Thermal insulation of roofs

The answer to the question of why deal with thermal insulation of the roof at all is very simple. Throughout the year, the roofs are exposed to various weather conditions, which places high demands on the building's ability to retain or, on the contrary, emit heat. With a quality thermally insulated roof, you can be sure that the building will be much less energy intensive. In short, it will not be necessary to heat as much, which will have a positive effect on the accounts of the construction user. And this principle works the other way around, in high heat, proper thermal insulation prevents heat from plaguing everyone inside the building so much.

As with any other insulation, care must be taken to ensure its precise design. Even small imperfections can result in leaks and the insulation will not perform its function 100% and minimize heat loss. It is therefore necessary to pay attention to details and at the same time the thickness of the insulating material. Some thermal insulation will also work with acoustic insulation, but this is always necessary to verify in the product label before purchase.

Today, you will find on the market thermal insulation suitable for use with all possible types of roofs - sloping (under rafters and above rafters) and flat ones.

Types of thermal insulation materials for roofs

Important parameters according to which you will choose roof thermal insulation are definitely load-bearing capacity, water absorption, the insulation properties themselves, fire resistance of the material and you may also be interested in whether the production of the insulation is ecological and does not burden the environment too much.

In the offer you will find several types of materials from which thermal insulation for roofs is made.

A popular material is polyurethane foam. It is highlighted especially for its excellent thermal insulation properties even at a relatively small thickness. It is great for both low-energy and passive houses. The installation of foam insulation is relatively easy and in addition to the thickness, it is necessary to think about the length of the foam block in order to fit well under the roof. However, polyurethane foam is easy to work with, so it can be adjusted relatively quickly as needed.

Thermal insulation with mineral wool, under the roof, is also popular. The advantage of this type of insulation is a favorable price, but it may not be a suitable solution when the attic is to be inhabited. This type of insulation is laid inside the interior. Its advantages include the fact that it is resistant to various fungi, insects and molds. Another type of popular roof insulation is blown ones. These quickly reach all cavities and, in addition, no waste is formed.

In the case of flat roof insulation, it is good to answer the question whether to apply an insulating or waterproofing layer directly to the roofing or whether to first remove this covering and then apply the insulation or waterproofing. Popular insulation layers include waterproofing foils, which begin to extrude conventional asphalt strips.
