What Is Loft Insulation and How Does it Work?
Loft insulation is a type of insulation for the home that can stop the rise of heat, and make your roof or attic work as a shield between the heat inside your home and the cold air outside.
What Is Loft Insulation And How Does It Work?
It works by lowering the loss of heat from the roof. Thus, it also proves to be cost-efficient, as you need less fuel for heating your home space. Once your home space gets heated up, much of the heat goes out through the roof, through convection as well as conduction.
What Is The Purpose Of Loft Insulation?
Around 25% of the heat gets lost in non-insulated homes through the roof. Thus, when you fit insulation in the roof space, attic or loft, it can make your home more comfortable to live in. Once set up, insulation can be last for over 4 decades. Thus, you can get more value for your money when it comes to saving on energy bills, given that loft insulation cost is relatively low.
When you set up loft insulation, it can also be eco-friendly, and help lower the carbon footprint in your home. It can save you money and reduce emissions.
What insulation do I need for my loft?
Polyurethane spray foam
Spray loft insulation in the UK is applied to the roof’s underside, directly over the roofing felt, tiles or slates. They can bond to each other as well as to the rafter timbers that bear the load. Once set up in place, spray foam loft insulation can lessen your energy expenses by as much as 20%. You can also reduce your carbon footprint significantly. Spray loft insulation cost is slightly high, but you can recover many times over the spray loft insulation cost.
This is low-cost and light in weight and composed of volcanic rock that is heated until melted. Then, it is spun and oil and resin are used for binding it all together. It is available in blanket rolls that can simply be laid down between joists and placed atop to get the suggested depth.
It can be used to insulate rafters and joists, and is ideal for the absorption of moisture, thus preventing rot and mold. You can use natural and soft sheep’s wool to wrap the loft up. It is non-irritant for the skin.
How Loft Insulation Prevents Heat Convection?
Your loft loses more heat as most insulating materials are bad conductors of heat. These insulating materials stop the air circulation inside your house by the convection method. However, you can reduce this heat loss by using spray foam loft insulation. For insulating your cavity wall, you need to follow this same method.
How can you Stop Conduction and Convection?
Cavity wall insulation – The insulation material comprises few small pockets of trapped air in between them that helps in lowering conduction and convection. Moreover, the insulating fibers stop the trapped air to circulate within causing the convection process through the process.
The working process of insulation reduces the transfer of heat helping it to move in three different ways: convection, conduction, and radiation
