Thermal Insulation Contractors
Thermal insulation is the reduction of heat transfer between objects in thermal contact or in range of radiative influence. This can be achieved with specially engineered methods or processes, as well as with suitable object shapes and materials. Put simply, it refers to the many ways we attempt to prevent the transfer of heat from one object to another.
Thermal Clad are thermal insulation contractors, providing high-quality services in all aspects of the trade and are backed by a fully-skilled workforce who specialise in thermal insulation installation. We have our own fabrication workshop and expert guide that allows for efficient work and a quick turnaround on all our jobs.
Thermal Insulation for Pipes & Ductwork
Thermal insulation plays a very important role for businesses wanting to lower their carbon footprint and save on energy costs. In commercial and industrial buildings, where pipes transport hot fluids, gases, or chilled liquids, and where HVAC systems circulate air through large ducts and vents, proper insulation serves to safeguard against heat loss or gain. This results in reduced energy consumption, lower operational costs, and better sustainability.
As leading thermal insulation contractors, we offer tailored solutions that not only maintain the desired temperature of fluids and air but also prevent condensation, which can cause corrosion and system inefficiencies. By investing in high-quality thermal insulation for pipes and ductwork, your business not only ensures regulatory compliance but also demonstrates your commitment to protecting the environment and the responsible use of resources.

Thermal Insulation - Key Benefits


01.
Reduced Energy Costs
This is one of the most important benefits of installing thermal insulation. When applied correctly, this type of insulation reduces the energy expenses of your building. Once implemented, you can use the required energy more efficiently and effectively, without hindering comfort in your daily life. Minimising waste energy has never been more important and we are dedicated to being a part of solving these issues.
02.
Increased Fire Protection
Building services are an essential part of nearly every building, whether it’s the distribution of cold and warm air through HVAC systems or providing active measures of fire protection through sprinkler systems.
As building services are distributed to various parts of a building, it is common for these services to pass through compartment walls and floors. Building services like smoke extractor systems or sprinkler systems provide active measures of fire protection which often require their own level of fire resistance.
Ensuring that building services can operate safely and do not contribute towards the spread of fire within your building are key considerations for any fire safety strategy. As thermal insulation contractors, we are able to supply and install a range of products from leading insulation manufacturers that have been specially designed and manufactured for fire-protecting ductwork and pipework.
03.
An Environmentally Friendly Solution
When the pipework and ductwork services are properly insulated in a building, it will help save money on utility costs, contribute to a cleaner atmosphere, plus, minimise leaks, heat loss and condensation issues. Heating and cooling buildings can account for a vast amount of all energy consumption. Reducing the required energy demand can reduce both operating costs and carbon emissions for many large constructions – such as airports, apartment blocks, warehouses and schools.
Thermally insulating the services within a building is an environmentally friendly solution that helps to push for environmental and ecological balance. Less energy is used for heating, cooling and climatisation of the building; reducing the consumption of fossil fuels such as coal and natural gas. You’re not only saving money on your energy but also consuming less electricity and helping to save our planet. The environmental implications of the energy savings go right to the heart of global climate change, simply because less energy consumption means less emission of greenhouse gases.
04.
Reduced Emissions of Pollutants
As mentioned previously, installing thermal insulation helps to reduce our electricity consumption. Not only are we using less, but we are also minimising the spread of harmful emissions and pollutants. Emission of carbon dioxide (CO2), sulphur dioxide (SO2) and other harmful greenhouse gases spreading into the atmosphere is minimised and the negative effect on the ecological balance is reduced.
Thermal insulation is a vital measure we can take to help prevent global warming and climate change.
05.
Personal Protection
Personal Protection insulation is provided to avoid personal injury. All exposed pipework and ductwork surfaces of high temperatures (which could potentially cause serious injury if contact is made with them) can be provided with thermally insulating personal protection. The installations usually consist of industrial plants with associated ductwork and pipework systems, which are accessible by the end-user and operating personnel, therefore, need to be at a safe temperature to touch.

Thermal Insulation - FAQs
Thermal insulation is designed to prevent the transfer of heat (thermal energy) between two objects or areas in close contact or proximity. Covering your pipes and HVAC systems with this material helps to prevent unwanted heat transfer. Several different materials can be used to achieve this, including phenolic foam, glass fibre and mineral wool. Each of these methods proves incredibly effective and the type you will need ultimately depends on the intended purpose.
In a way, yes. Thermal insulation essentially prevents the transfer of heat. This means that things that should be hot remain hot and things that should be cool remain cool. For instance, if you insulate your industrial pipework, the hot water inside the pipes won’t lose temperature. Meanwhile, the outside of your pipes won’t overheat, thus serving to reduce any potential fire or burning hazards. Whilst thermally insulating your pipes won’t heat things up or cool things down directly, it will ensure that the elements you are protecting remain at the ideal temperature.
At Thermal Clad, we only supply the best kinds of thermal insulation available on the market. Indeed, more than forty years of experience have taught us which materials work best in each individual situation, allowing us to tailor our solutions to your exact industrial needs.
Fibreglass is another commonly used material made from pure sand and fragments of recycled glass. Because it is slightly porous, any air that passes through is trapped in the fabric, serving to reduce the sound impact as a result. Mineral wool is similar to glass fibre insulation, however, it tends to be denser and stiffer for greater impact. This type of material proves incredibly effective when it comes to preventing heat transfer, helping to reduce your emissions whilst also producing significant energy savings. It also reduces noise pollution and, because it is non-combustible, provides enhanced fire protection, as well.
Nevertheless, if you require enhanced moisture resistance in addition to strength and effective heat insulation, phenolic foam is likely the best solution for you. Phenolic Foam is frequently used for chilled and cold water applications, where insulating pipes and vessels is essential.
Generally, all thermal insulation products essentially serve to reduce the amount of heat lost from pipework and ductwork systems, ensuring that your plant and energy usage remains as efficient and cost-effective as possible.
Thermal Clad specialises in the provision of commercial and industrial thermal insulation solutions for pipework and ductwork applications. We are perfectly positioned to serve clients across a variety of sectors, including industry, healthcare, manufacturing and education. To find out how we may be able to help you, get in touch to discuss your specific needs or request your free quote.
In the UK, pipework and ductwork insulation are governed by the BS 5422 standard, which specifies the need to comply with current Domestic and Non-Domestic Building Service compliance guidelines. This standard is reviewed periodically, so it’s important to ensure you keep up to date. Thermal Clad is well-versed in all compliance issues, guaranteeing that the materials we provide not only serve your building well but also adhere to all relevant rules and regulations.
Although it is possible to install new thermal insulation over existing solutions, this is not always recommended. Whilst the additional layer can serve to further boost protective properties, it all depends on the condition of your original layer and whether or not it is compliant or in poor condition. We would always recommend removing the existing insulation and starting again.
The exact price of your thermal insulation will depend on the size and scope of your project. At Thermal Clad, our efficient estimating department has the experience required to provide accurate estimates and free quotes.
Yes. One of the significant benefits of quality thermal insulation is that it reduces heat loss. When less heat energy is able to escape and less condensation is able to form, you will consume far less energy to keep your building or fluids at the correct temperature. This reduction in energy usage ultimately translates into lower energy bills and, perhaps more importantly, a reduced carbon footprint. Thermally insulating is therefore essential for all businesses and service providers looking to run their buildings as efficiently as possible, helping reduce greenhouse gasses and protect our planet.
At all projects, Thermal Clad will only install products supplied by industry-leading brands. We only purchase products from manufacturers with proven manufacturing processes and certification to prevent pollution and minimise emissions to air, land and water.
Schools, hospitals and various other types of commercial buildings have ventilation systems to ensure the building’s efficiency, productivity and indoor air quality. We are able to install high-quality thermal insulation to ductwork systems, which in turn will help reduce energy wastage, resist damage to the building caused by condensation forming on ductwork with ceiling spaces, and reduce noise for a more effective environment for the building occupants.
Pipework installation within a building requires the correct insulation in order for the effective running of the plant and to minimise a building's energy consumption. Whether it’s heating chilled water or hot and cold pipework, temperature consistency is crucial. Insulating delivers a better process by maintaining the temperature along the pipework from pipe entry to exit. This can lead to greater operating efficiencies and reduced energy loss, which, in turn, can lead to reduced energy costs.
Fitting a layer of insulation to pipework greatly improves its thermal properties, and the best performance is achieved when it is fitted correctly. Pipework insulation is manufactured in sections. This means that it is manufactured to fit the diameter of the pipe, therefore when the pipe diameter is known, the correct materials can be purchased and installed.
Thermal Insulation contractors specialise in insulating industrial and HVAC mechanical systems such as pipework, ductwork, tanks and other ancillaries such as valves and flanges. It is important to insulate these systems in order to maintain the temperature and air quality within a building envelope. Without insulation, heated or cool air and fluid that is being transported through the ducts and pipes can be reduced, resulting in a less efficient building. A contractor, such as Thermal Clad can ensure that these systems are insulated to the correct industry standards. When employing the services of a contractor it is important to employ a company with a reputable reputation.
