When insulating your home, there are several common insulation materials to choose from with each offering different benefits. Every type of insulation have pros and cons and will have varying environmental benefits that should be considered. So what are the key contenders?
Blanket Insulation Material
The most common type of insulation which is used in the home is blanket insulation which usually comes in rolls with a foil backing. The material normally used is glass wool which is made from recycled bottles which gives the material a good environmental rating.
Glass wool insulation is one of the easiest materials to install and is the most cost effective.
RockWool Insulation Material
Rock mineral wool insulation is a more solid material than glass wool so is suitable for situations where the material may be compressed. Mineral wool can be obtained in rolls and comes in varying thicknesses and widths.
Rock mineral wool is a very effective fire safety measure as it is resilient to heat and fire.
Sheet loft Insulation Material
Sheet loft insulation is a common insulation material and comes in sheets. It is usually used to insulate the sloping side of the roof inside a loft.
This type of insulation can be more expensive and is energy intensive to manufacture but has a high insulation value.
Loose-Fill Insulation material
One of the more common forms of insulation is loose-fill and blown-in cavity wall insulation. Loose-fill takes the form of small particles that form a material that can conform to any space without disturbing structures.
The most commonly used material for this type of insulation is cellulose, fibreglass and mineral rock wool which are all produced from recycled material. Loose-fill will typically be installed in wall cavities and attics/lofts and is installed via a pipe.
Cavity and Solid Wall Insulation
The National Insulation Association estimates that 33% of a property’s heat is lost through the walls. Insulating your walls against this heat loss can make your property much more energy efficient.
Most modern homes in the UK are built with cavity walls, that is, an inner and an outer wall with a space between them, which are designed to stop rainwater reaching the inside of the property. These cavities also allow heat to escape, however. It is possible to prevent heat from escaping by filling the gap between these two layers.
Cavity wall insulation is installed by drilling a small hole (around the size of a bottle cap) in the property’s outer wall and using a pump to fill the gaps with a polyurethane insulating foam. Though installing this is not a DIY job and must normally be done by professionals, it is quick to do and relatively inexpensive.
It is also possible to install solid wall insulation, which can be fitted either internally or externally, with decorative coatings. This method of insulating walls is significantly more expensive and disruptive than cavity insulation, as it can sometimes require substantial building and decorating work.
Spray Foam Insulation Material
Spray foam is also a common insulation and works in a similar way with liquid foam being poured or injected into place into wall cavities making it very versatile.
Spray foam is installed using a foaming agent and will expand and become solid as the mixture cures. Slow curing foams are available which will flow around any obstructions inside the wall cavity before hardening.
