International Women in Engineering Day- Samantha Murcutt

To mark International Women in Engineering Day, we are celebrating the valuable contribution women make within our engineering team at IG Lintels. International Women in Engineering Day celebrates the important role women play in this traditionally male dominated industry and encourages young women to consider a rewarding career in an innovative industry. Samantha Murcutt, Technical Detailer at IG Lintels shares the advice she would give to young women considering a career in engineering.

 

What made you want to develop a career in the construction/ engineering sector?

I have always been interested in how things are made. After completing my engineering degree, I worked for a small engineering company that designed parts for the railway industry and tried my hand in Computer Aided Design (CAD).  I really enjoyed working on developing my CAD skills and went on to work for a German firm as a CAD designer, designing coolers on SolidWorks. I started working in IG Lintels in 2015 as a technical detailer and really enjoyed it, and still am enjoying it.

 

Describe your normal working day?

My typical day consists of completing special lintel drawings for approval, this can be anything from two standard lintels welded together to create a corner lintel, to a Venetian arch or bespoke brick feature lintel.

 

What is your favourite thing about your job?

I enjoy trying my best to give a good customer service, sticking to tight deadlines and being as efficient as possible. I also enjoy drawing CAD designs for bespoke lintels for unusual designs.

 

What has been your career highlight to date?

I really enjoyed my visit to The Keystone Group headquarters in Cookstown, Northern Ireland. This is where all the special lintels are manufactured. It was great to see the lintels being manufactured and made from the drawings I had produced.

 

What advice would you give to women considering a career in construction and engineering?

I would say, don’t be afraid to give it a go! Where ever you work, you will have a great support encouraging you to develop and improve. It is a varied, fulfilling career.

 

Hi-therm+ ‘Best Building Fabric Product’ at 2018 Housebuilder Product Awards

House Builder Product Awards Winner

IG Lintels is delighted to have won the ‘Best Building Fabric Product’ award at the 2018 Housebuilder Product Awards for its Hi-therm+ Lintel.

The Hi-therm lintel has been upgraded to offer even greater practicality to builders. IG has invested heavily in R&D to re-engineer the Hi-therm lintel utilising our industry leading ‘top hat’ design. The new Hi-therm+ lintel offers a low cost solution to reduced carbon emissions and is even easier to handle on site.

IG Lintels MD Derrick McFarland commented: “IG recognises the challenges facing house builders in relation to the increasingly demanding regulatory controls on thermal performance and sustainability. We recognise that a fabric first solution is preferable to builders, particularly something that is easily installed, maintenance-free and can allow them to design with 100mm cavities to ensure maximum floor space in developments. We are therefore proud to have been recognised for our commitment to the Fabric First approach. Our original Hi-therm Lintel won this award in 2013 and 2014 so for our innovative new design to be recognised again is fantastic”.

As winners of a Housebuilder Product Award, Hi-therm + Lintels automatically become a finalist in the overall ‘Product of the Year’ category at the Housebuilder Awards 2018 which will be held at a prestigious black tie evening event on Thursday 1 November 2018 at the InterContinental London – The O2.

Hi-therm Advances to Meet Market Demands

Hi-therm_zine_December_IG

The award winning Hi-therm lintel has just been updated in response to requests from house builders to further its application. The Keystone Group’s National Technical & Specification Manager Richard Kinloch explains how this new version secures all the benefits of the original and adds new features, which widen its appeal.

Hi-therm has made a significant impact on the energy efficiency of new homes. It remains the only BBA approved thermally efficient lintel on the market and has won multiple awards for innovation. Now, its design has been upgraded to offer even greater practicality to builders and to make its benefits open to even more projects.

Richard explains:
“Originally our design was based on the most common wall construction types and the typical opening sizes found in most developers’ homes. Now, four years on, we are starting to get more demands and this has required us to re-engineer the design. For a start, Hi-therm+ will now be available to suit both wide outer leaf and cant brick applications rather than just standard leaf. In addition, longer lintel lengths are now available to accommodate larger openings.”

The same but different!

Hi-therm is a patented innovation based around introducing a polymer element into a steel lintel. This creates a powerful thermal break which dramatically reduces thermal bridging through the junction with beneficial cost and performance outcomes. Previously the design utilised a polymer outer leaf as the thermal break. This new Hi-therm+ lintel features a structural polymer thermal break in the cavity linking an outer and inner steel leaf. The resulting improvement in Psi value is considerable with figures of between 0.03 – 0.06 W/m.k to be expected depending on the specific wall make up.

Richard explains the benefits of the new design.

“Buildability lies at the heart of Hi-therm’s success because what the builder wants is a high performance lintel that can be handled and built on site in exactly the same way as standard lintels. Split lintels and other non-structural thermal breaks are not comparable in terms of buildablity and do not offer the simplicity of the Hi-therm lintel.
Hi-therm+ takes practicality to a higher level again, so it will be even easier to handle on site than before. This is an increasingly important benefit and addresses the challenge of maintaining good detailing when skill levels are under pressure and introducing specialist techniques can be problematic.”

Expert support

SAP is a complex subject and even the most experienced technical managers are likely to rely on a trained energy assessor, either from within the team or from an external consultant. It’s therefore reassuring to know that IG & Keystone’s own expert support is available. Online tools such as the Hi-therm Psi value calculator, which issues certified performance for any given wall type, will assist energy assessors.

This, coupled with the fact that Hi-therm+ is a highly tested and certified product, will give reassurance that IG is the ideal partner to provide the optimum lintel solution going forward.

Real cost savings

As more plots fall under Part L 2013, the need to reduce thermal bridging increases. It is here that Hi-therm+ makes a significant impact as its cost benefit relationship is so effective, offering significant cost savings compared to many of the popular alternatives, which builders might be considering as a solution to improved SAP performance.

For example, in a comparative case study for a house type, using Hi-therm+ would incur less than 20% of the cost of increasing the cavity width by 50mm for the same saving in CO2. These CO2 savings are important within SAP because they give flexibility for compliance in situations where other built details are not meeting the standards in Appendix R of Part L 2013.

Fabric First Approach to Sustainable Construction [Whitepaper]

IG Lintels Fabric First WhitepaperIG has published an independent Fabric First Whitepaper exploring the benefits of an improved building fabric as a preference to low carbon or renewable energy technologies.

The research paper, which was conducted by AES Sustainability Consultants, provides a detailed overview of current policy and research on energy conservation and reduction of CO2 emissions. This document demonstrates that a ‘fabric first’ approach can achieve improved CO2 reductions most efficiently.

The introduction of Fabric Energy Efficiency standards into Part L of the building regulations intended to “discourage excessive and inappropriate trade-offs…for example poor insulation standards being offset by renewable energy systems with uncertain service life spans”. NHBC Foundation research also supports this view, with a 2013 report stating “the most robust way to minimise energy use is through the building fabric. Getting the fabric right will save energy for the whole life of the dwelling”. Renewable technologies, on the other hand, have a limited lifespan and risk a significant increase in CO2 emissions from a development once they reach end of life, if not replaced at significant cost to the homeowner.

The findings included in the paper purport that a fabric First approach is found to be technically, environmentally and economically more viable than the installation of low carbon and renewable energy technologies.
Lintels are in most cases the most significant non-repeating thermal bridges. As traditional style lintels interrupt the line of insulation with a continuous piece of highly conductive steel. The Hi-therm lintel utilises a two-piece construction, with a galvanised steel inner leaf supporting the inner blockwork connected to a GRP outer leaf supporting the outer leaf. The GRP component has much lower thermal conductivity than steel – 0.2W/mk as opposed to around 50 W/mK, reducing heat loss substantially.

A review of the Hi-therm lintel, carried out by AES Sustainability consultants found that Hi-therm performs approximately 80% better than standard steel lintels, with calculations demonstrating that overall heal loss through thermal bridging may be reduced by approximately 34% through the specification of Hi-therm Lintel.

Always Insist on BBA Approved Lintels

Third party certification is extremely important for construction products. Certification means that an independent body has reviewed the manufacturing process of a particular product. It has been independently determined that the final product complies with safety, quality and conforms to British and European standards.

This valuable third party endorsement for a product’s performance gives specifiers and contractors extra reassurance that your products have been rigorously tested to industry standards.

The BBA is one of the UK’s leading bodies who offer approval, certification and testing services to manufacturers of products and systems supplying the construction industry.

Products that receive BBA certification are recognised by building control, government departments, architects, specifiers and industry insurers such as the NHBC. It is a mark of quality, safety and reliability that provides reassurance that a product is fit for purpose. It is therefore crucial for construction products or systems to achieve this certification.

BBA Certification and Lintels

Steel lintels are critical elements and should be made in a factory governed by thorough quality control manufacturing procedures. BBA certificated are awarded only to lintel companies who continuously carry out approved load testing and operate under strict quality control procedures. Keystone Lintels is one of the few companies who have BBA approval for their lintels. The Hi-therm lintel, for example, is the only thermally broken lintel on the market that has trusted third party certification from the BBA, who have tested the design, strength, performance, durability and fire resistance to ensure the product is fit-for-purpose and meets British and European standards.

The benefits of specifying Hi-therm

Statistics have shown that up to 35% of heat loss in a dwelling is through thermal bridging [see also: ‘Thermal Bridging and Psi Values: An understanding’]. Selecting the correct Lintel can be one of the single most influential contributing factors that can improve a dwellings Standard Assessment Procedure (SAP) calculation. By improving the lintel Psi value alone, we can significantly improve the SAP calculation, negating the need for more expensive solutions such as wider cavities or costly renewable technologies.

It is essential that specified lintels are backed up by 3rd party certification such as BBA approval to guarantee robust thermal performance, as well as fulfilling their primary function, to provide structural support.  The Keystone Hi-therm sustainability lintel provides designers, architects and developers a simple, certified and cost effective solution.

Here are the top benefits of specifying Hi-therm lintels:

The only one-piece lintel to comply with 2013 Part L building regulations

Standard lintels are made of a highly conductive material: steel. Thus, they contribute significantly to the buildings overall thermal bridges. The GRP component of the Hi-therm Lintel means that it has much lower conductivity than steel therefore forming a thermal break reducing total heat loss substantially through the lintel. In fact changing from a steel cavity wall lintel to a Hi-therm Lintel could improve the lintel thermal bridging by up to 80%. The Hi-therm Lintel can achieve Psi value of between 0.04W/m.k – 0.06W/m.K, meaning it is the only one-piece lintel on the market that complies with the Appendix R values within Part L of the 2013 building regulations.

One-piece lintel, bonding two leafs of a wall together. Negates the need for separate lintels

Hi-therm is a one-piece sustainable lintel solution. The Hi-therm lintel bonds the internal and external leafs of a cavity wall together by spanning the intervening gap, this gives a wall more lateral stability. The patented Hi-therm lintel utilises a hybrid design with a galvanised steel component supporting the inner blockwork connected to a GRP component supporting the outer brickwork.

With separate split lintels, double handling is required as the two lintels are installed separately. This solution also requires temporary propping of the lintels, more wall ties to stabilise the cavity, additional cavity closers, complicated DPC cavity tray details and awkward insulation details to ensure all the voids between the lintels get insulated.
The Hi-therm Lintel, however, is installed exactly as a regular cavity lintel, with no extra components needed and no extra labour.

BBA Certification & Technical Support

Hi-therm is the only thermally broken lintel on the market that has trusted 3rd party certification from the BBA, which tests the design, strength, performance, durability and fire resistance to ensure the product is fit for purpose. A BBA approval also gives NHBC acceptance for full peace of mind.

Moreover, we can offer bespoke PSI value certificates or calculations which can be produced for your specific cavity build up for free via our website here. This is a unique service, and will ensure your energy or SAP assessor can gain the maximum performance benefit within the SAP calculations.

Hi Therm does not require a cavity tray Damp Proof Course (DPC)

DPC cavity trays are a tricky detail to install correctly. Hi-therm Lintel does not require a DPC cavity tray*, saving time on installation and reducing the overall cost of the build. The insulation which is factory fitted within Hi-therm also helps ensure consistent continuity of cavity wall insulation without any thermal breaks.

*Unless in areas classified as severe by NHBC

Outperforms stainless steel on price and corrosion resistance

NHBC recommend that Stainless Steel lintels should be used if building within 500 metres of the coast line. Hi-therm is an excellent alternative to stainless steel lintels and has the seal of approval from NHBC to be used a replacement to Stainless Steel. Not only is it less expensive than its stainless steel counterpart, it is also is more thermally efficient. Moreover, with the Hi-therm GRP outer leaf it is more corrosion resistant than stainless steel, making it ideal for any coastal project.
