Airtight sealing of window and door joints

Joints between window frames, doors and facades are notorious sources of air leaks, thermal bridges and moisture problems. Movement and tolerances in construction often create cracks and gaps here, causing draughts, energy loss and reduced sound insulation.

Depending on the location and finish, two suitable solutions are available: Liquid Rubber HBS200 and Liquid Rubber AB Sealant. Both products are elastic, vapour-proof, air- and watertight and provide reliable and durable sealing of window and door joints, tailored to the specific requirements of the indoor or outdoor situation.

Perfect sealing for complex building scenarios

The modern home must meet increasingly stringent requirements for quality, safety and economy.

With Liquid Rubber, you have an advanced liquid sealing system that fits seamlessly into the practice of professional construction. It forms a durable, elastic membrane that provides superior protection and increases processing efficiency.

With Liquid Rubber HBS200, you can seal all air seams around (adjustable) window frames immediately. Because Liquid Rubber HBS200 adheres to all substrates, everything can be sealed airtight in one application, including fixing anchors etc.

For applications on the inside of the building shell, the same can be achieved with our AB Sealant. This white coating can then be easily over-plastered or painted, without risk of the coating bleeding through.

Liquid Rubber HBS200

For outdoor applications is Liquid Rubber HBS200 ideally suited. This ready-to-use liquid coating adheres to virtually all substrates - from concrete to masonry and wood - and completely seals even complex shapes.

Liquid Rubber HBS200 can be easily applied with a brush or roller and, for larger projects, can also be sprayed with an airless pump. The result is a seamless, permanently elastic and water- and airtight seal that can withstand the harshest conditions.

AB Sealant

For indoor applications where the connection is later finished with painting or plastering, is Liquid Rubber AB Sealant the ideal choice. This white, water-based coating is specially developed for airtight interior finishes and does not cause bleeding or discolouration in finishing coats. AB Sealant is permanently elastic, easy to apply by brush, roller or spray, and perfectly paintable.
