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.

A Unique Offsite Solution Delivering Intricate Brick Detailing

IG’s Brick Feature Lintels are one piece prefabricated units, manufactured bespoke to order, achieving even the most challenging architectural designs.

IG Brick Feature Lintels

IG Lintels offers specifiers a technically advanced, offsite solution for an extensive range of brick details including arches, panels, soffits and other architectural features. This unique Brick Feature Lintel system enables complex brickwork details to be carried out in a factory environment providing high standards of quality controls.

IG collects a consignment of bricks from site, cuts these into slips and bonds to IG’s patented Brick Feature lintel product, to suit the client’s design. This eliminates the need for a specialist brickwork contractor spending hours onsite, cutting bricks to suit complicated structural openings. The finished Brick Feature Lintel joins seamlessly with the already constructed brickwork.

Offering a bespoke design service, IG’s team of engineers can use their technical expertise to develop unique solutions to complicated brickwork over openings. By contacting them at an early stage of the design process, architects can potentially gain significantly more design flexibility for their projects. Every Brick Feature Lintel is manufactured bespoke to order, ensuring that each individual unit is customised according to the unique size, shape and aesthetic requirements of the project.

The production of Brick Feature Lintels offsite in a factory environment, ensures that the bonding process occurs in optimum controlled conditions free from wet weather, extreme temperature and excessive dust. The patented design of the perforated steelwork interfaces with the BBA approved adhesive to pass through and form a mushroom on the inside of the steel, forming a mechanical lock between the lintel and the bricks.

IG’s Brick Feature Lintels can accommodate a large range of bond patterns and with segmental arches, flat arches, Gothic and parabolic arches as well as apex arches and bullseyes, the possibilities are endless. These products offer builders and contractors a unique way to enhance the quality of their brickwork detailing in a highly labour efficient way at a time when the skills are acknowledged to be in short display onsite.

IG Lintels Launch Online Psi Value Calculator

IG Lintels Psi Value CalculatorIt is our aim to provide customers with the most advanced technical information in the industry. IG Lintels is the first lintel manufacturer to offer a Psi value calculator designed for energy assessors and architects who specify products and value engineer specifications to meet building regulations.

The key benefit of the Psi value calculator is that you can obtain a Psi value with a few clicks of a button – Free of charge. Generally this information takes a specialist company a few days to turn around with typical costs between £200 and £400 per detail. Energy assessors can now directly input the lintel Psi value into their SAP calculations and view the performance benefit. Specifically calculated Psi values will help lower the Y value within the SAP calculation, in turn assisting Part L compliance.

To ensure accuracy, all Psi-value calculations have been generated by trained thermal modellers using physical Trisco BRE software.

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.

Do you know your windposts?

Alongside our detailed range of lintels and masonry support, IG Lintels also manufactures three types of windposts.

All IG Lintels windposts are laser cut, meaning that when all factors are controlled, laser cutting is more stable, reliable and extremely accurate compared to other cutting processes. Where the tolerance on the plasma cutter is around 2mm – the laser cuts much more accurately and can be as little as 0.1mm.

IG Lintels Windposts

Laser cutting uses a high-powered beam to cut material based on computer-controlled parameter. As the laser guides its beam along the material, everything in its direct path is vaporised, burned or melted. One of the benefits of laser cutting technology is the cut product rarely needs any finishing work as this process ensures a high-quality surface finish.

IG Lintels windposts span vertically between floors to provide additional lateral support for large panels of brickwork or large panels with openings.

U Windposts

The U windpost is the channel section designed for standard loading conditions and is installed within the cavity, and normally spans between floor structures. The inner leaf of the cavity wall is totally undisturbed. The U windpost is also available in shorter lengths for parapets or below windows.

DU Windposts

The DU windpost is a “back to back” channel section designed for heavier loading conditions and is installed within the cavity. As with the U Windpost, the inner leaf of the cavity wall is undisturbed, but the DU is a heavier duty variant of the U windpost.

LP Windposts

The LP windpost is an “L” shaped section designed to suit a range of loading conditions and is built into the inner skin of the cavity wall. The LP normally spans between floor structures.

Parapet And Spandrel Windposts

All three windposts designs are available in shorter length to provide the same level of stability to parapets or below windows, commonly termed parapets or spandrel window posts respectively. These posts are designed as cantilivers and are rarely more than 1.6metres in height. The base connection is engineered to resist bending moment.

Windpost Connections

All of our Windposts are supplied with plates or angles for fixing to the structure at top and base. It is important that windposts are fully fixed before commencement of the brickwork. Although the type of connection will change on a project-by-project basis.

IG Lintels Launches BIM Object Library

In response to the transition of the industry to 3D digital modelling, IG Lintels has launched a comprehensive BIM object library.

With the Government now firmly behind BIM and a commitment for all government bodies to be using BIM by 2016, the demand for BIM or 3D and 5D components will dramatically increase. The initial estimated savings to UK construction and relating clients is £2bn PA through the widespread adoption of BIM and is a significant tool for the Government to reach its target of 15-20% savings on the costs of capital projects by 2015 (HM Government, Building Information Modelling).

Adopting BIM involves much more than simply changing the software used. To fully benefit from BIM, the architecture, engineering and construction industries must learn to work collaboratively in fundamentally new ways. It is a whole new paradigm.

What does IG offer?

IG Lintels now offers all standard lintel profiles in Revit format. We are aware that BIM offers enormous gain and time saving as changes and amendments to the design are automatically altered and accounted for in quantities without lengthy calculations. Our BIM objects also embed key product and asset data and a 3D model that can be used for management of information throughout the entire project life cycle – from first concept through to operation.

2D AutoCAD drawings will continue to be available for the foreseeable future and, in the case of bespoke steel lintels, BIM models are available on request to ensure that we can fully assist design teams, engineers and architects with their requirements. Derrick McFarland, IG Lintels Managing Director, says:
