  1. Thanks-you for the kind replies folks, its not looking good for the ol UFH........big but - I had a chat to my builder, we could raise the height of the door frames to help accommodate. So maybe something like max 90mm profile (all included): 50mm celotex insulation 7mm superfoil insulation Some type of side insulation on edges of all rooms 15mm overlay UFH system 16mm floor finish I would go for using more tile floors in the heavily used rooms as they are better conductors and hold more heat - would the above be do-able in the context of I still expect 20%+ heat loss downards. Is there a supplier whose overlay solution is better at insulating or raw efficiency than others? Most of them claim their solution has "insulation already provided" in the overlay boards!
  2. Hi folks Just your friendly neighbourhood UFH newbie here - I'm hoping you can help me out with some advice...I've spent HOURS researching and still cant come to a decision *my mind is gonna blow!!!* We really would like Wet UFH in our Bungalow that is undergoing renovation (has a combi boiler radiator system), the key concern is keeping the profile as low as possible (only 78 inch height on the doors openings) and ensuring the system is still efficient and affordable. The floor of the house is concrete, think there is no insulation in there since it was built like 50+ years ago. The other insulation is average (double glazed, cladded roof with some ceiling insulation 20mm) and there is only the one floor with ceiling + roof. But the main living room and dining room area will have a row of bi-folding doors. We would be finishing half the house in carpet and the rest in tiles/laminate. To try and keep the profile low (max 65mm profile), an overlay system seems much better at only 15-22mm depending on the supplier. 1) Is an overlay system going to do the job heating up the house? My research and the suppliers says the heating will be ok, but surely the heat-loss due to no insulation in the concrete below will be substantial and kill my energy budget *scary*. 2) Will adding in some insulation help with this? E.g. layering upwards: 30mm Celotex 18mm Overlay UFH system 20mm floor finish carpet/laminate/tile Will adding a 7mm superfoil (space age looking stuff) high thermal resistance layering be a worthy investment over Celotex? 3) Would side insulation, like a foam or celotex like material make a big difference? I've read some comments that this makes a nice difference? 4) Are there any good quality for the price suppliers anyone can vouch for? I have looked at like 7-8 and really can't tell which once offers the best advice + product (Wunda, NuHeat, Continental, theunderfloorheatingstore, Warmup etc) 5) Maybe going with some kind of 40mm screed + 20mm floor finish is best (no insulation underneath?) Thank you so much!
  3. Thank you for the quick and great advice. I will be getting an architect in to confirm the above and try some ideas out within the limits of the PD regs! Cheers
  4. Thank you for the awesome replies! To clarify, we are in West Yorkshire and the current extension is considerably less than 50% of the floor area of the house (maybe around 20%) and I don't think it needed planning permission. Yeah for any work to the windows, I would be hiring a structural engineer and going through BC! That planning advice service looks very useful thanks. So - regarding the planning - enlarging the current 2 windows to either 1 long bi-fold glass door or 2 sets of enlarged (+ 50cm-100cm each window) Bi-fold doors - I probably don't need planning? And to enlarge the current balcony to the one in the diagram - if any part of the whole balcony (including the current balcony you can see in the picture) sits on a stable garden area <300mm I probably don't need planning? Cheers
  5. Hello friendly people, I'm hoping you can help me out with some advice...mostly for the peace of mind before any next steps. We want to do a few updates to our bungalow, 1) Extend the current Windows (to bifold doors) at the front of our house, there are 2 windows about 2m wide each, 1 of them runs nearly floor to ceiling whilst the other is around 70%. 2) Extend the balcony (stone built) with a wood patio about 2.5m out and 6m to the left. To clarifyit is a detached Bungalow nearer to the countryside....so only the backside has any neighbors and they are literally in other streets (+50m away) and as the Bungalow is on a hill we are already looking down on them with the existing windows/balcony. I've spoken to a builder (briefly) and he has advised I don't need planning permission to remove these windows and replace with bi-folding patio glass doors as the current large windows are already there and as this is an old single story flat roof extension with nothing above there is additional support required beams wise. Also similar to the above, there is an existing stone base balcony on the right side (65cm above the garden at the tallest but less than 30cm above the garden at the shortest), we want to extend as above but it would now also sit in front of the 2 windows area. SEE attached diagram and photo of the proposals. Would the above 2 changes be ok under PD or planning required? Since they are both basically extending the current windows and balcony we are not sure and not getting a solid answer! CHEERS for the help, DD
