Technical Shutter Information

 

Quarter-sawn louvres for beauty & extreme durability.

 

The finest heirloom furniture is made with quarter sawn wood to ensure generations of durability and so are all Norman timber plantation shutter louvres.

 

Shutter Technical Information

In quarter-sawing, the wood is harvested from tree logs in a way that makes it less susceptible to inherent cupping, twisting and warping. Cuts are made vertically through the tree, across and perpendicular to the growth rings which gives the wood remarkable strength and stability.

 

Though craftsmen recognise that quarter-sawn wood results in a superior plantation shutter product, flat-sawn wood is widely substituted because it is much more plentiful and inexpensive. Quarter-sawing yields fewer usable boards and are extremely prized for the manufacture of superior quality plantation shutters.

 

Quarter-sawn louvres reveal beautiful grain.

Quater-sawn wood enhances the Norman Timber Plantation Shutter range. The tight grain pattern showcases more depth and character than flat-sawn wood and the smooth surfaces result in an exceptionally smooth finish.

Growth rings are parallel to the short face. The long face of every board is close to a radial face. A large number of growth rings can be seen on this face.

 

Advantages of Quarter-Sawn Timber:
- Best grain shows on face
- Good wearing surface for floors, furniture
- Radial face preferred for coatings
- Lower width shrinkage when dried
- Less cupping and warping than other cuts
- Can be successfully reconditioned

Engineered Stiles For Stability

A well crafted plantation shutter closes solidly, does not have unsightly gaps and stays that way year in year out. To accomplish this, each part of the plantation shutter must resist twisting, bowing, cupping and all forms of instability inherent to natural wood.

Compounding the challenge is the fact that many plantation shutters require pieces of wood that must span over 1800mm.

 

Norman manufacture all timber plantation shutters using unique reinforced engineered wood stiles, employing an advanced procedure that bonds multiple layers of wood together with pressure, heat, and a proprietary chemical formulation. This provides an intense level of durability to the cores of the stiles and results in a robust support system for your plantation shutter panels.

Proper wood joinery is critical to the prolonged performance and quality of a plantation shutter. Norman Plantation Shutters recognise that the sheer and racking forces endured by plantation shutters dictate the need to use haunched mortise and tenon joinery.

 

Used where a maximum level of strength and durability is required, the haunched mortise and tenon joint will give the plantation shutter frame the highest level of stability and longevity.

 

All Norman timber plantation shutters are designed and manufactured with the ideal haunched mortise and tenon joints.

Prescription Wood Conditioning

 

Prescription Wood Conditioning Image 1The Norman plantation shutters patented wood drying techniques, originated in their research and development laboratories, and is used on the complete range of Norman timber plantation shutters.

 

Norman Plantation Shutters employ a prescription Wood Conditioning technique to reduce post installation shrinking and swelling on timber plantation shutters.

 

Drying to the proper environmental conditions ensures that plantation shutters will close tightly without gaps resulting in a more solid and beautiful plantation shutter for years to come.

Phoenixwood An Environmental Wonder

Phoenixwood trees improve the microclimate by reducing the effects of drying winds and increasing air moisture during the dry season, by absorbing underground water from deeper layers and humidifying the air by transpiration. The huge leaves of the Phoenixwood are sparse, allowing plenty of light to come through, thus food crops receive light at all times (around 20% - 40% light penetration).

 

Besides the extraordinary benefits of growing Phoenixwood, all parts of the trees can be used for commercial purposes. This is another reason why many species of Phoenixwood are successfully used in agroforestry.
