Paroc® Protection

Paroc Protection

PAROC® PROTECTION is our concept for Nordic-designed stone wool, a material that offers superior protection from fire and moisture. A home protected with PAROC® Stone wool insulation gives you increased security against moisture. Stone wool does not absorb water well and due to its high steam permeability, it dries quickly if exposed to water. PAROC® Stone wool insulation is also non-combustible, placing it in the Euro Class A1 category, the best fire safety class available.

When there’s a fire, time is of the essence. Time to rescue people and time to save material goods. Time to limit the spread of the fire. When choosing what insulation you need, consider the following facts:

Stone wool is made of stone, which neither burns nor ignites. Stone wool insulation therefore does not contribute to the spread of fire. Instead, the material protects against fire. When it burns, stone wool, in some designs, has the ability to withstand the fire for a full four hours before the material is affected. The high heat resistance of stone wool makes it the obvious choice in projects where fire safety is important. The choice also affects a building's insurance premium.

PAROC Stone wool is incombustible and therefore classified in Euro class A1. It can be used in all structures, from simple partition walls via the polished facade to attics or low-pitch roofs. Stone wool counteracts the spread of a possible fire.

A partition wall with normal plaster boards on each side of the studs and 95 mm thick slabs of stone wool can withstand a fire for 60 minutes. To meet corresponding requirements with another type of insulation would require double drywall boards, with increased costs as a result.


Paroc Protection against waterStone against moisture

All buildings are exposed to moisture. It enters in places it should not and creates unseen problem. It is a well known truth that when moisture stays in a building’s structure, it can be a breeding ground for both mould and unpleasant odours – which directly affects the health and comfort of those occupying the premises

Equally well known is that moisture is the main cause of damage to building materials and structures — something that often jeopardizes both economy and function.

When you build, the choice of insulation is therefore crucial. You have two choices: take a risk and use an insulation material that traps moisture, or stay dry from the start. Stone wool has high water vapour transmission. This means that moisture passes through the stone wool if the heating is on. And if the stone wool is exposed to moisture, its dries out quickly. Stone wool also retains its heat, noise and fire insulating properties even after it has been exposed to moisture and then allowed to dry.

It is important with rendered facades on stud frames that the details and connections are made properly. Studies made by SP Technical Research Institute of Sweden show that stone wool is more forgiving and offers more safety than other types of insulation. When you’re on a budget, stone wool is an easy way to build. It helps you avoid future risks and costs for your rendered facades.
