Redwood Siding

redwood siding sap b greade Redwood Siding - Sap B Grade - nearly knot free
redwood sap B Redwood Siding - SAP & HEART wood contrast

The name REDWOOD adds value to your home just by saying it. Our Redwood siding is custom milled, pre-finished and delivered direct to your jobsite in pristine condition.
Buffalo Lumber customers have created a look like none other with Redwood simply because it's "over the top". One of our customers built a Redwood Timberframe home sided with Redwood Sap B grade using a semi-transparent stain to smooth the contrasting sap and heart woods. A second customer used a darker pigmented stain to emphasize the deep reds in his Pre-Stained Redwood Home sided with Redwood Heart "B" Grade.
Redwood siding has four distinct redwood grades - Clear All Heart (no Knots, no sapwood), CLEAR (no knots, both Heart & Sapwood), "B" Grade (nearly knot free - Heart & Sapwood) and STK (Selected for Tight Knots - heart & sapwood). Buffalo Lumbers "Near CLEAR" Sap B is priced below. Please CALL for STK and CLEAR Redwood prices.

Redwood SAP B "NEAR CLEAR" Grade
The contrast is why we love it!

Sap "B" is a quality redwood grade containing more sapwood, limited knots and other characteristics not permitted in All Heart B or Clear grades. Down one grade (and a few dollars per sqft) from CLEAR, Sap B "Near Clear" redwood grade allows a few small knots but preserves the beauty and appearance of this majestic wood.

Sap B Redwood Siding is known for the stark contrast in colors from the smooth creams of the sap streaks to the dark reds of the heartwood. The contrast is "absolutely magnificent" according to one of our customers who loved this wood on her pool house.

How Much is Your Peace of Mind Worth?

A FACTORY FINISH ensures a lasting, higher quality job than traditional "on site" stain or prime applications. Factory finishing costs about half the amount of field staining. Pre-finishing your cedar siding eliminates the problems of lap marks, shrinklines, streaking, color variation, and job site dirt pick-up.

During factory pre-finish all four sides of the board are completely sealed, ensuring total protection. Controlled temperature and humidity levels stabilize any moisture in the wood. The finished siding arrives at the job site totally protected from exposure to water and sunlight. Western Wood Products Association and the California Redwood Association recommend pre-finishing all wood siding including cedar and REDWOOD!
To get aTrue Finish Cost Comparison we interviewed the owner of a professional finishing company. If you are going to do the job right- you can't do it better (or cheaper) than the machines. If you are planning to stain instead of paint- the number of gallons needed per square foot virtually doubles. You do not have to apply a final coat to the face after installation but you had better have a large, well ventilated area with racks for the wood siding to dry - usually 3-7 days depending on humidity and finish choice.
FACT - When you call the first thing the Califronia Redwoood Association will tell you is that 2nd growth redwood siding needs to be sealed on all six sides prior to installation and then re coated as needed on the face for the lifetime of the wood. Their guide outlines the types of finishes they recomment on their site - CAL Redwood Exterior Finishes Guide

Why HEART Redwood?

As far as wood sidings go CAH (Clear All Heart) Redwood Siding is the best of the best. We have customers who want the wood to weather naturally without any preservative on it and All Heart Redwood is the only way to do that. You want an "All Heart" classification for maximum performance in tough climates with minimal maintenance. Clear All Heart Vertical Grain redwood siding (CAH VG) will last 30 years and still be beautiful.
With heartwood you can stain OR let the wood weather naturally to a color you like and then preserve that color with treatments. Redwood will turn a beautiful silver grey color when exposed to direct sunlight (it can also turn black in wet climates so that needs to be considered).

The PRICING of CAH Redwood
Mixed Grain, Vertical Grain, Tight Grain

The blunt part of the equation comes with the price of Heart Redwood. Once you have decided on all heart the next thing that affects price is the number of knots you can allow. The fewer knots the higher the price. The next price jump is the angle of the grain - mixed grain vs vertical grain. Vertical is rarer and Tight Grain - 9 or more annual growth rings per inch - even more rare and costly.
Sadly, the reputation for redwood's vaunted performance was earned during the clear cutting of 90% of all old growth redwood forests before the year 1960. The products made from these 2000+ year old trees had incredible performance properties due in no small part to the tightness of the annual grain rings.
Sustainable harvesting methods are intended to preserve the species survival while maintaining environmental balance. In order to achieve these goals the grade rules allow the use of products made from New Growth forests. New Growth are trees that grew in an area after logging or another disturbance which removed Old Growth trees. 2nd growth redwoods can grow very fast, in optimal conditions a redwood can grow as much as six feet a year or more. A forest in Humboldt Redwood State Park, logged 80 years ago reports New Growth trees that are nearly 200 feet tall today.
This rapid growth creates annual grain rings that are spaced much farther apart than old growth. A product made from old growth could have as many as 50 annual grain rings per inch. A product made from New Growth could have as few as 1 ring per inch.
If NO grain designation is made "Mixed Grain" is the standard. The visual variation in a "Clear All Heart" Designation with no reference to grain is striking in both color and consistency.

example of Clear All Heart Redwood Siding mixed grain boards

In the All Heart Redwood picture above the Appearance, Uniformity of grain and Texture of the grain varies from board to board. The boards I am pointing to are both vertical grain - the one in the center is tight vertical grain. The surrounding boards are mixed grain. This was a Redwood Heart Mixed grain order that included some Vertical Grain boards. There is usually some percentage of VG included with all mixed grain heartwood orders and you can select for a more consistent look by grading through your siding boards before you install.
If you want to preserve the red of the wood itself you can figure on re-staining every 3 or 4 years as needed. You will be able to tell. Here is a redwood sided house in Connecticut done in mixed grain Heart B redwood stained with Australian Timber Oil "Mahogany Flame". This is 1x6 T&G with a V groove. He used the smooth side of the board.
We have Redwood Heartwood in knotty (Con Heart) which allows knots every 6 inches on any given board and is pretty knotty. For knot loving customers it is not a problem. This is the most economical grade of heartwood siding. Next we have Heart B which is an excellent grade for people who prefer fewer knots but don't mind a few. Our Heart B allows one or two knots per board and has consistent runs of knot free boards. Then we have Clear All Heart which means no knots. This is the premium grade and the most expensive of the lot.

Our popular Redwood siding patterns include T&G, Bevel, Shiplap, Rustic Channel Lap and Dutch Lap - also called Cove or German Lap. The full spectrum of Redwood pattern diagrams and actual and exposed specifications are available and can be quoted upon request. Sizes include 1x6, 1x8, and 1x10" widths.

Redwood Grades

Redwood "Clear All Heart" (CAH) grade contains only wood from the heart of the tree and is the finest architectural redwood grade. It is free of all defects on one face. The reverse face is allowed slight imperfections. Our T&G, Shiplap and Channel Lap redwood siding patterns are reversable with one rough and one smooth face.

Redwood "Clear" grade is the same quality as "Clear All Heart" - the finest architectural heartwood grade - except that it contains sapwood in varying amounts and is allowed slight visual imperfections (which we consider character) on both faces. As far as allowable flaws and defect is concerned it is very similar to Clear All Heart - as far as resistance to moisture, rot and insects is concerned it is nothing like "all heart" redwood and needs to be protected in order to perform.

The other difference between CLEAR and CLEAR ALL HEART redwood grades is visual - the sap is bright yellow and the heart is deep red. The contrast can be striking. This contrast is beautiful to some (myself included) and this is the least expensive way to get the fewest amount of knots. You are giving up resistance and uniformity but you can augment resistance with technology and "tone" the contrast with stains.

Redwood Siding SQFT - LFT Coverage

Redwood siding is often sold by the linear (or lineal) foot. To figure out how many linear feet (LFT) of siding you need you must multiply the square foot area you need to COVER by a linear factor based on the siding width you have selected 6", 8", 10". The Lineal Foot Factor is derived by dividing 12 inches by the individual pattern's "exposed" face - the width that still visible after the siding boards are installed.

A) Calculate the square footage in walls: length x height = sq. ft.
B) Calculate, and then subtract, the square footage of openings
C) Add 10% to cover trim and waste = SQFT needed
D) Multiply SQFT result by the linear factor = LFT needed

BUYER BEWARE WARNING: The actual "dressed" widths and "Exposed Face" measurements below are based on WWPA industry standards book. However, some redwood mills use the California Redwood Association Lumber Patterns book.   BUT - independent of which pattern book is used - individual mills often have their OWN pattern standards which vary from the books (usually smaller). When you get ready to buy be sure to ASK for the exposed width to make sure you are buying enough redwood siding to complete the job!

SQFT AREA: 4 * 8 * 40 = 1280 SQ FT - 128 (10% openings) + 115 (10% trim/waste) = 1267 SQ FT

Common Sense Siding Installation Tips

The fact is that all wood no matter how it is dried (seasoned) will expand and contract during the year due to moisture changes in the air.

Allow your wood to acclimate before installation. This is the most common installation mistake and the most costly. When the wood arrives it will begin to change sizes to adjust to its new climate. The worst thing you can do is install siding during this phase. This is true of ALL seasoning grades. Allow 1 - 2 weeks for your wood to acclimate. The last thing you want to do is install it DURING the change.

Ideally you would unband the wood and sticker it for proper air flow. But if you do not have that option then leave it banded for a longer period of time. After this acclimation period size changes will be seasonal and minimal. This simple step is the single most important thing to remember when installing any wood siding product especially PAD board.

Avoid moving lumber when it is raining and it should always be covered with a lumber wrap that allows air to circulate moisture out. Always keep lumber on pilings so air can circulate under the pile. Never store lumber in a room with fresh concrete or drywall. Do not store the exterior project wood anyplace where it might be artificially heated or cooled. It must adjust to the natural conditions where it will reside.

Most wood expansion and contraction is across the width of the board. Selection of a Lap pattern minimizes the affect of that movement. Movement length wise is minimal. But to minimize gaps take the time to miter (angle) cut and treat the ends as you install and the results will last for years.
