Subfloor void cellar tray retrofit

The owner of this house asked us if we could help him reduce his energy costs, The house is 19th century country house with a large void beneath the ground floor, Cold air was entering the house through  air bricks beneath the floor, warm air was also escaping through the floors. We installed our patented system with 200 mm insulation from below using our cellar trays, installing insulation this way meant we did not have to take the floor up, saving time and importantly money for the client. The trays are easily altered using scissors or knife and fixed beneath the floor joists using a small compressor and powered staple gun with 40mm staples, obstructions  encountered were, pipes, wires, support walls and builders rubble ( from previouse jobs ) the job was finished on-time and to budget.

 

Here you can see just some of the obstructions to over come when insulating floors.
