Reasons for Building Airtight

Air leakage accounts for 15-25% of winter heat loss in buildings

Pro Clima’s patented airtightness and weathertightness building systems, in combination with effective insulation and appropriate ventilation, create comfortable, energy-efficient, low allergen-emitting,  healthy homes and places of business.

The system ensures the long term effectiveness of insulation and the structural durability of buildings; enabling them to last for many years into the future.

• Saving energy

Air­tight struc­tures are en­ergy ef­fi­cient. They en­sure that heat in­su­la­tion func­tions op­tim­ally. This re­duces heat­ing costs and CO₂ emis­sions; pro­tect­ing the cli­mate and your wal­let alike.

• Preventing structural damage

Air-sealing helps to protect against mould, rot and other struc­tur­al damage. These types of problems are often the result of indoor air penetrating the thermal insulation during winter, which causes large amounts of condensation.

• Maintaining healthy living spaces

Air-seal­ing prevents mould; reduces air dryness during winter; and keeps liv­ing spaces cooler for longer during sum­mer.

You can read more about the benefits of building airtightness on Pro Clima’s website. The study entitled Pro Clima New Zealand: Airtightness & Moisture Management is also very informative in dealing with various building physics. It contains practical examples and case studies.

INTELLO PLUS

INTELLO PLUS is a high performance airtight and moisture controlling building membrane. It creates the inner boundary for thermal insulation in walls, roofs, ceilings and floors. It is generally applied on the inside of the building between the stud work and the internal cladding.

INTELLO PLUS enables buildings to achieve exceptional levels of airtightness, up to and surpassing the Passive House requirement of 0.6 ACH.

INTELLO PLUS is an intelligent membrane. By sensing humidity variations, it is capable of adapting its molecular structure, in order to allow or deny the passage of moisture as required. This modern building technology provides maximum protection from structural damage and mould; even in the most complex of building structures, and extreme environments.

SOLITEX EXTASANA

SOLITEX EXTASANA creates the outer boundary for thermal insulation in walls, roofs, ceilings and floors. It is generally applied on the outside of the building, between the studwork and external cladding.

SOLITEX EXTASANA is highly moisture permeable, and does not vary its permeability like INTELLO PLUS does. It readily allows moisture to escape the building’s wall cavity, but does not allow external water or rain drops to get in (similar to say, a Gore-tex rain jacket).

SOLITEX EXTASANA is also thicker than INTELLO PLUS, and has a high resistance to UV exposure; making it more durable, and ideal for external applications.

The membrane can be exposed to the Australian elements for up to 90 days when applied to building walls.

SOLITEX MENTO

SOLITEX MENTO membranes are designed to be used with most wall and roof cladding systems. They are generally applied to the roof of the building, between the trusses and the roof cladding.

SOLITEX MENTO has a higher resistance to UV exposure than SOLITEX EXTASANA, making it ideal for rooftop applications.

SOLITEX MENTO can be exposed to the Australian elements for up to 90 days when applied to rooftops.

1. Without Vapour Barriers

When there are no vapour barriers in place; in summer, this risks the formation of condensation on the inside of the internal wall; and in winter, this risks the formation of condensation on the inside of the external wall. Both of these situations can lead to mould, rot and further damage to the building structure.

3. Blocking Vapour at the External Wall

Similarly, blocking the passage of air and vapour at the external wall works well in summer, but traps moisture content inside the wall during winter.

INTELLO’s Diffusion Variability

INTELLO PLUS varies its permeability levels depending on the humidity of its environment. Allowing diffusion of moisture from outside through to inside in summer, and preventing excessive moisture from entering your walls during winter.
