Custom Entrance Doors have recently become almost a trend in many cities. There are 100's of designs, styles, colors, types of wood available. Most of these doors are being imported from Oshawa.
Lots of wood in Oshawa air dry and you will find very few kilns in this area. The result is that the timber was not dry and there is a chance of failure in these doors. Namely, there may be too much moisture in the wood and increase the possibility for the door to warp. If you are looking for entry doors in Oshawa then you are at the right place.
Most of the doors are made in North America to use kiln-dried wood. Many North American Door Manufacturers use engineered wood substrates as the core of the interior. Engineered wood is supposed to reduce the amount of motion in the door.
Many custom entrance only 1/8 "or 1/4" solid wood veneers on the exterior and interior of the core is engineered wood. Although there are some companies still exist that the US built the exit of "Solid Wood". I believe the best quality door still Doors Solid Wood. You do not have to worry about getting stripped screw or delaminating of the veneer.
The most popular type of wood for the entrance includes Mahogany, Oak, Alder, Maple, and Walnut. I would recommend a wooden door because it will tend to scratch or damage. Also, important is the finish. Be sure to use with UV protective clear coat.
Many contractors use the Spar Varnish but there are better products out there. I prefer Exterior Finish made in Italy called ICA. There is also another high-end finishes the so-called "West System".
