Help!! Karndean fitting issues upstairs

What i mean is the system isn't part of the original subfloor, it's been installed retrospectively, which puts the hot pipes very close to the floor covering, it seems that the people who supply and fit these systems, do not give the customers any information about temperatures,so understandably, when they are told not to go above 27° ,they will look at the thermostat which says 20° ,not realising that to get the air temperature up to 20°, which is the temperature the thermostat is showing, the pipes will actually get to temperatures above 30°

 

Most of the people that install these heating systems don’t give a damn about the floor covering. They just wanna get the system in and get paid, preferably before the floors even installed. I wonder how many ask the customer what floor covering they plan to use before

Hi guys me again …. The other concern we have is the noise transfer as sounds like elephants are living upstairs when walking about on the karndean and boomy in sections. If we have UFH what should we have between that and the karndean? Read about Ragupol but not sure with the UFH? o think it needs ripping up so want to ensure we get it right and make sure we

 

You can thank your builders for that. You need a concrete subfloor or some heafty sound proofing below the subfloor/above the ground floor ceiling

Is there anything we can do now? As obviously can't install concrete at this point

 

sorry predictive text! I meant “can’t”

 

Not really. Most of our houses are not designed/built well enough to have hard floors installed. Everyone carpets the bedrooms so it’s not normally noticed. Most of the acoustic matts or underlays are designed to help reduce the footfall noise or impact. Around 20 db or the equivalent of a whisper. They won’t help stop noise transfer from your floor boards and joists that are below the matting

Hello all I have read about jumpax and regupol for UFH? The fitter has said it is not right and will take up and replace so thinking of having something like this installed?? Any advice welcome thanks

 

Unfortunately they won't work, your floor temperature is too high, i'd say the only thing that might work, but not guaranteed, is a thick screed to encase the pipes, the pipes should then heat the screed, giving a bigger heated surface area to bring the air up to the required temperature, but at an overall lower floor temperature, like i said, this is not guaranteed and something you should discuss with a heating engineer,as this is just what i think and i could be wrong, but i can pretty much guarantee that jumpax won't work on your system

 

Hi have found this online and it says:-

The Regupol 4515 Eco 4.5mm is a high performance impact noise reduction matting, which can be laid directly beneath carpet, luxury vinyl and laminate flooring types (alongside an underlay where applicable).

• Regupol® 4515 Eco soundproof underlay been independently tested by a UKAS accredited laboratory to show compliance with the new building regulations in accordance with Approved Document E 2003.
• Standard thickness 3mm & 4.5mm.
• Offers long term performance without collapse or “bottoming” out under highpoint loads.
• Resistant to ageing and deformation.
• Quick and easy to install. Simply bond to the subfloor beneath the final floor finish.
• Reduces construction heights.
• High quality and exact material thickness guaranteed.
• Suitable for use with under floor heating.
• Very comfortable under foot.
• Zero GWP (Global Warming Potential) and Zero ODP (Ozone Depletion Potential).

would this not work? As says UFH compatible also?

 

The product may be compatible, but the karndean isn't, once the karndean gets too hot, it will expand and distort, it will either lift on its own or take whatever it's stuck to,with it

 

Hiya, So we shouldn’t actually have karndean with UFH? As it is advertised as being suitable, and they have a high temperature adhesive for use with UFH?… sorry for all the questions just trying to work out how we proceed

 

It's suitable for most heating systems, but your system puts the hot pipes too close to the karndean, like i said, a thick screed might work, but you could always ask karndean how they would recommend laying it over your system,worth giving them a ring and see what they say

 

Cheers thank you

 

Update - Spoken to Karndean and they have said it is fine to fit provided temp does not exceed 27 degrees in the floor. They have recommended a floating floor for sound instead of the 6mm chipboard. Have said they do verislay but maybe better alternative as verislay has foil backing…. Any suggested floating floor alternatives? They said regapol will invalidate warranty

 

Have you measured your floor temperature?

 

Just get the temp down. The plumber should be able to adjust the flow

You can use Jumpax without the foil
