LEADERS IN QUALITY AIRTIGHTNESS & SUSPENDED FLOOR INSULATION.
THINGS TO KNOW
Pre-installation Planning
Whether you are a builder, architect or home owner, it is important to plan the installation of your airtightness, ventilation & Insulation. This will require meeting with the major participants in order to coordinate the work. For example, the foundations on the external wall will need to be made airtight before the insulation layer and screed are put in place. The ceiling under the attic will need to be sealed with INTELLO before the internal walls are put in place or the walls will have to be looped using Solitex to bridge the INTELLO membrane. Proper planning will save save time and expense. It will also provide a better finished result. All the other trades involved will need to be informed about Airtightness. This will reduce the amount of accidental damage done to the membrane etc. Ideally, the ventilation will need to be installed at various stages of the Airtightness installation. Depending on the type of insulation required, the timing of this will also need to be planned in advance. For further information on the Airtightness and insulation materials used, please go to www.ecologicalbuildingsystems.com
Environmental Considerations
At we only use ecologically safe products. The type of insulation we recommend is Cellulose. This is made from recycled paper and is the most environmentally safe product on the market. Our partners 'clioma house Ltd.' would be happy to provide you with a quote. We also install Thermo-Hemp, Thermafleece, Gutex Wood Fibre and Stone Wool Thermal insulation.
Retrofitting Airtightness
There are many elements to consider when installing Airtightness to an older building. This is usually carried out as part of a comprehensive refit of the entire building. However, this is not always the case. Airtightness can be done in stages. For example, if you are installing new windows and doors. Making them airtight will improve your general comfort and save energy. If you are building an extension, this part of the house can be well insulated and made Airtight. Other work can be carried out at a later stage and connected to existing work. You will need to inform your architect, builder or Window installer, that you require Airtightness or Insulation or Ventilation and we can discuss the possible results that can be achieved. Please contact us for further information.
WHAT IS AIRTIGHTNESS?
The amount of air leakage or infiltration a building has. Making a building airtight essentially means eliminating draughts. Airtightness provides almost total control over how much air we're letting in to the building through designed ventilation systems, rather than cold air entering and warm air escaping through unwanted or unseen gaps.
Airtightness is typically measured in two units:
Air changes per hour (ACH) and air permeability (m3/hr/m2). For a typical building, there is usually little difference in the two figures. The smaller the airtightness figure the better. Under Irish building regulations new homes must have an air-tightness of 5m3/hr/m2 or less. The rigorous Passivhaus standard demands an airtightness of 0.6ACH or less.
Whether you are installing Airtightness in your Home, School or Workplace, you are contributing to three very important elements:
Your Health
By making a building Airtight, you are improving the health of all the occupants. The air within the building will be cleaner and less polluted. Air sealing protects against mould, helps prevent dry air in the winter and keeps living spaces cool longer in the summer. Many mould fungi release poisons - such as MVOCs (microbial volatile organic compounds) - and spores as secondary metabolic products that are harmful to human health. The Airtightness, in conjunction with a control demand ventilation system, is particularly advantageous to people suffering with asthma, COPD, Cystic Fibrosis or other breathing difficulties.
​
The Building
The Airtight membrane provides Low Moisture transport in Winter and a High Degree of drying in Summer. The Variability of the diffusion resistance of the High Performance INTELLO systems guarantees impressive protection against structural damage. Structural damage due to mould formation may occur when humid, warm indoor air enters into the thermal insulation structure in winter - e.g. through gaps in the vapour retarder and airtightness layers - and large amounts of condensation are formed.
​
The Environment
INTELLO & INTELLO PLUS consist of a special membrane made from Polyethylene Copolymer. The Fleece and Reinforcements are made of Polypropylene. This facilitates easy recycling. The higher heating costs caused by faulty seals lead to reduced cost-effectiveness of the thermal insulation for the building owner. In addition, there are also higher emissions of CO2 than would be necessary when heating an airtight building. Uncontrolled CO2 emissions contribute to the greenhouse effect, and humankind is feeling the effects of this in the increasing number of environmental catastrophes. For this reason, a reduction in CO2 emissions is desirable. We can help the environment not only by reducing use, but also more importantly by implementing intelligent solutions.
Mechanical Heat Recovery Ventilation Systems.
When you make your building Airtight, you need a mechanical heat recovery ventilation system to ensure clean, fresh, warm air circulation. Building regulations make it clear that some form of ventilation is required in modern more airtight homes. There are several options available.
Mechanical Ventilation with Heat Recovery is one of the most energy efficient methods of ventilating a building. It removes stale, moist, bad air from the building and providing fresh air for your home while at the same time recovering heat that would have been lost in the process.
WHAT IS HEAT RECOVERY VENTILATION?
Since airtight buildings do not allow for the transfer of indoor and outdoor air, they need one or more mechanical ventilation systems to help ensure that the building receives enough fresh air and that indoor air, along with excessive moisture and particulate matter, is properly vented to the outside.
This can be accomplished with fans, air ducts and ventilation control systems with sensors that monitor the indoor CO2 levels. The ventilation system filters the air and provides a much healthier environment for the occupants. As stated previously, particularly those that suffer from breathing related illness such as Asthma. COPD, Hay fever etc.

WHAT IS NZEB
​
Nearly Zero Energy Building (NZEB)
The NZEB standard will apply to all new buildings occupied after the 31st December 2020. For Public Sector bodies, the standard will apply to all new buildings owned and occupied by the 31st December 2018.
As with previous Building Regulations there are transitional arrangements in place where buildings are occupied after these dates but work commenced prior to 31st December 2018.
What are Nearly Zero Energy Buildings
The definition for Nearly Zero Energy Buildings in the Energy performance in Buildings Directive (EPBD) is "a very high energy performance, as determined in accordance with Annex 1, The nearly zero or very low amount of energy required should be covered to a very significant extent by energy from renewable sources, including energy from renewable sources produced on-site or nearby”.

We can provide you with further information on request. Site visits can be arranged. A charge will be made for a site visit, however, this charge will be refunded after the Airtightness installation is completed. The amount will depend on the location of the site. aerZeal Ltd is based in Sandyford, Dublin D18 CV48
