    I am currently looking to renovate, extend and add first floor to my bungalow in Bournemouth.
    Whilst doing this I would like to increase the property’s green credentials as much as my budget will allow. I have cavity walls but would like to bring them to a renovation u value.
    I have been looking for suppliers of external wall insulation but drawing a blank in this area, my architectural technician is suggesting internal insulation and cavity wall insulation but don’t really want to lose the space and my understanding is external wall insulation is better due to potential issues with condensation with internal insulation and cavity wall insulation.
    Current build is brick cavity walls with timber suspended floors, 4 inch joists around 350 centres
    Also trying to decided between insulating between the joists and using spreader plates for underfloor heating or taking out the joists, using hardcore to fill void (around 500mm) insulation and screed system.
    I would like to use bamboo flooring throughout the house.

    Can anyone help please?

    Main questions
    Any external wall insulation suppliers in Dorset?
    Is worth paying the extra for external wall insulation I will need to render with a 0.7 m band of brick slips (planning permission). I have got one price from Welsh company of around £15,000. They will install from ground level to soffits, have asked for Kingspan kooltherm to keep insulation to 50mm to reduce amount soffits would have to be extended.
    Any advantages/disadvantages to the different ufh system for ground floor.
    If I go with screed can I use eps for insulation in the floor rather than celotex to reduce the required amount of hardcore ( my understanding is this would require me to double the thickness of insulation to 200mm but not sure if it would take the weight)

    Hello Sarah, and welcome to the forum.

    I can't help with suppliers local to Bournemouth or prices I'm afraid. But yes you can use EPS under your floor. My whole house is stood on 400 mm EPS. I also have bamboo flooring and am very pleased with it.

    Yes, EPS sheets for EWI and you must also fill the cavity with say graphite EPS beads to eliminate thermal bypass.

    EWI should go down into the ground as far as possible,

    If I were you I would forget hardcore and fill the void with eps sheets, possible concrete and screed on top or a floating floor.

    Bamboo sounds nice, if you go floating floor I would recommend a system to clip pipes into and t&g ply rather than chipboard under the bamboo with osb as a cheaper alternative.

    Hi Sarah I’m half way through a deep retrofit in Bournemouth and now have a newborn so I am very familiar with the challenges, technical and emotional, haha! Would you like to come round to my building site? I could offer lots of advice as you can see a similar house stripped right back to bare basics!!
