Linervent’s method seals leaks in ventilation ducts regardless of shape and size. The material is elastic and dampens sounds that can otherwise propagate easily in a ventilation system. Read more about the material here!
Sealing ventilation removes typical problems such as poor kitchen ventilation, non-compliance with government regulations, poor indoor climate, etc.
Linervent has an installer network which covers all of Sweden. Have a look at our installers or contact us to find an installer who can help you with your problem!
When the ducts leak, it is not just the air drag that becomes a problem, smells and sounds can also spread to unwanted spaces through the holes in the ventilation system. Many people know that poor ventilation is harmful to your health, but the problem is easily ignored if nothing is apparent in a short perspective. Unfortunately, far fewer people are aware that leaking ventilation also has a major impact on their economy.
In a non-air-tight system, compensating with increased fan speeds is required. Energy is consumed by oversized fans, filters, heaters, heat exchangers and so on. Compared to an air-proof system, more air is also drawn out of the house, which means that there are heavy heat losses, especially during the winter months. In many cases, a duct sealing effort may halve the property's heating costs.
We have made a video showing how much impact leaks have on the heat consumption. See the video below.
After contacting one of Linervent’s installers, a general review of your needs as a customer is made, drawings are submitted and a time is booked for a review of the property and ventilation ducts. If other efforts need to be made (such as fan replacements), the appropriate subcontractors are contacted. When the number of ducts, branches and the condition of them have been determined, an action plan and a schedule are made. The customer may also decide if there are other jobs that are to be performed in conjunction with the contract, such as a fan replacement, heat recovery etc. After this, Linervent’s installer provides a quotation.
The method is then performed in the following steps:
1. Inspection
2. Cleaning
3. Relining
4. Quality inspection
The ventilation ducts are inspected using a fiber optic camera. That way, you can judge the state of the ducts and understand its branches.
In case of heavy soiling, cleaning is done by brushing or washing. The choice of method depends on the material in the duct and the duct’s overall configuration.
A flexible, air tight and fireproof composite material is hardened in place in the ventilation duct. This means a sock of composite material is inflated inside the ventilation duct. The sock is then hardened under excess pressure. This allows the sock to adhere well and mimic the shape of the tube.
After the new composite pipe has hardened, an inspection of the ventilation duct is made to ensure that the sealing has gone according to plan. Inspection films are submitted to the customer. Other quality tests that can be added are pressure proofing and a new ventilation inspection (via partner company).
