1. Wall Insulation1.1. Interior Insulation

Insulation with plasterboard mounted on studs

Mounting of the studs

Application of PUR

Installation of plasterboard

1. Wall Insulation1.1. Interior Insulation

Advantages:

Easy installation, no need for scaffolding

No problems of exterior emissions

Cost-effective method

Faster Heating (Wall has less thermal inertia)

Insulation with plasterboard mounted on studs

Inconveniences:

Having to clean the studs if the rails are installed first

Loss of space, if the studs are installed after

Low thermal inertia

Wall Insulation

Interior Finish with Ceramic Bricks

1. Wall Insulation1.2. Intermediary Insulatio

06/07/2006 7

Advantages:

Easy installation, no need for scaffolding

No problems of exterior emissions

Cost-effective method

Faster Heating (Wall has less thermal inertia)

Inconveniences:

Difficult treatment of thermal bridges, like wall-floor intersection

Medium Thermal Inertia

Standard solution in Spain, with approximately 25 million square meters every year.

1. Wall Insulation1.3. Exterior Insulation

06/07/2006 9

Advantages:

Excellent treatment of thermal bridges

Possibility of installing ventilated façades

Multiple options for exterior finish

Low possibility of interstitial condensations

Inconveniences:

Difficult application, need for scaffolding or cranes

More product loss and emissions into the environment

Parked cars may be stained my small dropplets

High dependence on weather conditions

2. Roof insulation2.2. Flat Roofs (Renovation of Roofs)

Advantages: - Sealing and insulation in one step- Buildings can be used „as usuall“ during the reconstruction- cost effective

Finished roof

2. Roof Insulation2.3. Inclined Roofs (Renovation of Roofs)

•Foam is applied over existing roof•Foam needs to be covered by a UV protective cover

06/07/2006 25

•Application of foam from the inside•The foam insulates, seals and holds the tiles in place
