Trussed Roof Solution

DriSpace offers H1 Systems Solutions to provide sufficient air flow in the roof cavity and an airtight envelope – creating an energy-efficient, breathable and healthy build, while minimising condensation.

Incorporating passive ventilation, high-vapour permeable underlay, vapour control layers and airtight membranes to provide condensation control and air barrier solutions.

DriSpace Systems include CodeMark Certified underlays and wall wrap, BRANZ-appraised VENT products and AS/NZS Compliant ProctorPassive membranes.

System components

G1200N/G2500N - over fascia vent
G1200N - Designed to discreetly ensure a positive airflow of 10,000mm2 / LM. For trussed roofs with pitches greater than 15°.

G2500N - Designed to discreetly ensure a positive airflow of 25,000mm2 / LM. For trussed roofs with pitches less than 15° and skillion of any degree pitch.

G502 - insulation guard
Designed to maintain a continuous 25mm air gap between the roof underlay and the insulation. FRU38 or RU24 - roof underlay

RU24 - Non fire-retardent, vapour-permeable, synthetic selfsupport roof underlay. FRU38 - 220gsm fire-retardent, vapour-permeable, synthetic self-support roof underlay.

Optional

VB10 -ventilation & drainage batten
To defer dew point condensation, install VB10 above the underlay.

G1275 - eaves comb filler
Prevents entry of birds and large insects.

Proctorpassive Smartvap
Install SmartVap at wall and ceiling to make a continuous airtight envelope.
