NoMR! - Improved Wildfire Preparedness through Cross-Sectoral Dialogue

The project aims to form a holistic description of vulnerability that is quantifiable and transferable from spatial and temporal variables. Using this as a basis, the distribution of responsibility and roles of actors can be descr…
Project

Fire Safe Implementation of Mass Timber In Tall Buildings

Research of the fire performance of CLT and Glued Laminated Timber buildings, with visible wood surfaces.
Project

European approach to assess the fire performance of facades

The project is formed in accordance with the Invitation to Tender for “Finalisation of the European approach to assess the fire performance of facades” (Call for tenders No 761/PP/GRO/IMA/19/1133/11140) of the European commission …
Project

Up-scaling of lightweight multi-functional concrete and ceramic materials

Development, characterization and upscaling of lightweight materials and components. Introducing new functionalities like self-sensing, easy-to-clean, photocatalytic materials due to the addition of the nanoparticles. Accelerating…

Thermal Conductivity Measurement Using Slug Calorimeter

Do you want to characterize a material regarding its thermal conductivity or thermal transport parameters at high temperatures? We can measure effective thermal conductivity up to 1 100 °C
Service

Thermal Conductivity Measurement using THW-method

Different fluids and pastes have different thermal conductivities at different temperatures. We perform thermal conductivity measurement on different fluids as well as oils, coolants, colloidal suspensions, aerogels, etc

Thermogravimetric Analysis and Differential Scanning Calorimetry

By simultaneous assessment of calorimetric (energy flows) and gravimetric (mass changes) measurements we can characterize the response of a material when heated or exposed to different gases.  With our 'Simultaneous Thermal A…
Service

Thermal expansion

To ensure that a choice of material is correct throughout the temperature range of the product, it can be important to know the thermal expansion. With our equipment we can measure the thermal expansion and calculate the coefficie…
Service

Thermal Conductivity Measurements TPS method

We measure thermal conductivity (i.e. heat conduction) using the Transient Plane Source (TPS) method according to ISO 22997-2 for which we are an accredited laboratory. The TPS method can be used to measure the thermal conductivit…

Thermal Properties

Do you want to characterize your material regarding its thermal conductivity, insulation capacity, latent heats of reactions or its stability at high temperatures?
Expertise

Wildfires

In Sweden the rescue services responds toon average 5000 annual incidents of wildfires. Most of these are small and during the last 200 years the annual burnt area have decreased by about 99 %. However, societal and climatic trend…

Fire Safety of timber buildings

RISE is a global leader of research of fire safety of timber buildings, developing fire resistance calculation methods and performance based design methods.
Expertise

Multiphysics

Many problems in modern science or engineering are of multiphysics character. This means that they are governed by more than one type of physics, each normally represented by a set of partial differential equations. At RISE we can…
