Underfloor Insulation Options


To help retain heat in winter (or to keep your home cool in the summer), it’s best to consider your underfloor insulation options.

Having underfloor insulation is one of the most cost-effective ways of limiting the movement of heat in your home, keeping you comfortable all year round. Our range of underfloor insulation options mean there’s an unique solution for every home.

Landlords & Property Managers

In New Zealand, the underfloor insulation in rental properties must meet a certain standard. 

Installing underfloor insulation for homes with an accessible sub-floor cavity is a requirement of the Insulation Standard – Healthy Homes Standards 2019.

Your One Stop Shop for Underfloor Insulation

There are two main options for underfloor insulation, and GreenSide Energy Solutions will help you choose the right option for your home:


Bulk insulation

Typically made from polyester, natural wool, rock wool, or expandable polystyrene material, this insulation traps heat inside the house during the winter and blocks heat from entering during the summer. 


Reflective foil insulation

Using either single or doubled-sided fall laminates, bubble wrap, or foam foil-faced wrap, the reflective foil insulation can lower radiant heat gain.
