Floor Insulation | Retrofitting floor insulation |

Floor insulation can save you approximately 10% on your heating bills and provide much more comfortable living conditions.

Although  floor insulation is best fitted at the time of building, it is often possible to retro-fit the insulation later.

There are several insulation types that can be fitted, depending on the type of floor and specific conditions in your home.

There are two main types of floors found in Irish homes:

  • suspended timber floor
  • solid concrete floor

Suspended timber floor insulation

There are three different types of under-floor insulation available for suspended timber floors:

  • foil insulation (works on reflection),
  • fibre insulation  (works by trapping air)
  • polystyrene insulation (works by trapping air)

Reflective Foil floor insulation

Reflective foil insulation

Foil insulation works as a convectional and radiant barrier. It has been difficult to get the best performance out of traditional foils due to building construction methods and strength of products, however newer more advanced types on the market offer some fantastic performance features.

The primary advantage of foil is that it acts as a complete vapour barrier stopping rising dampness coming into the home and they are also great for working in tighter areas.

Foils are installed in blanket format making them quick and easy to install.

Polyester Fibre floor insulation

Polyester fibre insulation

Fibre forms of insulation work in much the same way as your clothes; the thicker your jacket the warmer you are. The most popular form of fibre under-floor insulation is polyester.

The key advantage of fibre types of insulation is that they allow the floor to ‘breathe’ while still offering excellent thermal qualities.Precut products are available for fitting between your joists or alternatively blanket format is also available for attaching underneath the joists.

They are not particularly suitable where you have a rising dampness problem but they offer very good performance and very long life.

Polystyrene Panel floor insulation

Polystyrene insulation

Polystyrene under-floor insulation is a well known product on the market. There are several different forms of polystyrene products available on the market, each with a small differences.

Polystyrene is great for dampening sound reverberation in wooden floor boards and also acts as a partial vapour barrier. Available in wide variety of widths, it is always installed between your joists and each piece is cut to size and friction fitted up into place.

Some people reduce cold drafts through the floor boards by blocking air vents on outside walls. Blocking the air vents on outside walls is not a good idea as this air circulating under your home stops your floorboards from becoming damp and rotten and prevents the build up of undesirable gasses under your floor.

Solid  Concrete Floor Insulation

Although insulating an existing solid floor can be messy and disruptive, it is worth considering as it adds significantly to the comfort of your home.

As most preparatory work will be done while installing the insulation, you may also consider installing underfloor heating at the same time.
