Nuaire advise on curing condensation – for good!

It’s at this time of year that poor ventilation is really obvious.  Streaming windows, lots of humidity and, for those that suffer the most, this could mean mould and dust mites in the home.

There are various ways to ventilate according to building regulations, from extract fans and passive stack to mechanical extract and MVHR (heat recovery). Yet, often overlooked is a ventilation strategy that sits under ‘alternative methods of ventilation’ - ‘PIV’ or Positive Input Ventilation.

PIV is the process in which fresh air is supplied by a fan located in the loft area into the upstairs landing area of a building, where air is tempered using the heat that naturally accumulates at the top of a house. It is then filtered and gently pushed into the home, causing positive pressurisation. By continuously supplying fresh, filtered and warm air this method displaces the damp, stale air that causes condensation, which escapes via natural leakage points. As a result, indoor air quality, and health, is improved.

The same PIV principle can also be applied in apartments and flats where a wall mounted unit delivers the air into a central corridor.

PIV was developed by Nuaire in the 1970s in conjunction with the North Eastern Gas Board, which was seeking a low cost solution to clear condensation and humidity caused by sealed up chimneys and modern central heating systems.

Wendy Thomas, Residential Product Manager at Nuaire, said: “People do not appreciate that bathing, cooking, washing and drying clothes creates up to four pints of moisture in the home per person per day. There’s no way to see this moisture until it clings and condenses on to colder surfaces – such as windows. This moisture can encourage mould and mites, which can trigger allergic conditions, such as eczema, conjunctivitis, rhinitis and even asthma.

“Positive Input Ventilation systems are proven to be quiet, energy efficient and shown to significantly improve indoor air quality with incoming air that is controlled and filtered.”

By filtering the air that enters the home, the process can reduce the overall maintenance costs of a property by protecting the fabrics and materials in a home. PIV is also a known method that can help reduce high levels of Radon gas within homes in affected areas.

Positive Input Ventilation is ideally suited to repairs and maintenance, yet is also gaining popularity in new build homes. So, if you are dealing with steaming windows, mould, radon gas or just considering all ventilation strategies, don’t forget about PIV.

Nuaire Unveils The Next Step In Carbon Filtration

As many as 40,000 deaths each year are being caused by exposure to air pollution, and rising Nitrogen Dioxide (NO2) and Particular Matter (PM10 and PM2.5) from traffic fumes are the major culprit.

Nuaire unveils a new range of carbon filters to help protect homeowners from rising air pollution levels in our traffic-congested towns and cities. The IAQBOX takes air purification to the next level, offering the highest levels of filtration and the lowest resistance of any system on the market. And while the range sets a new benchmark, it offers competitive pricing.

IAQBOX removes 99.5% of NO2 from the air, as verified by the BRE, making it the most effective system available. IAQBOX also removes chemicals produced through industrial processes and burning fossil fuels, as well as filtering out strong odours.

Nuaire’s carbon filter range has optional PM10 and PM2.5 pre-filters that ensure up to 95% of harmful particulate matter is removed from the intake air, with the G4 filters inside Nuaire’s MVHR system acting as a third barrier to airborne particles. This pre-filtering technology not only safeguards the health of the homeowner, but prevents build-up of harmful materials inside the MVHR system so it operates more effectively for longer.

Uniquely, the carbon ‘media’ is held in one block rather than a row of individual filters, which makes removal and replacement quicker and easier. Nuaire can guarantee a four-year lifespan for its filters, so maintenance is minimal.

With marked improvements in current levels of resistance and unique features, Nuaire aims to make this life-saving technology easier to specify. IAQBOX is available in two sizes for greater flexibility.

IAQBOX-D Double is an industry first. With a greater surface area to remove even more NO2, its double-width size reduces overall air resistance to the lowest levels of any carbon filter on the market. With resistance dramatically lowered, the fan can run at a lower speed which makes it quieter.

IAQBOX Double features a spigot configuration of ‘one-in, two-out’ that not only helps reduce pressure drop, but also acts as a plenum, cutting out an additional duct connection. In the same way, it acts as an attenuator, reducing in-duct noise.

The standard IAQBOX-S Single unit is both smaller and lighter for smaller homes. IAQBOX is mounted in the ceiling void. It measures just 170mm in depth, meaning a saving in valuable void space for apartments.

Nuaire Ductmaster Thermal Shortlisted for a Housebuilder Product Award

Nuaire’s innovative and time-saving thermal ducting solution, ‘Ductmaster Thermal’, has been recognised by the judging panel at the Housebuilder Product Awards 2014, to the delight of the company.

Nuaire introducted Ductmaster Thermal to support housebuilders in meeting building regulations and to help them save time and costs on site. The innovative all-in-one system solves the issue of insulating ducting through un-heated spaces, an area highlighted by the NHBC guidance document.

Residential Manager Stephen Smith explained: “When installing MVHR systems, a great deal of time is spent on the labour-intensive practice of insulating PVC pipes, and in many cases the processes used to insulate ducting don’t actually confirm with building regulations. Unlike other insulated materials that wrap around the PVC pipe, Ductmaster Thermal is an all-in-one system where the Insulation used for thermal protection is the duct itself.  It is the only all-in-one solution that is fully compliant with building regulations.”

Ductmaster Thermal features a unique clamping mechanism that forms an air-tight seal, eliminating the risk of condensation forming in the duct. With no need for any sealant or tape, installation is simple and quick, helping to lower labour costs for installation on site.  The new product has recently achieved LABC (Local Authority Building Control) Certification for both round and rectangular ranges, meaning that Ductmaster Thermal is approved for use and backed by the LABC on any of their new build and refurbishment projects.

The Housebuilder Product Award nomination further confirms the popularity of the thermal ducting system.  Stephen Smith said: “Being shortlisted for such a competitive industry award is a highlight for Nuaire’s Residential team, proving that our efforts to design a system that saves time and costs for installers whilst meeting building regulations have been recognised by some of the key players in the home building industry. We are in good company in the Building Services Category and wish our fellow nominees the best of luck at the awards lunch in July.”

Sean Flaherty of Bullock Construction Ducting Comment

(Sean Flaherty, Bullock Construction)

Feedback from contractors and installers has been extremely positive. Sean Flaherty, Project Manager for Bullock Construction gave his views on the new ducting system as part of the awards entry, commenting in particular on the increased manoeuvrability of the ultra-light weight ducting. “The Nuaire Ductmaster Thermal is more user-friendly for the operatives to install. It is lighter; the clips come with the ducting and are easy to fix, and the ducting is much easier to use. The old method was time-consuming and much heavier for the installers. Now they can use a step ladder for access which is much easier.”

Bullock Construction MVHR installer Miles also commented: “Normal ducting takes us two to three days to install, but with the Nuaire Ductmaster Thermal it takes half a day to a day, maximum. For me, the best feature is how lightweight it is compared with the old plastic types. It’s much easier going up into the loft and easier to move around when you’re on a step ladder.”

Preventing condensation is better than the cure say ventilation designers, Nuaire

The dangers of damp and mould spores caused by condensation are very real, and as winter approaches social housing tenants living in poorly ventilated homes will be at risk of developing or worsening a range of allergies, from asthma to rhinitis. Faced with energy price hikes and more severe winter weather, tenants are less likely to open windows and dry clothes outside and so the damage caused by condensation remains.

As autumn approaches and the temperature drops, many Registered Social Landlords will start preparing for the onslaught of tenant complaints about damp walls, condensation on windows and the appearance of black mould on fabric, clothing and wallpaper.

Condensation dampness affects both new and older properties and is much more common than you might imagine. Excess moisture is produced simply by breathing and by everyday activities like bathing, cooking, washing and drying our clothes.

An average family can produce up to four pints of water per day and this moisture is absorbed into the air where it migrates through the home and condenses on cool surfaces such as windows, mirrors, wall tiles and furniture.  This humid environment is the ideal condition for mould spores to germinate and grow, and for dust mites to breed.  These allergens can aggravate asthma and trigger allergic symptoms such as rhinitis and eczema, so while your property may be subjected to cosmetic damage caused by excess humidity, the health and wellbeing of your tenants will also be at risk. In short, condensation dampness is bad news for all concerned.

For many RSLs, this problem comes around every year between autumn and spring, bringing with it visits from surveyors and damp assessors, and costly repairs to the building fabric and decoration.  Many will try to encourage their tenants to adopt lifestyle changes to lower the level of humidity in the property: opening windows and closing doors in moisture-producing rooms, keeping the property warm to reduce cold spots, and not drying clothes inside.  In reality, as a result of fuel poverty and more extreme weather, it is often difficult to enforce these changes and when outside temperatures plummet any activities that result in a loss of heat and increased fuel bills are quickly abandoned.   

So what’s the solution?  Trawling the internet for advice on tackling condensation will uncover a plethora of so-called cures, but be wary: many of these are simply short-term solutions that will mask or target only the cosmetic appearance of mould without actually dealing with the root of the problem.  Anti-mould paint, dehumidifiers, cavity wall and loft insulation, draught-proofing and installing double glazing are just some of steps suggested by retailers and suppliers.  Some are extremely costly, others are effective for tackling penetrating damp, but none of them will solve the condensation issue.  It’s a matter of adequate ventilation.

For properties badly affected by condensation dampness, the most effective solution is a whole-home ventilation strategy called Positive Input Ventilation, sometimes referred to as Positive Pressurisation or PIV.  Ventilation manufacturer, Nuaire invented the technology over 40 years ago in conjunction with the North Eastern Gas Board which sought a low-cost solution to clear condensation and humidity
caused by sealed up chimneys and modern central heating systems. Today, PIV is the most popular method of whole home ventilation in the UK, being simple to install and still providing the only known cure for condensation dampness and the associated health issues caused by dust mites, mould spores and other indoor pollutants.

The PIV process involves drawing fresh air from outside into a fan located in the loft area. The air is filtered, tempered using the heat that naturally accumulates at the top of the house, and then gently pushed into the home causing positive pressurisation.  By continuously supplying fresh, filtered air through the home, the moisture-laden stale air is forced out through the natural leakage points.  As a result, the humidity is drastically reduced and the allergens are removed from the air creating a fresh and healthy indoor environment for tenants.

Quiet and energy-efficient in their operation, Positive Input Ventilation systems can reduce the overall maintenance costs of a property by protecting the fabric and materials in the home and preventing the build-up of tell-tale signs that often trigger tenant complaints. This strategy is extremely cost effective and quick to install compared with other ventilation strategies such as installing individual extract fans in all wet rooms. This makes PIV ideally suited to repairs and maintenance projects, yet it is gaining popularity in new build homes.

Importance of Indoor Air Quality in Energy-Efficient Homes

When it comes to evidence of how indoor air pollutants can affect our health, we’re certainly not short of compelling research. The report by the Royal College of Physicians, published in February 2016, highlighted to risks posed by poor indoor air quality, and put the NHS at the forefront of the debate on IAQ. This report, coupled with research from NICE and the World Health Organisation on the sources and effects of indoor air pollutants, gives weight to the arguments put forward by the ventilation industry that IAQ must become a greater focus by the government and within Building Regulations and for the Government.

A further report by Professor Awbi: ‘The Future of Indoor Air Quality in UK Homes and its Impact on Health’, argues that building regulations aren’t taking into account the impact of improved air-tightness and increased energy-efficiency on indoor air quality and people’s health.

Prof. Awbi recommends that there should be a legal requirement for new homes, and guidance for retrofitted homes, to have an air exchange rate of at least 0.5/hour to protect our health. Continuous mechanical ventilation is, he says, the most effective way of hitting these rates whilst saving energy. So for new build homes, MVHR is the key.

But what about the millions of existing homes across the UK, especially those in areas of high air pollution? What retrofit ventilation products will help? We see Positive Input Ventilation, a technology invented by Nuaire in the 1970s, as the more effective retrofit solution.

Nuaire’s Solutions For Improving IAQ

The ‘Fabric First’ approach to building new homes helps to achieve sustainability, high thermal performance and cost-efficiency without the need for solar technologies. These air-tight construction methods can result in poor indoor air quality as condensation and indoor pollutants remain trapped inside the home.

Adequate ventilation is key to the ‘fabric first’ approach. MVHR is still the most effective ventilation strategy for homes built with high thermal values and high air-tightness.  Our range of low-energy systems include models that are designed to fit around the size and use of the new build property. From low-profile systems designed to fit into apartments shallow ceiling voids, up to our largest units for properties with up to six wet rooms.

By running continuously, an MVHR system will extract stale air which has been contaminated by indoor pollutants whilst filtering out pollen, pollutants and dust particles from the incoming air, thus ensuring good indoor air quality.

Changes to Building Regulations Part L, which focus on conservation of fuel and power, have put an even greater focus on cutting carbon usage through improving the fabric energy-efficiency of new build homes. This is good news for the environment and for homeowners who will benefit from the 6% improvement on carbon reduction from the 2010 regulations; however, the regulatory changes don’t include advice on ensuring good indoor air quality. In an age where many homeowners filter their tap water through fear of drinking chemicals, many are unaware of the chemicals and pollutants they breathe in on a daily basis in stale air that is trapped inside the home.

At Nuaire, we are going a step further with the launch of our new Q-Aire Carbon Filter. It is specifically designed for homes in urban areas and it supports the MVHR system by ensuring the air is properly filtered before it enters the property. This measure protects the homeowner from damaging air pollutants such as carbon dioxide and nitrogen dioxide.

The Carbon Filter is suitable for specification and allows contractors to meet planning obligations when building homes and apartments in areas with high air pollution. We’ve designed it to be easy to install but also easy for the homeowner to maintain, because, as we know, effective maintenance is the only way to ensure the MVHR system does its job properly.  The filters are built with innovative Colourcell ™ technology, which provides a visual indicator of when the filters need to be changed: a simple change of colour. 

What Can Go Wrong If the Wrong System Is Specified?

Planning and installation are the key to an effectively operating MVHR system. Manufacturers like Nuaire offer a great deal of advice and support to consultants at the planning stage, to ensure that the right system is specified. However, a recent trend in apartment building is for MVHR systems to be selected based on the size of the cupboard or wall space, not on the requirements of the apartment. Added to this, the MVHR systems are then run at top speeds to tackle the common problem of over-heating, problematic in areas of high air or noise pollution where openable windows are ruled out by planning restrictions. A unit that is too small to ventilate the size of property, also run at maximum speeds to tackle over-heating, will no-doubt be noisy.

Nuaire has designed a solution to this problem with its Q-Aire 1Z, a unique all-in-one acoustic enclosure that removes breakout noise and vibration. This solution allows contractors to meet the strict noise requirements set out by CIBSE guidelines.

Positive Input Ventilation – Drimaster-Eco Range

As well as being able to provide more traditional mechanical ventilation solutions, Nuaire is able to offer an alternative and equally robust approach when heat recovery is not required. Our alternative approach is a strategy called is Positive Input Ventilation (PIV) which was invented by Nuaire back in the 1970s. It’s now installed in over 1 million UK homes as a low-energy, low cost solution to combat condensation and indoor pollutants, and it’s suitability to new build ventilation is now being recognised.

This strategy works by providing a continuous supply of fresh, filtered air into the house through a fan mounted in the loft. The gently warmed input air enters the home through a ceiling diffuser, creating a positive pressure effect that reduces humidity levels and forces out air pollutants, improving indoor air quality and helping to minimise the entry of harmful Radon gas.

PIV will work without the need for any trickle ventilators down to an air permeability of 3m3h/m2 ensuring an additional saving for the homeowner.

The Drimaster-Eco range includes three models. A unique feature is the sleek, circular ceiling diffuser which houses the system controls, allowing adjustments and commissioning to be carried out from the hallway without having to enter the loft.

Added controllability comes from the remote sensors and controls that instruct the PIV system to respond accordingly to changing humidity and CO2 levels. This controllability improves indoor air quality and helps save energy. Nuaire is excited to be the first manufacturer to full demand-control through these energy-saving controls and sensors. This development marks an exciting change of direction for PIV.

Unlike other PIV systems on the market, the Drimaster-Eco range offers twice as much filter area so the filters are more effective for longer. Small and light, the new unit offers an extended duct length to overcome installation restrictions, and can be hung at the right height to maximise heat gains within the loft space.

The Drimaster-Eco-Heat features an integral heater which is sited uniquely between the flexible duct and the diffuser. The unique heater position offers the same performance whilst using up to 20% less energy than the competition. This means lower running and life cycle costs.
