Protecting wood exterior infrastructures above ground in Spain. The importance of protection by design in the performance
2019 - IRG/WP 19-40874
Across Spain is very common to find wood exterior infrastructures build mainly in sawn and glue-laminated wood. Most of these exterior wood infrastructures use softwood wood species such as: fir, spruce, larch and pine. In Spain exterior wood infrastructures, became more and more popular since nineties, when sawn and glue-laminated wood were utilized for building exterior wood infrastructures in o...

Performance of wood exterior structures above ground in Spain. Performance and durability of a shelter of spruce in a shopping centre after 20 years
2022 - IRG/WP 22-20680
Across Europe is very common to find wood exterior structures mainly build in sawn and glue-laminated wood. Most of these exterior wood structures use softwood wood species such as: fir, spruce, pine or douglas. In Spain exterior wood structures, became more and more popular since nineties, when sawn and glue-laminated wood were utilized for building exterior wood structures in overall Spain. In m...

Significance of the thermal design and the sorption isotherm shape in hygroscopic wood moisture dynamics and service life
2022 - IRG/WP 22-20682
Moisture dynamics are considered important for predicting the service performance of wood in exterior applications. Above a critical moisture content, water acts a softener on the structural polymer matrix of the wood cell wall, enabling the necessary diffusion of molecular species involved in the fungal degradation mechanism of wood. Water may enter solid wood in either liquid form or in vapor fo...

Joints design considerations in indoor high humidity conditions
2022 - IRG/WP 22-40950
In recent years, a number of cases of degradation by wood destroying fungi have been detected in covered timber structures such as pools, wineries, bathrooms, etc. – in fact, any building where indoor air may reach high humidity values during certain periods of time.
The origin of this kind of decay was not related to water leaks, but to the condensation of the water vapor over the steel connec...

Moisture performance of wooden shingles tested on the Golobar cable yarding
2023 - IRG/WP 23-20704
Wood is a traditional roofing material in Europe and other parts of the world. In the 17th century, wooden roofing was generally used on more important buildings, but today it is mainly used on huts and houses in the Alpine regions. As wooden roofing is expensive, we investigated the possibility of extending the service life of the roofing through material selection and details. The roof of the Go...
