Maxidall Ultra: high-performance insulation, low thickness

A versatile and effective solution

Designed to combine low thickness, mechanical resistance and thermal performance, Maxidall Ultra panels adapt to numerous configurations:

• Under earthwork slab (DTU 13.3)
• Under screed, in direct installation with glued or sealed coverings
• Low temperature underfloor heating/cooling

With a thermal conductivity λ = 31 mW/m·K, Maxidall Ultra achieves:

• R = 4,00 m²·K/W for 123 mm under slab
• R = 8,15 m²·K/W for 250 mm under screed

Made in France from recycled and recyclable materials, these panels combine performance and environmental responsibility.

An optimal compromise between technique and budget

Thanks to their high mechanical resistance, the panels allow for limiting the thickness of the structure without sacrificing performance, meeting the most common thermal requirements.

• Up to 250 mm thickness under screed
• Up to 200 mm under underfloor heating
• Can be laid in two layers (up to 120 mm)

ACERMI certified, Maxidall Ultra is an economical alternative on the insulation market, without compromising on quality.

Integrated acoustic insulation & optimized construction sites

Maxidall Ultra provides effective sound insulation, which can eliminate the need for acoustic underlay.

Available in large formats (up to 2.500 x 1.200 mm), it allows for rapid installation, reducing construction time and costs.

Maxidall Ultra is the combination of performance, economy and durability, designed for construction professionals.
