Anatomy of Thermal Efficiency


In order to maintain a very low level of heat loss we form a near unbroken barrier or envelope of  insulation around the building. Insulation is laid at ground floor level, applied to or set within the external walls and installed at roof level. We also apply insulation between floors and within internal partitions. Below is one of the typical sections from our detailed drawings. Our detailed drawings show sections through the building at different points to show detailed elements of the structure. The details are accompanied by notes which specify the materials, dimensions and other relevant information for both building control and contractors. 

  In the following posts we will give an overview of some of the main areas of importance with regard to providing solutions for whole house insulation, and also highlight the materials and techniques we will be employing to achieve a high standard of thermal efficiency.     

With foul drains pre-laid the internal walls are built up to floor level. 

A sand blinding layer is laid over the level fill of compressed hardcore.

With the damp proof membrane laid the ground floor insulation is cut and fitted to suit.

Another protective layer of  D.P.M is laid before the floor slab is poured and leveled.

With the slab now dry, work begins on the inner block skin.

Work continues on the ground floor block partitioning.

All joints between the thick slabs of insulation are taped and sealed. 

The build climbs towards the first floor.
