My wonderful interior design client in Fort Langley, wondered if we should use Plywood, MDF or Melamine boxes for her kitchen cabinets. She had heard Plywood was stronger than Melamine or MDF. Is it? Here's the inside scoop with help from my fabulous cabinet supplier Shari from Century Cabinets:
Plywood: Plywood boxes have a finish on them, but if oil or food spills, it will get into the finish; causing rings and we can't refinish them. Therefore, if you want to use plywood, it is best to use a shelf liner to protect the finish. Wood will take on odors that melamine will not.
Any cabinet that is wider than 36" should not be used for heavy dishes as the shelves may sag over time, this applies to plywood as well as melamine. Plywood is lighter than both MDF and melamine, and the installers like it, however, plywood has more of a tendency to warp. Plywood may last a bit longer than melamine if it gets wet, but not much. It will rot if it is constantly wet. Plywood is an upcharge as well, because good quality cabinet makers don't use Chinese plywood.
Melamine: Melamine is more economical and easier to look after for the kitchen and bathroom cabinet boxes and shelves. Melamine cabinets are made of a good quality fiberboard with a hard melamine surface that is waterproof and therefore will clean up with soap and water, and stains can be cleaned with Clorox wipes. They are the most durable surface and don't require shelf paper. They also do not tend to hold odors from foods or spices, and they are the most cost effective choice.
MDF: (Medium Density Fiberboard). MDF is a dense fiberboard and very heavy, in fact, too heavy for cabinet boxes. MDF doors cost as much as Maple framed doors and they are heavier than Maple doors. Cabinets are not made of MDF because of its heavy weight. Most slab doors are made of MDF and have some veneer or laminate on the surface. Shaker MDF is a choice that allows for the shape of the shaker door without joints which crack when painted on a wood frame door.
The most expensive dining room table from Italy will often be made of MDF and have a beautiful veneer applied to it. MDF is very dense and it is what a slab door is made of with a veneer applied to it. MDF does not warp like solid wood does. This allows the table to open cleanly without sticking.
Many people have been convinced that wood is the only material to build from. This is just marketing hype. Wood has many great qualities but it also has downsides. It is worth learning about materials as they all have good sides for certain applications and they all have downsides too. Think of how old antique cabinets have squeaky doors and drawers that stick. That is because wood warps. :)
Hope this helps you make the decision between Plywood, MDF and Melamine kitchen and bathroom cabinet boxes and doors.

Recessed lighting spacing for interior design - How many recessed lights do I need? How far apart do I place my lights?
Good lighting placement is key for any space, especially so for recessed lighting - (we call them pot lights in Canada - no not those sort of lights!). I've written this handy post to show you how it's done!
(We'll talk about bathroom lighting in another post!).
Recessed lighting layout:
Part A: How many pot lights do I need?
Formula: total sq. footage x 1.5 = total wattage needed. Total wattage divided by 60 watts (or whichever wattage you need) = total amount of recessed can lights.
Example: 240 square foot room x 1.5 = 360 divided by 60 (the bulb wattage I'd like to use) = 6 recessed lights needed.
Part B: Draw up a ceiling diagram (reflected ceiling plan) showing the amount of lights you need (Part A formula). The cans / pot / recessed lights should be evenly distributed around the room, usually they are in rows with an equal number of cans in each row. Here's a great example, the red dots show the recessed lights, the purple dots show the under cabinet lights:
Now we will calculate the spacing between each light.
Part C: Light spacing in a row:
Part D: task Lighting Layout:
Task lighting is extra lighting used to highlight spaces where you need either extra light, or specialized lighting.
You may want to add under cabinet lighting, or pendant lights over the island to bring the lighting closer to the work area.
How to calculate the distance and spacing for task lighting:
Step 1: Determine the distance from the ceiling down to the surface you wish to light, ie. the floor or a countertop.
Step 2: Divide this distance by 4 to obtain the distance from the wall to the first light unit. Ie. 8' ceiling lights should be placed two feet away from the wall.
Part E: Wall washers recessed lighting layout: (lighting that shines down onto a wall in order to highlight art or a wall feature)
Step 1: The rule for installing wall wash recessed fixtures is approx. 1.5' to 3' away from the wall.
Step 2: Fixed lights can be placed closer to the wall.
Step 3: Place adjustable lights farther away from the wall. The optimal aiming angle to minimize glare is 30-degrees from the ceiling, that way we avoid glare.
Step 4: Space wall wash fixtures the same distance from each other.
Step 5: A good rule of thumb is that your accent lighting should be 3 times brighter than the ambient light in the room.
Part F: Beam Spread
There are generally 2 types of recessed lights - Spot lights and Flood lights.
Spot lights have a narrow beam of light casting light to a focussed area, usually these are used to highlighting art or important design elements in the room. They cast beams 45 degrees or less.
Flood lights case a wider beam on the floor area and are used for lighting larger, more general areas. They cast beams up to 120 degrees.
Lighting Beam calculation: Angle of beam x 0.18 x ceiling height = Beam spread
Example: 60 degrees x 0.18 x 10' ceiling height = 10'8" wide beam spread.
To create overlapping beams of light for ambience, make sure that your beam spread diameter is equal to or greater than the distance between light sources fixtures.
Recessed lighting installation:
Now that the recessed lighting placement locations are determined, we need to find out if they can be installed in these locations. Use a stud finder to determine where the ceiling joist are located. You might have to adjust placement locations to avoid hitting a ceiling joist. It's always best to pre plan the lighting design before your renovation or new build.
Please remember to contact your electrician before making any electrical decisions.
