MDF is a wood product made from wood pulp. This results in a very dimensionally stable material that has no pitch pockets, sap streaks, grain tear out or knots. This makes an ideal surface for painting.

HDF and MDF are man made products, manufactured from the waste thinnings of trees. Basically, hardwood and softwood chippings that would otherwise be discarded. They are then blitzed with resins in a huge blender and then compressed under massive pressure to form a dense sheet material. HDF stands for High Density Fibreboard, and MDF Medium Density Fibreboard. This process produces a very stable , strong and workable material.

We do not use Chipboard or Melamine. We often use MDF; mostly for internal surfaces and especially for the superior finish on painted furniture. We are happy to accommodate clients' wishes and can quote for ply, blockboard or solid wood as substitution materials.

We no longer sell MDF shutters. While similar in appearance to a solid wood shutter, we found they had two major drawbacks; the weight of the panels resulted in them sagging in the middle especially when hinged together and also screws tended to pull out because of the pressure on them and then didn't re-thread

a wood product, its usage is quite similar to solid wood. A list of suggested tools and techniques are included in the product installation guide.

We only use pine professional stretcher bars that are industry standard. We consider MDF blocks with fabric glued to them to be far too heavy and inconsistent with quality canvas stretching workmanship.

There's a huge debate on this one. MDF is know to be seriously bad if inhaled as the sawdust is extremely fine.

In internal CMI bucket testing, Extira exhibited substantially smaller edge cracks after exposure and air drying than Norbord MR and Medex NC. Call CMI Marketing for test details at 1.866.382.8701. Caliper swell when saturated in water improves 1-1/2 to 5 times comparing Extira to MR grade and typical MDF. CMI manufactures another product, MiraTEC Trim, using the same ingredients and manufacturing technology which has performed exceptionally well on the market since 1998.

Yes! Rub-R-Wood© can be sanded and cut. It can be installed with an air gun or be predrilled and nailed. Nails should be kept 6" apart and 3/8" from any edge.

MDF is run on production line for high efficiency. Rub-R-Wood© is made to order for each customer. Cost of materials is another major factor.

MDF and hardboard produce dust which is much finer and more readily dispersed than dust from solid wood, plywood or particleboard. MDF must not be machined in schools unless all occupational health and safety issues are addressed; including the use of WorkCover NSW approved extraction system. Schools generally do not have facilities to control the hazards from dust created when MDF is machined. The risks associated with the use of manufactured timber products are significant.

Birch plywood will be perfectly satisfactory if of the same thickness. High quality ply should be used as it is important to use a board with no voids or gaps in the material.

The Health and Safety Executive (HSE) has concluded that machining of MDF is no more, or less, hazardous than working with other forms of wood. In short, formaldehyde is not considered to be a problem. The HSE has previously suggested that an FFP2 respirator could be evaluated for cutting or routing MDF in ventilated workshops eg. 3M™ 8822 / 9322 Respirators.

Pateco HDF is typically more durable, resists shrinkage and swelling due to seasonal changes. The difference is in the type of resin used in making of the board. Mostly, MDF boards use some type of urea formaldehyde resin. On the other hand, Pateco's molded door skin is made with phenolic formaldehyde resin. Pateco's (Masonite) molded door skin is the only known molded door skin with such resin that makes boiling test possible.

b. each partner agency (the UN, World Bank, Asian Development Bank or other qualified international organizations) has its own monitoring and auditing rules which will be applied to their respective projects d. the projects itself will also have rules & regulations outlining their individual strategies to increase transparency and accountability. E.g.
