Frequently Asked Questions:

How do I effectively insulate pitched roofs using Recticel Eurothane® GP?

Recticel Eurothane® GP PIR insulation boards are a top choice for professional installers due to their lightweight, easy-to-install nature, and capability for efficient on-site cutting. For insulating pitched roofs, position the boards with their long edges parallel to the rafters, ensuring they are tightly butted together in a brick-bond pattern for optimal thermal efficiency. Support all board joints running from eaves to ridge with rafters, and secure boards temporarily with nails before proceeding to counter battening.

What's the best approach to insulate framed walls with Recticel Eurothane® GP?

When insulating framed walls, fit Recticel Eurothane® GP boards between the wall battens in a snug, brick-bond arrangement. This method ensures maximum insulation coverage and thermal efficiency, making it an excellent choice for enhancing the energy performance of framed walls.

How can I insulate floors using Recticel Eurothane® GP boards?

For floor insulation, lay the Recticel Eurothane® GP boards in a tightly butted brick-bond pattern.
