It also helps to absorb sound, reducing outdoor noise and providing a peaceful living space. But to reap the benefits of good insulation, you should use quality materials.

A Closer Look at Different Insulation Types

When insulating your home or building, you can choose from several types of insulation. The choice of insulation and insulation supplies depends on several things, such as the climate, the building materials, the design and your budget. Here are some of the most common types of insulation you would find in the London and Kent area:
  • Blanket: Batt and Roll Insulation: This is the most common type of insulation. The materials come in the form of an insulation roll and insulation boards or bats. The blanket rolls can be made of natural fibres, plastic fibres, fibreglass or mineral wool. This can be installed in ceilings, floors and lofts. The bats come in pre-cut sizes.
  • Insulating Concrete Forms (ICFs): These are hollow moulds in H-shaped structures with a centre cavity. The cavity is to be filled with reinforced concrete. They provide high thermal resistance up to R-20.
  • Rigid Foam or Foam Board Insulation: The insulation material comes in rigid boards or panels. They can be installed on both internal and external walls as wall sheathing. They can also be used for roofs, floors and lofts. They are moisture-resistant and provide thermal insulation.
  • Loose-Fill or Blown-in Insulation: The materials used for this type of insulation include cellulose, fibreglass and mineral wool. These are blown into wall cavities, ceilings, loft spaces and other areas. It’s perfect for small areas such as pipes and ductwork where other types of insulation wouldn’t work.
  • Radiant Barrier Insulation: This works by reflecting the heat instead of resisting it like other types of insulation. It doesn’t have its own R-value, so you can install it to cool your loft during summer. Radiant barriers such as aluminium foils along with backings such as cardboard, polyethene bubbles, plastic film or kraft paper are used in this insulation type.
  • Sprayed Foam or Foamed-in Place Insulation: With this type of insulation, liquid spray foam is sprayed or applied to unfinished or open surfaces of walls and floors. The liquid then expands to seal cracks and fill gaps. They can be installed in ceilings, floors, lofts and walls.
  • Structural Insulated Panels (SIPs): They are high-performance building panels. They contain two rigid board sheathing materials. In between them lies the insulating foam, which is generally made from extruded polystyrene (XPS), polystyrene (EPS) or polyurethane foam (PUR). They are covered with foils to protect them from moisture.
