 RETROSEAL: Domestic, Rural & Flameguard
RETROSEAL DOMESTIC
A PVC weather and vermin proof flashing that can be installed on new and existing buildings, domestic sheds, garages and homes with a concrete floor that eliminates corrosion from wall sheet contact with concrete.
RETROSEAL RURAL
A similar use to Retroseal Domestic except that it is heavy duty steel based with a PVC coating where it comes in contact with the concrete, and is designed especially for extreme rural application on new and existing buildings.
RETROSEAL FLAMEGUARD
An all steel, zincalume coated flashing that fits under the overhanging roof sheet and behind the gutter that acts as a vermin and bird barrier under the roof sheet where the profiles are open. Also controls gutter overflow into the building in storms or where the gutter is blocked. Most importantly as a shield to help prevent burning embers entering the building through the open profiles when leaves and debris in the gutter catch fire during the fire season.
This product can also be used at floor level where corrosion is not considered to be of concern particularly in the dry inland rural areas.
Presently available in Stramit Monoclad, Bluescope Trimdek Hi-Ten and corrugated profiles. Other profiles to follow.

RETROSEAL FLAMEGUARD
- Helps prevent embers and flames entering the building due to the build up of debris and leaves in gutters in fire season.
- Also helps provide fire protection to open profiles of wall sheets at slab level.
- Prevents water overflowing back of gutter into building in a storm or where gutters are partially full with leaves and debris.
- Prevents birds and vermin entering into building through open profiles of roof sheet.
- Made from zincalume coated steel.
HOW RETROSEAL WORKS
 The major problem with fitted flashing is the shrink and creep of the sheet profile due to either deliberate shrinking or expanding of the sheet by installers to conform to an ideal finish position, realigning of the sheet to run parallel with the building or to finish sheeting in an ideal position in regard to the flashings, caps or the building length or the slight variation in manufacturers roll-mills. (roof sheeting is really easy to shrink and very hard to expand therefore shrink is the area needing the most attention).
These products address these problems in several ways:
Firstly...
The product is made in sheet widths so creep or shrink doesn't progressively get out. In shrink by cutting a little off the length with tin snips allows to some degree to maintain sequence. Even cutting it in half and cutting a little of both pieces helps with this.
Secondly...
The profiled area is set at 120 degrees from the main body of the flash and its unique shape and length of profile is thus, that it sits at an angle greater than 120 degrees creating pressure on the joint. So where the sheet is in shrink (the profile on the sheet deeper) it flexes into it, or, on creep (the profiles on the sheet shallower) it flexes back. In an extreme circumstance where an odd sheet may be well out of shape, some trimming of the profiles may be necessary.
Thirdly...
Metal versions only - the male profile can be tapped with a hammer deeper into the female underside or inside of the sheet. Decreasing the angle of the flashing having the effect of increasing the reach of the profile tongue into the sheet. (see drawing) |
