    Hi Mr Chibs, Thank you I had a look but the calculator is for cavity walls and we haven't got those :(

    Insulation - Cost vs. Benefit - Walls or flat roof

    Hi phatboy, thank you for your thoughts. Interesting that your neighbour is choosing to use 9" Thermalite and then add EWI, rather than building a cavity wall and insulating that. I thought the better option was always to do a cavity wall if possible. Do you remember the make of the EWI you had...

    Insulation - Cost vs. Benefit - Walls or flat roof

    WGT52 - Thank you for the reply, sorry I don't know much about building so not sure what a fall is on a roof. Do you mean a slight slope? If so then yes it is not totally flat there is a bit of a slope to it. We don't know what the roof construction is and the builder who put in our loft...

    Insulation - Cost vs. Benefit - Walls or flat roof

    Mr Chibs - Thank you glad your house is warmer. Planning to hopefully stay put for the long term so should be worth it to do something. My concern regarding the bricks is that the bricks are not what is causing that section of the house to be cold, and that the true cause is instead the fact...

    Insulation - Cost vs. Benefit - Walls or flat roof

    To add, what I am trying to work out is where we will get most bang for our buck if you like. If adding EWI to walls built out of Thermalite blocks will only make it a little bit warmer then that £2k would be better off saved and put towards the roof. :confused: However given that upstairs...

    Thank you MeldrewsMate, it is indeed a huge shock and also a huge lesson learned that we didn't pay close attention to the walls etc. before buying the house! I assumed that since it was built in 1996 it would automatically be well insulated, apparently not. I did get a reply from the Building...

    Insulation - Cost vs. Benefit - Walls or flat roof

    Thanks so much IT Minion, really appreciate your thoughts. Yes, the 11k is to fit a Bauderflex warm roof system and its £11,220 so even more! The roof area is 9.3m width x 4m depth so roughly 37 metres squared. We're just inside the M25 so should probably factor in location. Does that still...

    Insulation - Cost vs. Benefit - Walls or flat roof

    Hi, We live in a semi detached house built in 1949 which has a double storey side extension that was built in 1996 to add a garage and additional reception room on the ground floor, and a bedroom and bathroom upstairs. The bedroom and bathroom are above the garage, however the reception room is...
