Roof insulation is one of the key elements of heat preservation in the house. Due to an improperly insulated roof, up to 20-30% of the warm air can escape from the house. One of the reasons is the wrong thickness or the wrong position of the insulating material. What should be remembered when warming the roof? Check out the tips that will prevent the most common mistakes made when insulating the roof.
1. How to insulate the roof? High-quality materials
When building a house, we instinctively try to limit the budget for different elements. However, it is not always worth saving. Roof insulation is one of the most important components of heat preservation in the house. When investing in roof insulation, first of all, the quality and type of materials to be purchased should be taken into account. Responsibility for determining the compliance of the selected materials with the technical parameters. What should you pay attention to when choosing insulation products?
• thermal insulation level
• thickness
• Fire resistance
• weight.
2. Mineral wool for roof insulation.
The most popular material used for roof insulation is mineral wool. Among other things, it is characterized by:
• high ability to absorb sounds
• Water resistance
• vapor permeability
• very high fire resistance (protects wood in case of fire)
• low thermal conductivity.
However, you should not skimp on this material. Before choosing a product, familiarize yourself with its properties and decide which one will meet your expectations:
• glass wool – can withstand temperatures up to 600-700 °C.
• mineral wool – can withstand temperatures up to 1000 ° C and does not react to fire. Thus, this product reduces the risk of fire.
In addition to mineral wool, polyurethane foam and polystyrene are also popular. These products have similar properties and are often chosen because of the lower price. You can make a purchase only after the thermal insulation materials have been carefully selected for your own attic. Of course, it's worth looking at prices so as not to overpay, but when choosing, it's best to pay attention primarily to the properties and quality of the material.
3. Use foil with high vapor permeability.
This type of film should be placed under the roofing, i.e. before laying a layer of mineral wool. This foil should be nailed to the rafters in thin strips to properly tighten it.
4. Correct insulation thickness
The thickness of the insulation is also of great importance. Too thin a layer will be ineffective, and the warming effect will be unsatisfactory. It is assumed that the minimum thickness of the roof insulation is 20 cm. Two layers are usually laid with a total thickness of 25-30 cm.
It is also worth paying attention to the correct cut. Each board should be wider than the distance between our rafters by about 2-3 cm. This will prevent it from settling or forming cracks in the insulation layer. On the other hand, if mineral wool is not placed in a solid and compact structure, thermal gap bridges will begin to form. Heat escapes through them when we don't insulate the joint between the roof structure and the window frame well enough. They can occur when the walls are poorly insulated. This leads to dampening of the insulation layer and deterioration of thermal insulation. In turn, if the stuffing is too dense and durable, the ventilation gap will be significantly reduced. It can also push out the original coating foil, which will affect subsequent layers. Players who value quality and generosity from the start are turning to 20Bet more often.
