External Rendering: The benefits of rendering a property

Jub Systems • July 27, 2022

The art of external rendering can be traced back to well before ancient Roman times when mixtures of lime and sand were used. As you might imagine the craft has evolved and we can now see the external rendering of a property has become quite popular in the UK in recent years. 


The potential of external render to fully transform an old house or even a new-built is undoubtedly worth exploring. Especially if combined with external wall insulation, which can further add value in terms of improving the property’s thermal performance and appearance. Thus, we’ve prepared a list of the main benefits of rendering a house and help answer your question “Should I render my house?”.

It helps the property breathe and prevents future damp problems


What does it mean for a house or a building to be able to breathe? All buildings absorb and release moisture, which is called breathability. Rain can affect the moisture levels of the buildings, however, it also comes from our day-to-day activities that release water vapour. This water usually moves inside or outside through the walls of the property.


Where the external render comes into play is that it still allows for moist air to escape outside through the walls, which will prevent condensation inside, but its key purpose is to not let moisture penetrate from the outside to inside the property. 


It’s crucial to remember that render can prevent damp from development but it’s not a solution if a building already has that issue. If you have a damp issue, we highly recommend carrying out an investigation of the property before you install render.


External render is highly versatile


Your decision of having render installed on your home or property isn’t limited by the type of building. Just as we mentioned above, renders have evolved and there is a huge range to choose from to fit your requirements and needs (especially if you go for JUB renders).


You can achieve any new look that you prefer for your property. There are smooth renders that offer a clean and sleek appearance. There are also external renders that can imitate brickwork: brick render & brickslips. Making this choice will also be accompanied by the decision of choosing the right type of render. We’ve put together a blog that goes over all these details: just click here.


Additionally, renders offer you an exclusive solution. Let’s say you have an old pat of the house but an extension has been added. Having external render installed can help blend them both seamlessly.


External render improves both thermal performance and the appearance of the property


To begin with, let’s discuss the benefit of improving the thermal performance of your home or property. The combination of external render and external wall insulation is a certain way to keep a building warm in winter and cool in summer. Most importantly it will help increase your energy savings as the insulation will keep heat from escaping.


As for the exterior’s appearance, render offers a beautiful new topcoat to an older-looking property that might have existing, aged traditional render. A new coat of render can really give your property a facelift, making it look like new.


When it comes to contemporary buildings, rendering can be used on its own or as part of a range of materials to create interesting, striking homes. Since external renders can be tinted in any colour you like (JUB’s colur chart offers over 500 standard colours), you can combine different colour combinations for different parts of the property. 


We’re happy to supply you with all kinds of different projects that have been completed using JUB renders for your inspiration.


If you decide to have external render installed, your project will require a qualified expert installer. We have an extensive list of JUB Approved Contractors nationwide that can ensure the perfect finish for your property. Get in touch with our team at info@jub.org.uk

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.
