Underlays

There are many different types of underlays on todays market but below are the most common types and their uses:-

Foam Underlay

Uses:-

A standard underlay for laminate or engineered flooring for use in conjunction with a damp proof membrane when installing flooring on a concrete subfloor.  Foam is usually available in 2mm, 2.5mm or 3mm but other variations are available.

Combination Underlays

Uses:-

Combination underlays have built in damp proof membranes.  There are loads available and all have slightley different qualities but generally they do the same job.  For use on wooden and concrete subfloors. Most of them require you to tape the joints with waterproof tape but some have special sleeves that can be used.

Fibreboard Underlays

Uses:-

To help level slightly uneven subfloors, reduce 'foot fall' on flooring and to retain heat to your floor.  Fibreboard has no damp proofing qualities so you will need to use this in conjunction with a damp proof membrane when installing this on concrete subfloors.

Tuplex Underlay

Uses:-

Tuplex is a unique underlay that will act as a moisture barrier, sound resistant, sound insulator and has allows ventilation.  This product can be used for both wooden and concrete subfloors.

Timbermate Duratex

Uses:-

Timbermate Duratex is the traditional high density rubber underlay for use under laminate, solid timber and engineered wooden floors. Timbermate Duratex is particularly suited to wood-based suspended floors where moisture vapour is not an issue. Suitable for use over concrete or ground floor installations when combined with a suitable polythene sheet moisture barrier.

Timbermate Excel

Uses:-

Timbermate Excel is the original 'all in one' rubber underlay and has become the UK's premier underlay for wood and laminate floors. With a built-in Vapourstop barrier, Excel will protect against moisture; eliminating the need for polythene sheeting when used with Vapour Tape or Vapourstop sealing strip. With its proven high density, Timbermate Excel is ideal for domestic and contract installations.

Timbermate Silentfloor Gold

Uses:-

Timbermate Silentfloor Gold is the ultimate solution to noisy wood or laminate flooring. Silentfloor Gold offers the highest specification acoustic performance, highest density rubber underlay, with a built-in Vapourstop barrier. Silentfloor Gold will protect against moisture, eliminating the need for polythene sheeting when used with Vapour Tape or Vapourstop sealing strip. With its superior density it is ideal for domestic and contract installations where performance is the key, Silentfloor Gold beats all others.

Elastilon Underlay

Elastilon is the revolutional underlay for use with solid wood and engineered flooring.  Elastilon is, because of the heavy adhesive layer, a unique laying system and subfloor in one which pulls the floor segments together almost seamlessly. Wood is a complex material but this system solves many problems.

There are several different types of Elastilon:-

Basic:-

Elastilon Basic is the base onto which all other patented Elastilon systems have been grafted. It represents a completely new, revolutionary and extraordinarily spectacular laying system for parquet and strip floors. The fact that this product became world-famous almost overnight – as if the entire parquet sector, which is a merciless judge of quality, had been waiting for it – took even us by surprise.

Elastilon Basic, the product that makes this laying system possible, is intended for solid or layered flooring elements manufactured from stable types of wood with low coefficients of contraction and expansion. It can be used for wood types such as oak, afzelia, iroko, merbau and for laminate constructions, but not for the advanced two-layer parquet and not for beech wood in general, although it is suitable for the compressed beech strip boards manufactured by Junckers in Denmark.

Strong:-

Elastilon Strong is the strong brother of Elastilon Basic. This system is applied in the same manner, with the difference to Elastilon Basic lying exclusively in its higher density, while the adhesive layer is the same. Because of its smaller dimensions, and the low pressure distribution that this causes, it is used for two-layer parquet, narrow strips, patterns and quadrants (wooden tiles) and floors constructed from woods that are difficult to handle, i.e., almost all pinewood varieties.

Elastilon Strong can also be used in apartments and multi-storey buildings without the need for additional architectural or acoustic measures. In combination with many types of parquet, Elastilon Strong remains well within the required 10 dB criterion. In addition, Elastilon Strong can be used on under-floor heating in combination with solid wood or constructions.

Lock:-

Elastilon Lock differs from the previously mentioned types in that the adhesive layer is applied to both sides. It therefore only allows for minimal tolerances. It is applied in combination with very stable parquet systems, such as the advanced double-layer parquet or prefab pattern floors by, such as Cosmo, Italy, or the laminate flooring from Tilo in Austria. Together with under-floor heating, the parquet floor applied in this manner is a fully integrated part of the under-floor heating system, unlike glued systems, which are applied in spots. Impact noise is also reduced to a whisper.

Whereas nothing can go wrong with Elastilon Basic or Elastilon Strong, Elastilon Lock is not intended for the layman or bungler. A good idea is fine, as long as it is applied with practical intelligence. If, for example, you install a solid strip floor with a moisture percentage of 7% on Elastilon Lock, you might as well mark the date on your calendar where the fiasco will come to light: When the heating period has been pushed aside by some tropical summer days.

Sport:-

Elastilon Sport has the density of Elastilon Basic (30 kg/m³) or Elastilon Strong (50 kg/m³), from which it can only be distinguished by its thickness. Depending on the wishes of the building owner, it is available in thicknesses of 5 or 10 mm.

Compared to the traditional sub-constructions for sports floors, which are very expensive, highly labour intensive and difficult to handle, the big advantage of Elastilon Sport is the fact that a completely homogeneous elasticity can be obtained over the entire surface. This elasticity can be completely tailored to the desires or requirements of the architect, building owner or user, which is a clear added value and an even greater advantage.

The ballet hall at the University of Tilburg is a fine example of this: Here, the elasticity was not determined by the contractor, nor by the architect or the owner, but by the head ballet instructor.
