Typha Insulation Material

Project: Restoration and Development of Management Methods in Lowland Peatlands

Drained peatlands, often used as pasture, emit more greenhouse gases than “wet” peatlands.

• Development of different utilisation options for the restored peatlands for plant cultivation
• Use of the plant material for various purposes: horticultural substrate and construction material
• Development of different insulation materials based on Typha angustifolia (cattail): loose-fill insulation, rigid insulation, and insulation boards
• Development and construction of an experimental production facility by project participants in cooperation with TH OWL
• Construction of a test rig and experimental building for insulation materials by Jade University in Oldenburg in cooperation with TH OWL

Building Regulation Approval:

• Material building law is governed by state law
• Model Building Code (MBO)
• MVV TB
• DIBt (MBO, MVV TB, abZ, abP, aBG)

Non-regulated construction products require a usability verification and a conformity confirmation according to §§ 17–25 MBO:

• General building authority approval (abZ)
• General building authority test certificate (abP)
• Individual case approval (ZiE)

If a construction product is intended to contribute significantly to structural load-bearing, it is considered a construction type.

Non-regulated construction types require an applicability verification and a conformity confirmation according to § 16a MBO:

• General construction type approval (aBG)
• General building authority test certificate (abP)
• Or project-specific construction type approval
