What is osb wood

Conventional woodworking fixings and techniques can be applied to OSB which provides good holding power for screw fixings into the board faces; generally, edge fixing is not recommended. Parallel core screws should be used because they have greater holding power than conventional wood screws. A high ratio of overall diameter to core diameter is desirable. Drill pilot holes for all screw fixings. Fixings into the board face should not be within 8 mm of edges and 25 mm of the corners.

Nails and staples can be used for lightly loaded fixings or to hold glued joints while the adhesive sets. A wide variety of jointing methods can be used, provided the following simple guidelines are observed:. Use sharp cutters to avoid tearing or burnishing the surfaces to be bonded. Use a high solids content adhesive with low flowing properties such as polyvinyl acetate or urea formaldehyde. Locate mating pieces accurately and hold them under pressure while the adhesive sets.

The width of grooves machined in OSB should be limited to about one-third of the thickness of the board. The depth of groove is typically about one-half of the board thickness. Allow adhesive-bonded joints to condition for several days before sanding and finishing; this avoids the appearance of sunken joints and is essential with high-gloss finishes.

A tongue and groove joint is very efficient, provided the fit of the joints is not too tight to cause a split along the edge. When attaching lippings, the tongue should be machined on the solid wood piece c Finishing Where smooth surfaces are required pre-sanded panels should be specified.

Health and Safety a Dust OSB will generate dust when it is machined and this dust, like any other wood dust, is a potentially hazardous substance and must be controlled. Dust from cutting operations can be controlled adequately by complying with the Occupational Exposure Limit in the country of use.

Exposure must be reduced as far as possible below this limit, usually with properly designed and maintained dust extraction equipment fitted to woodworking machines.

Extraction equipment is often not practicable or even available when using portable or hand-held tools, so a suitable dust mask for example, Type FFP2 to EN should be worn. If possible, work in a well-ventilated place. Uncoated OSB manufactured using phenol formaldehyde or isocyanate resins does not require to be tested for formaldehyde and is automatically rated as E1.

Uncoated panels produced in Europe generally achieve an E1 rating. All rights reserved. About Us. What we do. Strategic priority projects. Recent achievements. Our members. Become a member. Managing board. Working groups. Wood-based Panel Industry.

Another advantage is that it gives the rooms a more natural look. Materials such as the cedar wood, corrugated metals, and the seamed metal are good options of roofing the sheath. The OSB board can be an addition to this list as it will add a more natural look. It is also a cheaper choice than the other materials.

However, the OSB is more vulnerable to weather elements as it absorbs moisture and bulge. To solve this problem the OSB can be treated with water-resistant materials. The OSB can be used in making furniture pieces such as chairs and tables.

Furniture made from plywood are dull and need painting. In such a case the osb board can be a better choice because they do not require painting. Your email address will not be published.
