Tog ratings are the most important factor for many customers who are looking to purchase an insulating underlay. A higher tog rating means that the underlay will do a better job at keeping a room warm.
An underlay with a high tog rating can make a huge difference to a cold concrete subfloor or draughty floorboards. Not only will it prevent warm air escaping – it will also act as a barrier to cold air trying to get in.
Best Carpet Underlay for Insulation
Carpet underlays can be thicker than those used with laminate flooring, so they have a higher tog rating because they are naturally more insulating.
Tredaire Dreamwalk Underlay – 3.13 Tog Rating
The Tredaire Dreamwalk is the number one underlay for insulation. It’s a luxury feeling product with a very high tog rating of 3.13.
As well as keeping your home that little bit warmer, the Dreamwalk also has great sound insulation.
The Tredaire Dreamwalk has a medium density so we recommend it isn’t used in high traffic areas such as the stairs, landing and hallway.
Cloud 9 Cummulus – 3.1 Tog Rating
The Cloud 9 Cummulus is another luxury underlay with a high tog rating of 3.1.
This means it will do a fantastic job of keeping your home nice and cosy – and keeping your heating bills down!
Like the Dreamwalk, the Cloud 9 Cummulus should only be used in rooms like the bedroom and living room.
Thick 12mm Carpet Underlay -2.96 Tog Rating
A cheaper alternative to the luxury products is our own brand 12mm Thick Underlay.
Although not quite as insulating, it will still make a huge difference.
Because it is so thick, it feels heavenly underfoot so it’s perfect for relaxation rooms like the bedroom and living room. However this means that it isn’t suitable for the stairs and hallway.
Best Insulating Underlay for Laminate or Wood Flooring
Products suitable for laminate or wood flooring need be much thinner so they have a lower tog rating. They also need to be moisture resistant to increase the lifespan of your flooring.
Super Gold Laminate Underlay – 0.9 Tog Rating
Super Gold is the best insulating laminate underlay. It is the thickest product (5mm) you can use so it also has the highest tog rating.
As well as being insulating it also features a plastic vapour barrier which protects against humidity and it has a noise reduction rating of 22db.
Because the Super Gold is designed to be insulating, it is not recommended for use with underfloor heating.
3mm Laminate Underlay for Underfloor Heating – 0.45 Tog
The 3mm Laminate has a lower tog rating which means it’s a suitable underlay for underfloor heating.
Because it is only 3mm thick, it will allow the heat from under the floor to come into the room.
It also has a built-in damp proof membrane and a noise reduction rating of 19db.
Does Underlay even work as heat or floor insulation?
A good quality, insulating underlay will act as a high-quality thermal barrier. Especially when used over a concrete floor or draughty floorboards.
But it isn’t the only factor when choosing the right product for your home or building.
Things like thickness, density, noise reduction and the room it’s going to be used in are also very important.

Why is insulation in the home so important?
The biggest benefit of insulating your home is the money it saves.
You’ll find that with good quality insulation, you don’t need to use your heating as much. By being able to turn on your heating later in the Autumn and turning it off earlier in the Spring, you’ll save weeks’ worth of energy bills.
Not only is it great for the wallet, it’s great for the environment too!

Tog Rating – what does it mean?
Tog stands for ‘Thermal Overall Grade’ which is a unit of measurement used to calculate the thermal insulation of a product.
The higher the tog rating, the higher the level of thermal insulation provided by a product.
You will mainly see tog ratings given to things like duvets, sleeping bags and sometimes coats but the principle is the same with underlay.
An underlay with a high tog rating, like the Treadaire Dreamwalk will help to keep a room much warmer.
