Is the doorway to a MMC model 'Open'?

Kirkwood Timber Frame's FastBuild® ClosedPanel system is an innovative product that really enhances the benefits that timber frame and Modern Methods of Construction (MMC) can offer.

However, for those taking the first steps towards a timber frame construction model, OpenPanel is still proving extremely popular. Our head of Sales England and Wales, Andy Lewis, explains:

"In Scotland, where over 90% of new homes are constructed using timber frame, ClosedPanel is widely used. Panels are fully sealed and airtight, complete with insulation and service cavities, and deliver a host of energy efficiency properties which enhance our client's builds. Yet in England, where timber frame adoption has been much slower, OpenPanel - which still boasts excellent cost reduction and sustainability credentials - is as widely used as ever. Could it be offering a gateway to MMC and timber frame utilisation?

"I think there are a number of factors behind what we are seeing south of the border. Firstly, our OpenPanel timber frame system is an excellent product. Panels can be precision engineered to customers’ requirements and offer a high quality, cost-effective and streamlined solution which is perfect for the construction of durable and eco-friendly projects.

“Customers can choose from a menu of options, selecting one that represents the best value to a specific project. This means they can decide how best to integrate the structural kit with their existing operations. For example, insulation can be installed by a preferred sub-contractor on-site - the OpenPanel product allowing flexibility in the programme for this.

"The timber frame system can be erected in as little as one day and watertightness achieved much more quickly. This mitigates delays due to bad weather delivering greater confidence in build programme timescales and making follow-on trades easier to plan for. All of this helps the customer to reduce cost.

"As well as being reliable, sturdy and well tested, OpenPanel has been more widely used historically - which means site teams and contractors are more familiar with it. This can make planning for a first timber frame project much simpler and experienced people easier to source.

"I accept not all, but many people are averse to change. OpenPanel represents a good middle ground - both in cost and adaptation requirements - to test the water. It is a simple and effective solution which delivers successful outcomes for those taking the first steps towards an offsite manufacturing model.

"I genuinely think, as developers become more confident and familiar with using OpenPanel timber frame products, they will transition towards ClosedPanel, to realise the additional benefits it can bring to a project. But for now, and for those looking to start using timber frame, OpenPanel offers an excellent way to begin.”
