Seinäeristys

Seinäeristys refers to the thermal insulation of walls in buildings. Its primary purpose is to reduce heat transfer between the interior and exterior of a structure, thereby improving energy efficiency and occupant comfort. Proper wall insulation helps maintain a stable indoor temperature, reducing the need for excessive heating in winter and cooling in summer. This leads to lower energy consumption and reduced utility bills.

There are various materials used for seinäeristys, each with its own properties and applications. Common insulation materials include fiberglass, mineral wool, cellulose, foam boards, and spray foam. The choice of material often depends on factors such as cost, R-value (a measure of thermal resistance), moisture resistance, fire retardancy, and environmental impact.

The installation process for seinäeristys can vary. Insulation can be installed during the construction of new buildings or retrofitted into existing structures. For new constructions, insulation is typically placed within the wall cavities before the interior and exterior finishes are applied. Retrofitting may involve blowing insulation into existing wall cavities or applying exterior insulation systems.

Beyond thermal performance, seinäeristys can also contribute to soundproofing, reducing noise transmission between rooms or from the outside. It also plays a role in preventing condensation within wall structures, which can lead to mold growth and structural damage. Effective seinäeristys is a key component of sustainable building design, contributing to a healthier and more environmentally responsible built environment.
