This gap serves as a service space where you can conceal cables, pipes, ventilation ducts and heat recovery units, whilst achieving a smooth, aesthetically pleasing ceiling regardless of what lies above it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In a typical flat in a block of flats, where the ceiling is uneven or pipes and beams are visible, a suspended ceiling made of plasterboard is the quickest and cheapest way to achieve an attractive finish. It does not require removing plaster, running cables on the surface or costly bricklaying work.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Key benefits at a glance:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>conceals the electrical, ventilation and heat recovery systems,<\/li>\n\n\n\n<li>levels out unevenness in the ceiling without chiselling or plastering,<\/li>\n\n\n\n<li>opens up possibilities for acoustic and thermal insulation,<\/li>\n\n\n\n<li>offers the possibility of decorative effects \u2013 LED lighting, recesses, alcoves,<\/li>\n\n\n\n<li>makes it easier to access the system during future repairs \u2013 without having to break open the walls,<\/li>\n\n\n\n<li>It enhances the visual appeal of the interior at a relatively low cost.<\/li>\n<\/ul>\n\n\n\n<h3 id=\"kiedy-warto-zainstalowac-sufit-podwieszony\" class=\"wp-block-heading\">When is it a good idea to install a suspended ceiling?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A suspended ceiling is particularly suitable if you have an old ceiling with unevenness of more than 2 cm, want to conceal central heating pipes, electrical wiring or ventilation ducts, are looking for better acoustics (in a block of flats or an office), or are planning to install recessed lighting \u2013 spotlights or LED strips.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, this isn\u2019t always worth it. If your room has a clear height of less than 230 cm, losing a further 8\u201312 cm might make too much of a difference in day-to-day life \u2013 in which case, consider an alternative, such as a stretch ceiling, which takes up less space.<\/p>\n\n\n\n<h3 id=\"sufit-podwieszony-a-sufit-napinany-co-wybrac\" class=\"wp-block-heading\"><strong>Suspended ceilings versus stretch ceilings \u2013 which should you choose?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">This question comes up in practically every renovation project. The short answer: if you\u2019re doing it yourself and don\u2019t need 3D effects, plasterboard wins out on price and availability of materials. A stretch ceiling is worth considering for very unusual shapes or mirror effects.<\/p>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table class=\"has-background has-fixed-layout\" style=\"background-color:#8dd2fc63\"><thead><tr><th><strong>Feature<\/strong><\/th><th><strong>Plasterboard ceiling<\/strong><\/th><th><strong>Stretch ceiling<\/strong><\/th><\/tr><\/thead><tbody><tr><td><strong>Cost of materials<\/strong><\/td><td>50\u201390 z\u0142\/m\u00b2<\/td><td>80\u2013200 z\u0142\/m\u00b2<\/td><\/tr><tr><td><strong>DIY assembly<\/strong><\/td><td>Yes, that\u2019s possible<\/td><td>No \u2013 it requires a specialist<\/td><\/tr><tr><td><strong>Shelf life<\/strong><\/td><td>Very high<\/td><td>High<\/td><\/tr><tr><td><strong>Moisture resistance<\/strong><\/td><td>It depends on the board (impregnated)<\/td><td>High<\/td><\/tr><tr><td><strong>Aesthetic possibilities<\/strong><\/td><td>Standard<\/td><td>Very large (3D shapes)<\/td><\/tr><tr><td><strong>Installation time<\/strong><\/td><td>1\u20132 days (DIY)<\/td><td>A few hours (the team)<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><em>Conclusion: for DIY projects and standard rooms, a plasterboard ceiling is unrivalled in terms of price, availability of materials and the ability to install it yourself.

A standard plasterboard ceiling construction will lower the ceiling by at least 7\u201310 cm (profile + board), and with noniusz hangers by as much as 20\u201330 cm if more services need to be concealed.<\/p>\n\n\n\n<h2 id=\"rodzaje-sufitow-podwieszanych-przeglad-systemow\" class=\"wp-block-heading\"><strong>Types of suspended ceilings \u2013 an overview of systems<\/strong><\/h2>\n\n\n\n<h3 id=\"sufit-podwieszony-z-plyt-gk-najpopularniejsze-rozwiazanie\" class=\"wp-block-heading\"><strong>A suspended ceiling made of plasterboard \u2013 the most popular solution<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A plasterboard system is by far the most common choice in Polish houses and flats. The principle is simple: a metal framework made of CD and UD profiles, suspended from hangers screwed to the ceiling, to which the plasterboards are fixed with screws every 150\u2013200 mm.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As part of our quality standard at the PK Complex shop, we offer genuine KNAUF system products \u2013 renowned for their accurately specified parameters, precise profile dimensions and comprehensive technical documentation. KNAUF materials are compatible with one another, which eliminates any surprises on site.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Advantages: low cost, suitable for DIY projects, easy to work with and cut, an excellent base for painting.<\/li>\n\n\n\n<li>Disadvantages: standard plasterboard cannot withstand damp (waterproof plasterboard is essential for bathrooms), and the joints need to be filled.<\/li>\n\n\n\n<li>Suitable for: living room, bedroom, hallway, office \u2013 virtually any dry room.<\/li>\n<\/ul>\n\n\n\n<h3 id=\"sufit-podwieszony-akustyczny-kiedy-potrzebujesz-wyciszenia\" class=\"wp-block-heading\"><strong>Acoustic suspended ceiling \u2013 when do you need soundproofing?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">There are two ways to improve the acoustics in a suspended ceiling \u2013 and it\u2019s worth combining them:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Filling the space between the ceiling and the plasterboard panels with mineral wool reduces the transmission of impact noise (footsteps, moving furniture) and airborne noise (conversations, the television). Even a layer of just 5\u201310 cm significantly improves comfort at no extra cost.<\/li>\n\n\n\n<li>Special perforated acoustic panels (e.g. Knauf Cleaneo) \u2013 absorb sound in a room and improve reverberation. Ideal for studies, children\u2019s bedrooms and recording studios.<\/li>\n<\/ol>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><em>With the ceiling structure already open, adding mineral wool is a low-cost measure that makes a big difference \u2013 don\u2019t skip this step if you have neighbours living above you.<\/em><\/p>\n<\/blockquote>\n\n\n\n<h3 id=\"sufit-podwieszony-krzywoliniowy-i-wielopoziomowy-jak-to-wykonac\" class=\"wp-block-heading\"><strong>A curved, multi-level suspended ceiling \u2013 how do you go about it?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A two-level ceiling (with a lowered section or recess) creates a visual effect that allows you to define different zones, conceal recessed LED lighting and add character to your interiors. It is more difficult to install, but certainly possible for an experienced DIY enthusiast.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Multi-level ceiling: UD profiles fixed to the wall define the level of each tier, whilst CD profiles form the load-bearing ribs for the panels.<\/li>\n\n\n\n<li>Curved ceiling: UD profiles, scored every few centimetres (every 2\u20135 cm for tight curves), can be bent into any shape; plasterboard scored from the underside allows the curves to be smoothed out.<\/li>\n\n\n\n<li>The minimum width of the lowered section: 30\u201340 cm, to maintain the proportions and allow space for the light fittings.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Important: <\/strong>A curved ceiling is an advanced project. If you haven\u2019t installed a straight plasterboard ceiling before, start with that.

If you need to conceal thicker services or level out significant unevenness in the ceiling, vernier hangers allow you to lower the ceiling by 20\u2013110 cm from the structural ceiling.<\/p>\n\n\n\n<h3 id=\"czy-sufit-podwieszony-mozna-zrobic-samemu\" class=\"wp-block-heading\"><strong>Can you fit a suspended ceiling yourself?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, and many people do this without any prior experience in building work.

The total weight of the ceiling (panel + structure) is approx. 12\u201315 kg\/m\u00b2.
