Open Panel

The Open panel system is an industry standard frame. Open-panel framing is quick and flexible compared with on-site construction. Using this system for your project will ensure the main structure is constructed efficiently, leaving you able to complete both internally and externally simultaneously. External finishes can be applied instantly once the frame and roof are erected. Internal finishes including plumbing, electrical and dry lining can also commence once your frame is water tight.


  • Open panel timber frame external walls consist of 140 mm timber studwork fixed in place with sheets of 9mm orientated strand board (OSB) with a foil breathable membrane.  (Insulation between studs is an optional extra) 
  • Timber Studwork frame is manufactured using 140x38mm CLS (Canadian Lumber Standard) C16 treated timber.
  • Internal walls consist of an 89mm x38mm C16 treated softwood frame with studs usually at 600mm centres with half height noggins fixed in load-bearing panels.
  • We include the supply of intermediate floors and roof structure as required

Pre-Insulated: (Optional Extra)

  • All External panels are pre-insulated with 100mm insulation, producing a U value of 0.21 W/m2, which is on average, 8 times more efficient than brick and block.
