Ductwork Insulation Contractors

Ductwork insulation is the process of installing thermal insulation around ductwork to improve energy efficiency, indoor air quality, temperature control and prevent condensation. Ductwork in buildings is commonly found in ceiling spaces, attics, basements, walls, and under floors, serving as a crucial component of the HVAC system. In some modern designs, ducts may be intentionally left exposed for aesthetic reasons, while proper installation and design are essential for efficient heating, cooling, and ventilation. Having experienced duct insulation contractors, like our team at Thermal Clad, installing high-quality insulation around your ductwork can provide significant benefits for your home or commercial building.

Ductwork Insulation - The Advantages



Energy Efficiency

Insulation plays a crucial role in enhancing the efficiency of ducting systems and associated plant items, such as fans and Air Handling Units (AHUs). One key advantage of insulated ductwork is the marked improvement in energy efficiency. By effectively preventing conditioned air from escaping, insulation can boost efficiency by an impressive amount, leading to substantial reductions in energy costs. Moreover, maintaining the desired air temperature within the ductwork allows the HVAC system to operate more efficiently, achieving the same level of heat and comfort with less strain on the system.


Improved Indoor Air Quality

Ventilation ductwork is installed in buildings with the primary aim of enhancing indoor air quality significantly. The importance of insulating the duct cannot be overstated in achieving improved air quality. Condensation and water droplets can lead to a breeding ground for mould and fungi. Therefore, insulating your duct serves as a preventive measure against such issues. The increased exposure to mould has been associated with the onset of allergy-like symptoms, including a stuffy nose and wheezing.


Temperature Control

Another huge benefit is temperature control. Ductwork insulation allows for greater precision and reliability when it comes to controlling the temperature within your building. The thermal insulation prevents air from losing its temperature as it flows to vents and registers.


Condensation Prevention

Duct insulation forms a moisture barrier that prevents water vapour from condensing on duct surfaces. Condensation can lead to mould, corrosion, and water drips that stain or damage ceilings, walls and the surrounding infrastructure. Insulation keeps ductwork dry by maintaining an even temperature throughout. Duct insulation is also a simple way to protect against deteriorating HVAC performance and expensive repairs due to condensation issues.

Thermal Insulation for Ductwork

The main purpose of thermally insulating ductwork is to regulate and subsequently minimise the amount of heat energy that escapes from your ducts, maintaining the temperature within your property. This also improves the overall energy efficiency of your heating and cooling systems. Our professional duct insulation installers use materials like fibreglass, and rigid foam boards to surround ducts and seal them up, effectively creating a protective thermal barrier.

The process of insulating your ductwork couldn’t be more straightforward. After an initial consultation where we gather the details about your ductwork system and insulation needs, our team creates a bespoke quote, outlining the recommended insulation materials, total costs, and projected timeline. Once you review the quote and accept it, we order all the necessary insulation materials and schedule the installation. Our experienced technicians then arrive onsite to professionally install your ductwork insulation, keeping you updated on the ongoing progress of our work. With Thermal Clad, you can count on an organised duct thermal insulation process from start to finish.

Cut Down Your Energy Expenditure
