What do you test?
We are a full-services optical & thermal testing laboratory, with a broad scope in material optical & thermal property testing. Thanks to the strong demand from the building & construction industry, we test the optical and thermal properties of facade & roof materials primarily.
Below is the list of our four most popular testing services:
- Facade & roof material daylight reflectance (SAC-SINGLAS accredited)
- Glazing system solar/luminous/thermal properties (SAC-SINGLAS accredited)
- Roof material solar reflectance index (SRI, SAC-SINGLAS accredited)
- Insulation material thermal conductivity (SAC-SINGLAS accredited)
We also provide a long list of specialized and advanced optical & thermal testing services. Please refer to our full list of testing service.
On the other hand, we want to stay focused. We do not provide testing services not related to optical & thermal properties.
