The right loft insulation creates an air barrier within your roof space. Dependent on the insulation product it can be applied along your loft or attic floor between the horizontal beams, also known as joists or it can be applied between the angled beams, known as the rafters, that offer the roof structural support.

The loft insulation generally depends on the type of roof present in your home. For example, sloping roofs are quite straight forward, and there are plenty of insulation options suitable for this roof structure.

Why is loft insulation Important?

 

Why is loft insulation Important

 

Loft insulation is the most practical & cost-effective way to make your home more energy-efficient and reduce your energy costs. If you are renovating your home or building a new one, you need to have a proper loft insulation done according to new Building Regulations.

The right loft insulation is important as most homes lose a considerable amount of the heat through their roof due to poor / insufficient insulation, resulting in higher energy bills, colder nights, condensation and drafts.

Another important aspect is that Loft Insulation helps in controlling and regulating the temperature of a property. This means the building will be cooler in summers and warmer when it is cold outside. This leads to improved comfort for anyone inside the property, a healthier place to live/work and decrease in energy consumption.

One of the main reason people generally don’t insulate their lofts is that they want to use it as storage. Traditional insulation materials require a higher thickness than the joists of the attic, making it difficult to use the area after the insulation. But with recent technological advancement new insulation techniques such as spray foam insulation, can quickly resolve issues like these, as spray foam insulation requires much less thickness to provide similar insulation values and thermal conductivity, according to the Which.co.uk

3 Popular Ways in the UK on How to insulate a loft?

 When it comes to insulating your loft, there are a few different methods used by installers. We have outlined 3 of the most popular methods that have been used by homeowners across the UK for the last few years.

  • Fibreglass Loft Insulation – As I’m sure you’ve heard; this is generally used for the structures that are open and easy to access. Fibreglass rolls or batts are laid down along the floor or in the rafters of the loft. In order to be completely effective, fiberglass insulation must be cut carefully around obstacles such as power sockets. Which can be incredibly time-consuming. (this insulation method has become outdated and can start sagging as time passes. When installing fiberglass be sure to wear protective wear to protect yourself from the “silver” released from fiberglass. This can cause skin irritation.)
  • Cellulose Loft Insulation – cellulose loft insulation is mostly made of shredded papers which are blown over the surface in the loft area to be insulated. Cellulose insulation in installed into your loft using an insulation blower. The fibers flow through a long hose and are blown / sprayed into your loft space. The blown cellulose is prone to create dust that is blown into the holes or inadequate seals around fixtures, this can be a health hazard.
  • Spray Foam Insulation – Spray foam has changed the dynamics of the home insulation industry. It has revolutionized how loft insulation is done for both residential and commercial properties. Icynene spray foam is a BBA, BDA, KIWA, and Energy Saving Trust approved, product. Icynene spray foam insulation, after application between the rafters, expands 100 times, creating an air-tight seal. This Air barrier seals any cracks on the surface, thereby reducing further condensation in your loft and eliminating mould growth as well. Air seal also works in trapping the heat for long inside your home, which in turn keeps your house warm for longer duration lowering your energy cost.
