About us<\/strong><\/h2><\/div>

We are a Czech company<\/b> founded in November 2017. Our establishment was inspired by the extensive experience of one of our colleagues, who previously worked in the production of fire doors. We leveraged this knowledge in the development of innovative passive fire protection elements<\/b>, leading to the creation of our own type of fire-resistant closure<\/b>, which enables natural ventilation in building structures.<\/b><\/p>\n

This was followed by a long development process, during which we conducted a series of demanding fire resistance tests. The result is a certified product<\/b> that fully complies with current legislation and meets all fire protection requirements for buildings.<\/b><\/p>\n<\/div><\/div><\/div>

We specialize in manufacturing and selling our own passive fire protection elements: fire-rated ventilation grids.<\/p>\n

The construction of our fire-rated ventilation grids is classified as a fire barrier and is suitable for installation in all civil, public, and industrial buildings. The fire resistance of all types of our fire-rated ventilation grids is tested according to the latest applicable testing standards at the state-authorised testing facility Pavus a.s. Czech Republic. Certificate for all the types of fire-rated ventilation grids has been issued by Technical and Test Institute for Construction, Prague, SOE.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

Product description<\/b><\/h2><\/div><\/div><\/div>

The complete product consists of two main parts. The first part consists of a doublesided fire-rated ventilation grid of the LKS type, preventing the spread of fire. This grid is installed into the fire partition wall into a pre-prepared mounting opening. The second part of the product consists of two pieces of exposed covers for the mounting opening of the LKL type, intended to cover the mounting opening on both sides of the fire partition wall. The installation procedure of the LKS and LKL type products is governed by the manufacturer’s issued Installation Manual.<\/p>\n

Fire protection grid of the LKS type ensure a continuous supply and exhaust of air in solid and light vertical building structures without the need for connection to subsequent ventilation ducts. In the event of a fire, expanding horizontal intumescent slats are activated. As these slats expand, the LKS grid is sealed, preventing the spread of flames and toxic gases.<\/p>\n

The LKS grid is not classified as smoke-proof. The fire resistance for all types of fire protection ventilation grids are declared as E90\/EI15-EI90\/EW90.<\/p>\n

Exposed LKL covers are offered in a standard light grey color. Upon request, LKL covers can be painted in any color from the RAL color spectrum. Each LKL cover has a label indicating its fire resistance rating and production number.<\/p>\n<\/div><\/div><\/div>
