About us
We are a young Czech company founded in November 2017. The idea behind establishing the company was to use our rich experience in the process of manufacturing fire doors. We have created our own type of a fire damper ensuring natural ventilation in the walls of buildings.
It was followed by a long development process with several fire resistance tests of the product structure. Our efforts resulted in a certified product that complies with applicable legislation and requirements related to the fire protection of buildings.
Likuhas company
We specialize in the manufacture and sale of our own design of passive fire protection elements – fireproof ventilation grilles.
The design of our fireproof ventilation grilles is classified as a fire damper and is suitable for placement in all civil, public and industrial buildings. Fire protection of all types of our fireproof ventilation grilles is tested according to the latest valid testing standards in the state-authorized testing laboratory Pavus, a.s.
The certificate for all types of fireproof ventilation grilles was issued by the Technical and Test Institute for Construction Prague, SOE.
Product description
The complete product consists of two basic parts. The first part consists of a doublesided LKS-type ventilation grille, preventing the spread of fire. This grille is installed in the fire-rated partition wall in a pre-prepared mounting hole. The second part of the product consists of two pieces of exposed LKL-type covers of the mounting hole, intended for decorative covering of the mounting hole from both sides of the fire-rated partition wall. The method of installation of the LKS-type product and the LKL-type product complies with the manufacturer’s installation instructions.
The LKS-type fireproof grilles provide permanent air inlet and outlet in rigid and light vertical building structures without connecting adjacent ventilation ducts. Horizontal intumescent plates expand in the event of a fire. The expansion closes the LKS-type ventilation grille and prevents the spread of fire and toxic gases.
The LKS-type grille is not classified as smokeproof.
The fire resistance values according to ČSN 73 0810 are declared as E90/EI15-EI90/EW90 for all types of fireproof ventilation grilles.
The LKL-type covers are offered in a light grey as standard. The LKL-type covers can be painted with RAL colours on request.
A label with marked fire resistance and serial number is placed on the LKL-type cover
