Frequently Asked Questions…

We are a national mail order company that only supply underlay direct to the public via mail order. We buy in bulk direct from the manufacturer and pass the savings on to you.

We take internet payments very seriously and after considering other companies we decided to use Paypal as it gives you, the customer, the peace of mind that you are in control of the payment and that you are insured by Paypal at no extra cost with regard to the transaction. It has to be the most secure and well respected ways of paying over the internet. You may of course by credit or debit card over the phone should you wish to do so.

The main deciding factor is feel underfoot, the heavier the weight of rubber waffle types of underlay, the thicker and softer it feels when walking upon it. The only exception to this is that the 150lb weight does not feel as soft as the 130lb weight.

This is not a hard and fast way of measuring carpet underlays, as suppliers give their own rating to an underlay and there is no standard applied.

Simply measure your rooms widest and longest point in metres, multiply the two which will then give you the m2. For example a room 3.5m x 4m has a m2 of 14m2.

As a very general rule of thumb it is around 80% of the carpet m2, but it is best to have it measured by a carpet fitter or store from where the carpet is to be purchased.

If you do not have underfloor heating, then a high tog underlay would be best as this will offer good insulation. Try Tredaire Dreamwalk.

The Tredaire Dreamwalk or Cloud 9 Cumulus as these have the best impact noise reduction properties of all the underlays we sell, Dreamwalk and Cumulus have a noise reduction of 46db and 43db. Please note that all acoustic sound insulation figures are based on impact sound and not airborne sound. Should you require an underlay that has airborne sound reduction properties, then have a look at the Combination underlays and in particular the Acoustic 1 and Kensington Deluxe Combination acoustic underlay.

An important function of floorcoverings is to improve the acoustic environment. Anyone who has moved into an empty house knows how harsh and noisy the rooms seem before the furnishings, and particularly the carpets, are installed. Floorcoverings are able to achieve the hushed environment, which is both comfortable to live with in practical terms, and also has become associated with luxury and taste. They do this by providing absorption and insulation of airborne noise and by reducing transmission of structure borne impact noise. Interfloor underlays considerably enhance the performance of floorcoverings, and their acoustic benefits should not be underestimated.

Sound travels through air as oscillating waves of compression and rarefaction. This is airborne sound . A freely suspended loudspeaker, for example, would achieve 100% airborne sound. However in practice all sound sources will be connected in one way or another, and to a greater or lesser degree, to the walls, floor or ceiling of a room. Sound also travels in these and is referred to as structure borne. Since one form is readily converted to the other, noise will not occur purely as one type.

Yes. Sound insulation is the ability of material to stop noise created in one room penetrating to another. This is achieved in two ways, only one of which is desirable. Firstly, sound may be reflected back into the room in which it was created: this echo effect is characteristic of hard non-porous surfaces. It leads to a noisy environment in which speech and music are not clear because the listener hears the original sound repeatedly, but separated by time intervals, and at reducing intensities. Secondly, the sound energy may be converted into another form such as, initially, mechanical movement of the receiving surface, and subsequently to heat This is sound absorption. Where present to a high degree, a quiet and clear environment in the room is achieved, and penetration into adjacent rooms is low. A good carpet/underlay combination can be very effective in achieving this.

Impact noise is produced when an object strikes the floor. Some of the impact energy is converted into noise, which is airborne directly back into the room. Whilst this in-room noise is actively being researched at present in conjunction with the producers of hardfloors such as laminate etc. Standard methods have not yet been adopted to measure it by the major national and international standard organisations. However, some of the impact energy is also transmitted to the floor structure mechanically, and is then transmitted as sound energy into adjacent rooms, particularly that below. Since the structure of the floor determines to what degree this effect can interfere with neighbours, the characteristics of the floor constructions in this respect are specified in building regulations. When a floorcovering is present, there is cushioning of impact so that the resultant noise transmitted through the floor is reduced. This is neither insulation nor absorption. It is reduction of the energy level at source. Underlays are important in this function, which is why we publish performance specifications for this property.

Yes, we supply by the square metre of all the underlays we stock.

Please check with your heating installer, but you are limited usually of having a combined tog rating of around 2.5 for the carpet and underlay with this type of heating, this does limit you to the types and styles of underlay. We would recommend that Duralay Heatflow or Heat King as these underlays have a tog value of 0.75 and 0.79 tog but still have a good feel underfoot. Please under no circumstances use PU underlays as the Tog values are far too high.

Crumb rubber is made from recycled car tyres that have been crumbed and then bonded together, it is very hard wearing and usually used in commercial applications were comfort is not as critical as wear. Blown rubber is a rubber material that is similar in looks to foam but made from a rubber based type material.

The Tredaire Seventh Heaven range and Cloud 9 range has the highest tog rating of all the underlays we sell and are therefore the best at heat insulation.

Tredaire Dreamwalk has the softess feel underfoot. It is 11mm thick and has a lifetime guarantee. It is a light weight underlay and this system has been voted number 1 in the carpet trade for some years now. Once you have used this product you will never go back to traditional carpet underlays
