If the heart of an Arolla building is the client, then CLT is its soul.
CLT, or Cross Laminated Timber, is a solid wood building element composed of at least three layers of sawn timber, glued together at a 90° angle to one another (i.e., crosswise). CLT uses formaldehyde-free glue that contains no residual toxins and is at the same time open to diffusion, so that the material has a moisture-regulating effect and thus ensures a comfortable indoor climate.
Health Benefits of Wood as a Building Material: Why a Wooden House is Good for Your Health.
Wood offers ecological advantages and numerous positive effects on our health. In today’s fast-paced world, many people long for a home that is not only beautiful but also promotes well-being. A wooden house combines these qualities, creating living spaces that have a positive impact on both body and mind.
Stress Reduction Through Wood
Studies confirm that using wood indoors can lower stress levels. Thanks to the so-called “biophilic effect,” wood, as a natural material, conveys a sense of peace and security. Researchers have observed a reduction in cortisol levels—the hormone released during stress—in environments where wood is used. This fosters a more relaxed atmosphere and contributes to overall mental well-being.
Better Air Quality
Wood has the ability to regulate humidity levels in a room. As a hygroscopic material, it can absorb moisture and release it when needed. This not only creates a pleasant indoor climate but also prevents mold growth and reduces airborne allergens. In a wooden house, you quite literally breathe healthier air.
Warmth and Comfort
Wood radiates natural warmth, contributing to a cozy living atmosphere. Due to its low thermal conductivity, wood feels warmer compared to other materials like concrete or steel. This natural insulation ensures a comfortable indoor climate while reducing energy consumption—beneficial for both the environment and your health.
Improved Sleep Quality
Another advantage of wooden houses is their positive effect on sleep quality. Research shows that rooms with wood maintain a more stable temperature, which positively impacts sleep. People who sleep in wooden rooms report more restful sleep and a lower heart rate—thanks to a balanced indoor climate and natural wood surfaces.
Acoustic Comfort
Wood has excellent acoustic properties, absorbing sound and contributing to a quieter home environment. This means less noise and fewer disturbances in your living space. A quiet setting enhances concentration, relaxation, and overall well-being.
Boosting the Immune System
Interestingly, wood also has a positive effect on indoor microorganisms. Studies show that wooden surfaces support a healthier and more diverse microbial community compared to synthetic materials. This can strengthen the immune system and reduce the risk of allergies.
