Carpet Less Than 1 5 Tog

Please note that the insulating effect of underlay and carpet are to some extent cumulative.

Carpet less than 1 5 tog.

0 n narrow loom widths usually woven only are 0 69m 0 9m l 0m 2 0m. It makes sense to take care in choosing carpet and underlay that will work well with the underfloor heating. As nzs 1385 specifies the following commercial tolerances for. We can offer the following information which has been taken from test reports in accordance with bs 4745 two plate test from bttg shirley.

Our 80 wool 20 nylon carpets have a tog value somewhere between 1 4 and 2 3. This is not the case. We would suggest a target tog should be 0 8 or less. If you are wanting an underlay for hard flooring then a tog rating of less than 0 4 is ideal.

Tog values typical brintons 80 wool 20 nylon carpets have a tog value 1 4 and 2 3. Figures between 0 80 and 1 50 tog have been quoted by manufacturers foam underlays generally have a lower tog rating than felts. If you are looking for an underlay for underfloor heating in combination with a carpet this is quite a specialist requirement. In conjunction with the underfloor heating manufacturers association the carpet foundation carried out a research project.

However research conducted by bsria in bracknell and funded by the carpet foundation in conjunction with the underfloor heating manufacturers association uhma has proved conclusively that any carpet can be used with an underfloor heating system without impairing the performance of the system. The previous industry standard has been to advise that the carpet and underlay should not exceed a tog rating of 1 5. The best carpets to use with underfloor heating are those with tog ratings of less than 1 5. Quality manufacturers will have technical information on their products available to customers.

This showed that a carpet underlay with a combined thermal resistance of less than 2 5 togs allows underfloor systems to operate efficiently. The combined value of the carpet and underlay should not exceed 2 5 tog and preferably less than 1 5 for heat pump systems. Suppliers however have stated that carpet must have a thermal resistance of no more than 1 5 1 7 tog. As well as the tog rating of the carpet you must also consider the tog rating of the underlay.

This theoretically means that shaw carpets in the 4 5 rating would be ideal for areas where there is going to be a lot of traffic like hallways and stairs whilst a rating of less than 2 5 is going to be better in an area that isn t used so. Tolerances for the dimensions of tufted and woven carpet.
