Eco Loft Conversions
(ideas and inspiration)

Ideas and inspiration for an eco loft conversion

It’s often an underutilised area of the house but a loft conversion can be the perfect solution if you want to create some much needed space in your home. Cheaper to implement and with much less upheaval than moving, a loft conversion can give you that handy extra bedroom or the workspace you’ve always wanted and if you use eco-friendly materials as well, you’ll be benefiting from a whole lot more.

Did you know that by using Eco Friendly materials you can…

  • reduce your construction costs
  • reduce subsequent energy costs
  • create a healthier living space
  • be kind to the environment
Andrea has been researching the best materials she could use for a loft conversion blog post about insulation values. Read about her findings here: Eco Loft Conversion Ideas & Inspiration.

Let's talk about insulation values!
(or "how much insulation do I need?")

How much insulation do you need?

The short answer is, it depends ...
If you just want to reach the minimum standards for insulation, the answer depends on:
  • what type of building you are insulating (domestic or non-domestic, new build or refurbishment), 
  • where you need to insulate (walls, roof, floor etc), 
  • how the building work is constructed (materials used etc) and,
  • location of the project in the UK (the rules are can differ for England, Scotland, Wales and Northern Ireland!).
The good news is that all the insulation calculations, wherever you are in the UK and whatever your are doing, are based on "U-Values". The key is to understand U-Values and how they are calculated.

Read Ian's blog post about insulation values to really get to grips with thermal conductivity, R-Values and U-Values. He kept it simple, honest.

Quick Guide to Breathable Membranes
(VCLs, VSDs, Water Vapour, Dew Points and Condensation)

Which membrane to use

If you are considering insulation for your property, no doubt you have come across terms such as VCL, VSD, vapour barrier and breathable membranes to name but a few. We’ve put together a quick overview and a brief explanation of the main types of membrane and their application.

Some terms, such as vapour control layer (VCL) are sometimes used as a collective term for materials that control the passage of moisture. As such VCL often describes two types of membranes that do two very different things. So it's important to understand how the moisture moves and where it needs to be controlled.

Read Ian's blog quick guide to breathable membranes to understand a bit more about it all.
