Specifications for Architects and Builders

About Macrocarpa


MacDirect is specified on Productspec and Smartspec for architects and builders convenience, with detailed specifications for cladding, structural /framing and internal lining/joinery where cypress (Macrocarpa) is specified. 

Highly sought after as a decorative and building timber, Macrocarpa has a golden brown heartwood with a speckled lustre, which is rare in timber. It’s a low- to medium-density softwood that looks and works like kauri, is durable outdoors and can be used without any preservative treatment.


Freshly cut Macrocarpa timber has a fragrant spicy odour, which is typical of cypresses. It is a very stable wood, is easily sawn and has relatively low surface hardness, with good working and finishing characteristics and relatively uniform wood properties. 

Macrocarpa can be used for interior uses

  • ceiling sarking
  • exposed beams
  • flooring
  • wall panelling
  • framing
  • furniture
  • solid wood bench tops
  • architraves
  • skirtings

It is not recommended in-ground for construction purposes (including in-ground posts for fencing, decking and pergolas).

Brief outline of Macrocarpa qualities

 

Durability

  • Both the heartwood and sapwood of Macrocarpa are naturally borer resistant (Anobium) for interior housing purposes.
  • The heartwood is moderately durable for above-ground purposes, but the sapwood is non-durable.
  • The timber cannot be pressure treated with copper, chromium and arsenic (CCA), but sapwood can be boron diffusion treated to resist insects (but not decay).
  • Heart Macrocarpa is rated similar to H3.1 treated radiata pine
 

Strength

  • Macdirect framing timber has been shown under test to meet the specifications of SG8-SG10. However at present MacDirect is not accredited to sell verified SG8 structural timbers.
  • MacDirect structural timber is visually graded to No.1 Framing grade which qualifies as VSG6 for engineering purposes.
  • Macrocarpa is a low to medium density softwood that looks and works like kauri.
