• Condensation Control

  Top Joints Dry Lining can assist in treatment of and protection from condensation in your building or dwelling.

  Condensation is becoming one of the commonest causes of dampness in buildings and is nearly always associated with black mould growth (Aspergillus Niger)

  The problem arises because of high relative humidities, a lack of natural ventillation and, in most cases, cold external walls. Sometimes it's possible to reduce humidities by regulating activites like drying clothes indoors. Ventillation can be provided by trickle vents and so on but these are usually ineffective and unpopular due to perceived heat losses and cold drafts. Walls can be insulated but not without relatively major distubance to occupants. Because of these factors a new approach to providing energy effecient humidity control was needed as this has been provided through the concept of "positive input ventillation".
  
  Top Joints Dry Lining can advise on the most effecient and least invasive condensation control solution and our technical team are able to offer a full diagnosis and installation service and will ensure you get the system best suited to your property.

  Homevent Loft Unit

• 
  

  Positive Input Ventilation System....an energy efficient method of displacing stale contaminated air and replacing it with fresh filtered air. Fresh air is drawn from outside via the loft space through a filter on the unit and delivered into a central location in your home.

• 
  This displaces vapour-laden air, which lowers humidity levels, cures condensation and eradicates mould.

  • Whole House Ventilation
  • Streaming Windows - Stopped
  • Enhanced Heat Distribution

  
  

  The Wykamol Homevent unit runs continuously except when the loft temperature rises above 25°C when the unit will switch off, as this hot incoming air would be uncomfortable.When the air temperature falls below 25°C, the unit will switch back on.

• 
  To help keep your home condensation free:

  • Do not dry clothes over any radiatiors • Vent your tumble dryer outside
  • Try not to use Paraffin/calour gas type heating

  To improve the comfort of the incoming air there is an integral “intelligent low temperature” comfort heater* in the unit.

• 
  *This feature employs a sensor, which monitors the incoming air temperature and ensures that when the external temperature drops, the incoming air temperature does not fall below 10ºC.

• 
  Controlled by an enable / disable switch located in a convenient position within the property, this energy-efficient heater uses around 7 pence per day. However this figure can be further reduced with prudent use, by disabling when the house is empty or other non-critical times - see below.

  Loft Mounted Unit EnviroVent

• Back to Top

• 

  The EnviroVent loft mounted unit is a sophisticated whole home ventilation and condensation control unit for homes with a loft space. The unit gently ventilates the home from a central position on the landing in a house or the central hallway in a bungalow to transform a stagnant, stale atmosphere into a fresh, healthy, condensation free environment.
  
  
  Removes musty odours
  

  
  
  Benefits asthma sufferers
  

  
  
  Stops streaming windows
  

  
  Health benefits
  
  Moisture-laden air is diluted, displaced and replaced with clean, tempered and filtered air. This eliminates or reduces surface condensation, which causes mould growth, providing a significant improvement in the health of asthma sufferers and general indoor air quality.

• Energy efficiency
  

• 

• The unit takes maximum advantage of the benefits of solar gain from within the loft space - the natural accumulation of heat from the sun on bright days. Temperatures in the loft space are on average 3°C higher than outside, which results in a relative saving of around 150 Watts per day in an average modern family home. This equates to approximately 10% of annual heating costs.

  KHRV150 Heat Recovery Room Ventilator Back to Top An energy efficient continuous heat recovery system for healthy air in kitchens, bathrooms, utility rooms, living rooms, lavatories, washrooms, conservatories, offices and bedrooms. How it works The KHRV150 Heat Recovery Room Ventilators provide a continuous air change, replacing stale moisture-laden unhealthy air with filtered, fresh, warmed air from outside the dwelling. The continuous controlling of Relative Humidity levels ensures that conditions will not exist in which condensation or mould growth problems can develop and thrive. Why Specifiy a KHRV150? Ventilation is necessary to maintain a healthy and comfortable internal environment and to rapidly remove pollutants such as moisture, volatile organic compounds (VOC’s), allergens such as dust, oxides of nitrogen, carbon monoxide, carbon dioxide, tobacco smoke and unpleasant odours. Moisture is generally assumed to be the most significant of these pollutants because of the high rates of generation from cooking, bathing, washing, drying etc and the consequential condensation and mould growth problems. It follows that if the ventilation strategy is based on controlling this principle pollutant by heat recovery input / extract ventilation then logically the other indoor pollutants will also be adequately controlled. Stale air, and air which is hot or humid, should be replaced at a reasonable rate. Good ventilation means providing a balance between energy efficient and healthy indoor air best summed up by the catchphrase ‘Build tight – ventilate right’. The fresh air supply rate should not normally fall below 5 to 8 l/s per occupant. This is best achieved by creating continuous air changes of 0.5 to 1.0 every hour, throughout the entire dwelling as specified in D.E.T.R. Good Practice Note 268. Although Building Regulations relate to new buildings, the guidance on ventilation is applicable to existing dwellings and, most important of all, the regulations are concerned with minimising the risk to health from the build up of pollutants. KHRV150 helps to satisfy all of these criteria. Downloads Wykamol - KHRV150 - Data Sheet - 2001 10
