Floor Insulation   

High performance floor insulation from Devana keeps the cold out and the warmth in. We have a number of installation methods to suit your home. We start by providing advice to find the best choice for you. Our customers have saved up to 43% on heating costs as well as feeling warmer and more comfortable in every room.

Retrovive for Suspended
Ground Floors  

We have developed a specialised process of fitting insulation into suspended ground floors. This process by Retrovive involves unique hammocks inserted between floor joists to blow high-performance insulation into. This layer of insulation keeps heat in as well as reducing any draughts. Retrovive enables you to enjoy the most of your home.

Many customers of the Retrovive system have achieved savings of up to 43% on their heating bills including those with period home floorboards. Choosing Retrovive to insulate floors is an investment that makes a home more comfortable as well as providing impressive energy savings.

Most floor insulation installation processes require every floorboard to be pulled up and skirting boards removed. This procedure can be very time-consuming and disruptive. The Retrovive process only requires a few floorboards at up to 8 feet intervals to be lifted. Retrovive is an industry-leading quick and easy process with most projects only requiring a day or two to complete for most rooms.

Our high-performance insulation practically guarantees an immediate benefit You’ll be able to quite literally feel the rewards as you turn down the thermostat.  No longer will cold air constantly be blowing right beneath your feet reducing warmth and sending draughts through the floorboards and skirting boards.

Intermediate Floors
from Above   

To insulate intermediate floors from above, Devana blows Cellulose Fibre directly into floor voids accessed by lifting maybe just one board across the room. This blown insulation process ensures there are no gaps through our air-tight method approach.



Using blown-in insulation for floors is one of the most cost-effective forms of insulation. It is quick, easy and can be applied to many types of floor shapes and sizes. Alternative insulations often require a large quantity of materials in order to fill awkward shapes. This can be wasteful, messy, and time-consuming Devana’s Blown Cellulose Fibre Insulation saves both time and money.

Intermediate Floors
from Below 

Devana is also able to blow Cellulose Fibre Insulation into intermediate floors from below. This process requires discrete holes to be made allowing the insulation to be inserted. When complete, we cover the holes and leave them ready for filler and paint.

We recommend using a high-performing Cellulose Fibre Insulation called Warmcel. This has superior thermal capacity in comparison to other insulation products. Due to its excellent insulating properties, you will feel significantly warmer at home whilst reducing emissions and saving money. Devana is very happy to supply this product and we are accredited installers.
