Question 1

What is Woolhouse underlay made from?

Accepted Answer

Woolhouse underlay is manufactured from a dense blend of natural wool fibres, mechanically bonded onto a durable eco-scrim backing.

This construction delivers:
High resilience under load
Consistent performance over time
A more stable alternative to lightweight synthetic underlays

Question 2

Is the product tested to recognised standards?

Accepted Answer

Yes. Woolhouse underlay has been tested in accordance with BS EN 14499:2015, the European standard for textile carpet underlays

Testing covers:
Thickness retention under static and dynamic loading
Compression performance and recovery
Structural integrity and resistance to cracking

The product meets the required criteria for general domestic use classification (GD/U)

Question 3

What performance can be expected under load?

Accepted Answer

Independent testing demonstrates:

Controlled thickness loss under static and dynamic loading
Retention of compression performance after repeated impact
No structural cracking under test conditions

This supports long-term use in typical residential and moderate traffic environments.

Question 4

What is meant by “IFR” in this product?

Accepted Answer

Woolhouse underlay is Inherently Flame Retardant (IFR) due to the natural properties of wool fibres.

This means:
No applied flame-retardant chemical treatments
No flammable secondary backings such as jute
Stable fire performance that does not degrade over time

Question 5

Is there acoustic performance data available?

Accepted Answer

Woolhouse underlay is designed with a dense fibre structure that contributes to impact sound reduction.
Third-party acoustic data is currently being validated under the Woolhouse brand.

Full certified results will be published as they become available.

Question 6

What are the key differences between product grades?

Accepted Answer

Core Comfort (42oz):
Balanced density
Suitable for general residential applications
Provides consistent support and insulation

Premium Durability (56oz):
Increased mass and density
Improved resistance to compression under traffic
Better suited to high-use areas such as circulation spaces and stairs

Question 7

Where is Woolhouse underlay suitable for use?

Accepted Answer

Suitable for:

Residential installations
Stairs, landings, and circulation areas
Projects requiring natural fibre specifications

It is designed for use beneath stretch-fitted carpet systems using standard installation methods.

Question 8

Does the product support long-term carpet performance?

Accepted Answer

Yes. Underlay plays a critical role in:

Reducing stress on carpet backing
Improving load distribution
Maintaining surface appearance over time

Testing under BS EN 14499 conditions shows stable performance under repeated loading scenarios

Question 9

What thickness and density consistency can be expected?

Accepted Answer

Testing shows:

Consistent thickness across samples
Controlled deviation within standard tolerances
Uniform behaviour under compression

This supports predictable installation and performance.

Question 10

Is the product suitable for specification in commercial projects?

Accepted Answer

Woolhouse underlay is classified for general domestic use (GD/U) under BS EN 14499

It may be suitable for light applications depending on project requirements, but specifiers should assess traffic levels and performance criteria accordingly.

Question 11

How is the product installed?

Accepted Answer

Installed using standard industry methods:

Gripper rods
Stretch fitting

No specialist installation requirements.
