Diathonite Evolution Lime Cork Thermal Plaster Systems wins at RIAI Archi Expo 2015

Ecological Building Systems Diathonite Evolution Lime Cork Thermal Plaster Systems wins award at this years RIAI Architecture Expo

 

   

Ecological are pleased to announce that their DIASEN Diathonite Evolution Lime Cork Thermal insulating render system won the category "Best Interior Design" award at this years RIAI Architecture Expo hosted at the RDS, Dublin.

 

Diasen, based in Italy, have been manufacturing cork based diffusion open render systems since 1985.

When thermally upgrading single leaf masonry walls, it is critical not only to install thermally efficient materials, but also to ensure that the thermal solution does not impede the ability of the wall to continue to breathe. This is particularly important when dealing with solid brick or stone walls, which utilise a lime mortar and lime plaster systems. Unlike many modern impervious thermal insulation systems, Diathonite Cork thermal insulating plaster, is a breathable insulating plaster which provides the optimum combination of thermal performance and moisture management.

Many internal thermal insulating systems require that the existing wall be levelled with a suitable plaster prior to their application. Otherwise uninsulated cold air pockets between the internal insulation and an existing wall can lead to significant condensation risk. Unfortunately, single leaf masonry walls are often very uneven and may be difficult, costly and time consuming to level out.

On such walls a diffusion open insulating plaster system such as Diathonite Evolution presents the perfect solution to provide both a levelling plaster and thermal insulation in one while at the same time maintaining optimum levels of breathability and moisture management.

Diathonite Evolution is a thermal plaster based on NHL 3.5 lime & pure cork granules. Diathonite Evolution is a natural ecological render system suitable for internal and external use. The plaster system combines outstanding thermal performance with optimum vapour control and high mechanical strength. Diathonite is primarily manufactured from a combination of, cork, clay, lime and diatomaceous earth.

 

The combination of its range of diffusion open natural raw materials ensures Diathonite Evolution insulating plaster systems have an array of unique properties including:

  • Thermal Insulation: With a thermal conductivity of only 0.045W/mK, the plaster system attains excellent thermal resistance, which significantly increases the thermal resistance of solid walls.

  • High Thermal Mass: The insulating plaster system also features a high thermal mass, providing effective thermal insulation all year round.

  • The insulating plaster system features extremely high compression resistance (2.7 N/mm2), for increased robustness making it ideal for either internal or external use.

  • It is extremely diffusion open (breathable) with a µ value of only 4.

  • High Fire Resistance: The insulating plaster system has an extremely high fire resistance, is non-combustible and does not emit smoke (Euro class A1).

  • The plaster features extremely high elasticity, ten times more than that of traditional plaster systems, ensuring the risks of cracks are minimised.

  • Thanks to cork and its porous structure, Diathonite contributes to sound absorption and acoustic insulation.

  • The diatomaceous earth helps to reduce fluxes in humidity within the living space, providing optimum comfort and health levels.

  • The raw materials used in Diathonite Evolution are natural and nontoxic.

Once the plaster is applied, it may be finished with Diasen Argacem MP highly breathable finishing smoothening plaster. Alternatively, a lime based plaster may be applied internally.

 

Diasen’s range of products have attained the quality control certification ISO 9001, the environmental certification ISO 14001, and all their products comply with CE requirements.

Ecological can provide details in relation to trained installers of the system on request.

Roof Refurbishment Renovation WUFI study

Roof Refurbishment Renovation pro clima WUFI study

 

Whether one wishes to retrofit existing buildings or optimise the thermal performance of new buildings, it is essential not only to consider improvements in thermal performance, but also, how modern building materials interact with existing structural elements.

Ecological have pioneered advanced support and guidance for specifiers for over 12 years now using the advanced dynamic hygrothermal modelling programmehe WUFI. WUFI is a useful decision support tool which allows users to interpret the hygrothermal impacts of a range of thermal solutions on the building fabric. pro clima have pioneered Inteliigent Airtightness and Vapour control solutions in both new constructions and retrofits for decades.

 In 2011 pro clima published an in-depth analysis of the impact of retrofitting existing roofs externally with a range of natural (such as GUTEX woodfibre and THERMO HEMP) and synthetic insulation materials and membranes. With the array of complexities which can often arise in roof retrofits, this study is more relevant today than ever before. Their study provides detailed guidance with regard to the thermal refurbishment of roofs with pro clima SOLITEX PLUS, DASAPLANO and INTESANA membranes.

     

This technical paper employs WUFI 1 dimensional and the more advanced WUFI 2 dimensional hygrothermal modelling program to analyse the impact of refurbishing existing roofs with a range materials.

Passivhaus Trust Awards

2015 UK Passivhaus Awards logo

Ecological Building systems were delighted to attend this year UK Passivhaus awards ceremony. The prestigious event hosted by the Passivhaus trust now in its 5th year, was held in the Austrian embassy in London and celebrated some of the very best completed Pasivhaus buildings across the UK.

This year saw a diverse shortlist of certified Passivhaus projects across all three categories. From small-scale dwellings to large-scale social housing as well as the deep retrofit of 19th century terraced houses, this was a further indication of just how far the UK has come in recent years in the development of high performance low energy buildings.

pro clima INTELLO PLUS now BBA & NHBC approved!

 

We are pleased to officially confirm that the pro clima Intelligent Airtightness system, including the pro clima INTELLO PLUS intelligent airtightness and vapour control membrane, has met all the requirements set out by both the BBA (British Board of Agrément) and the NHBC. This compliments the existing Irish Agrément Certificate providing specifiers, installers and homeowners with unsurpassed reassurance.

BBA is the UK’s major authority, offering approval and inspection services to manufacturers, installers, construction products and systems. BBA certification is only awarded after systems or products have successfully passed a broad assessment involving laboratory testing, on-site evaluations and production inspections.

Niall Crosson, Senior Engineer with Ecological Building Systems comments:  “Receiving BBA certification for the pro clima Intelligent Airtightness system reinforces the unsurpassed standards set by pro clima in the manufacture and delivery of durable airtightness solutions which are fit for purpose and last the lifetime of the building. pro clima have already received independent tests to confirm an expected lifespan for their tapes of at least 100 years.  pro clima are pioneers not only in delivering Intelligent airtight solutions, but combining this with optimum protection against condensation and mould growth by utilising Intelligent membrane technology. Receiving BBA certification provides specifiers, engineers and homeowners with even more reassurance that the pro clima Intelligent Airtightness system will assist in delivering a robust airtight result.”

Attaining NHBC acceptance for the use of INTELLO PLUS will also prove most beneficial to homeowners, designers, timer frame manufacturers and installers.

During the assessment process pro clima INTELLO PLUS was evaluated in a range of constructions where INTELLO’s unique INTELLIGENT vapour control properties provide unsurpassed safety against condensation. This  included unventilated flat roofs. The advanced hygrothermal simulation programme, WUFI, was used to carry out assessments in accordance with BS 15026, based on British climate data. BS EN 15026 defines the practical application of hygrothermal simulation software used to predict one- dimensional transient heat and moisture transfer in multi-layer building envelope components subjected to non steady climate conditions on either side. In contrast to the steady-state assessment of interstitial condensation by the Glaser method (as described in EN ISO 13788), transient hygrothermal simulation provides more detailed and accurate information on the risk of moisture problems within building components and on the design of remedial treatment. While the Glaser method considers only steady-state conduction of heat and vapour diffusion, the transient models covered in this standard take account of heat and moisture storage, latent heat effects, and liquid and convective transport under realistic boundary and initial conditions. The application of such models has become widely used in building practice in recent years, resulting in a significant improvement in the accuracy and reproducibility of hygrothermal simulation (BSI 2007). 

 

In the development of the BBA certificate it became clear that there is still some confusion on the market in relation to airtightness and its relationship with vapour control. To assist in addressing this, Ecological Building Systems in conjunction with the BBA will be hosting a series of information briefings throughout the UK early next year. More details will be available on our website later this year.

We have amended our pro clima product portfolio to incorporate the BBA logo for INTELLO PLUS, please follow this link to access the new product portfolio.

Why Airtightness & Intelligent Vapour Control: Lothar Moll of pro clima explains

In March 2007, Lothar Moll, director of pro clima and renowned international expert in the field of building physics, airtightness and intelligent vapour control, published a seminal 2 part technical article regarding airtightness in buildings in the Journal of the Royal Institute of Architects of Ireland.

As airtightness is now a central part of our building regulations in both Ireland and the UK, we thought it timely to upload this 2 part feature.

For anyone interested in Airtightness and vapour control we highly recommend this 2 part feature. The articles may be downloaded from these links:
