5th Dimension FRESCOTTO Natural Fibre Carpet Underlay

£ 49.95 Product code: 4E15DFVDMN_410

Rolls or Sq Metres


5th Dimension is a new generation of carpet underlay. First there was felt underlay back in the early days of fitted carpets, then crumb rubber development in the 1950s was followed by production of sponge and waffle underlays.

For the last twenty or so years foam underlays have proven to be the most popular, however this new generation of carpet underlay claims a position as the most environmentally friendly of them all.

5th Dimension is a natural product with no harmful chemicals, vapours or volatile organic compounds (VOC's). Made from sustainably sourced wood fibres it is fully biodegradable, anti-allergenic and filters out over 95% of the dust that flows through it for a fresher environment.

5th Dimension FRESCOTTO is 8mm thick with a cubic density of 135kg sq. mtr which is far greater than many foam underlays. It has a tog value of 1.30 meaning that it can also be used over underfloor heating installations. An impressive sound impact reduction value of 31db makes this underlay a great all-rounder for use throughout the home.

How much underlay do I need?

Sometimes less than the amount of carpet needed. This is because when ordering a carpet you would normally choose the appropriate width available and there may be a little waste. But underlay is meant to be cut and joined, you can therefore order an amount closer to the actual size of the area.

How do I join underlay?

It is always best to tape joins to avoid movement, both during and after installation. A cloth single sided tape is best, but a budget priced tape will often suffice.

Which way up do I lay the underlay?

If there is a printed side, then this is usually laid uppermost. If there is no printing, but one side is relatively plain and the other side coloured, it is usually the plain side uppermost. If the underlay has a paper backing, this is laid uppermost.
