Fig A: After Build
This image shows the corner of the building as
assembled after the nal stage. The back board
(highlighted) is xed to the framing so that causes the
boards above to remain at that height.
Fig B: Timber Movement
This image shows an over exaggerated image of
possible timber movement. As you can see the back
wall board (highlighted) has not moved, but the
boards below have, due to the drying out of the
boards and the weight settling.
This if left alone could cause a gap in the walls. There
is a solution and way to prevent this happening (see
Fig C). The following rule generally applies:
- Excessive dry conditions can cause board shrinkage
- Excessive wet conditions can cause board expansion
Fig C:
We suggest that removing all the vertical framing
temporarily will allow the building to re-settle and
nd its natural level. This includes all items holding the
vertical height (Framing, Window and Doors Frames
etc.) as well as any xed cupboards etc. Simply by
doing this the building will re-settle and close any
gaps.
Fig D:
Re-x all the vertical framing to cover where the
boards meet. In some instances the framing may
require minimal trimming to t. Checking the building
regularly will ensure that this movement is minimal.
We recommend checking and re-treating the building
a couple of weeks after the build and bi annually, if
there are particular dry or wet periods extra vigilance
is always advised. Please contact our support team ifs
you need further reassurance or assistance.
Maintenance: 2 weeks after build & on-going - Due to the nature of timber and the Interlocking style the building will want to settle and move. Follow the stages for the explanation of timber
movement and the prevention/solution of issues.
