Our ExpertiseHow OurInsulation Solutions Work

Greenoak Construction offers a wide range of insulation services that can improve your home’s energy efficiency and make it more comfortable to live in.

Attic insulation, external wall insulation, floor insulation, roof insulation and retrofit insulation are all different types of home insulation.


  •  Attic insulation involves adding insulating material to the floor or walls of an attic. This can prevent heat loss through the roof and significantly reduce energy bills.
  • External wall insulation includes adding a layer of insulating material to the exterior walls of a building. This can reduce heat loss through the walls, as well as improve soundproofing and protect against dampness.
  • Floor insulation involves adding insulating materials beneath the floorboards or concrete slab of a building. This can minimise heat loss through the ground and can also reduce noise.

We recently had our home refurbished by Greenoak construction, and the work they did is beyond anything we could have imagined. Pat and Louise’s experience and input was invaluable, taking our original ideas about the reno and expanding upon them so that we’re now in a house we’re thrilled to be living in. I can’t recommend them highly enough! (And on top of that, they stayed on schedule!!)

With Greenoak Construction, we got both a builder and a house designer. Pat and his team transformed a fire damaged house to a repaired and renovated house. The outcome is an upgraded house with an applied practical design, quality build and an energy-efficient house. They delivered an excellent and comprehensive project. After living in the house for 6 months we are delighted with our home.What evident during the project included:• Safety was always a priority and prominent.• Pat’s availability and communication throughout the project was second to none. He researched good solutions and was proactive in advising of alternatives and being inclusive of our demands and wishes.• Doing the job right and have pride in job well done are important to us and Greenoak Construction.
