First Job Complete With New 147mm Fascia Rainwater System

It was rolled out in the Central North Island and the client’s brief was to provide a stylish, practical panel with straight lines. The new 147mm panel was chosen and our customer’s and supplier comments were very encouraging.

Simon Penn from Jennian Homes in Wanganui comments "My first impressions of the 147 Facia is very good. The heavier gauging provides straighter lines and with the longer lengths I am also pleased to see less joins. The soffit junction detail is better than our previous style which will give me a tighter hold resulting in no soffit rattle in very high wind zones".

Graham McLay from Rainaway Manawatu mentions "The system included easy to follow setup details and hip corners were easy to fit to achieve a high standard finish”.

Dimond coated steel fascia systems are available in 147mm and 185mm high panel, roll formed in 0.55mm BMT zincalume with a prepainted ﬁnish only.

Dimond Fascia 147 and 185 are coated steel fascia systems intended for use as fascia and barge boards to support gutter systems, covering roof truss ends and gable ends around the roof perimeter on timber trussed residential buildings. External gutters are then ﬁxed directly to the fascia to allow collection and discharge of rainwater.
Suitable for use with longrun metal rooﬁng, metal tiles or concrete tiled roofs. Reference should be made to Section 2.1.1.2 Environments, to ensure the correct coated material on the fascia is chosen for the environment.
Dimond do not recommend fascia systems are used in very severe marine or geothermal environments as fascia is not available in plain aluminium, AR8, ARX, stainless steel or copper.
Typically 185 panel is used up the gable ends while 147 panel is used along the front.

Rafter and barge bracket centres should be at 900mm centres maximum in low and medium wind areas.
In high wind areas brackets should be fixed at 600-700mm centres maximum.
In heavy snowfall areas, brackets and snow straps must be fixed at 450mm centres.
Level or sloping sofﬁts up to 22.5º pitch can be used.
The recommended set out heights must be maintained to avoid birds and vermin entering the roof space.
Steel products should not come into contact with concrete and must avoid dissimilar metal contact.

Test information available from Pacific Coilcoaters and BHP NZ Steel, and past history of fascia systems, indicate that provided the product use and maintenance is in line with the guidelines contained in the current literature referenced, Dimond Rainwater Disposal Systems can be expected to meet the performance criteria in Clause E2 of the New Zealand Building Code, for a period of not less than 5 years.
If the need arises to use Dimond Rainwater Disposal Systems outside the limitations and procedures given in this or other referenced literature, or, if any doubt exists on product handling or use, written approval for use must be obtained from Dimond, before the project commences.
For consenting it is important to check the correct pre-painted finish has been selected for the environment. Refer to Section 2.1.1.2 of Manual.
