Frequently asked questions about the Thermal insulation / construction wool category

What is Thermal insulation / construction wool — what is it used for?

Thermal insulation / construction wool is insulation made from glass wool or stone wool in rolls and boards for insulating walls, roofs, floors and facades. The range includes glass wool (KVL, KNAUF, ISOVER) and stone wool (ROCKMIN, PAROC) in typical sizes 565–610×1000–1250 mm and various thicknesses for thermal and acoustic insulation.

What is the difference between glass wool and stone wool in the range?

Glass wool (KVL, KNAUF, ISOVER) is lighter, flexible for cavity filling and provides good thermal/acoustic insulation; stone wool (ROCKMIN, PAROC) is denser, more fire-resistant and suited for facades and high-temperature applications. Sizes: stone wool commonly 610×1000–1200 mm, glass wool available as rolls and boards like 565×1250 or 1200×1200 mm.

What are the sizes and coverage of PAROC and ROCKMIN stone wool boards in the catalogue?

PAROC LINIO boards are typically 50×600×1200 mm and ROCKMIN PLUS boards 66×610×1000 mm; one PAROC board covers 0.72 m² (600×1200) and one ROCKMIN PLUS board covers 0.732 m² (610×1000).

What sizes do KNAUF and ISOVER glass wool products come in and how to calculate coverage?

KNAUF EXPERT 036 is offered in boards such as 50×565×1250 mm (package area e.g. 11.3 m²) and 150×565×1250 mm (3.53 m²); ISOVER STANDARD 35 is 150×565×870 mm (3.44 m²). Calculate coverage by multiplying width×length in metres (0.565×1.25 = 0.70625 m² per board).

Is ISOVER VARIO XTRA KILE 1.5M×40M suitable for loft vapour control?

Yes, ISOVER VARIO XTRA KILE 1.5M×40M is a 1.5 m × 40 m roll designed for vapour control in lofts, managing moisture transfer. It is compatible with ISOVER insulation boards when installed correctly to ensure proper diffusion control.

Which tape to use for insulation joints — is ISOVER FACADE TEIP 90MM suitable?

ISOVER FACADE TEIP 90MM is a 90 mm façade tape suitable for sealing joints of stone and glass wool boards and connections of vapour/wind barrier membranes. It’s appropriate for external seams and interfaces, especially within ISOVER systems.

Can I use glass wool for soundproofing between rooms?

Yes, glass wool products like KNAUF ULTRA ACOUSTIC are designed for acoustic insulation and work well as cavity fill in partition walls to absorb sound. Choose acoustic-specific boards with adequate thickness (for example 75 mm) and sizes such as 75×610×1250 mm.

Which insulation is better for façades — PAROC LINIO or ISOVER?

For façades, stone wool like PAROC LINIO (50×600×1200 mm boards) is commonly preferred due to higher density and fire resistance. ISOVER glass wool is better suited to internal and framed structures where flexibility and lighter weight are advantages.

What is PUISTEVILL ISOVER VV-041H INSULSAFE and where to use it?

PUISTEVILL ISOVER VV-041H INSULSAFE is a loose‑fill blown glass wool insulation used to fill irregular cavities, lofts and between joists. It’s suitable for uneven volumes and provides thermal and acoustic insulation when blown into place.

How to convert pack m² into number of boards for installation?

Use the pack’s stated coverage (e.g. KNAUF EXPERT 036 packs 3.53 m² or 11.3 m²). Divide the total required area by the area per pack and add about 5–10% for cutting and waste. Alternatively calculate area per board by multiplying width×length in metres.

Can I combine ISOVER VARIO XTRA roll with PAROC stone wool boards?

Yes — ISOVER VARIO XTRA vapour control membrane can be used with PAROC stone wool boards provided vapour control and wind barrier layers are correctly installed. Typical build-ups use denser PAROC externally and ISOVER vapour control internally.
