Blockboard Properties
The technical specifications behind blockboard — sizes, thicknesses, strength characteristics and emission ratings — explained by Ahmedabad's plywood dealer since 1980.
The Technical Side of Blockboard
Beyond the general advantages covered in our advantages of blockboard guide, it helps to know the actual technical specifications — the sizes it's sold in, the thickness range available, and the strength characteristics that come from its solid-strip core construction. This is the reference page for those specifics.
Standard Sizes and Thickness Range
Blockboard is sold in the same standard formats furniture makers already work with.
| Specification | Standard Range |
|---|---|
| Sheet Sizes | 8x4 ft (standard), 7x4 ft, 6x3 ft |
| Thickness Options | 6mm, 9mm, 12mm, 16mm, 19mm, 25mm |
| Recommended for Wardrobes | 16–19mm |
| Recommended for Doors & Partitions | 25mm |
| Core Material | Solid softwood or hardwood strips, edge-glued |
| Typical Lifespan | 15–25 years with proper maintenance |
What Gives Blockboard Its Strength
Four technical properties that come from the solid-strip core.
Bending Resistance
The solid core gives blockboard good resistance to bending under load, which is why it performs well as a large flat panel — table tops and door shutters in particular.
Flexibility Without Cracking
The strip construction allows a degree of flex under stress without the core cracking, which matters for panels that see repeated movement, like wardrobe shutters.
Strength-to-Weight Ratio
A low-density softwood core gives blockboard a strong structure relative to its actual weight — lighter to handle than an equally strong solid timber panel.
Pest-Resistant Treatment
Quality manufacturers treat the core through a vacuum-pressure impregnation process, protecting against termites and borers before the board reaches the market.
Bonding and Emission Ratings
Blockboard's core strips and face veneers are bonded using phenol-formaldehyde or melamine-formaldehyde resin, applied during the hot-pressing stage of manufacturing — see our blockboard manufacturing process guide for the full production sequence. For anyone concerned about indoor air quality, E0-compliant blockboard is available, using an adhesive formulation with minimal formaldehyde emission — worth considering for bedrooms, children's furniture, and any application with prolonged close contact.
Frequently Asked Questions
What are the standard sizes of blockboard?
Blockboard is commonly available in 8x4 ft, 7x4 ft and 6x3 ft sheet sizes, with 8x4 ft being the standard most widely stocked size, matching plywood's standard sheet format.
What thicknesses does blockboard come in?
Blockboard is typically available in 6mm, 9mm, 12mm, 16mm, 19mm and 25mm thicknesses. 16-19mm is common for wardrobe panels, while 25mm suits doors and partitions carrying more load.
How strong is blockboard compared to solid wood?
Blockboard's solid wood-strip core gives it good bending resistance and flexibility without cracking, comparable in many respects to solid wood but with better dimensional stability across a wide panel and a significantly better strength-to-weight ratio due to its low-density softwood core.
Is blockboard available in low-emission grades?
Yes, E0-compliant blockboard is available, using adhesive with minimal formaldehyde emission — a worthwhile option for bedrooms, children's furniture, or anyone sensitive to indoor air quality.
Is blockboard treated against pests?
Quality blockboard manufacturers apply pest-resistant treatment through a vacuum-pressure impregnation process, protecting the wood-strip core against termites and borers before the board is finished and sold.
