BELLAWOOD  3/4" x 4" Natural Ash

A:

This is a random length wood product that comes 1’ to 7’ in length, the average length is about 2.5'. Thank you for your inquiry.

A:

This is a solid 3/4" product designed to be nailed to a wood substrate.
But can be installed over concrete using our Elastilon underlayment.
What you should know about Elastilon Strong
An Elastilon-backed wood floor is much faster to install than traditional nail or glue-down methods.
Elastilon Strong can be installed on new concrete floors, handling up to 3.9% moisture content. A vapour barrier of at least 6 mil PE should be used below grade and on newly poured concrete above grade where the moisture content is above 3.9%.
Laid down with a 5/8” (15 mm) expansion gap, Elastilon Strong creates a dynamic, floating floor that expands or contracts naturally with the hardwood.
Elastilon Strong has no odor and is free of volatile materials.
Elastilon Strong gives cushioned comfort.
1/8” (3 mm) thick Elastilon Strong has ratings of IIC 62 and STC 54.
Thermal resistance: R _ 0,15 (m K) / W
Elastilon Strong carries a 70-year limited warranty. Thank you for your inquiry.

A:

All wood species can change color over time due to oxidation or when exposed to light. In some species, the change can be more dramatic and may darken in color over time, while others tend to lighten. Currently there is no known value set for Patina or color change of a species so contractors and or customers should be aware of this normal condition. The patina process is unrelated to the urethane finishes. Thank you for your inquiry.

FROM THE INSTRUCTIONS
Working With Thinner Boards- Although these instructions are common to the installations of Elastilon with all hardwood floors, particular attention must be given to the following when installing thinner boards. (i.e., ½” / 12.5mm, 3/8”/10mm and 5/16”/8mm)

• All end joints must be glued throughout the installation.
• The floor must be flat to within .08 inch over 8ft (2mm over 2.5m)
• Expansion room must be maintained around all walls and obstacles.

Ash is about 3% more stable than red oak, between it's stability and 4" width it may not be the best choice. In other words you may experience some shrinking especially in cold months.

Note: the 1/2" plywood isn't sufficient, a minimum 5/8" plywood subfloor is recommended for naildown installations.

As you may know, some wood species are better candidates for radiant heat (RH) installations that others, if you prefer solid wood floors, choose a #species known for its *stability. Here is the order for best floor type selections as recommended by the National Wood Flooring Association (NWFA)

Floating wood floors and laminates - are highly recommended because they tend to move as a total unit better accommodating moisture and temperature changes.

Engineered flooring - works well with radiant heat because of its dimensionally stable plywood construction. This construction allows each wood layer to run perpendicular to the other thereby resisting movement and moisture fluctuations.

Quarter sawn or rift-sawn flooring – this cut or style of flooring is preferable to Plain sawn because it will expand upwards and downwards from elevated moisture- not side to side, producing less gapping and board edge cupping.

Strip flooring - is also a better choice than plank flooring, because narrow boards expand and contract less than wide boards do because there are more seams in a floor to take up or allow for any excessive board movement.

If you choose to use solid boards or planks wider than 3" make sure the board moisture content is dry to around 6-9% before and maintained well after installation. For any wood application over radiant heat, the newly installed system should be operating some two weeks prior to the floor installation, this helps to further dry out any unknown pockets of trapped moisture. Acclimation is critical with radiant installations to prevent board shock. In no case should radiant heat surface exceed 85 degrees. Maintain in-door 30%-50% humidity and temperatures of 60˚- 80˚

Common red and white oak have been used successfully over radiant heat. Ideally, species 15% to 20% higher in stability than red oak are considered best choices. See our Stability chart for boards listed on the higher stability spectrum. Brazilian Cherry is more stable than red oak, however we do not recommend this species for radiant heat applications. In some instances sustained high heat can have a negative impact on this species. The natural oils, calcification and other properties of this species can slowly migrate to the surface just under the clear top finishes manifested as small whitish oxidation spots. Calcification is a species characteristic, not a defect. Calcification cannot be sanded out. Therefore after installation, individual boards manifesting this condition can cut out and be replaced with new boards.

Good species for radiant applications are;
Australian Cypress, Bolivian Rosewood, Koa, Mesquite, Teaks, Blood wood, and Mahogany. Poor performers are Maple, Beech and Birch.


*Wood stability refers to a measured amount of movement that can be expected in some species after installation. Species stability is directly related to local humidity, temperature and surface moisture, therefore acclimation for radiant heat in very important for a successful installation.

#Note that even when using an ideal species for Radiant applications actual wood performance can still vary due to the Radiant system construction, installation Techniques, as well as your region of the country.

A:

Most all pre-finished solid wood floors will have a bevel to prevent chipping of the edges and overwood issues. We have do have square edged laminates and vinyl planks that may be of interest to you.
Thank you for your inquiry.

A:

Ash is 2% harder than red oak. It's not soft but like any hardwood flooring it can dent. Yes it can be refinished. Yes it's 4"

Please call our Customer Service Dept. @ (800) 366-4204 for help with this question.

A:

You will get a mixture of both sapwood and heartwood. We cannot guarantee you will get predominantly more heartwood.
