How to Make Insulated blind area, which will reduce the cost of heating homes.

the importance of warming blind area around the house often undervalue. To protect the foundation from premature destruction few just take away the rain and melt water.

It is necessary prevent soil freezingBecause under the influence of low temperatures in the soil water freezes and begins to expand, which has a devastating effect on the foundation (Cracks are beginning to appear).

Insulated blind area helps to prevent this negative process.

In addition, it allows reduce heat loss and as a consequence, reduce home heating coststo 20%.

And given the constant rise in energy prices investment will pay off for sure.

Erection begins with insulated blind area digging trenches on the perimeter of the house.

In this case, the future blind area must be wider roof eaves at least 20-25 cm.

BUT otmostki depth depending on the soil type and thickness of the finishing layer should be at 30-40 cm.

Blind area must be done at a slant from the wall 1,5 - 10° depending on the finish.

Once the trench is dug it must be compacted and you can start making sealing cushion.

Along the perimeter of the excavated trench fall asleep oil sand pack 7-10 cm thick.

then comes gravel layer 10 cm thick and again oil sand pack 2-5 cm thick. Each layer should be thoroughly compacted.

Then, on the edge of the trench must be installed removable from the formwork boards or concrete curbs.

As a heater will use XPS (penoplex). To date it is the best option.

At next sand layer otmostki sheets laid one insulation layer (and can be in two layers, if the climate is harsh) and seams fill with foam.

Then do damping joints, installing planks on edge every 2-3 meters, and in all corners of the house across the blind area.

After that, to increase the strength of the concrete layer on penoplex reinforcing mesh laid on the pad and the concrete fill otmostku solution.
