Does Plaswood expand with temperature change?
Plaswood is similar to most other composite materials, if the temperature increases then so will the “timber”. For example, Plaswood joists have a maximum linear expansion of 0.109mm per metre per degree Celsius. So, boards cut at 15 degrees Celsius would have a probable maximum of 40 degrees, (40 -15 = 25 x 0.109) X (3.1) = (2.725mm x 3.1) = 8.4475mm expansion. 
How to saw Plaswood 
Circular blades with crossed teeth have been found to be the most suitable. The Plaswood manufacturer suggests a saw speed between 2,000 and 4,000 rpm. Sawing is best done from the presentation face (the side that will be seen) and cut through to the back face of the profile.
Can I drill into Plaswood?
Twist drills are most efficient but standard spiral bits can also be used. Drills with speeds of 400 - 900 rpm are better than high-speed drills. Holes are best placed 10mm plus from the profile edge.
Remove waste material and pause occasionally to allow the drill bit to cool.
What is the best way to join Plaswood?
A joint may incorporate more than one method of fixing. Finger type and mortice and tenon or birds-mouth type joints can be made using standard wood working machinery with the appropriate cutters.
What fixing to use with Plaswood
Twin flight, parallel thread, coarse pitch screws, similar to those used with wooden particle boards or hi-low screws, have been found to be more reliable than conventional taper thread wood screws.
We recommend that all fixings are made from stainless steel/brass or are plated, to retain the integrity, long life, rot free, maintenance free, quality of the final product.
When bolting or screwing profiles together, the pilot hole must be larger than the bolt. Elongated slots are recommended to facilitate temperature related expansion/contraction of the material.
Can Plaswood be stapled?
Due to the compact surface it is more difficult to penetrate Plaswood than wood. Stapling has been found to be an effective method for applications such as wire mesh fencing fixing but pneumatically powered guns would be recommended  by the manufacturer for use on these types of fixings.

Can Plaswood be planed?
Standard industrial timber planing tools can be used. The finish depends on the condition of the blade, feed rate, cutting speed, clearance and cutting angle.
Is Plaswood as stiff as timber?
Recycled plastic is more flexible than wood or metal. All product and structure designs facilitate this technical characteristic (e.g. maximum distance between fence posts), furthermore, all of our products are supplied with installation or fabrication recommendations.
How to store Plaswood?
Direct sunlight may affect profile alignment and cause profile distortion. To prevent profile bowing profiles should be stored on a flat surface, strapped in batches.
