Longevity and efficiency of PEB roofing systems

In this discussion, Ar. Debasish focuses on the function of insulated metal panels, design considerations, and insulation materials in optimising PEB roofing systems.

How can longevity and sustainability be achieved using insulated metal panels for roofing in PEB structures?
Non-corrosive metals, such as aluminium top sheets, can increase the longevity of insulated panels. These panels operate as a thermal insulator, limiting heat exchange between the interior and exterior rooms and lowering the operation expenditure by almost 10 percent for air-conditioned buildings by reducing heat load.

Please elucidate the significance of design detailing in PEB structures.
At TUMAS, we believe “form follows function”. However, provided the function is justified in design, building/superstructure shapes such as cladding patterns can be realised through design detailing.

What are the challenges in installing roofing systems for pre-engineered buildings, and how can these be mitigated?
One of the most significant installation issues is the availability of competent and experienced workers. However, manufacturers supplying PEB structures can alleviate such scarcity by offering training and development programmes for trained and semi-skilled workers.

What are the preferred insulation materials for PEB structures?
Rigid polyurethane foam (PUF) panels are widely preferred due to their high thermal resistance and lightweight properties.

How can insulation materials be tailored to improve the energy performance of pre-engineered buildings?
PUF panels can be modified to provide better insulation by increasing porosity, which improves thermal resistance. Additionally, increasing the thickness of PUF panels improves their insulating capacity, resulting in higher energy efficiency in pre-engineered buildings.
