DuPont™ Tyvek® Reflex and DuPont™ AirGuard® achieve impressive results for a new timber frame house build in Ireland

Scandia Hus, the largest designer and supplier of Swedish energy saving timber framed homes in the UK, is using ACTIS Hybrid insulation on many of its projects.

This self-build project was looking to improve the quality of the 1st floor construction, eliminate any danger of floor creaking that is common to timber floors and include an efficient underfloor heating solution.Underfloor heating work at its most efficient when it is installed within a screed, this is the way ground floor system are installed and being able to replicate this pipes in screed arrangement upstairs makes sense for the performance of the complete system.Also, by including some stiffened mass to the upper floors, the feel of the floor is replicated from the ground floor and also provides some very useful solar thermal buffering to keep summer temperatures under control in a building technique that otherwise has very little mass to to achieve this, especially on the upper levels.A timber frame structure requires the floor to provide racking to prevent the building from twisting. Meaning the floor needs to be secured to the joists below so the floor can stop twisting. There are 2 ways of installing Lewis Deck in timber frame structures. Firstly is to fix the Lewis Deck down or, alternatively, fix a timber deck on top of the timber joists and the Lewis is then laid loose on top of the timber with the resilient acoustic strips in between , thus, further enhancing the acoustic performance of the floor.

Designing, specifying and installing fire rated timber framed butt-jointed glazing is now easier with the assurance of a fully traceable supply chain with the launch of SYSTEMGLAS® Ligna by Promat, one of the country’s leading manufacturers of fire, thermal and acoustic solutions. Ligna gives designers the ideal balance of assured fire protection and maximum light transmission in all kinds of timber framed glazed partitions and screens. Ideal for offices, healthcare, education, retail and public sector applications, it has been tested to provide integrity and insulation (EI) fire protection from 30 minutes up to 60 minutes (EI30 to EI60).

DG Timber Solutions, specialist designers and manufacturers of timber frame construction were awarded the contract to build the structure’s wall panels in the factory and install on-site, with the objective of achieving an overall wall U-value of 0.20W/m²K.

As part of an exciting regeneration project in Cardiff, Lowfield Timber Frames specified SMARTPLY AIRTIGHT panels alongside a supply of their timber kits for a development of 12 two-bedroom houses in Heath, Cardiff.As part of an exciting regeneration project in Cardiff, Lowfield Timber Frames specified SMARTPLY AIRTIGHT panels alongside a supply of their timber kits for a development of 12 two-bedroom houses in Heath, Cardiff.The homes are built to strict Passivhaus standards, offering improved health and wellbeing conditions for occupants whilst requiring very low levels of energy for space heating or cooling. Additionally, using timber frame for the construction lowers the carbon footprint of the development.The major benefit of a Passivhaus build is the reduced energy consumption during the operating life of the structure. This will ultimately lead to reduced energy costs, heating bills, and even lower carbon emissions for the planet.The average air test result for the 12 homes came in at below 0.5 ACH. A Larsen truss panel (a lightweight wall extension which creates extra wall space to a house insulation) was also used in the project. It was 330mm deep with the finished wall make-up being closer to 500mm.Darren Jarman, Managing Director of Lowfield Timber Frames, commented: “The Highfields scheme in Cardiff was just one of several passivhaus schemes we have completed over the past 2 years. We now have an external wall build-up that not only meets the passivhaus standards, but also has extremely low embodied carbon credentials.“The external wall has been fire tested and achieves the airtightness required, all in all, reducing the heating requirements and the running costs of the property.”SMARTPLY AIRTIGHT is an airtight OSB/3 panel with integrated vapour control and air barrier properties for use as structural sheathing in timber frame structures. The airtightness is engineered into the OSB panel substrate, whilst the factory applied specialist surface finish technology provides increased and constant vapour resistance on the warm side of construction. The panels are suitable for both new build and renovations.The distinctive green layer of SMARTPLY AIRTIGHT is a UV cured coating providing increased and constant vapour diffusion factor. In addition, it provides a smooth and durable surface for taping the connections.The panels made to OSB/3 grade, are moisture resistant and can be used in humid conditions (service class 2). The hygroscopic nature of the OSB panel acts as a humidity buffer to help prevent interstitial condensation within the timber frame structure in limited cases of reverse diffusion.Jarman concluded: “Whilst there are other products available which will achieve the airtightness, we feel SMARTPLY AIRTIGHT is the most robust solution available and eliminates the possibility of accidental damage, resulting in a failed test.”The ambitious project is part of the ‘Cardiff Living’ programme, a 10-year partnership between Cardiff Council and Wates Residential, which will deliver 1,500 new homes at sites across the city.Discover more about SMARTPLY AIRTIGHT and its applications here: https://mdfosb.com/en/products/smartply-airtightFind out more about Lowfield Timber Frames here: https://www.lowfieldtimberframes.co.uk/Twitter: @LTFltd

Aberfoyle Primary School – Stirling, ScotlandProduct: Denver Timber Cycle ShelterSize: 6.2m x 1.6mTimber Frame Stain Colour: Light OakContractor: AKP Scotland Ltd.Architect: Wardell ArmstrongInstallation Date: May 2021The BriefAKP Scotland Ltd. are an award-winning principal contractor based in South Lanarkshire, Scotland. They were working on a project at Aberfoyle Primary School in Stirling which required a complete refurbishment of their stunning gothic style, 151-year-old listed building.Part of the project included the requirement for a cycle shelter within the school’s nursery playground. The Architects, Wardell Armstrong specified our Denver Timber Cycle Shelter in the setting out drawings, which were then sent to us to us an invitation to tender by AKP Scotland Ltd.The Solution Because the product had already been specified, this was a simple case of sending over our costs for the size required which was 6.2m x 1.6m.The Denver is constructed from stunning curved Glulam timber beams which are manufactured by gluing together laminates of timber under pressure and heat that are then perfectly planed. The resulting beams are strong, stable, and corrosion proof with significant advantages over structural steel and concrete.This makes the Denver Timber Cycle Shelter a great choice for this project; because the school building was a very old, listed building, the aesthetics of a curved timber structure would fit in perfectly, keeping a traditional, natural appearance.The Installation An order was placed in December 2020 with the installation planned for May 2021 as set out in the contractors’ building programme. The contractor installed a concrete base and the installation of the shelter went ahead as scheduled on 24-26th May 2021, taking just two days to install.The contractor supplied and installed the cycle hoops themselves once we had left site.The end result is a striking curved timber cycle shelter that fits in flawlessly with the recently refurbished Early Year’s playground area, finishing the project off perfectly.

THE PROJECT: Recticel supplied the low-thermal conductivity insulation boards to ensure new-build homes within a large residential development attained the required levels of thermal performance. The 450-home complex in Salisbury Plain, Wiltshire was fitted with Eurothane® GP boards, which were installed within the properties’ timber-frame cassettes. The insulation was specified for its excellent thermal conductivity of 0.022W/mK. In addition, the boards’ consistent tolerances, straight edges and flatness enhance their usability without compromise to durability. The cassettes containing the insulation were assembled off-site before being installed within the properties’ walls.THE SOLUTION: For this project, the client required a high-performance PIR insulation board that offered walls throughout its collection of houses and bungalows superb thermal performance. This, along with their easy handling ability, made Eurothane® GP boards the ideal solution. It led to the development achieving a U-value of 0.21W/m2K which is above the project’s specific regulatory requirements. It means when the first occupants inhabit this beautifully designed, modern development, they will be inheriting homes that are as comfortable on the inside as they are attractive on the outside.Derek Gough, Senior Estimator at Taylor Lane Timber Frame, which delivered the project’s timber frame properties explained:"Our excellent working relationship with Recticel was key to the success of this project. It’s a collaboration that thrives on their products’ quality, technical expertise and our installation skills and long-held construction experience."About Eurothane® GP:Eurothane® GP is a high performance PIR insulation board that is light weight, easy to cut, handle and install.

Green Square Accord constructed the first virtually plastic free homes in Europe in 2022. 12 Apartments were constructed on the site in Redditch. In-Design & LoCaL Homes worked to find innovative and practical ways to not only reduce plastic use in construction, but to virtually remove the use of plastic in the entire design. The homes feature innovative components including wiring made with mineral insulation and Graphenstone paint which will absorb 10kg of CO2 and does not give off Volatile organic compounds (VOCs) which can be damaging to the environment and may have health implications. The homes are closed panel timber framed with a MVHR system using natural materials in kitchens and bathrooms including sisal flooring. Our closed panel timber frames reduce carbon used in manufacture and the timber comes from sustainable forests to reduce net carbon emissions. Our panels are also quick to install reducing emissions from construction. This, combined with our factory process which ensures that any waste is recycled where it can be, makes our houses as sustainable as possible. Arden Windows Ltd of Coventry were selected for the manufacture, supply and installation of the windows and doors for this project. Arden are fully certified to ISO9001 and ISO14001 and were able to meet the high thermal and security specification requirements of this project with ease incorporating Triple Glazing, and their Secured By Design certified system. Arden were able to demonstrate their sustainability credentials and low embodied carbon throughout the production process. Arden only use sustainable FSC® timber in the manufacture of their windows and doors, meaning the timber used is fully traceable to the source forest and any harvested trees are replenished. Timber window frames are Carbon Neutral over their lifetime and are a great way to reduce carbon footprints in construction. Furthermore Arden offset carbon by burning waste wood and sawdust to create heat for their factory and all products are supplied fully finished using water based coating systems.
