How to cut Gramitherm® insulation boards easily and efficiently with the GramiCut
Gramitherm® boards, made from natural grass fibres, require a clean cut to ensure optimum installation. The GramiCut, specially designed for this material, makes the task much simpler while ensuring a professional result. It's ideal for small and medium-sized jobs. For larger jobs, we recommend using an Alligator saw (e.g.: Dewalt DCS397N), which is better suited to large volumes and repeated cuts.
Why choose the GramiCut?
The GramiCut has been developed to meet the specific requirements of the natural fibres in our panels. Unlike conventional cutting tools, it allows:
- A clean, precise cut, without fraying the fibres.
- Saves time thanks to its ergonomic design and easy handling.
- A safe experience, with an adapted blade that minimises risks.
Steps to efficient cutting:
Prepare the workspace
Set up your panel on a stable, flat surface to ensure a straight cut. Make sure the area is well lit and clear.
Mark the cutting lines
Use a ruler and a permanent marker to mark the cutting lines directly on the panel.
Use the GramiCut
Guide the saw along the marked line, exerting even pressure. The blade glides easily through the fibres.
Finishing the cut
Check the accuracy of the cut and make adjustments if necessary.
A few tips for optimum results
- Be sure to maintain even pressure on the saw to avoid damaging the panel.
- Clean and sharpen the blade regularly with the Gramitherm® sharpener to maintain its efficiency.
- For projects requiring complex shapes, carry out tests on off-cuts of panels.
How to install Gramitherm® insulation boards efficiently
Gramitherm® insulation boards, made from natural grass fibres, offer thermal performance and acoustic comfort in an environmentally friendly way. To take full advantage of their benefits, it's essential to follow good installation practices. Discover our tips for easy, quick and effective installation.
Why choose Gramitherm®?
Gramitherm® panels are not only environmentally friendly, they're also very versatile. They can be used for a wide range of applications: partitions and walls, floors and ceilings, attics and roofs, external or acoustic insulation. Their lightness and flexibility make them an ideal choice for quick and easy installation.
Steps for successful installation
Preparing the substrate
Make sure the surface where you are going to lay the panels is clean, dry and level. Repair any unevenness and remove any moisture before you start.
Cut the panels
Using the GramiCut, cut the panels to the precise dimensions of the area to be insulated to avoid thermal bridges.
Position the panels
Lay the panels carefully: insert them well between the studs for even insulation. Make sure the panels fit snugly, with no gaps between them. Start at the bottom for the walls.
Finish with a facing
If necessary, add a vapour barrier and cover with a facing (plasterboard, panelling, etc.) to protect the insulation, while complying with local standards to ensure the safety and durability of the work.
Practical advice
Handling
Gramitherm® panels are lightweight and do not require gloves. However, it is strongly recommended to wear glasses when installing horizontally.
Panel joints
Ensure that the panels fit tightly, with no gaps between them.
Storage before installation
Store panels in a dry place, away from moisture, until they are installed.
The importance of membranes in Gramitherm® insulation systems
Membranes play a key role in the efficiency of an insulation system. They complement the performance of Gramitherm® panels by ensuring airtightness and water vapour management. This combination optimises thermal comfort and extends the life of the materials. To guarantee quality, Gramitherm® works with Ampack, a recognised expert in professional membranes.
The benefits of membranes
Airtightness
Reduces heat loss by blocking infiltration.
Vapour management
Prevention of condensation and mould in walls.
Durable protection
Shields against moisture, wind and dust.
Gramitherm® and Ampack: a strategic collaboration
Thanks to this partnership, we can offer membranes that are perfectly adapted to Gramitherm® panels. Ampack supplies high-performance vapour barriers, rainscreens and waterproofing strips, guaranteeing optimum synergy and tailor-made technical support.
Tips for efficient installation
- Select the right membrane for the application (wall, roof, floor).
- Carefully fix the membranes to avoid wrinkles and tears.
- Seal the joints with compatible strips to ensure a perfect seal.
