How is Jet Stream Max and Supafil Carbon Plus Retrofitted?
Home Roasting in Summer or Freezing in Winter. We have a solution.
Getting insulation into existing walls isn’t as tricky as it sounds. It makes an enormous difference to the thermal and acoustic performance of the home making it more comfortable all year round.
With the right products and machinery, existing brick veneer and double brick walls can be insulated without having to tear the wall apart.
There are two ways that an existing wall can have cavity wall insulation installed and most homes need a combination of both techniques. The first installation technique involves pumping insulation from up on the roof, down into the wall cavity by lifting up the roof tiles that sit directly above the wall.
Where a cavity is blocked from above and also under windows, insulation is installed by drilling and filling. To drill and fill, small holes are drilled into the mortar joint of the brickwork and a nozzle is placed into the wall to blow in the insulation. Once the cavity is filled, the holes are patched with mortar to match as closely as possible to the existing.
Please be aware that every home may not have had wiring checked or upgraded over the years and past owners so what specific condition it may be in is the responsibility of the homeowner to research.
Please understand whether electrical wiring encapsulated in walls or totally covered over on a ceiling space. Though our products are a Group 1 Insulation (Non-Combustible), to comply with Codes it is advised you have a Licenced electrician inspect your wiring prior to install.
Any person installing insulation must engage an electrician to ensure that the electrical wiring and components are safe to be surrounded by insulation.
Electrical inspections are required for ALL insulation installs regardless of the insulation type or install location. DO NOT engage a contractor who will not conduct an electrical inspection or provide a certificate of electrical safety.
There are different levels of power allowed through your electrical cables depending on the type of insulation that surrounds them. The reason for this is a cable that is completely surrounded by insulation can’t dissipate as much heat as a cable with insulation only touching one side. If you have too much power running through a circuit that is surrounded by insulation you run the risk of overheating and fire.
In most cases, when any loose insulation is present in the ceiling and/or walls, cables are deemed as completely surrounded by insulation. Recent changes to AS3008:2009 (The Australian Standard for Electrical Wiring) have reduced the amount of power allowed to run through older wiring when completely surrounded by insulation.
For example, a standard 2.5mm V75 power circuit is allowed up to 20 Amps if there are just batts in the home but only 13 Amps if there is any loose insulation.
Reducing a circuit to only 13 Amps can cause nuisance tripping in high load areas. For example, when your jug and toaster turn on in the kitchen simultaneously, a 13 Amp circuit will most likely trip. In most houses, this can be easily fixed by running a new circuit to high load areas such as kitchens and wet areas. If running additional circuits isn’t feasible, alternative solutions must be sought.
Though the Jet Stream max is non-combustible. By law there needs to be compliant downlight covers or ICF fire rated LED lights that may be covered over by insulation.
