For their new home, the Hemsworths chose to use timber frame over other methods of construction because of the speed of build. They wanted to use a local supplier and found Kingspan Timber Solutions while searching the internet. After initial discussions, they decided to use the Kingspan ULTIMA 15 system because of the thermal performance and slimness of the system. They also found that Kingspan ULTIMA 15 was, for them, the perfect balance between thermal performance and cost. They were also swayed by the footprint savings that the ULTIMA system provides.
