How To Properly Insulate A Floor In A Conservatory Project


How To Properly Insulate AFloor In A Conservatory Project By insulating your conservatory floor you are basically ensuring the room will lose as little heat as possible which will enable you to use the conservatory all year round. No matter how many radiators you add into the room if it hasn’t been properly insulated it will not hold the heat you add to it. You should add the floor insulation during the construction of the conservatory base; if it is not addressed at this stage then you will have to undergo a costly renovation later on.

In this article we will explain how to properly insulate your conservatory floor using solid insulation boards and under floor heating,which in the long run will help you to save money on your energy bills plus allowing you to use the room all year round.

The conservatory base is one of the most important stages in the build of any conservatory, many factors need to be taken into consideration; the ground conditions, footings, drainage, brickwork and of course the floorinsulation and heating options.

When it comes to insulating the conservatory floor we recommend using Celotex Insulation Boards, the boards are made from Polyisocyanurate also known as PIR Boards. The product is very user friendly as it is easy to cut and shape which makes it ideal for people who are doing a self-build. It also has the benefit of being recyclable, provides fire protection and is easy to install.

Using under floor heating within the conservatory is becoming more and more popular with home owners. This is probably the most expensive option to go for when it comes to heating the room, but gives the best results as well as making the conservatory useable all year round.

Insulation Cart offers a range of insulating products for the underfloor heating projects from Celotex and Kingspan manufacturers.

By installing under floor heating you will have the advantage of not fitting unsightly radiators which also take up wall space and have the ability to heat the room from the floor upwards. Under floor heating is also a more eco-friendly solution to heating your conservatory compared to using radiators it is also nice and warm to walk on!Img

The Basics Stages Of How A Conservatory Floor Is Constructed:

  • The site is checked to make sure there are no obstacles such as drain pipes, boiler flues or extractor fan outlets where the conservatory will be built. Consideration should be given to the position i.e. which way the room will face.
  • The foundation and the footing work takes place.
  • The damp proof membrane is added to protect the floor.
  • The solid floor insulation (e.g. 100mm Celotex GA4000) is now laid;this goes below the concrete slab.
  • The concrete floor is now poured into the conservatory.
  • At this stage the rest of the conservatory would be constructed to make the room water tight.
  • Next comes the under floor heating which can be either water or electric powered.
  • The floor is then screed to provide a completely smooth and level floor.
  • The finally stage for completing the floor is to add the finished flooring, such as wood, laminate, tiles, carpet etc.

Whether you are doing a Self-Build Conservatory project or employing a builder for the construction of the conservatory base it needs to be correct. If it isn’t assembled properly you will have no end of issues with your conservatory and in the long run will be looking at a costly renovation.

We strongly advise that you take particular care and attention to the floor insulation and also use under floor heating for the best results of heating your conservatory.

One major benefit of installing a conservatory to your property is to be able to use it all year round and without the right insulation/heating then using the conservatory comfortably in the winter months will not be possible.

Building regulations in your area will tell you the bare minimum required for proper insulation, but it's always advisable to exceed these recommendations for the best results possible.
