The Important Bits

  • The first ever Passivhaus Museum in Wales to house the land speed record car – Babs.
  • Twin Frame / ‘Larsen’ panel construction to significantly reduce cold bridging.
  • Panel are large format – upto 10m span – fewer junctions and seals required.
  • All Passivhaus boards and tapes are factory applied to the panels.
  • Built in lifting loops for crane installation – safe operations designed-in.
  • Psi Values – Engineered and calculated to avoid thermal bridging and air-leakage paths.
  • Blown Cellulose fibre insulation – natural and breathable.
  • Fully designed, engineered and manufactured in-house.

Our national group facilities mean that we are always “local” to each project – and therefore we can ensure the best possible carbon-footprint, for this project our Bridgend factory manufactured the floor and roof cassettes.

On the south Wales coast – Pendine Sands – is best known for its links to the original World Land-Speed record attempts undertaken along its beach. Indeed, to this day the beach is still used by racing enthusiasts and tourists alike to remember these historical events.

The most famous being when the BABS car was driven to a record speed of over 171mph in 1926. Babs was completely restored after a fatal accident at that attempt and has been housed in a museum at the site ever since.

The Welsh government keen to attract more tourism to the Pendine area commissioned WRW Construction to build the first ever Passivhaus museum to replace the existing alongside a new low energy hostel. The ‘attractor’ project part funded by the European Union is designed to enhance the areas tourism appeal and create many jobs for the local area.

Timber Innovations was chosen because of its experience with low-energy buildings to completely design, engineer and install the breathable walls and roof envelope to both the museum and hostel buildings. The Passivhaus specification meant that extremely low U Values and airtightness were required to achieve a ‘near zero’ in-service carbon footprint.

The insulation specification had to be breathable, so we have worked with Warmcell (a pumped cellulose-fibre insulation material made from recycled newspaper) that is injected into our Larsen-stud panels together with breathable facing-boards, Smart-Ply Pro-Passiv and Medite Vent.

We have developed our system ‘Passiv Innovations’ to allow developers to be able to specify and ensure they will achieve 0.11 W/m2K or better in line with Passivhaus requirements whilst achieving airtightness results below 1m3/m2/h @50 Pa.

Large format panels significantly improved the build programme, some walls in the museum are over 8m tall, delivered and installed in one piece. Timber Innovations project manage the complete install from scaffold design plans, full RAMS and trained install team utilising tower cranes or mobile where applicable.

These two buildings (1700m2 development area in total) were completely offsite fabricated – wall, floor and roof panels and erected in just 10 weeks on site ready for follow-on trades to complete.

The ‘Passiv Innovations’ build system, mantra is ‘offsite not onsite’ to ensure that as much as possible is done in the factory to improve quality and reduce build time on site.
