The heartwood of naturally durable species such as western red cedar, yellow cypress and white cedar will all resist decay to some degree, but it is variable. The amount and type of natural fungi-toxic chemicals deposited in the heartwood determine how durable the wood is. The sapwood of all species is considered non-durable. Heartwood of second growth may be less durable than the best of the old growth but probably less variable.

Wood is extremely durable. Many historic buildings have wood windows, properly treated and maintained, which have lasted hundreds of years. Especially when you understand the engineering side and build them well. A European wood

Douglas fir, southern yellow pine, and western red cedar are now available. All common sizes and most construction species of lumber and plywood (of any thickness) can be treated by Thermex-FR.

Treated wood is necessary if the wood is expected to stay wet for extended periods of time or is contact with the ground. Guidelines to define "extended periods" are under development at Forintek. Treated wood is also recommended if wood is used in an area of termite or wood-boring beetle activity.

Yes, all are highly rated for natural decay and disease resistance by the Forest Products Laboratory. Pressure treatment deeply protects wood against water and insect damage and pressure treated Pine is perfect for any climate. Cypress grows in southern swamps and is naturally resistant to water and insect decay by producing the compound "cypressine".

Wood Hoops are designed to bear abuse as the end grains (the hardest part of the wood) are all pointed vertically so to withstand the strikes by the drum stick shaft (the softest part of the drum stick). Also, the edge of the Ayotte Wood Hoop is unique engineered and shaped such that the impact of the drum sticks is evenly distributed throughout the entire surface of the hoop.

Some people need a particular species of wood, because they are matching to an existing floor. When matching to an antique floor, it is particularly important that you order flooring that will be milled from material that was cut at the same time as your existing floor. This means making sure that your new flooring is coming from original growth and not new growth trees. We also want to make sure that we match the species that you currently have.

This varies depending upon what part of the country you are in. Pressure Treated lumber is usually Hem-Fir in the West and Southern Yellow Pine in the East and South. The framing lumber is also regionally dependent. It can be Douglas-Fir, SPF (Spruce-Pine-Fir), SYP (Southern Yellow Pine) or Hem-Fir. The roof trusses can also be a variety of the same species, but will usually have msr (Machine Stress Rated) lumber for chords.

Woodfold Roll-Up Doors are offered standard in Maple, Birch, Cherry, Mahogany and Oak. We also offer other hardwood species on special request, though due to quality standards, we don't offer softwood species.

All lineal mouldings are stocked in Poplar; some also in Red Oak. Hand-carved woodcarvings are available in Lindenwood, with some also in Maple and Cherry. Custom species are available upon request - see "Our Services" for list of custom species.

We can utilize most any species that is suitable for structural purposes. However, we often use Douglas Fir because it combines beauty and structural strength comparable to many favorite hardwoods without the shrinkage and weight issues.

We build over eighty percent of all Kodiak Log Homes out of Engelmann Spruce, it has a good strength to weight ratio, is a beautiful blonde wood and is native to many dry climates. We also build many log homes out of Douglas Fir (attractive grain colour and superior structural strength) , Yellow Pine (full of character), and Western Red Cedar (attractive color in the grain and a natural resistance to insects and decay) for an up-charge of fifteen to thirty percent.

We work with oak, poplar, maple, and cherry on a regular basis. Other hardwoods are available as limited basis.

We offer the most common hardwood species including maple, mahogany, cherry, walnut and oak. The wood keys are sold by the linear foot, to be cut to size by the customer, or on a special order basis pre-cut to size by Hoffmann. Lead-time for cut-to-order wood keys is usually 4 - 6 weeks. We can manufacture wood keys in species other than the ones listed, please call for details.

If you can supply us with this information, we can help you decide on a starting point for your spine selection. We ask for this much information because, "Anyone you ask can GUESS at what spine you need, but the more information you give US the more EDUCATED that guess can be." The standard string material, B-50 is requires no extra "figuring". A fast flight string requires a jump in spine of 5-7 pounds. The Artificial Sinew string is heavy, thick, and stretches very much.

Treated wood can last virtually as long as you want it to, given the correct specification, quality control and installation. For example, service lives of over 60 years have been documented for treated fence posts in ground contact. However, as with any product, incorrect specification, inadequate quality control or major errors in installation can result in service lives less than expected.

Screws cannot be hot-dipped galvanised but are generally available in stainless steel. There are other types of coated deck screws on the market for decking.

No. The finishing properties of wood treated with waterborne preservatives such as CCA or borate depend primarily on the wood properties, not the preservative treatment. However, you'll get more life out of your wood finishes, and especially stains, when you're using CCA-treated wood. CCA-treated wood contains chromium, which is known to decrease the effects of weathering. The effects of the newer preservatives (CA and ACQ) are unclear.

The outside of a wooden hot tub doesn't require any type of treatment and nothing is required to extend it's lift. If desired for an aesthetic look, painting, staining or some other finish can be applied to match a surrounding deck. Nothing should be applied to the inside of the hot tub.
