Stop heat escaping through your floors

Cold floors are a sign of heat loss

If your floors feel cold underfoot, or rooms above uninsulated floors never quite feel warm, there is a good chance heat is escaping through the ground or ventilated voids under the floor. That means higher heating bills and rooms that cool down quickly when the heating switches off.

Premier Insulations surveys your home to identify where floor insulation will make the biggest difference and recommends solutions that work with your existing construction and finishes.

Floor insulation solutions we provide

  • Suspended timber floor insulation — insulating between and under timber joists to reduce cold floors and draughts from ventilated voids.
  • Solid floor insulation — adding insulation as part of new screeds or full ground floor refurbishments.
  • Room-by-room upgrades — targeted insulation in the coldest rooms, such as living rooms and ground floor bedrooms.
  • Retrofit & re-insulation — improving or replacing older, poorly performing floor insulation where access allows.
  • Linking floors with other upgrades — combining floor insulation with attic insulation, cavity wall insulation and external wall insulation as part of a wider retrofit plan.

We will confirm which floor insulation options suit your home best during your free survey and provide a clear, itemised quotation.

certification
  • Warmer floors

    Less of that “cold underfoot” feeling, especially on ground floors.

  • Fewer draughts

    Reduced cold air moving up through gaps in floorboards and skirtings.

  • Lower heating bills

    Less heat lost into the ground or unheated voids

Is your home suitable for floor insulation?

We assess how your floors are built before recommending work

Not every floor is insulated in the same way. Some homes have suspended timber floors with a ventilated void underneath, others have solid concrete slabs,
and many have a mix of both. During your survey we check:

  • The construction of your ground floor (timber, concrete or a mix).
  • Access to the underside of floors or potential routes from below.
  • Existing insulation, if any, and its condition.
  • Floor coverings and how much disruption any upgrade might cause.

If floor insulation is not practical in certain areas, we will explain why and focus on other measures such as attic insulation, cavity wall insulation or internal wall insulation to improve comfort.

What customers say

“Before the work, the sitting room floor always felt cold, even with the heating on. After insulating the floor and upgrading the attic, the whole downstairs feels more comfortable and the boiler runs less.”

– Homeowner, semi-detached house, Co. Sligo

“We had timber floors over a draughty void. Premier Insulations explained the options clearly, insulated from below and left everything tidy. The difference in comfort is huge.”

– Homeowner, bungalow, Dublin

Floor insulation and SEAI-supported upgrades

Floor insulation is often included as part of deeper home energy upgrades, especially where a full ground floor refurbishment or major retrofit is planned.
In some cases it can form part of SEAI-supported projects when combined with other measures.

As part of your survey, we will look at how floor insulation fits into your overall upgrade plan and advise on:

  • Whether floor insulation is practical and cost-effective in your home.
  • How it can be combined with attic and wall insulation upgrades.
  • Potential grant support through SEAI schemes for qualifying projects.

For more information on current supports, see our insulation grants and Home Energy Assessment & BER pages.

Linking floor insulation with other upgrades

Floor insulation is most effective when combined with other fabric improvements. Many homeowners choose to upgrade:

We can help you plan a sensible sequence of upgrades that fits your budget and any future renovation plans.

Insulation, heating controls and comfort

Once your floors, walls and roof are performing properly, your heating system and controls can work far more efficiently.
Well-insulated homes are easier to heat with modern systems such as heat pumps and respond better to smart controls.

Floor insulation – quick answers

How do I know if my floors need insulation?

Common signs include floors that feel cold underfoot, especially on the ground floor, rooms that cool quickly once the heating turns off,
and noticeable draughts around skirting boards. A survey will confirm how your floors are built and whether insulation will help.

Can you insulate suspended timber floors?

Yes. Where access allows, we can insulate between and under timber joists to reduce heat loss and cold air movement from the ventilated void below.
The exact method depends on access, ventilation and the condition of existing materials.

Do you need to lift my floors to insulate them?

It depends on how your floor is built and what access is available. In some homes we can work from below, through an underfloor space.
In others, limited lifting of floorboards or finishes may be required. We will explain the options and likely disruption during your survey.

Will floor insulation make a big difference on its own?

Floor insulation can significantly improve comfort in rooms where cold floors and draughts are a problem.
The overall impact on your bills is greatest when floors are upgraded alongside attic and wall insulation as part of a wider plan.

Is there much disruption during installation?

We plan the work to minimise disruption, but some access is always required. This may involve moving furniture, lifting floor coverings or working from
underfloor spaces. We keep you informed, protect surfaces and leave areas tidy at the end of each day.

Are there grants available for floor insulation?

Floor insulation can sometimes form part of deeper SEAI-supported retrofit projects, especially where a full ground floor refurbishment is planned.
Grant eligibility depends on the overall upgrade package. We will advise on current options and direct you to our
insulation grants and energy upgrades pages for more detail.
