Why Balsa
Balsa is the industry standard for breakaway wood because it does two contradictory things: it looks and finishes like real lumber, and it fractures cleanly with a fraction of the force. A performer can put a fist, a shoulder or a chair through it and walk away. SPFX Supply is the largest balsa supplier in Canada, with all four thicknesses in stock in Toronto in full 96 by 48 sheets.
Pick the Thickness by the Gag
1/4 Inch: Thin Panels and Fast Breaks
The lightest sheet. It breaks with almost no resistance, which makes it right for window mullions, picture frames, shelving, cabinet doors, lightweight panel inserts and any high-speed stunt where the performer must go through with minimal contact.
Price: $365 per sheet. 1/4 inch balsa
1/2 Inch: The Default
The most popular thickness. It is substantial enough to read as real wood, drywall or paneling on camera and still breaks with far less force than the thicker sheets. Wall panels, tabletops, chair seats, crate sides, interior door panels. If you are not sure, start here.
Price: $660 per sheet. 1/2 inch balsa
3/4 Inch: Doors and Furniture
Mid-weight. Thick enough for full doors, wall sections and furniture that has to survive being handled and sat on before the take, lighter than 1 inch for faster breakaway action and easier rigging.
Price: $805 per sheet. 3/4 inch balsa
1 Inch: Heavy Duty
The heaviest sheet. Exterior doors, structural-looking wall sections, large furniture, anything that needs to hold a hinge, take a latch, or look like a 2 by 4 when a performer comes through it.
Price: $920 per sheet. 1 inch balsa
Building With Balsa
Cut it with standard woodworking tools; a fine-tooth blade gives a cleaner edge. Glue joints with wood glue and brad nails rather than screws, which split it. Where a piece must hold weight before it breaks, back it with a thin breakaway rail and score the break line on the hidden side so the fracture goes where you planned. Keep the real structure (the frame, the hinges) on a separate piece so the balsa is only the part that fails.
Finishing
Balsa takes paint, stain, wood grain and veneer. Prime it first because it is thirsty. Match the finish to the surrounding set so the breakaway element disappears until the moment it breaks. Scenic departments routinely finish balsa doors next to real doors and nobody can tell on camera.
How Much to Order
One piece per planned take plus two spares. A door uses most of a 3/4 or 1 inch sheet; a tabletop or wall panel comes out of half a 1/2 inch sheet. Sheets do not come back, so build the count into the schedule. We hold stock of all four thicknesses, so a same-week top-up from Toronto is normal.
Frequently Asked Questions
What thickness of balsa should I use for a breakaway door?
3/4 inch or 1 inch. Doors need to look solid in the frame and survive handling until the take, and the thicker sheets hold a hinge. Half inch works for interior panels on a door that is only ever kicked once.
What size are the balsa sheets?
Every sheet is 96 inches by 48 inches, the same footprint as a sheet of plywood, in 1/4, 1/2, 3/4 and 1 inch thickness.
How much do balsa wood sheets cost?
1/4 inch $365, 1/2 inch $660, 3/4 inch $805, 1 inch $920 per 96 by 48 sheet. All four are in stock in Toronto.
Can balsa be painted and finished like real wood?
Yes. It takes paint, stain, wood grain finishes and veneer. Scenic departments routinely finish balsa to match the surrounding set so the breakaway piece is invisible until it breaks.
Can balsa be reused?
No. It fractures on impact and cannot be rebuilt. Order one piece per take plus safety stock. Half inch is the most popular thickness partly because the cost per take is lowest for a convincing break.
