The guideline stock quantity shown is what we aim to carry on stock, but is not necessarily exactly what we have in stock. We use this setting for items where keeping accurate stock levels between the website and our physical shop is difficult. If we cannot meet your requirement from the actual present stock, we will let you know ASAP along with a timescale of ordering. If we can cover your order from stock, it will be sent on your chosen delivery service as normal.

  • Firrings strips are used on flat roofs to create a slope for the rain to fall off.
  • This is for one single length of firring strip.
  • They are designed to be fitted on top of each joist.
  • Length of 4.8m x 44mm wide.
  • Untreated timber.
  • 91mm to 2mm is the fall.
  • The fall is 1:54 which is greater then the usual standard of 1:80. Giving more fall.
  • These can easily be cut down to your desired length, below is a quick chart to let you know the height at the various lengths.
  • NOTE: The thin end may break during delivery. The thin end is susceptible to breaking in delivery, but as they are designed to be fixed on top of each joist, this is of no detriment if the product is in pieces rather than the full length, as the slope will still be created.

Sizes are approximate as we haven't actually cut them. The sizes below are if you cut from the thicker end.
