Floor Insulation - What type of Flooring Insulation do we need?

Floor insulation is a simple and effective way to keep your home warm and reduce your energy bills. There are two main types of floor insulation - underfloor insulation and over-floor insulation. Underfloor insulation is installed between the joists on your floor, while over-floor insulation is laid on top of your floorboards.

Floor insulation can be made from a variety of materials, including:

* Polystyrene

* Polyurethane

* Sheep's wool

* Mineral wool

* Glass wool

* Expanded polystyrene (EPS)

Insulation is the key to making your home more comfortable. With polystyrene as one of the two most common types, it's easy and affordable for you! These insulations are both durable yet flexible which makes installation quick - but don't let that fool you because they still provide great thermal control in cold weather conditions too.

Insulating your ground floor is a great way to keep your property warm. Generally speaking, you only need to insulate the ground floor. If you’re on an upper floor, you don’t usually need to insulate your floor space as. the heat will rise from the floors below.

Some benefits of Floor insulation that give home energy advice:

  • Reduces Home Heat Loss i.e. keeping your home at a constant temperature helps save energy.
  • Improving the efficiency of your heating system that will help to reduce your fuel bills and carbon emissions.

When it comes to insulating floors, it can be difficult to know what type of insulation you need, especially when embarking on a renovation project. Before checking for the correct insulation first we need to check what type of floor do we have? 

Many homes especially those newly constructed have a ground floor made of solid concrete. Older homes are made of suspended timber floors. If the floor is a suspended wooden floor, you can probably see wooden joists and the undersides of the boards. 

Insulating floors are often more difficult than insulating other areas of the building. The ground floor under a house is usually warmer than the air around it. 

Ways to Insulate your Floor:

  1. Insulating Floor - Solid Concrete
  2. Insulating Floor  - Suspended Timber
  3. Insulate around Pipes & Radiators 
  4. Seal Gaps 

Tips to remember when insulating your floor:

* If you have a suspended wooden floor, you’ll need to fit your insulation between the joists. You can use rigid boards or rolls of flexible insulation.

* If you have a concrete floor, you can either insulate it underneath it or on top of it. Insulating underneath is generally more effective, but it can be difficult to access the space. You might need to lift up floorboards or remove flooring to do this.

* It’s important that your ground floor is well ventilated to prevent dampness and condensation. Make sure there are air vents on your floor, and that all air gaps and cracks are sealed properly.

* Remember to check for any cables or pipes beneath your floor before you start installing your insulation. You may need to move these temporarily, or find another way to insulate around them if they can’t be moved.

With the right materials, it's easy to insulate your ground floor and keep that home warm all year round. Whether you prefer underfloor insulation or over-air layers; the benefits are clear - improved energy efficiency as well as reduced heating costs! 

You should not block up any air bricks in your walls. These will help ventilate the space under and stop floorboards from rotting away! If you have a basement, take special care to look at where there are wooden joists or foundational support structures for this type of durable surface material because if it is installed properly then these exposed surfaces can remain intact even after an emergency situation such as fire damage occurs due both their high strength but also durability over time when compared with other types like carpeting which melts into itself upon heating sources becoming too intense.

Timber floors can be insulated by lifting the floorboards and laying mineral wool insulation supported by netting between the joists.

In the winter, timber floors can make your home cold and uncomfortable. But there's an easy way to keep them warm! Insulating under floorboards on ground level could save you £75 per year in a typical house or up to £130 if living with a detached garage- this cost-effective insulation option does wonder for reducing noise from above while keeping heat inside where it belongs - making life more comfortable at night time too.

Can any Floor be Insulated?

The main sources of heat loss in homes are wooden floors and draughts that enter through the cracks between floorboards, skirting boards, and pipes. Both wooden and concrete floors can be insulated. 

Generally, you only need to add floor insulation to ground floors and then you can supplement this with loft or cavity wall insulation.

Floor Insulation Board

Insulation boards are among the most popular forms of floor insulation. Most floors are suspended floors, which means there is a space between the floorboards and the surface below - the floorboards will rest on joists. Board insulation is easy to cut, and handle and can be used on floors and walls. 

Floor Insulation boards are the most popular for flooring insulation because they come in rigid boards that can be easily cut into desired shapes. In addition, the insulation panels are incredibly light and relatively thin, while still providing a high degree of insulation.

Floor Insulation Roll

Floor Insulation rolls are multi-purpose, flexible, non-combustible, and designed especially for installation by friction fitting. They provide better thermal performance than standard loft rolls and best fit for studs and joists.

PIR insulation board

Polyisocyanurate (PIR) insulation board is a thermally insulating material. It is made of polyisocyanurate resin, which is a thermoplastic. PIR insulation board has a low thermal conductivity and a high R-value.

The PIR board has a low emissivity foil face to improve thermal performance and optimize space in construction especially when designing or building cavity spaces. These Celotex insulation boards are known for achieving U-values with minimal thickness, which means they can be installed easily without sacrificing the warmth of your home!

Suspended Floor Insulation

Suspended Floor insulation is one of the leading causes of heat loss in older homes, but there's an easy way to prevent it and keep out the cold. 

An insulation suspended floor can lead older homes sacrifices their energy efficiency by letting cold streams through the walls easily; however, there are ways around this problem with proper installation of said material that will keep out distractions like drafts while still providing excellent thermal retention capabilities resulting either significantly low utility bills Or even better yet: improved indoor air quality due to increased vapor diffusion rates which means cleaner breath outdoors too!

Ground Floor Insulation

Ground floor insulation prevents unnecessary heat loss in buildings. They can help maintain a comfortable temperature and improve energy efficiency. With no insulation under the edge, the floor’s direct contact with the ground makes it an easy winter path to entry. 

How much can you save by insulating floors?

Insulation can save you money! By insulating the floor, we're able to stop heat from escaping through our homes. This means that by installing some loft insulation and then taking care of other important factors like closing windows before they reach too high temperatures in the summertime; homeowners could easily see an increase in their monthly utility bills by up to £60 - 85 per year (or more). Insulations will also help lower absolute temperature fluctuations within a building which is good for everyone who lives there.

A typical suspended floor installation could cost you between £ 1,300 and £ 2,700 depending on the circumstances. Solid floor insulation could cost a lot more.

How to Insulate Solid Floor? 

There are many benefits to solid floor insulation. It can keep your home warm in the winter and cool in the summer, saving you money on your energy bills. It can also help reduce noise pollution from outside. The insulation is laid on the concrete and covered with a screed. There is a vapor barrier under the insulation, and depending on the type of screed, there may be a second above it.

If you're looking for a way to improve your home's energy efficiency, solid floor insulation is a great option.
