Floor Insulation
If you are thinking about how to insulate a floor you are at the right place as in our store, you can get top-quality floor insulation materials which will help you to make your home a warm, energy-efficient, and cosy place for living.
While the floor is not insulated, and this is a common issue for old houses, it allows heat to leak through the floor gaps. Besides, in winter, the soil tends to frost and provide extra cold to the house. This refers to suspended floors, and it’s true for other flooring types as well because heat can be easily distributed to the ground through any flooring type, while floors without insulation freeze and make the environment inside the house colder and your heating bills higher.
Floor insulation is typically installed beneath the flooring to reduce heat leaks by sealing the surface with energy-efficient and durable materials like mineral wool, glass wool, or foam materials. This solution helps to make cold spots warmer, and it suits almost any type of flooring whether it is a concrete floor, a carpet flooring or any type of wooden floors.
Just to help you to understand the efficiency of floor insulation, look at the figures which enclose the essence of this renovation solution.
- More than 20% of heat is wasted in houses where floors are not insulated.
- Carbon footprint minimization reaches 240 kg per year when you insulate floors in an average house.
- Floor insulation materials cost somewhere about £150 per an average home and this money can be paid off in 24 months.

What is Floor Insulation
The whole idea of floor insulation is to create an additional layer beneath the floorboards or any other type of flooring. This part of renovation can be done using special insulation boards which provide the necessary functions when installed.
When you decide on how to insulate floors in an old house or your cottage, there are a couple of features to consider in advance.
- Low thermal conductivity of the material, as you need to save heat from leakage through the floor.
- A high density of the material combined with elasticity creates an integral surface which will protect floorboards impeccably.
- Long service life – as usual, the floor insulation project is developed during home renovation, and probably, you do not plan to renovate your home annually, so the more durable is floor insulation, the better is for you.
- Environmentally-friendly material is also a must if you want to maintain an eco-friendly lifestyle.
- The ease of installation. This is important in both cases if you want to try your hand at DIY floor insulation and in case you decide to employ a contractor, as the complexity of installation will bring you additional costs.
According to these features, today the most popular types of floor insulation materials are glass mineral wool, polystyrene, and PIR materials.
Specifics of Floor Insulation for Different Types of Flooring
In our store, you can purchase floor insulation materials for different floor types. Typically, insulation projects are used to insulate ground floors or first floors in flat blocks and ground floors which have a basement or a foundation which is not raised.
For floor insulation, we offer you to use some pieces of advice from our consultants to prepare for the project implementation properly.
- Please, calculate the overall weight of the flooring pie so as not to overweight interfloor overlapping and cause its collapse or damage.
- A correct calculation of heat leaks is the way to choose the best floor insulation material and its thickness.
- If you have to insulate floors in a house with low ceilings, you need to pick the material with the lowest thickness, for example, polyurethane foam material.
- Please, keep in mind the fire rating of the material, especially when you decide to insulate wooden floors. You can filter non-combustive types of insulation in our catalogue.
- For concrete floors, you need to remove all the flooring and lay a crate, on which the layer of insulation will be installed. Then it is necessary to install a layer of waterproof membrane, and a subfloor layer on it. Then you can install any finishing flooring of your choice.
According to these pieces of advice, you can use convenient filters in our catalogue to select the best floor insulation material for your home.
Types of Floor Insulation
Besides choosing good flooring insulation materials, you need to consider which goals you have to pursue in your floor insulation project, and which types of floors you are going to insulate. Just have a look at our most popular types of flooring insulation to select the proper one.
Acoustic Floor Insulation
The main intention of acoustic floor insulation is to reduce the impact of noises in houses. This type of insulation helps to solve a couple of problems at once. It helps to increase soundproofing in neighbouring premises, and it also saves heat and protects the floor from heat leaks. In our catalogue, you can select the most effective and durable rolled acoustic insulation materials to isolate your home from neighbours’ noises and outer sounds. We offer a wide choice of slab materials with thicknesses from 25 mm to 180 mm by world-known Knauf and Rockwool brands.
Concrete Floor Insulation
Concrete floors are durable, but they are cold, and they need additional insulation to provide comfort for feet and maintain a warm environment in the house. We offer a good range of materials for maintaining your request on how to insulate an existing concrete floor in the UK. When you add an insulation layer to the concrete slab and a moisture-proof membrane, it works for your home’s comfort. There are over 170 products for concrete floor insulation available in our store including expanded polystyrene boards of different thicknesses and PIR boards by Kingspan, Celotex, and Jablite.
Suspended Floor Insulation
Suspended floors are whimsical in their maintenance. When you decide how to insulate wooden floors, you help your flooring to prolong its service life by adding a layer between boards and wooden joists. Besides, the layer of insulation seals the gaps between timber boards and creates an integral surface which won’t let heat through it. There are various types of suspended floors insulation in stock including PIR boards, rock wool plates, and boards of expanded and extruded polystyrene.
Underfloor Insulation
Underfloor insulation can be used for different flooring types, and they are typically installed under the finishing layer of flooring. There are diverse types of underfloor insulation you can pick in our store, and you can use it during your renovation routines or while flooring replacement. We offer over 200 products in this category to fulfil the requirements of every customer.
Floor Insulation Benefits
Considering how to insulate my floor, it is better to get through the main benefits which you get after you provide your floor insulation project. These are as follows:
- Floor insulation helps to reduce heating losses in the cold season as it provides an additional layer between the upper flooring and basement and doesn’t let heat through it.
- When you decide to insulate your floor, you save money on heating and air conditioning. An insulated floor provides a cooler temperature inside the premises in summer and a warmer microclimate in the room in winter.
- All types of floor insulation improve the soundproofing of the house.
- You can make your flooring service life longer when providing its insulation.
