Good to know

Please store under cover and clear of the ground. Avoid prolonged exposure to the elements, especially direct sunlight and rain
Specialist PPE is not required, although if you are cutting the insulation in an unventilated area, it is recommended to use a suitable dust mask
For the cleanest results, use a long-bladed knife or insulation saw and compress the roll slightly while cutting to help maintain control and accuracy
