Duct Insulation

Ducts are a series of interconnecting network that helps conditioned air travel to the nook and crannies of your home. With a forced heating and cooling system being used in most of the houses in the UK, you need to ensure that you get the most out of the energy you spend to warm or condition the air indoors.

While insulating lofts, walls, roof and floor insulation are sure-shot ways to keep the heat indoors, we must remember that the smallest of gaps is sufficient for the warm air to escape. These tiny gaps, when left undetected, probably cause the most damage. Small holes or gaps, in wall insulation, may be easy to spot, but they are not easily detected on ducts. 

These tiny gaps in the insulation can make you lose nearly 20-30% of heated air, thus wasting resources and hard-earned money. With nearly 30% of heat loss, the boilers will have to work extra hard to maintain the indoor temperatures. 

Ductwork needs to be properly insulated and that is why we have put together this duct insulation material guide wherein we will be discussing the cost of installing duct insulation, materials used etc.

2) Improved Air Quality:

When ducts are not installed or if they have gaps or tiny cracks in them, not only do they lose heat, but they also suck the impurities in the air and circulate it throughout your home, leading to health issues. When ducts are properly insulated and secured, such instances will be a rare occurrence.

3) Prevents Condensation:

Duct insulation prevents ducts from condensing and sweating. The ducting network that pretty much runs in every corner of your house also runs by uninsulated spaces like garages or crawl spaces. 

When the warm air passing through an uninsulated duct travels through spaces with little to no insulation, it will lose heat and condense. Condensation on ductwork could damage the floor, walls or roofs etc.

Since duct insulation acts as a protective cover around the ductwork, they increase the dew point, which eliminates condensation. Plus, most of the duct insulating materials like ductwrap and duct boards have factory-applied foil-facings, which act as a moisture barrier. 

4) Improved H&V system:

Duct insulation ensures that not only your ducts but your entire H&V system functions to its optimal potential. With improved energy efficiency, the H&V system will not be under too much stress and will perform better for a longer period.
