Insulation of Flat roofs
Do you get confused about insulation?
Let me try and guide you through this.
Over the past 5 years or so, the Kyoto Treaty has begun to force the western world into re-thinking its position with regard to the environment, and guidelines for emissions have been set. I won't go into those guidelines at this point.
Part L of the building regulations set out the amount of insulation that is to be used, so that any new build or refurbishment of a property is carried out to reach the new heat loss standards. As our interests here are to do with roofing, and particularly flat roofing, I will try and keep to information on this area. Let's start to break this down.
New building projects encompassing new flats, houses, offices and so on - "New Build".
Renovation works, which are old properties that are being refurbished - "Refurbs".
The regulations are different for each and I will go into both over the next days.
The best place I have found that explains the regulation for "Refurbs" is Sheffield Insulation
The issues you will need to get to grips with are.
- Depth of insulation required
- Type of insulation
- Condensation risk Analysis
Calculating the above is further complicated if the existing roof makeup and insulation is unknown
