Harmful-substance barriers

Kiilto is introducing new options and alternative products for sealing off harmful substances. Our R&D activities are based on strong chemistry expertise and the use of reliable development processes. Kiilto has long experience of barriers in the chemical industry. Our product R&D is based on industry expertise, and partly on benefiting from product formulae and user experiences in industry and construction.

Design plays a key role in the selection of barriers against harmful substances. Sealing repairs and, for example, alterations and measures to improve indoor air, should be designed carefully and individually. This is best left to an expert in every case. 

We provide designers with the most precise technical information possible, as well as product instructions. These enable comparison and choices based on the special features of a site. In addition, our conceptual detail drawings can be used when planning sealing repairs. The designer should always ensure that these are suitable for the location in question. You can download detail drawings, product cards and product information from the document bank folder: Sealing of structures

Indoor air info for designers

We provide more details on sealing repairs, indoor air design and the related products at our Indoor air events for designers. At these half-day briefings, we describe Kiilto's services and products for indoor air design. We also tell designers where to find important information and documents, and how to use them. 

Afterwards, you will know more about Kiilto's construction product options for ensuring high indoor air quality, and Kiilto's construction product features from the design perspective. We also aim to hold a joint discussion on indoor air issues, providing information and tools for solving problems and smoother design. Details on our forthcoming info sessions.

We have begun tailored training sessions for contractors and other customers who need information on how to use our products. At these product training events, we present a range of useful information and focus on installation techniques related to product use. See our Training page for details.
