correct paint is crucial for achieving a long-lasting and visually pleasing exterior finish. Take into account the type of render you have and consult our technical department at technical@jub.org.uk for guidance on the suitable paint product. Avoid using masonry paint that JUB Systems UK Limited hasn't advised to maintain warranties and prevent short-term maintenance cycles. Keep the original render's colour code on file for future reference to ensure accurate colour matching.

Why Silicone Render is the Best Choice for a Property’s Exterior: Benefits, Application & Aesthetics

By Jub Systems • May 24, 2023
When it comes to a property's exterior, making a lasting impression with a beautiful and durable finish is key. That's where silicone render comes in. As a high-performance external render, it offers a multitude of benefits that make it the best choice for homeowners and renderers seeking long-lasting and visually appealing results. Benefits of Silicone Render: Why Choose It?  Silicone render stands out for its numerous advantages. Firstly, it provides exceptional weather resistance, making it perfect for even the harshest climates. It can endure heavy rain, extreme temperatures and strong winds without cracking or fading. This ensures that a property maintains its stunning appearance for years to come. Another significant benefit is its breathability. By allowing moisture to escape through the walls of a property, it prevents the build-up of dampness and condensation. This is especially crucial for older houses and buildings with potentially inadequate insulation. By opting for silicone render, you can improve a property's energy efficiency and reduce the risk of dampness and mould. Flexibility is also a key feature of silicone render, setting it apart from traditional render systems. While other renders can be brittle and prone to cracking, silicone render is designed to move naturally with the property's walls, minimising the likelihood of unsightly fissures over time.

ECO Flex: Providing Energy-Efficient Home Upgrades for Non-Benefit Eligible Households in the UK

By Jub Systems • May 17, 2023
The ECO4 scheme has been helping eligible households in the UK to access free insulation and energy efficiency upgrades to reduce energy costs and support sustainable living. However, not all households that need support with improving their homes are receiving income-related benefits. That's why the UK government introduced the ECO Flex scheme. Under ECO Flex, local authorities are provided with more funding to identify residents who would benefit from home upgrades, even if they don't meet the standard eligibility criteria for ECO4. With ECO Flex, households don't have to be on benefits to qualify for funding. ECO Flex Eligibility The eligibility criteria for ECO Flex is quite comprehensive. To qualify, your Energy Performance Certificate (EPC) rating must be between E-G if you rent or D-G if you own your home. If your property is not currently on the EPC register, we can help assess it for you. You must also have a combined household income of less than £31,000. Alternatively, if you meet the EPC criteria, you can qualify for ECO Flex if you meet the following: Your home is within a specific postcode identified by your local council. You receive a council tax rebate (single-person occupancy excluded). You are identified as vulnerable to living in a cold home: someone in the home is pregnant, disabled or elderly, you have children under 5, or someone in the home has a medical condition. Your child receives free school meals. Your home is identified as being in debt to your energy provider. Another way to qualify is if you are identified by your GP as vulnerable to the cold and on a low income.
