Manufactured using user-friendly
non-irritant, non-itch material that is free from floating fibres or dust, avoiding the skin irritation and respiratory problems normally associated with other forms of glass wool insulation.
Provides good acoustic properties to help keep your environment quiet and free from noise pollution.
Non-Itch Loft and General Purpose Roll ... , Safer, Cleaner, Greener Insulation
Overview - Non-Itch Rolls
Even more exciting for those who are aware of the need to protect and conserve our environment, is the fact that no less than some 85% of the material used in the production of this insulation is derived from recycled plastic bottles!
This not only has a positive effect in reducing land fill problems now but also in the future as the material is, and remains, 100% recyclable.
It is also 100% non-allergenic, 100% non-irritant and 100% free from floating fibres.
Known as Non-Itch, this material is installed and performs in exactly the same way as traditional insulation but, in contrast with mineral fibre, which requires a large amount of energy in its production, its manufacture creates a very low carbon footprint as the expended energy is very low.
For every 1 ton of plastic bottles used in the manufacture of Non-Itch Loft Insulation, 1.5 tons of carbon emissions are prevented from polluting the atmosphere; this is even before the product is installed, at which point it continues to reduce the carbon footprint and benefit the environment.
This fully tested and certified insulation (UKAS Cert. 1145 - 738 : Agrément Nos. BPD 07-217/8, Patent Pending) offers specifiers, housebuilders & contractors the opportunity to install insulation into lofts, partitions and timber frame buildings without any of the drawbacks normally experienced with glass or mineral wools.
Non-Itch Insulation is supplied in easy to handle rolls in thicknesses of 100, 150, 170 & 200mm. Trade packs of 3 rolls are available for use between joists spaced 380mm apart and packs of 2 for those spaced 570mm apart
Non-Itch Insulation is supplied in easy to handle rolls designed to be installed in exactly the same way as mineral fibre or fibre glass and provides the same thermal conductivity
Non-Itch Loft Roll
Non-Itch Insulation is made from user-friendly
non-irritant, non-itch material that is free from floating fibres or dust and so avoids skin irritation and respiratory problems normally associated with other forms of insulation.
Non-Itch will not deteriorate over time and will not be affected by mould, mildew or rot.
Non-Itch is also resistant to vermin and insect attack.
Non-itch is certified by UKSD and is DBA Agrément certified.
Other features include:
Totally safe and easy to install with no protective clothing required.
Ensures a safe indoor air quality.
Provides good acoustic properties to help keep your home or commercial environment quiet and free from noise pollution.
Non-Itch is unaffected by water.
Long term stability and durability 50 years +
Every one tonne of plastic bottles recycled for the manufacture of Non-Itch saves one and a half tonnes of carbon emissions into our atmosphere and so has a dramatic positive impact in our efforts to save our planet.
Ideal for eco builds
Fully recyclable and uses recycled material in its production.

YBS Non-Itch Insulation Roll - Properties
The table below shows the U-values achieved using Non-Itch laid in the roof void.
U-values are based on the first layer of insulation laid between the joists, and the remaining thickness installed as a second layer, cross-laid over the joists to reduce cold bridging ...

Application
For safety, work from suitable “crawling boards”spanning four joists.
Start from the eaves ensuring the wall plate is covered and work towards the centre of the loft, placing Non-Itch between the joists (on top of any existing insulation in place).
Butt joint where necessary. When space along the joists is filled, the end of the roll can be turned back to start an extra layer of insulation or may be cut to size.
Layer insulation to the required thickness ensuring the ceiling beneath is completely covered except directly under the water tank.
Where the depth of previously installed insulation has reached the top of the joists, extra heat saving is gained by cross layering (at right angles to joists) with Non-Itch.
Insulate and draught seal the loft hatch.
Why Non-Itch Loft Roll Insulation (extract from Professional Builder Magazine)
Some people worry about creating damp
problems caused by insulating floor voids and
it is true that you must be careful not to block
any airbricks but, provided you keep the
airbricks clear to maintain cross ventilation
and there are gaps in the sleeper walls, there is
no risk to the timbers.
The dew point is on the cold side of the insulation and not against the
timber, so any moisture on the cold side is
cleared by ventilation in the normal way
The fact that YBS Insulation has changed the name of Ecowool to Non Itch is largely due to
the fact that its user
friendliness is even more of a selling point in the trade than the fact that it is made from 85% recycled plastic drinks bottles.
You can see their point – in the old days of itchy glass wool you would never
volunteer for the job of topping up insulation.
Yet this job is crying out to be done in
so many homes. There is also a massive
opportunity for improving comfort levels
and reducing heating bills by insulating the
underside of suspended timber floors.
I bit the bullet and did my own house some
years ago and it transformed the thermal
performance of the property overnight,
making it infinitely more comfortable. The
payback period for this job is so short that
nobody could argue against it on economic
terms, but the instant return is from the
way it improves the thermal comfort in
ground floor rooms.
Plumbers and electricians, who have to
work under floor voids, you might not
relish extending the job by adding
insulation, but once you are down there it
really takes very little time, and the
customer will sing your praises from the
rooftops for giving them warm feet.
It is a
nonsense that we insulate the rest of the
house, and spend money on double glazing,
whilst still leaving just 22mm of timber and
a bit of carpet (if your lucky) between our
feet and the outside temperature.
Having done the heating and rewire in
this Edwardian house we knew that the
floor voids had plenty of room to crawl
around in. Before the floorboards were
fixed back down I took a dive underneath with a few rolls of 150mm Non Itch.
The 360mm wide rolls fitted snugly in between the timber joists, but I stapled
the polythene bags across in places just
to prevent any future sag or fallout.
Non Itch is not too easy to cut with a
Stanley knife, you really need a pair of
wallpaper scissors. The rolls are laminated
to make up thickness, so it is easy to pull
it apart and feed a thinner section
through first. Once this is in place
another section can be dragged through
on top of it. It is a two-man job but
between us we managed to do the whole
of the ground floor in three hours, and I
didn’t scratch or cough once. "
