Definition
A compressible foam sealer is a plastic foam strip that is over-compressed before insertion into a joint to create a seal.
Purpose
The purpose of a compressible foam sealer is to provide a flexible, airtight, and watertight seal in joints and gaps, accommodating movement and expansion while preventing the ingress of air, water, and contaminants.
Examples of Use
- In building construction, compressible foam sealers are used in expansion joints to accommodate movement caused by temperature changes.
- They are used in window and door installations to seal gaps between the frame and the wall.
- Compressible foam sealers are utilized in HVAC systems to seal ductwork joints and prevent air leakage.
Related Terms
- Expansion Joint: A joint that allows for movement between parts of a structure.
- Gasket: A material placed between two surfaces to prevent leakage.
- Caulk: A flexible material used to seal gaps and joints.
Notes
The effectiveness of a compressible foam sealer depends on the material's ability to maintain compression and its resistance to environmental factors such as UV radiation and moisture.
