Puts the ‘Break’ in Thermal Break www.insula.ltd.uk

Regardless of who you are, where you live or what you do, theworld is going green like never before and everyone has a partto play.

It is a little known fact that buildings are the main cause ofwasted heat energy within he EU, with cold bridgingaccounting for 40% of total heat loss from the building..

The introduction of new building regulations in 2002 concerningthe presence of thermal or cold bridging within buildings (PartL1a) is still catching many people, from architects to structuralengineers alike, unaware and unprepared.

Stopping thermal bridging is one of the most effective ways todrastically reduce the amount of wasted energy from buildings, therefore, the need for a versatile thermal break connectionable to completely break the conductive path without compromising the load bearing capacity of the connection is greater thanit has ever been.

Archtechnik are proud to announce their innovative range of ThermConX thermal break connections, designed to provide asolution for every instance where thermal bridging needs to be avoided.

What are the benefits of ThermConX?

• ThermConX contains no conductive path for heat energy to escape while still retaining full structural integrity.

• A single ThermConX unit saves the equivalent amount of energy as a continually burning 60w light bulb.

• ThermConX is the only thermal break connections to have been awarded full L.A.B.C. National Type Approval.

• ThermConX is totally inert and requires no running or maintenance costs for the lifetime of the building.

• ThermConX is available in a wide range of styles to suit all applications and methods of construction.

• ThermConX stops interstitial condensation and the formation of mould.

• ThermConX is delivered to site complete with all fixings, ready to be installed immediately.

• ThermConX is fully patented technology.

Introduction

Why don’t they work?

ThermConX are the only thermal break connections able tocompletely break the conductive path while retaining the fullstructural integrity of the connection.

The reason this is possible is because ThermConX are notreliant on metal supports running through the connection inorder provide the necessary structural integrity and loadbearing capacity.

Currently, the most common method of thermal breakconnection design is based on a procedure known asbreaking the beam. This procedure involves breaking themetal beam so that fixing plates can be welded back ontoit. In between these fixing plates layers of neoprene and plastic are placed which are secured within the joint once theconnecting bolts are tightened and the plates drawn back together.

Why doesn’t this method work?

There are two main reasons as to why this method of thermal break connection design is flawed.

1) The procedure of breaking the beam means that the structural integrity of the beam and the connection becomescompromised and therefore considerably weakened. Sections of the metal beam will be located within the insulated cavityof the building.

2) The fixing bolts run right through the connection, maintaining contact with both ends of the beam.

This continuous contact through the connection means that there is still a pathway across which heat energy is able to traveland escape. This means that a very efficient cold bridge is still present.

The diagram above clearly shows the cold bridge created by the metal bolts, and the subsequent loss of heat energy throughthis cold bridge. Heat energy applied to the left hand steel member can be clearly seen conducting through the connectionin to the metal beam on the right..

In line with our Quality management systems we havea program of continuous professional development tocarry out ongoing research and development for ourrange of products. We continually undertake a seriesof in-house testing to gather accurate data about thethermal effectiveness of our products and to enable usto improve and develop further solutions for coldbridging in the build environment.

Independent research from the market place tells usthat in an effort to try and eliminate cold bridgingbetween two metal beams some Architects andBuilding Contractors specify an isolation pad to beused between two backing plates. This is usuallymade out of neoprene, plastic or a similar nonconductive material. A section of the product is placedbetween two metal plates and the joint is drawntogether usually with 4 metal bolts. We havereproduced this type of connection in our test lab totest its effectiveness at stopping or reducing the

passage of heat energy along the metal member thereby eliminating the cold/heat bridge. Further results of our testing canbe found on our website at www.insula.ltd.uk.

How thermally conductive is ThermConX?

After carrying out extensive thermal modeling testing, we have been able to prove conclusively that our range of ThermConXthermal break connections have a thermal conductivity value (U-value) of 0.2w/mk. Each connection’s U-value is calculated inaccordance with both BN443 and BS EN ISO 6946 documents. Every thermal break connection that we supply is testedbefore it is sent to site to ensure that there is no pathway along which heat energy is able to travel and escape.

U-values should be calculated in accordance with the document BR 443; "Conventions for U-value calculations". Thedocument refers to the simplified method for performing U-value calculations as described in BS EN ISO 6946; "Buildingcomponents and building elements Thermal resistance and thermal transmittance – Calculation method". This method issuitable for the majority of common constructions, and is how U-value calculations are traditionally carried out. (Or, at least,that's how most U-values should be calculated.)

But both documents (BR 443 and BS EN ISO 6946) point out that that there are situations where the simplified method givenin BS EN ISO 6946 is not valid. The main situation, which invalidates the simplified method, is where an insulated layer isperforated with metal. Where the simplified method cannot be used, a numerical modelling approach must be adopted, inaccordance with the requirements of BS EN ISO 10211; "Thermal bridges in building construction – Heat flows and surfacetemperatures".

How effective is ThermConX?

ThermConX utilises a combination of the very latest high technology ceramic alloy materials with cutting edge computer aideddesign in order to completely negate the requirement for continuous metal contact through the connection.

ThermConX not only solves the problem of cold bridging at source but also retains the connections ability to withstand loadingsin compression, tension, shear and moment forces.

Correct ThermConX Installation

This diagram shows how ThermConX (Shown here inblue) fits snugly within any standard 100mm cavitywhen attached to two 10mm backing plates.

A snug fit is essential to ensure that no cold or heatenergy is able to enter the insulated cavity.

Incorrect ThermConX Installation

This diagram shows how an incorrect ThermConXinstallation renders the connection ineffective.

In this instance the ThermConX connection isallowing heat or cold energy to enter the buildings’insulated cavity, thus creating a thermal bridge andnegating the effect of the insulation.

What are these new regulations?

Building Regulation Part L1aThe Conservation of Fuel & Power

The guidelines proposed by building regulations stated that:

“The building fabric should be constructed so that there areno reasonably avoidable thermal bridges in the insulationlayer caused by gaps within the various elements.”

Although the 2002 building regulations highlighted, for the firsttime, the need to remove cold bridging from the design of newbuildings, they offered only vague guidelines. Due to the vaguenature of these guidelines, many companies began producing andmarketing products called thermal break connections which didlittle or nothing to even reduce the amount of heat energy beingwasted, let alone stop it completely.

National Building Specification (N.B.S.) introduced new guidelines regarding surface condensation, one of the major concernscaused by the presence of cold bridging. They proposed that: “To maintain an adequate internal surface temperature,and thus minimize the risk of surface condensation, it is recommended that the thermal transmittance (U-value)of any part and at any point of the external fabric does not exceed 1.2 w/m2k.”

Although this proposed a value to which thermal break connections must conform, it was not a mandatory requirement and soineffective thermal break connections continued to pass through unchallenged by building control.

Does ThermConX have any formal accreditation?

Yes it has. ThermConX are the only thermal break connections to have been awarded full Local Area Building Control (L.A.B.C.)National Type Approval. Building control will only award national type approval to a product once stringent evaluation has beencarried out to ensure that the product is fully compliant with building regulations. This certification ensures complete peace of mindthat whatever ThermConX thermal break connections have been specified in order to stop cold bridging there will be no objectionsfrom building control and/or building professionals. In conjuction with BRE at Watford we have carried out a very detailed programof continual development and testing of our product range enabling us to bring to market a leading edge innovative range ofsustainable products for the building enviroment. The development of this close working relationship has acumalated in our productrange being put on permanent exhibition (September 2011) in the BRE Innovation Park at Watford a world leading and groundbreaking demonstration development designed to give a glimpse of how the future delivery of sustainable buildings andcommunities can be achieved not only in the UK but around the world. Included below are some companies we have worked withto gain accreditation throughout the UK and Europe.

What are the health effects?

The main health concern caused by the presence of cold bridging isthe formation and growth of mould and mildew.

If mould is absorbed into the body, either through inhalation orvia moldy food, it can cause extreme sickness and lead to theformation of poisonous and even carcinogenic substances.

Mould can also cause serious allergic reactions in the bronchiaand lungs. Mould can also grow in the lungs and sinuses andbecome invasive in immune-suppressed people.

What is mould?

Mould is a type of multi celled fungi which forms in areas where a condensational build up occurs due to the meeting ofwarm and cold air.

This build up of condensation leads to the formation of cold spots which in turn leads to the formation and growth of mouldand mildew.

The following quote is taken from a report published in the Independent newspaper.

“An investigation for the Royal Institute of Chartered Surveyors (RICS) by the specialist Fugenex found harmfulmould in around 25 per cent of homes.Fugenex performed DNA analysis on themould present in the homes it studied,discovering the toxic variety, known asStachbotyrs Chartarum, was remarkablycommon. It has been linked with cancer,asthma, bronchitis and causing allergies.”

This picture shows the early effects of mouldgrowth created by the balcony connection onthe floor above.

32Timber TeeConnectionsThe most cost effective method ofattaching a Structural thermally brokebalcony connection to a timberconstruction is by double joisting, thisinvolves inserting within the floor voidtwo solid timber joists side by sidewhereby an Insulà Timber Teeconnection can be fitted as shown inthe diagram.

This is a very efficient load bearingconnection due to the Tee element ofthe connection having protruding teethwhich bite into the surface of thetimber joists when compressed,allowing the cantilever forces within theconnection to be transferred to shearacting on both surfaces of the joists.

This makes for a very efficientconnection as it does not rely on theclamping force generated by thecompression plates and bolts whichhave a danger, under load, of splittingthe grain of the timber, causing failureof the connection.

With insulation values only achievablewith the “no metal, through fixings”technology developed by Archtechnikthe passive house connection has Uvalues of ? ,but with no reduction in itsability to transmit load.

These new generation connections allow the Architect and designercomplete freedom in building design while respecting societies longer termneeds. The image below shows a typical passive house type cavity; in thiscase 350mm.

Retro Fit RangeThe following diagram depicts a house with 200mm external insulation; the numbers represent where each of the retro fitproducts would be used on such a project.

Archtechnik has applied its thermal break technology to the emerging retro fit market, whereby in order to meet the ever increasingrequirements placed on our existing Housing stock to meet the new energy reduction targets the insulation values of the propertieswill need to be increased significantly. In most cases this can only be achieved by retro fitting approx 200mm of insulation on theoutside of the building's existing envelope. This is creating a requirement for a range of low loader thermal break connections toattach many building products to the outer envelope of the building.

It will not be possible to attach to the 200mm of insulation or the thin protective coat of render to any item which is requiredto exert any load on to the substrate. There will be a requirement for a range of low loader thermal break connections whichwill require a first fix element to be fitted to the existing brick work before the insulated jacket is applied and thereforeArchtechnik has started to developed a range of connections to fulfill those demands.

The diagram above depicts a typical rendered house with 200mm external insulation. There are many features attached tothe outside of this structure and different types of Insulà retro fit connections designed in order to fasten them back to thebuilding whilst avoiding a cold bridge. The house is labeled with numbers on or next to a certain external attachment; thesenumbers correlate to the numbers of the connections listed in the next few pages.

Retro Fit Range


361. Block Connection

DescriptionThe Block Connection holds the most loads out of all the retro fitrange, designed to support items requiring heavier capacity needs.

Applications• Security Cameras• External Lights• Alarm Systems

2. Plug Connection - DeepDescriptionThe Plug connection is ideal for products of medium weight;however they do not require connecting back to the brickwork ofthe building. These connections sit inside the insulation on theoutside of the house.

Applications• Trellis's• Letterboxes• Large External Lights

3. Corner ConnectionDescriptionCorner connection is named due to its applications often on thehouse corners, where brackets and hinges are required for gates andproducts with a swing factor. They fasten to the brickwork and only asmall area of the connection is exposed outside the render of thehouse.

Applications• Window Shutters• Gates• Any corner fix application


374. Counter Bore Connection

DescriptionThe Counter bore is used only for the lightest of external products.This connection is wider yet shallower and perfect for productssuch as those listed below.

Applications• All rainwater downright pipes• Signage• House Numbers

5. Dish ConnectionDescriptionThis was developed due to a rise in demand for options to attach aSatellite Dish and bracket back to a retro fit house whilst remainingthermally efficient. One of the more heavy duty connections in therange uses the Insulà system to thermally break the Dish whilstmaintain the load capacity required when attached back to thehouse itself.

Applications• Satellite Dishes

6. Blade ConnectionDescriptionThe blade Connection has been designed for use on a externallyinsulated building, however has a much higher load capacity thanthe other connections within this range. The blue, middle part of theproduct has been extended to travel through the external insulationand the case in attached back to the building framework. The bladeconnection is very similar to the Tang thermal break connection;however it has been adapted for use within this range.

Applications• Lightweight canopy


38Archtechnik have been nominated for anumber of awards, however most recentlywas the Rushlight Energy Reduction Award2009.

Awarded to the technology or innovation thatreduces the use of energy in a commercial or consumer setting. This award is open to any kind ofinnovation, technology, product, system or process that has or can significantly reduce the amount ofenergy that is consumed. The winning entrant may have a product or system that avoids energy wastagethat enables less energy to be used for a given purpose or that enhances overall energy efficiency. Theaward is designed to identify, celebrate and publicise a technology, product, system or process that can beadopted or used to reduce the use of energy overall, whether it be for light, heat or fuel.

The ThermConX structural thermal break won the award which took place at a Gala in Westminster, London.The Rushlight Awards are judged by leading experts in their chosen fields who are entirely independent ofsponsors, headline partners and Eventure Media. They have been invited to join the panels due to theirimpartiality, vast experience and knowledge. This is the reason Archtechnik are so proud of this achievement.

The demand for greener and more innovativeproducts in the construction industry isgreater than it has ever been. Such productshowever, are only made possible by marryingthe very latest and most effective tools andsoftware available with lateral and forward thinking concepts. Thermal break connections must be used inevery instance where a cold bridge would otherwise have been created by fixing an item back to thebuilding structure through the insulated cavity. Our extensive range of LABC approved thermal breakconnections offer a complete solution for any and every instance where cold bridging must be avoided.

Whatever the applicationWhatever the designWhatever the value

ThermConX is the only 100% solution.“Within the European Unionsuch vast quantities of energyare being lost through roofs andwalls alone that Europe's entireKyoto commitment could beachieved through improvinginsulation standards.”Andris Piebalgs,EU Energy Commissioner
