If you are sourcing insulation for a project in Thailand, you have probably used the words batts, rolls or blanket — and you may have noticed suppliers quoting “boards” and “strips” instead. They are the same families of product, described two different ways. This page translates between the two, so you can ask for the right thing the first time.
Batts, rolls, boards, strips — what is the difference?
Insulation is sold by format, and format decides both price and labour cost on site:
- Batts / rolls / blanket — flexible, supplied in rolls or folded lengths, typically 25–100 mm thick and 10–48 kg/m³ for glass wool, 30–60 kg/m³ for rock wool. Used for metal roofs, ceilings, partition walls, HVAC ducts and duct wrap.
- Boards — rigid, 40–120 kg/m³, cut square, used where the insulation is part of the structure: exterior walls, facades, fire-rated partitions.
- Strips (lamella) — narrow cut blocks, fibre oriented across the thickness, for sandwich panel cores where compressive strength matters more than flexibility.
- Pipe sections — pre-moulded half-rounds for chilled water and process pipework.
The coloured batt-style product that contractors in Southeast Asia sometimes refer to as “green batts” is simply a mineral wool or glass wool batt in roll form — the colour comes from the fibre and binder, not from a different material. When you compare quotations, ask for material (rock wool or glass wool), density, thickness and format; that combination, not the colour, determines performance and price.
Which format for which Thai application?
- Cold storage and refrigerated rooms — rigid rock wool boards or sandwich-panel strips, 100–120 kg/m³. Panels are usually built in Thailand and shipped to site, so strip cutting tolerance matters.
- Metal roofing and pre-engineered buildings — rock wool or glass wool blanket with foil facing, 50–100 mm thick; rolls are laid over purlins before the roof sheet goes on.
- HVAC ductwork — foil-faced blanket or duct wrap, 25–50 mm, chosen for condensation control in Bangkok’s humidity.
- Fire-rated partitions — A1 non-combustible rock wool boards, density from 60 kg/m³ upward.
- Acoustic control in factories — denser rock wool (80–100 kg/m³) performs better on airborne noise than the same thickness of light glass wool.
Shipping to Thailand: ports and packing
Most of our Thai shipments discharge at Laem Chabang or are consolidated through Bangkok / Lat Krabang ICD. Insulation moves by volume, not weight, so the single most useful number in any quotation is cubic metres per container: tightly compressed blankets fit far more volume into a 40HQ than rigid boards do. Ask for that number and your landed cost per m³ becomes comparable across suppliers.
What to put in a quotation request
- Application (cold room, roof, duct, wall, panel core, pipe)
- Material and density — e.g. rock wool 100 kg/m³, or glass wool 24 kg/m³
- Thickness in mm and format (board / strip / blanket roll)
- Facing, if any (plain, foil, wire mesh)
- Quantity and destination (Laem Chabang, Bangkok ICD, or your factory)
Five lines are enough for us to quote. If you need Thai-language packing or a specific document set, say so in the same message.
Frequently asked questions
Do you supply the “green batts” sold locally in Thailand?
We supply the technical equivalent: mineral wool (rock wool) and glass wool batts in roll or blanket form, in the density and thickness your specification calls for. Send us the local product code or a photo of the label and the specification you are matching, and we will confirm the closest equivalent.
What density of rock wool is used for cold storage in Thailand?
Cold rooms and refrigerated panels are normally specified at 100–120 kg/m³ for rock wool boards or sandwich-panel strips, so the panel keeps its shape and compressive strength at temperature.
Can I mix formats in one container?
Yes — mixed loads of blankets, boards and pipe sections are common, and we will pack so that the container volume is used efficiently. Volumes under a full container are usually shipped LCL.
How fast can you quote?
