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. "
