Top floor ceiling insulation

The world nowadays....under the current energy saving regulations have a sufficient thermal insulation of top floor ceiling provide homeowners. If an attic is not to be removed, appropriate insulation can be retrofitted to the existing ceiling applied to be one too. This is so important because the top floor ceiling in an unheated attic as the separation between the warm air from the rooms below and the cold outside air to function. In order to avoid losses, an efficient insulation can be applied that will saves expensive heating!

To have a blanket to a non-upgraded attic insulation in new construction must have a thickness of 260 mm and a U-value of 0.17 to 0.2 [W (m² K)]. In the old building, the insulation 140 mm thick and have a U-value of 0.30 correspond to [W (m² K)]. This is usually on the packaging.

Greatly influences the quality of building insulation and therefore the energy saving is the thermal conductivity of the insulation material used. The lower the thermal conductivity, the greater the insulating capacity. Systems of the thermal conductivity of rock wool (WLG) 0035 prevent winter heat escaping through the roof up and make you stay cool in the summer, moreover stone wool is also not flammable and sound insulation.

As insulating material for non-developed, unheated attic is suitable, for example, rock wool insulation felt, offered as a compressed rolls. Such insulation is not usually accessible. If the attic is to be used as storage space then a recommends laying timbers in the thickness of the insulation material and a cover made of fibrous plaster, wood chip or wood-based panels. The insulating material between the timber is fitted with sealed joints. Following the expansion boards are placed on the squares - the insulation is now accessible.

Suitable alternative to mineral wool insulation felt and highly compressed insulation boards in question. Due to its high compressive strength reaches a position already laying floor slabs in a thickness from 13 mm to distribute the load. Such a floor may have already committed and are loaded with light objects. If the attic is used more intensively, the gypsum fiber panels recommend a thickness of 18 mm or 19 mm thick particle boards.
