Firstly, the facts, the laws of thermodynamics say that the denser material is the quicker it will transfer heat. The thinner that material is the quicker that heat will then be transferred into the air from it. This means that a dense thin material will transmit heat into a room much more quickly than a thick material which is less densely packed. This is why thick aerated materials are often used for insulation to keep heat in. So, how is this applied to underfloor heating.
A wooden floor, even one intended for underfloor heating, is much more than just a method for transmuting heat. Oak flooring needs to be aesthetically pleasing, to wear well underfoot and to be competitively priced. When we factor this in it builds a picture what we need for the best underfloor heating.
The underside of oak flooring made specifically to work with underfloor heating needs to be durable to withstand the fluctuations in temperature, so plywood is used. Plywood benefits from being strong, hardwearing and dense because of its layered, glued make up. This density lends itself well to heat exchange but at Oak Floors Online we have gone one step further introducing Thruflow technology. Thruflow uses pre-drilled plywood as the base for our engineered oak flooring. This maintains the structural integrity of the boards while vastly improving their ability to transmit the heat into your room.
