Insulation for the floor is simply insulation, which is placed beneath the floorboards. There are many different floor insulation products available on the market. The purpose of installing insulation for the floor is that it can help prevent heat from escaping through the floor. It is said that up to 1/5th of the heat in a building escapes through the floor. This is why it is important to ensure that a building has good insulation for the floor. In addition to this, the gaps between the floor as well as the skirting board may also require insulation. This is to help reduce potential cold drafts.
What are the benefits of floor insulation boards?

- With less heat escaping, it will have a positive effect on the global warming and climate change, making your property more energy-efficient and sustainable.
- When installed correctly, roof insulation will have a lifespan for as long as the building itself.

Installing floor insulation boards
Solid floors can be insulated by laying the insulation on top. A damp-proof membrane is recommended to be placed in between the solid floor and insulation board to prevent moisture. Other materials can then be layered on top of the insulation to help with noise such as an acoustic barrier matt followed by underlay.
Concrete floors can be insulated by infilling sand over the surface and then laying a damp proof membrane on top of the sand, then lay the insulation boards and then the concrete. Then apply the underlay and chosen flooring.
Floor insulation boards can be cut by measuring the boards and marking a size guide. A fine-toothed saw can then be used, or the boards can be scored with a sharp knife, snapped over a hard edge, and scored on the other side.
Ensure a building professional is consulted before installing floor insulation. This is to ensure the insulation materials being used are the correct product for the building, this will avoid damage being caused. Always ensure the product meets the relevant national building regulations
If there is existing dampness or rot within the floor this should be cleared by a building professional before the insulation is installed. Insulating damp or rotten areas can cause further damage.

The boards come in a variety and thicknesses and offer thermal conductivities ranging between 0.018W/mK and 0.022W/mK.

For rigid foam insulation, it needs to be about 90mm in thickness and for mineral wool, the thickness needs to be at least 150mm. A U value of 0.25 needs to be achieved. Additional factors in the actual construction of the building may affect U Value. To be certain, the best thing to do is contact a builder or architect to review your specific requirements.

How is underfloor insulation installed?
There are multiple application methods that can be applied when insulating your floor depending on the type of insulation you need, size, and where abouts in the floor structure in which it will be fitted. Floor insulation can be applied in suspended floors, solid floors, and concrete floors.
Insulation for suspended floors
Underfloor insulation can be applied in suspended floors by going underneath the floors into a basement space and fitting insulation into the joists and securing using netting material.
A suspended floor is when there is a space beneath the floorboards and that the floorboards are laying over joists.
If there is no basement the floorboards should be lifted, and insulation fitted into the joists. It can also be applied by fitting netting in between the joists first and then placing the insulation on top of the nets.
Insulation for solid floors
Solid floors can be insulated by laying the insulation on top of existing flooring and then covering the insulation with the chosen floor finish. A damp-proof membrane is advised to be laid in between the solid floor and insulation boards to avoid moisture.
This method is not always recommended as it can affect the rest of the properties fixtures and fittings such as raising skirting boards, raising electrical sockets, shaving the bottom of doors and that’s before clearing out the whole space and pulling up the floorboards.
There are several insulation manufacturers that provide underfloor insulation such as Kingspan, Celotex, Iko Enertherm, among others.
Underfloor PIR boards
Underfloor PIR insulation boards are manufactured from rigid polyisocyanurate (PIR), a lightweight foam board sandwiched between two foil facings. It is a lightweight product to ensure easy cutting, handling, and application. It provides a multi-purpose use including, walls, roofs, and floors. It is a much-liked product when insulating floors.
