Glue Lam Technology. Laminated timbers are put to their most innovative use. The energy source and the structure are “Sustainable” and “Green” - the latest positive trend in home-building.Glue

These logs contain resin and a sea crystal salt. When the log becomes heated the resin changes state from solid to liquid. This state change requires energy in the form of heat. So the suns energy not only warms the wooden beams, but is absorbed by the resin. The liquid resin coalesces with the crystals and so does not seep out of the timber.

At night the log cools and the resin changes  back to solid and as it does so it releases the heat associated with the change of state.

In effect the log is a heat storage module.

These logs will be used for the ceiling of the ground floor, thus forming the floors of the South facing rooms of the upper floor.

This is of course another form of adding thermal mass to the house, but in this case using the 'latent heat of state change' to enhance the performance.
