Alaskan Yellow Cedar – Rain Screen Application

A recent project by Kreider Construction, we supplied the 1×6 Clear Alaksan Yellow Cedar for the siding that was installed as exterior siding and Rain Screen.


What is a Rain Screen?

In the quest of finding better moisture management and energy efficiency, some architects and builders are turning to “Rain Screens” as a solution.  A rain screen provides infrastructure to hold a building’s siding away from the weather resistant barrier.

By creating an air cavity between the moisture barrier and the siding, this double wall construction uses the outer layer (the buildings siding) to keep the rain out, while the inner layer (an air/moisture barrier) provides thermal insulation and prevents excessive air leakage.   It also allows any moisture that may pass thorough the siding to easily drain away, as well as accelerates evaporation of any residual moisture within the walls.

Although rain screens cost more than more traditional U.S. methods, they can prevent costlier problems and add green benefits to your project.

Alaskan Yellow Cedar   

alaskan yellow cedar

An increasingly popular choice for exterior siding, Alaskan Yellow Cedar has the same insect and rot repelling tannins and oils as Western Red Cedar, but is heavier and more dense giving it excellent strength and stability with very little shrinkage.  Its most popular characteristic, however, is its beautiful, pale yellow color.   Left untreated, it weathers to a very attractive light silver grey.  Pinkish or blueish stains that may appear on Yellow Cedar are not a wood defect or problem, but are from naturally occurring oils that come to the surface during the manufacturing process that will disappear after exposure to the sun.

Why Wood?

Environmental Benefits of Wood  cedar lumber

“One of the best ways to address climate change is to use more wood, not less. Every wood substitute – including steel, plastic and cement – requires far more energy to produce than lumber.”

- Dr. Patrick Moore, co-founder of Greenpeace.



  • Wood is the only 100% renewable resource in the manufacturing of building products.
  • Wood is the only naturally recyclable and biodegradable building material.
  • Wood has the lowest environmental impact compared to other building products such as steel, concrete, tile, vinyl siding, fiber cement siding, and stucco.
  • Wood products require less embodied energy. This is energy used in the extraction, production and transportation of the resource.
  • Wood products require little to no fossil fuels (a non-renewable resource) to produce.
  • western red cedar logsWood products produce less air pollution.
  • Wood products produce less water pollution.
  • Wood products generate less greenhouse gases. Wood reduces carbon emissions while concrete and steel increase carbon emissions.
  • Carbon Dioxide (CO2) is considered a contributor to Global Warming – Beyond Old Growth Trees that actually emit more CO2 into the air, young and mature trees actually reduces CO2 from the atmosphere.
  • Wood products are better insulators in homes and buildings which reduces the energy consumption in both heating and cooling making it the most energy efficient material. Wood is 400 times better at insulating than steel and 15 times better than concrete.
  • Wood products produce less solid waste – both in manufacturing of the products and at construction sites. There is virtually no waste in manufacturing wood products.

  • Wood products produce less solid waste – both in manufacturing of the products and at construction sites. There is virtually no waste in manufacturing wood products.
  • Wood products have the lowest ecological resource use index. This means that while trees are harvested the effects are only short term as reforestation follows. Other products have long term effects as their resources are non-renewable i.e. petroleum for plastic and ore used in steel and aluminum siding. Once these non-renewable resources are gone they cannot be replaced.
  • The trees themselves are produced naturally through solar energy.
  • Wood can be re-used and recycled with very little additional energy. Concrete cannot be re-used in the same form but can be down cycled to aggregate with a lot of additional energy expended.western red cedar being harvested
  • No other building product is more environmental than wood as demonstrated in “ATHENA’s life cycle assessment” research and study. From the growing of the tree to the disposal of the wood products, wood has a minimal environmental footprint. Non-renewable products such as steel, aluminum and concrete use up to 250% more fossil fuel energy from the production to the disposal vs. wood.

Western Red Cedar Care & Maintenance

Can you feel it?  Spring is COMING!  Time to start thinking about getting your outdoor space tidied up and ready for out door entertaining!


by written by the Western Red Cedar Lumber Association

The surfaces of finished Western Red Cedar decks, siding and trim boards exposed outdoors inevitably become dirty and can also be discolored by mildew, algae and moss. These natural elements slowly erode the finishes and as a result, all finishes applied to cedar require regular cleaning and maintenance to perform. The degree of maintenance depends on local climatic conditions, the type of finish and end use (deck or siding).

western red cedar decking



Western Red Cedar enjoys a well-deserved reputation as a wood that takes and holds a range of finishes for extended periods. Nevertheless, the usual lifespan of a finish will be shortened by degradation and discoloration. The causes of discoloration often require remedial treatment.


Dirt is the most benign cause of discoloration. A periodic cleaning with a mild, non-phosphate detergent solution will usually restore the surface finish.


Mildew is a common form of discoloration of paints and stains caused by staining fungi. Re-staining does not solve a mildew problem. When it is time to refinish, clean off the mildew with a mild bleach solution (oxygen bleach is preferred) or commercial mildew-remover. After the wood has been thoroughly rinsed and allowed to dry, refinish with a coating that contains an effective mildewcide.

Tip: A simple test for the presence of mildew on the coating can be made by applying a drop or two of a fresh solution of liquid household bleach (containing 5 percent sodium hypochlorite) to the stained area. The dark color of mildew will usually bleach out in 15 to 30 seconds. Discoloration that does not bleach is due to other factors and requires further investigation.


Discoloration due to extractive bleeding is usually caused by moisture. To stop stains caused by extractive bleeding, the moisture source must be eliminated. Mild staining is often washed away by rain over a period of weeks. In sheltered areas of a building where the stain persists, it may become darker with age and more difficult to remove. If washing with a mild detergent solution does not work, applying a mild oxalic acid solution has been proven to be effective in removing water, tannin or iron stains. Commercial cleaners are also available. If the stain remains, prime the area with an alkyd primer and top coat with a latex coating.


Iron stains may appear in two forms: the reddish brown discoloration caused by rust, and blue-black discoloration caused by the reaction of iron from nails and other metal objects with extractives from the Western Red Cedar. To prevent these stains, use only hot-dipped galvanized, aluminum or stainless steel nails when fastening cedar. To clean areas affected by iron stains, use a commercial cleaner. In situations where the stain has penetrated the wood surface, light sanding or brushing may be required.


These often occur in combination with extractive bleeding and mildew growth. These stains can be difficult to remove. Scrubbing the wood with a dilute oxalic acid solution is sometimes effective.

Caution: Handle oxalic acid solution with care as it can be harmful – carefully follow the instructions.


Chalking, the release of pigment and degraded resin particles, results from weathering of the paint’s surface. It is a degradation of the paint film, not the cedar. Chalking is a common cause of fading in tinted or colored paints.


Paint failure such as peeling, blistering or flaking is often associated with moisture build-up behind the paint and poor adhesion of the paint film to the underlying wood. This problem is exacerbated if paint is applied to weathered wood.


A deck that dries after wetting will last longer than one that stays damp. Ongoing maintenance practices for cedar decks include: allowing proper water drainage; keeping the surface free of dirt, leaves, tree needles and other debris; moving planters, benches and other deck accessories from time to time to permit the deck beneath them to dry thoroughly and ensuring that the ventilation under the deck is not inhibited.

Siding Choices

One of the most defining elements to any home is the exterior siding.  With a wide variety of styles readily available or custom made in Western Red Cedar, we invite you to learn about and consider a few of the most popular styles.

Cedar siding



Economical and beautiful, bevel siding is the most widely-used Cedar siding type. It is produced by re-sawing lumber at an angle to produce two pieces thicker on one edge than the other.  Depending on customer preference, it is provided with either a smooth or textured face in both clear and knotty grades.

Bevel siding is installed horizontally to provide a shadow line which varies with the thickness of siding selected.

Available in many widths and thicknesses, this is one type of Bevel Siding

Available in lengths up to 20 feet, Finger-Jointed Bevel Siding is an attractive and very cost effective choice when paint will be applied; providing all the performance and beauty of premium cedar siding.



A perfect complement to your rustic home at a fraction of the price of building a log cabin, as the whole log is not used.  This siding is manufactured with a flat back that makes installation over traditional structures easy and cost effective with beautiful results.  Log sidings are available in different sizes, in both Western Red Cedar and Spruce, and can be pre-stained to save money and time on the job site.

log cabin siding



Board-and-batten siding is created when wide clear or knotty Cedar (or other material) boards are installed vertically with narrower boards, called battens, installed vertically over the joints.  There are endless combinations of board widths that can be used to create this classic siding pattern suitable for large or small scale applications; the most frequent being 1×3” battens with 1×10” or 1×12” boards.  Additionally, the installation of the boards can be reversed with the wider boards installed over the battens to create a deep channel effect.

A cost saver when using this siding choice can be achieved by using “green” or unseasoned Western Red Cedar.



Tongue and groove siding is created by boards that have been manufactured to have one protruding rib (tongue) on one edge and a groove on the other edge, so that the tongue from one board fits into the groove on the next board.  By far the most versatile siding option, Western Red Cedar Tongue & Groove siding can be installed horizontally, vertically or diagonally.

It is available with rough or smooth faces in various widths and thicknesses, as well as grades and patterns, including ones that when installed create a slight groove between the two pieces.  There are many readily available styles “off the shelf” with the possibility of creating endless custom patterns.

Lap siding, available in many width and thicknesses, is manufactured to have grooves on both sides that allow the boards to be installed over each other to create a waterproof barrier.  Lap siding expands and contracts with changes in temperature without cracking or buckling, which makes it a very desirable siding choice in colder climates.

Channel siding is a popular type of lap siding that has a ½” overlap and a 1” to 1-1/4” reveal that when installed creates a channel between the boards.  Normally supplied in unseasoned, Western Red Cedar knotty grades, this product is commonly used when a rustic appearance is desired.

Because of the overlapping properties (one end of the board has a recessed area along its rear which receives the shaped top-rear end of the board next to it) it provides excellent weather protection while allowing for dimensional movement when installed vertically.  However, it may also be installed horizontally or diagonally.  Clear grades are manufactured to order.

Storage and Handling

  • Keep your decking clean, dry and out of direct sunlight before installation and finishing


  • For optimum results, seal decking with a high quality penetrating sealer, such as Penofin Hardwood Formula, on all four sides prior to installation if possible
  • Due to the extremely dense properties of this wood, a second field coat is recommended after “seasoning”
  • Use care when applying any finish to wipe away any excess.  Do not allow too pool or drip.  For more tips on application, please visit the Penofin website
  • Should you wish to allow your decking to weather to a beautiful silver patina, no finish is necessary
  • No need to wax ends

Ventilation and Air Flow

  • Check and follow all local building codes!
  • Allow adequate ventilation for proper air flow to reduce cupping and checking potential
  • For maximum long term stability, install deck with a minimum ground clearance of 18″ with at least two sides of the deck open
  • In all cases, it is absolutely necessary to have at least 50% unrestricted air flow
  • Create a slope for drainage so there is no chance of standing water
  • If a minimum ground clearance of 18″ is not available, it is recommended to use 5/4×4″ decking


  • Our mahogany decking is kiln dried.  Unlike air dried boards, shrinkage is very limited.  However, excessive moisture may cause the boards to expand slightly
  • Install 6″ decking (5-1/2″ net) with a minimum gap of 1/4″ between boards.  4″ decking (3-1/2″ net) should have a minimum of 3/16″ between each board
  • In more demanding applications, such as boat docks, decks build closer to the ground and decks with less airflow, a minimum of 5/16″ for 6″ decking and a minimum of 1/4″ for 4″ decking is required
  • This decking does not shrink or expand end to end, so neatly trim ends and butt together

  • Pre-drill pilot holes and countersink screws.  We recommend using stainless steel fastners and have Smart-Bit countersinking tools available to help
  • Face screwing or edge screwing are the most effective methods of installation.  Color matched Headcoat Stainless Steel Screws are available  and provide beautiful results time and time again
  • Hidden clip fasteners and nails are not recommended and my void warranty

Maximum Allowable Decking Spans

  • 1×4 and 1×6   ~   16″ on center
  • 5/4×4 and 5/4×6   ~   24″ on center


  • Though we have had no reports of irritation of any kind with this hardwood, we still recommend wearing protective eye wear, dust masks and gloves during installation
