Zolderisolatie En Ventilatie Gaan Hand In Hand.

They keep your house cooler in the summer, warmer in the winter and free from damage caused by moisture.

Why is that so important?

The main goal is to keep the temperature in the attic in summer and in winter equal to the temperature of the outside air.


the concern in the summer is heat. By building up extra heat under the roof terrace, your shingles can deteriorate much faster, so that life expectancy is sometimes halved. In addition, your cooling system will have to work harder to keep your home comfortable. For example, when the outside temperature is 90 ° in the summer, loft temperatures can easily reach 120 ° -150 °. This keeps your air conditioning system switched on for longer to keep the house cool, resulting in higher energy bills.


our biggest concern in the winter is moisture. Warm and humid attic air combined with cold outside temperatures leads to condensation, which can form on all cold wooden surfaces, metal nail heads, chimney surfaces, ventilation pipes and even in the insulation. If left wet for an extended period of time, this moisture causes wood rot, deterioration of the brick on the chimney surfaces and may eventually cause mold. In addition to moisture, heat loss also becomes a major problem in the winter, because wet insulation has a lower R value than dry insulation.

Where does all that heat come from?

The heat usually comes from two sources:

Inside the house –

The warm air is caused by conduction (the transfer of heat between two materials in contact with each other, caused by a temperature difference between the materials) or by convection (the transfer of heat by the circulation or movement of air).
Conduction usually occurs when the ceiling materials draw the heat from the air in a room and transfer it to the insulation and ultimately to the attic air. It requires no movement of air to take place and is usually a sign of insufficient insulation in the attic

Convection occurs when air escapes through small openings around lights, outlets, baseboards, or other openings in your walls or ceilings. This movement of air will flow through the wall cavities and find its way to the attic, and is usually a sign that air sealing is required.

Outside the house –

The attic space is heated by solar radiation (heat gain caused when materials are heated by the sun). Solar radiation can pass directly through your roof materials (also during the heating process) to your attic space and beyond.
