ABSTRACT
The insulation performance of building envelopes is one of the areas with a significant impact on
the building energy intensity. In Poland, 71 % of the energy demand of the entire building is used
for heating households. Therefore, solutions are sought that will ensure the required thermal
comfort and reduce the energy demand. The paper presents the testing of the temper- ature
distribution inside an envelope made of structural insulated panels (SIPs) using state-
-of-the art FBG sensors. Compared to classic temperature measuring devices, FBG sensors are
characterized by high measuring resolution and reliability, reducing the testing invasiveness to
the minimum. A composite structural insulated panel (SIP) and a traditional two-layer wall were
tested. SIPs are modern building materials that are both a structural and an insulating element of
building envelopes. The three-layer structure consists of a light core (EPS) skinned on both sides
with magnesite boards which provide the panel with high strength, rigidity, fire resistance and
resistance to biological corrosion. The knowledge of the actual temperature distribution inside the
envelope can significantly improve the control of heating systems in
buildings and reduce energy consumption.
