Green roofs

Solutions

Superior thermal insulation

Thermano features PIR as a thermal insulator. This makes Thermano a perfect thermal insulation layer for green roofs.

Thermano application

Thermano is a perfect thermal insulation system for traditional green roofs, both extensive (with moss, lichens, herbs, and grass) and intensive (shrubbery, small trees and large trees).

Benefits

SUPERIOR INSULATING PERFORMANCE

SUPERIOR INSULATING PERFORMANCE

The lowest thermal conductivity coefficient of all thermal insulation materials (λ = 0.023 (W/mK) means better thermal insulation efficiency. In practical terms, this significantly reduces the energy needed to heat the building, which ensures major financial benefits.
LOWER THICKNESS AND WEIGHT

LOWER THICKNESS AND WEIGHT

The relatively lower profile thickness and small density of panel material reduce the overall roof weight, which can help reduce the load-bearing structure costs by 15 or 20%.
DURABLE

DURABLE

The material for the Thermano panels is the most durable thermal insulating material in the construction industry with a service life comparable to the overall building live cycle time: it may last for generations.
ECOLOGICAL

ECOLOGICAL

The product is safe to the natural environment at the production and disposal stages. The panels are made of a material that is 80% recyclable, and in many ways too.
EASY AND QUICK INSTALLATION

EASY AND QUICK INSTALLATION

Compared to traditional thermal insulation technologies, THERMANO requires less consumables to install, while the installation process is less time-consuming and labour-demanding.
LOW WATER ABSORPTION

LOW WATER ABSORPTION

The maximum absorbability ratio of each panel is 2%, which makes the roof structure extremely impervious to mould and fungal attack even if the roof water barrier fails.

Installation

The panels are quick, easy and clean to install. An added value is the compatibility with various vapour-proof and water-proof barriers.

Thermano on an extensive green roof

Extensive green roofs feature low maintenance vegetation. The plants have low vegetation requirements, and the finished green roof requires little or no watering. The vegetation here includes: mosses, herbs, lichens, stonecrops, and succulents. A Thermano installation for an extensive green roof requires no root barrier.

Thermano on an intensive green roof

Intensive green roofs feature what people call "typical" plants: perennials, shrubs, and sometimes trees. These forms of vegetation require a number of maintenance tasks: watering, fertilization, and typical gardening care. Unlike extensive green roofs, intensive green roofs can be used for recreational activities. A Thermano installation for an intensive green roof requires a root barrier.

Exposure to fire

Unlike other thermal insulating materials exposed to high temperatures (e.g. fire), the Thermano material does not dwindle, it forms a permanent and mechanically durable scorch which isolates the structure form destruction by flames.

Manufacturing technology

The chief material used in the production of the Thermano panels is polyisocyanurate (PIR), secured on both sides with a gas-tight cladding, comprising several polymer layers and aluminium foil.

The structure of PIR, the material for the Thermano panels contains over 90% closed cells, filled with a very low thermal conductivity gas. This structure ensures extremely good strength parameters and an extremely low thermal conductivity coefficient of λ = 0.023 (W/mK).

Other advantages of the material include: low absorbability (<2%), complete resistance to VOC, and significant strength; when exposed to high temperatures, PIR does not dwindle, it forms a permanent and mechanically durable scorch. These superior characteristics have been appreciated by U.S. spacecraft design engineers, who were the first to use isocyanate-modified polyurethane (PIR) as a thermal insulating materials for the STS (Space Transportation System), more commonly known as the space shuttle.

Thermano panel structure

Outer component: gas-tight cladding

The high gas-tightness of the Thermano panels ensures stability of thermal insulating parameters (the ageing lambda) over long periods of time (which is 50 years by standard design), unlike other polyurethane-based materials without the cladding, i.e. spray-applied (in situ) materials.

Inner component: polyisocyanurate (PIR) core

The PIR core is formed by polymerization of its two main components, polyols and isocyanates, with an addition of modifiers. The PIR core is a closed cell structure, which means that the material is an essential barrier to capillary wicking of water (by reducing absorbability) and steam (water vapour) diffusion.

The PIR foam exhibits excellent mechanical performance, durability, low absorbability and other physical and chemical characteristics which mark the material out for application even in the most demanding construction environment types (roofs, floors, flooring, foundations, basement walls, etc.).
