Frequently Asked Questions
'Will
the beads settle after a while?'
No,
the beads are held together with glue and form a
solid structure. Click here to see the structure.
'I've read somewhere that you
need ventilation in the cavity. How is this possible
when you fill it.
Polypearl
beads are round and when packed together, air can
still circulate around them. Take a look at ventilation. Polypearl complies
with the Irish Agrement board standards.
'Will water not run through
the cavity along the Polypearl.
Again,
the structure of polypearl means that water will not
penetrate to the cavity. Take a look at Water Drainage. Polypearl complies
with the Irish Agrement board standards.
'What is the u-Value of
Polypearl'
0.30
m/k2 for a standard 100 mm cavity.
'Are Polypearl Irish Agrement
Board approved?'
Yes,
Polypearl meets with Irish Agrement Board Standards
for insulation. In fact, we are the only approved
installers of bonded bead in the Republic of Ireland.
Our certificate number is 00/0111. Click here to request a copy of the
certificate or download it by clickng here.
'How do you know when the
cavity is full?'
The
bead is injected at the top of the cavity under high
pressure. Through gravity and this pressure the bead
naturally flows to the bottom of the cavity and
continues to fill upwards. The beads will continue to
fill any available space. When the cavity is full
pressure builds internally and back pressure
automatically stops the injection gun. (Just like
when you're filling petrol)
'How many holes do you
drill?'
In a
typical bungalow gable end we would drill
approximately 10-12 holes at ceiling level. For
existing dwellings, the holes are filled with cement
mixed carefully with coloured sand to match as
closely as possible to the existing mortar, which
soon becomes indistinguishable from the original. For
new buildings these small holes will be covered
completely covered by plasterwork leaving no trace of
work done.
'At what stage should
Polypearl be installed?'
In a
new house, Polypearl should be installed after doors
and windows are fitted and the roof complete. In
existing houses built pre-1980 with cavity walls, it
should be installed immediately. For more information
see Installation.
