Fire- resistant frames, doors and windows

ALSAL IS A MANUFACTURER OF MANY DIFFERENT TYPES OF FIRE- RESISTANT EXTERNAL AND INTERNAL FRAMES, DOORS AND WINDOWS OF EI FIRE RESISTANCE. FOR MANUFACTURING OF THESE ELEMENTS WE USE – BOTH FOR EXTERNAL AND INTERNAL ELEMENTS – SPECIAL INSULATED PROFILES WITH AN APPROPRIATE NUMBER OF SPECIAL INSERTS THAT DECIDE ABOUT FIRE-RESISTANCE OF ALUMINIUM ELEMENTS AS PER THE GUIDELINES OF THE PRODUCT DOCUMENTS.

Elements of EI fire resistance are manufactured and assembled strictly as per technical approvals and guidelines of the Building Research Institute for these elements.

The maximum allowed sizes of fire resistance elements, construction divisions, type and thickness of fillings, etc. are strictly defined by relevant documents (technical approvals, etc.).

In its offer, ALSAL has different types of frames, doors and windows, depending on the criteria of product classification and the function that the product is to fulfil. Each element of EI fire resistance is smoke-tight.

  4. Watertightness
  5. Impact resistance
  6. Acoustic properties
  7. Heat permeability
  8. Strength requirements
  9. Resistance to weather influences
  10. Mechanical durability of external doors
