cladding weatherboard

Weatherboard

The quintessential Kiwi cladding

Weatherboard homes are classically kiwi - charming,understated and full of character. However, most weatherboard homes built before 1978 are missing something integral to their construction - wall insulation.Together, let's transform your home into a more energy-efficient warmer, drier, quieter and more comfortable place to live - all year round!
cladding brick & block

Brick & Block

The sturdy cladding that a wolf couldn’t blow through - but a winter chill can.

Solid and striking, "you can’t go wrong" investing in an older brick home. But for all its dependability, there’s something fundamental missing in your older brick home… wall insulation. Insulmax® retrofit wall insulation can transform your brick home into a haven of comfort and quiet.
cladding roughcast

Roughcast

Roughcast, stucco, rendered brick, rendered plaster, rendered concrete…

Whatever you call an older "roughcast" home it is probably missing a key element - wall insulation. Whilst some homeowners undertake the daunting task of removing wall linings to add segment insulation, this is an expensive and obtrusive option and often strips older homes of their character. We have the experience and skills to finish your roughcast cladding so that you won’t even know we’ve been - except for a noticeably warmer, drier home!
cladding interior wall

Interior Wall

Insulation for every space: No room left unreached

If your exterior walls are difficult to access, such as those backing onto a garage, Insulmax® has the perfect solution. We can install insulation via your internal walls, ensuring there's no room we can't reach. This method allows us to insulate even the trickiest parts of your home without compromising on comfort or efficiency, providing warmth wherever it's needed.

Ceiling Insulation

Ceiling Insulation Made Easy for Tight Spaces

Heat loss through the ceiling can account for a significant portion of a home's energy waste, especially in uninsulated skillion ceilings. With limited space between the roof and ceiling, traditional insulation methods are often impractical and costly. Insulmax®’s blown insulation is the ideal solution, efficiently insulating your ceiling without the need for expensive renovations, bringing your home up to modern standards.
aproved & certified

 Insulmax® wall insulation is approved by all councils in New Zealand* and holds CodeMark certification, which is the highest level of product assurance in New Zealand. *Installing any type of insulation in the exterior walls of your home requires an application to council for a building consent or exemption
