Icynene® LD-C-50® or MD-C-200™ spray foam can be used to insulate interior walls for thermal insulation, air quality, moisture management, or noise reduction.
Common Problems with Internal Wall Insulation
Other insulation types commonly used internally, such as fibreglass, can have the following issues:
- Unwanted noises are heard originating from plumbing runs or from the adjoining space.
- Pollutants passing through gaps in the wall and insulation.
- Moisture traveling through walls, which can cause condensation and mould.
- Insulation sags over time and there may be gaps around penetrations and joints, reducing thermal insulation against designed values.
Reasons for Insulating Interior Walls Using Icynene
Internal walls may be insulated using Icynene spray foam insulation for the following reasons:
Icynene light density spray foam insulation, and to some extent Icynene medium density spray foam, can reduce airborne and flanking noise.
- Wall between occupied space and noisy space such as industrial plant, parking garage, concert hall, swimming pool, or classroom.
- Wall between occupied space and space with occasional flanking noise, such as toilet flushing or kitchen sink tap running.
- Wall between two occupied spaces or between an occupied and an unoccupied space to maximize privacy and/or maintain a quiet working environment – such a board rooms, offices, quiet media rooms, operating rooms, or hotel rooms.
Icynene spray foam insulation can be used to avoid energy loss from conditioned spaces.
- Wall between a conditioned space (heated or cooled) and an unconditioned space, e.g. plant room, parking garage, storage room.
Air Quality Control
Icynene spray foam insulation acts as an air barrier and can protect against ingress of pollutants such as dust and dirt, mould and moisture, carbon monoxide, and pollen – to improve indoor air quality (IAQ).
- Wall between occupied space and space with pollution, such as plant room, boiler room, chemical storage area, parking garage.
Icynene spray foam insulation acts as an air and moisture barrier and can protect against mass transfer of moisture, also protecting against the resulting condensation and mould issues.
- Walls between regular rooms and rooms with high moisture, such as swimming pools and rooms with water tanks.
- Walls between conditioned and unconditioned rooms in hot/humid climates.
- Walls between regular rooms and highly conditioned rooms that need to minimize moisture ingress, such as controlled environments for manufacturing computer chips.
