They can be installed in both walls and suspended ceilings, depending on project requirements.

 

Regulations and Recommendations

In Sweden, the installation of inspection hatches is governed by the Swedish Building Regulations (BBR).
In areas requiring fire or moisture protection, special regulations apply:

– Fire rating: EI30 or EI60 is required at fire compartment boundaries

– Moisture protection: Moisture-resistant construction per Säker Vatten or GVK guidelines

– Accessibility: The hatch must be easily accessible and not blocked by furnishings

 

In both new construction and renovation, it is important to use the correct hatch type and ensure installation follows all applicable regulations and manufacturer guidelines.
