Insul-Baffle

• Insul-Baffle separator - 2 pack box
• 45mm x 650mm x 6Lm

Preserves an air gap. Typically used to ensure roof insulation is separated from bulk insulation where the roof underlay and insulation may be pressed together near the eaves.

Contributes to air flow. When used as part of a passive roof space ventilation design.

Suitable to be used in long run or metal tile clad truss framed pitched roofs, either timber or light steel framed.  It may be used in new roof or re-roof installations with either trusses or rafters.

Not suitable for use in Skillion roofs, these require different design solutions.

Key Benefits:

Masons Insul-Baffle is designed to separate roof underlay from bulk insulation where these elements may come into contact, or the required 25mm gap between them cannot be maintained. It assists in meeting the requirements of NZS 4246:2016.6.2.10. 

It also allows a path for air movement as part of a passive–stack ventilated roof space design. Masons Insul-Baffle incorporates ‘Dragon Channels’ to increase rigidity and aid air to cross flow. 

Open Area:

A minimum 25mm air gap between insulation and the roof underlay is required, this equates to an open area of 25,000m㎡ per Lm.  Masons Insul-Baffle exhibits an open area of circa 32,000m㎡ per Lm.  Allowing for possible variations during installation, reducing open area due to bulk insulation intrusion, truss chord blocking air channel, or deformation of crenelations an open area of 25,600m㎡ is realistic.

Clear plastic is recyclable. Masons recommend contacting the local council or waste stream recycling providers in your locality for advice on who can accept clean, dry, fixing free Masons Insul-Baffle for recycling.

Store in cool dry conditions in original cardboard boxes until installation.

15 years, installed per instructions, durability is expected to be for the life of the roof cladding or roof underlay.
