Flashing, Sealants and Adhesives
During construction of a home, many sealants and adhesives are
Sealants are used to provide weather tightness, but unfortunately
have a lifespan signficantly less than the building. They are generally
man made - solvent, water based or low VOC.
- Select sealants appropriate for the task in terms of durability
- Sealants must be carefully maintained and replaced at the end
of their lifespan.
- Use water based sealants, low in VOCs.
Flashings and Seals
External trims and flashings, applied correctly add significantly
to the durability of a building. Omitting or incorrectly installing
flashings generally leads to leaky buildings.
Wind seals and weather seals also signficantly reduce building
heat losses. Using the appropriate seals around doors and window
frames reduces the escape of warm air from the building or entrance
of cold air.
Adhesives and Glues
Adhesives and glues are a common source of internal air pollution.
They must be used stricly according to correct safety procedures,
and with good ventilation.
Poor application practices can present a health risk to both the
builders and inhabitants. This applies particularly to glues used
over large areas such as flooring. The highest level of emmission
occurs during application and immediately afterwards. There should
always be an adequate rest period between use and occupancy.
Always use water based, low- VOC glues in preference to solvent
Using glues and strong adhesive tapes often frustrates attempts
at salvage or recycling on demolition. Mechanical fixings are generally
the environmentally preferable option.
New innovative tape systems [velcro tape] can be used for wall
panels to allow panels to be removed and replaced with ease. This
is a consideration when families are expected to downsize in short
