STBoard & STLavida | Tech Data

Comparison Table of STBoard™ with Other Boards

MATERIAL	ADVANTAGES	DISADVANTAGES
STBoard™	All of the below	None of the below
Gypsum Board	Economical Easy of fabrication Joints may be sealed by gypsum compounds High availability	Not fireproof, not waterproof, and not moisture-proof Not bendable and thick (minimum thickness is 9mm) Painting works require several coating and soaks up more paint High sagging risk in ceiling applications due to moisture/temperature fluctuation Low sound insulating property
Cement Fibred Board	Cost more than gypsum board but less than Calcium Silicate Board Fireproof, waterproof, & moisture-proof Flat surface Strong	Heavy, not resilient, fragile, and require rather thick board to prevent breakage Difficult to fabricate and wears tools too much Painting works require several coating and soaks up more paint Contains chlorine & produces toxic fumes under fire Must allow for expansion joint lines, and joint lines are hard to seal Surface condensation problems that erode surface finishing works Heat sink
Calcium Silicate Board	Fireproof, waterproof, and moisture-proof Sound insulator Heat insulator Termite and insect proof Flat surface	Heavy, not resilient, fragile, and require rather thick board to prevent breakage Without fibrous reinforcement, thus poor screw and nail holding power Fabrication and finishing problems similar to Cement Fibred Board
Plywood	Cost less than Calcium Silicate Board Straight forward fabrication, accept screws, nails, sanding, puttying, bending, and gluing easily Lighter than Gypsum board	Require pretreatment like puttying, sanding, sealing Painting works require several coating and soaks up more paint Require termite-proofing Rot, delaminate, deform, when exposed to water or high moisture Availibility, quality, and pricing fluctuate widely
Cement Fiber Board	Suitable for exterior applications Can be ordered in many sizes or custom-made forms	Heavy, not resilient, fragile, and require rather thick board to prevent breakage Fabrication and finishing problems similar to Cement Fibred Board Heat sink
Acoustic Ceiling Board	Relatively lightweight Good heat insulation High sound insulation and acoustic values Resist sagging & thus suitable for ceiling applications Not heat sink	Fine mineral fiber drops away from the Acoustic board Become dirty easily yet cannot be painted or repainted Require costlier moisture resistant grade for high moisture areas Joint-lines cannot be jointed or sealed aesthetically
