Underlayment is a structural board that is primarily used as a subfloor. That is also where it gets its name. But in the meantime, the board is used for many more applications. Think, for example, of walls and roofs. This underlayment variant (C+/C-) was developed for constructive purposes.

Underlayment Elliotis pine panels ordered online

Underlayment Elliotis pine is a construction board that is primarily used as a subfloor. This is how it got its name. But because the plate is so strong, it is also often used for walls and roofs. Underlayment has moisture-resistant properties, making it more resistant to moisture than birch plywood.

Order your sawn-to-size Elliotis pine panels easily online. Underlayment can be sawn or milled into various shapes. The most popular shape is a rectangle, but we also cut circles, ovals, hexagons or even parallelograms to size. Do you want your do-it-yourself project neatly finished? Then choose one of the available (edge) finishes.

Underlayment Elliotis Pine: What is it?

Underlayment Elliotis pine is a plywood made from pine wood. Underlayment has a number of unique properties compared to other panel materials. This plate material is very strong, resilient and can carry a lot of weight. The slight markings of the softwood give it a natural look. Our underlayment sheets are only suitable for horizontal applications, such as table tops, window sills, etc. These boards are not suitable for vertical projects such as doors and room dividers.

Like other types of plywood, underlayment Elliotis pine consists of several layers of wood veneer. These layers are glued together crosswise, making the board very strong but also putting tension on the board. During sawing and machining Underlayment Elliotis Pine C+/C-, tension can be released which can cause the boards to have a warp.

The direction of the wood grain

With underlayment, a wood grain is visible. The drawing of the wood grain always runs lengthwise. When sawing the board, we maintain that the length measure is also the length direction of the wood grain. So pay attention when filling in the dimensions, so that the wood grain runs in the right direction!

Visibility quality underlayment C+/C-

The quality of the top layers of plywood is indicated by letter combinations. There is a letter indication for the visible side (top side) and one for the reverse side (bottom side). This refers to the quality of the cover veneer; the quality of the gluing, for example, is indicated differently. B/BB is an example of a common quality, which can be used for decorative applications. The first letter (in this case B) indicates the quality of the visible side and the second letter (in this case BB) indicates the quality of the reverse side. Read hier more about all visible qualities.

This sheet material also has two viewing sides. It is denoted by C+/C-. The top side has view quality C+. C+ quality indicates that more defects are allowed in the veneer, and that any allowed defects such as open brush holes have been repaired. This veneer is the lowest quality underlayment and is only suitable for structural purposes. Often these veneers are plastered shut with a filler, rather than stuffed. Cracks are allowed and fallen-out knots are also allowed. The underside is even coarser, this has the visibility quality C. With C-grade veneers, they are not suitable for decorative applications because of the permissible defects that are not repaired. Also, this side is not sanded. Constructively, this is still a good board and is therefore often used as a construction board or packaging material.

Available thicknesses of Elliotis pine underlayment

Elliotis pine underlayment can be ordered in different thicknesses. You can easily specify your desired thickness during the ordering process. That way, you can be sure that the panel material meets your requirements: both the format and the thickness of the material. The following thicknesses are available: 9 mm, 12 mm, 15 mm en 18 mm.

Machining of underlayment Elliotis pine boards

Whitewood is easy to work with. Please note, however, that this board material discolours over time. Use an oil, varnish or stain to counteract discolouration. Lightly sand the material before varnishing. The ends may contain splinters, so give them extra attention. Finally, you can treat the ends with an edge sealer, because they are very rough. It is also important to pre-drill the sheet material. The sheet material can split.

Specific applications of Elliotis pine underlayment

Underlayment Elliotis pine is a structural board with a low visual quality. This means that we do not recommend using this board material for visible work. It is, however, extremely suitable for floor covering, construction work or other projects where the material must be strong, but not visible. Use the material indoors only, to ensure long-term enjoyment of the board material.
