Modern building envelopes are complex. They require that you consider insulation continuity and air tightness early in the design process.

When a building has good air tightness, it stops the outside cold from penetrating the building fabric, or depending on the direction of the pressure gradient, keeps the warm air in.

Different floors demand different insulation solutions. Intermediate floors have to be well insulated against noise between the floors. Ventilated floors act like a facade below the building, while ground slabs have high demands for moisture movement. A well-insulated floor structure creates a good sound environment and keeps you feet warm on cold winter days.

PAROC step sound insulation minimises structural borne (step sound) noise and improves living comfort in the building.

The easiest way to improve the step sound insulation of old timber floors is to remove all old floor material from the top of the bearing joists. Depending on the condition of the old insulation, it can be left intact or removed and replaced with PAROC eXtra.

In warm attics, the dimension of the joists limits the thickness of the insulation.

In many countries, simple log walls do not fulfill today’s energy efficiency demands without an additional insulation layer.

The insulation of a sitecore:item:Tree_Node_19B5DDD766E84B6694A1C8E0B31BC006pitched roof at rafter level (warm attic) enables maximum utilisation of roof space in both new and refurbished residential and non-residential buildings.

Regardless of the type or slope of the roof, it is the most important part of the building envelope contributing to heat loss and energy efficiency. When you reduce heat loss through your roof, you need less energy to heat your entire house.

Our top recommendation for a timber wall structure is what we call a Nordic Wall. A Nordic Wall achieves the desired U-value with a thinner structure compared to other timber structures.

Sawdust in old wall structures has fairly poor thermal insulation capability with extremely high ignitability. If you want to improve the thermal performance of the external wall more, replace sawdust insulation with PAROC stone wool.

A suspended or ventilated timber floor is detached from the ground with a ventilated subfloor space below. The structure of ventilated floors is very similar to wall construction.

A suspended or ventilated timber floor is detached from the ground with a ventilated subfloor space below. Old insulation used in ventilated floors usually settles over time, creating to a gap between the floor surface and insulation layer. Gaps between the floor joists and insulation allow cold air to easily spread under the floor surface, which cools down the whole floor surface.
