The vloerisolatie of a building can be carried out in a large amount of different ways. A handful of these methods include roof, loft, cavity wall and external wall. One of the very common and indeed effective types of home insulation is carried out on a floor... or more to the stage, beneath it.

There are numerous distinct types of floor isolation including (but not limited to) foil, fiber and polystyrene sorts. Each offers different advantages and disadvantages in performance, installation and cost. This article that follows will provide a quick breakdown of each insulation system in the context of floor insulation.

Foil Floor Insulation 
Foil floor insulation can in certain ways be described as a very tricky system to install in a home. Acting as an immediate barrier by reflecting heat back into a building (e.g. from an underfloor heating system), foil insulation will also restrict airflow and the passage of moisture because tight fit to floorboards etc. Nevertheless, despite its inherent benefits and recent progressions in technology, foil floor insulation doesn't offer particularly spectacular U-value performance.

Fiber Based Floor Insulation 
Fiber insulation (such as polyester, rock wool and steel wool) is pretty straightforward in its use in just a home. Imagine a huge blanket being cast over a building's floor and you're halfway there. Unlike foil floor insulation, the fit isn't tight and therefore moisture can seep through into a building. As this is a side advantage of floor insulation however, it's not just a deal breaker.

Polystyrene Floor Insulation 
Polystyrene insulation has been rapidly gaining in popularity lately and among its key applications is underfloor. Much like a takeaway coffee cup, polystyrene works due to trapped air bubbles within the material that restricts the increasing loss of heat in just a building. Sold in beads and foam, it's most commonly available as sheets which are simple to cut and install. Other advantages include it being lightweight, resistant to moisture, having a very long lifespan and offering sound proofing qualities which make it very attractive using builds.
