Moisture is one of the biggest threats to timber buildings. If left unnoticed, it can lead to rot, mould, or even structural failure — putting your reputation, schedule, and bottom line at risk.
Tector helps you catch issues early by measuring safe moisture levels in walls and roofs. Our wireless moisture system keeps track of key risk zones so you can act before damage sets in.
Whether you’re working with CLT, timber frame, or prefabricated elements, we give you the confidence that your structure stays dry, healthy, and fit for the future.
Tector combines smart sensors with cloud-based software for effortless tracking of moisture and humidity.
Here’s how it works:
The result? Faster decisions, fewer risks, and more durable timber structures.
Designed for efficiency on site, Tector sensors are:
Once placed, your wood sensor network begins collecting real-time moisture data and keeps going for up to 25 years with no maintenance needed.
Our system delivers serious performance in a simple package:
Get an expert consultation, and follow our guidelines to determine where to place and mount sensors, and at what density.
For CLT flat roofs, we recommend installing 1 sensor per 10 to 25 m², depending on the roof's risk level and the value of the interior.
The sensor is easily installed from below, with insulated pins measuring moisture in the top panel of the CLT.
Water ingress often affects this top panel, which can lead to rot and compromise the roof's structural integrity.
Each prefabricated timber roof cassette requires 1 sensor to monitor moisture, especially during installation.
Built-in moisture can lead to mould growth, and even a small hole or unsealed area in the top membrane can damage the entire cassette.
Roofs with green or solar panels increase the risk of moisture-related problems and the cost of repairs.
For prefabricated facades, one sensor is required every four elements in critical areas, such as top and bottom corners near the foundation.
Water ingress often occurs during construction from roof runoff or when membranes remain open. External factors like balconies or high-altitude pressure also contribute to moisture risks.
For timber frame roofs, sensors should be placed in risk-prone areas such as around dormers, chimneys, and ridges.
They can detect poor ventilation, which can lead to excessive moisture build-up over time and result in mould growth.
Leakages or condensation around penetrations can also be caught early, preventing long-term damage to the structure.
Sensors should be placed in high-risk areas where moisture can enter, such as from the foundation or roof leaks.
Poorly sealed penetrations, like windows and ventilation, can lead to moisture build-up.
On average, one sensor is needed for every 40 m², with placement varying based on the building’s risk profile.
Sensors are installed under windows or near the foundation, ensuring critical areas are covered.
During construction, walls are exposed to rain, and manual moisture checks can be time-consuming.
Moisture also enters through the foundation, roof leaks, or improperly sealed penetrations such as windows or ventilation points.
One sensor is recommended every 50 m² during construction.
Slabs are particularly vulnerable to rain exposure, requiring careful monitoring to ensure moisture levels remain under control. Trapped moisture from in-situ concrete or improper closure during high moisture levels is a common issue.
Tector's technology promotes environmentally responsible practices, aligning with global sustainability goals and regulatory requirements, and adds value for DGNB, LEED, Eco label and BREEAM certifications.
By using Tector's sensors, we eliminated the need for random sampling, as the sensors provided continuous, accurate data. This allowed us to streamline quality assurance and make informed decisions on-site.
