Insulating a floor can cause your home to lose up to 15% of its heat. Protect both the ground floor and upstairs rooms above the heated areas. According to the Energy Saving Trust flooring insulation can reduce heating costs by as much as PS65 and carbon dioxide emissions by as much as 290kg per year.

You have many options available if you are looking for a cost-effective solution to your cold home. Many of them are simple to install. You can insulate your entire home, but it could be expensive. It’s better to include this in any other renovations. Get your solid walls insulation from the UK.

What should I look out for when installing flooring insulation?

If you are looking to do the job yourself, it can be quite daunting. It is important to plan carefully and have a good understanding of the materials. It won’t produce the desired effect if you put too much.

Unexpected costs could occur. You might find flooring boards or joists that are rotting or damaged and need to be replaced.

Building Regulations

You must follow all building codes in your area before making any major changes to your home’s structure. If you are removing more than half of your floor, you will need to insulate it to at least 0.25W/m 2K. This is even if you don’t plan to. This is typically possible by using 100mm or 150mm quality foam insulation. However, the number of layers will vary depending on the structure and the floor area.

It is important to ensure that there are no damp areas where insulation will be installed. This will help prevent future problems like mould or decay (Link for IN7).

You should also determine the type of flooring you are using. Older homes have more inclined to have elevated flooring (floorboards that have been placed on joists with crawlspace underneath), while newer constructions have concrete flooring. Most likely, your home will have an opening or cellar that allows you to see underneath the floor. In the absence of an opening or cellar, you may need to lift the carpet to expose a corner or the underlay.

Quick fixes

A polyfoam or ultra-thin insulation board, which is either a foam board or underlay, can be used to protect your flooring. This is a simple and easy way to protect it. Multi-foil floor insulation underlay is a way to reflect heat into your home, without raising the floors too high. Although they are more costly than mineral wools or rigid foams, they can save you the time and effort of removing old floorboards from your home and digging through concrete foundations.

You should ensure that the thermal underlay you choose has a high tog rating (or R-value) as these are measures of heat resistance. If you have underfloor heating, the underlay will prevent heating from rising through the flooring.

The thickest carpets and rugs can help keep cold air out.

Suspended and elevated floors

Most older buildings have a suspended floor structure in which floorboards are attached to joists above an empty space (or “crawlspace”)

If you have access to the crawlspace beneath the floor the job will be easy. You can place the blankets or boards between the joists. Semi-rigid insulation can be installed using friction or by attaching battens to the opposite side of the joint. Blanket insulation can be held up using netting or tacks that are inserted into the joint. To add padding or blocking, solid board insulation can be attached to the lower joists in the event of limited space.

Accessing insulation from underneath requires more labor due to the removal of floorboards. You may need professional assistance. If you plan to renovate simultaneously, it is best to get professional help.

To minimize damage, if you don’t plan to replace the entire floor, lift only the floorboards at once. The alternatives to lifting the floorboards from the ground are the same as installing them from the bottom. There are two options: attach semi-rigid insulation boards or slabs to the floorboards. Secure the rigid insulation with tacks or fix the netting at each floor joist’s top. Make sure it forms a trough in between the two joists. Blanket insulation can then be used to fill the voids left by the nets. This is a great way of insulate any underground pipes you have.

An environmentally-friendly insulating material is cellulose because it has a significant recycled content (75 percent is recycled fibres of paper). To function as netting, insulation made from loose fill must be sealed with a membrane. It’s cost-effective and efficient in keeping heat inside.

Although the cost of having an installer install suspended floor insulation varies, it is recommended that you spend approximately PS95 per square meter.

How much insulation do I require?

The majority of insulation can be installed in a larger area. However, you shouldn’t compromise the integrity of the insulation. Insulation made from wool-like material, for example, has tiny air pockets within the fabric. The air inside acts as a heat barrier by trapping heat. Insulation won’t work as well if it isn’t tightly packed.

Construction regulations for new homes require a floor’s upper U-value of 0.13W/m2K. This is a measure of thermal resistance. Your home’s U-value will depend on the type of flooring you use (concrete, brickwork, and insulation that is already in place). However, it is important to keep this value within the range of 0.13W/m2K when choosing the insulation, you will use.

Underfloor ventilation

It is crucial that insulation doesn’t block any ventilation in the crawlspace. Clear any obstructions in the wall. The accumulation of carbon monoxide or decaying floors could be serious consequences from blocking air filters or grilles. It is possible to prevent cold drafts from entering the floor by using sealants and caulking to close any gaps between the skirting boards and the floorboards.

Solid Floor

Insulating solid floors requires you to be cautious. Raising the floor’s level can cause more work (trimming doors, refitting radiators and wiring sockets, etc.). This will result in a higher price and a more expensive product.

Insulation is usually applied to solid floors above the concrete layer. Concrete (a mixture cement and sand) layers are covered by insulation. Based on the floor’s dimensions, 150 to 200 millimetres worth of insulation is required. To complete the look, the insulation should be placed between a layer of damp-proofing below (to prevent moisture accumulation) and chipboard above. This arrangement is known as a floating floor.

Sub-solid floor insulation is not recommended if the original floor is being replaced or renovated. This is because you have to remove the screed layer or old flooring, then put in the insulation in thick layers and then add a thin layer. This insulation method is the most extreme. This is an economical heating method that can be used if you are looking to remove an old screed layer.

Modern homes already have insulation installed beneath the concrete floor. Concrete is capable of efficiently absorbing heat and storing it, which means that your house will stay warm longer in the night.

Similar to elevating floors, sealing the edges of walls and skirting boards with sealant is an efficient and cost-effective way to ensure that your floor is properly insulated. Ecogenius LTD has approved installers. Click the link to verify your eligibility for the solid wall insulation grant.
