Types, Advantages and Usage Areas"},"content":{"rendered":"<p><strong>Sandwich panel<\/strong>is one of the most preferred materials in the modern construction sector. With its lightweight structure, high insulation performance and quick installation capability, it has a wide range of applications from industrial facilities to residential projects. So, <strong>what is sandwich panel<\/strong>, what types are available and why is it so widely used?<\/p>\n<h2>What Is Sandwich Panel?<\/h2>\n<p>A sandwich panel is a composite structural element manufactured by placing insulation material between two metal sheets (typically galvanized or painted steel sheet). While the metal sheets on the outer surfaces provide structural durability, the filling material inside fulfils critical functions such as thermal, acoustic and fire insulation.<\/p>\n<p>Sandwich panels are prepared under controlled factory conditions and dispatched to the construction site as ready-made modules. Today, the use of sandwich panels in the construction sector offers much faster, more economical and sustainable solutions compared to traditional building materials.<\/p>\n<h2>Sandwich Panel Types<\/h2>\n<p>Sandwich panels are divided into different categories based on the insulation material used. <a href=\"https:\/\/velisltd.com\/en\/sandvic-panel\/\">Velis LTD sandwich panel product range<\/a>covers all types needed by the industry.<\/p>\n<h3>1. EPS Sandwich Panel (Polystyrene-Filled)<\/h3>\n<p>EPS (Expanded Polystyrene) filled sandwich panels are the most widely used type. They stand out with their lightweight structure, economical price and good thermal insulation performance. EPS roof panels are generally produced in thicknesses ranging from 40 mm to 200 mm.<\/p>\n<p><strong>Technical specifications:<\/strong><\/p>\n<ul>\n<li>Density: 16\u201320 kg\/m\u00b3<\/li>\n<li>Thermal conductivity coefficient (\u03bb): 0.035\u20130.040 W\/mK<\/li>\n<li>Panel width: 1000 mm (effective width)<\/li>\n<li>Thickness options: 40, 50, 60, 80, 100, 120, 150, 200 mm<\/li>\n<\/ul>\n<h3>2. Rock Wool (Stone Wool) Sandwich Panel<\/h3>\n<p>Rock wool filled sandwich panels are the premium panel type preferred in projects where fire resistance and acoustic insulation are of primary importance. They fall within the A1 class non-combustible material category and can withstand temperatures above 1,000\u00b0C.<\/p>\n<p><strong>Technical specifications:<\/strong><\/p>\n<ul>\n<li>Fire class: A1 (non-combustible)<\/li>\n<li>Thermal conductivity coefficient (\u03bb): 0.035\u20130.038 W\/mK<\/li>\n<li>Sound insulation performance: Rw = 25\u201335 dB<\/li>\n<li>Maximum operating temperature: 750\u00b0C<\/li>\n<\/ul>\n<h3>3. Polyurethane (PUR\/PIR) Sandwich Panel<\/h3>\n<p>This is the panel type offering the highest thermal insulation performance. It provides approximately 40% better insulation compared to an EPS panel of the same thickness. It is preferred for cold storage facilities and buildings where energy efficiency must be maintained at the highest level.<\/p>\n<h2>Advantages of Sandwich Panel<\/h2>\n<h3>High Thermal Insulation Performance<\/h3>\n<p>In hot summer climates such as North Cyprus, using sandwich panels of the correct thickness can reduce air conditioning costs by 30\u201350%.<\/p>\n<h3>Fast and Easy Installation<\/h3>\n<p>Compared to traditional brick-laying and plastering processes, sandwich panel installation is completed 60\u201370% faster. A team can install an average of 200\u2013300 m\u00b2 of panels per day.<\/p>\n<h3>Economical Solution<\/h3>\n<p>Fast installation reduces labor costs; its lightweight structure lowers transportation costs. The total cost advantage compared to traditional construction methods can range from 20\u201340%.<\/p>\n<h3>Fire and Sound Insulation<\/h3>\n<p>Rock wool filled panels hold an A1 class non-combustibility certificate and have a sound reduction capacity of 25\u201335 dB.<\/p>\n<h2>Sandwich Panel Application Areas<\/h2>\n<ul>\n<li><strong>Industrial Buildings:<\/strong> Factories, production facilities, workshops and warehouse buildings<\/li>\n<li><strong>Commercial Buildings:<\/strong> Shops, showrooms, shopping centres<\/li>\n<li><strong>Cold Storage Facilities:<\/strong> Food processing facilities<\/li>\n<li><strong><a href=\"https:\/\/velisltd.com\/en\/konteyner\/\">Container<\/a> ve Prefabrik Yap\u0131lar:<\/strong> <a href=\"https:\/\/velisltd.com\/en\/konteyner\/\">Container homes<\/a>, tiny house projects<\/li>\n<li><strong>Agricultural Buildings:<\/strong> Farm buildings, greenhouses<\/li>\n<li><strong>Sports Facilities:<\/strong> Indoor sports halls, swimming pools<\/li>\n<\/ul>\n<h2>EPS vs. Rock Wool Comparison<\/h2>\n<figure class=\"wp-block-table\">\n<table>\n<thead>\n<tr>\n<th>Feature<\/th>\n<th>EPS Panel<\/th>\n<th>Rock Wool Panel<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Fire Class<\/td>\n<td>Class B<\/td>\n<td>A1 (non-combustible)<\/td>\n<\/tr>\n<tr>\n<td>Weight (80 mm)<\/td>\n<td>~10 kg\/m\u00b2<\/td>\n<td>~22 kg\/m\u00b2<\/td>\n<\/tr>\n<tr>\n<td>Sound Insulation<\/td>\n<td>Medium<\/td>\n<td>High<\/td>\n<\/tr>\n<tr>\n<td>Price<\/td>\n<td>Economical<\/td>\n<td>Medium-High<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/figure>\n<h2>How to Choose a Sandwich Panel?<\/h2>\n<ol>\n<li><strong>Determine your application:<\/strong> Roof or wall?<\/li>\n<li><strong>Fire safety:<\/strong> Rock wool may be mandatory in regulation-governed projects<\/li>\n<li><strong>Climate conditions:<\/strong> In North Cyprus, a minimum thickness of 80\u2013100 mm is recommended for roofs<\/li>\n<li><strong>Budget:<\/strong> EPS is the most economical; rock wool is preferred for fire safety<\/li>\n<li><strong>Reliable manufacturer:<\/strong> <a href=\"https:\/\/velisltd.com\/en\/sandvic-panel\/\">Velis LTD<\/a>, a pioneer in North Cyprus with 27 years of experience<\/li>\n<\/ol>\n<h2>Frequently Asked Questions<\/h2>\n<h3>What is the lifespan of a sandwich panel?<\/h3>\n<p>With quality manufacturing and proper installation, it offers a service life of 25\u201330 years. Regular maintenance can extend this period.<\/p>\n<h3>What factors affect sandwich panel prices?<\/h3>\n<p>The type of filling material, panel thickness, sheet thickness, order quantity and delivery distance are the main factors that determine the price.<\/p>\n<h3>Is sandwich panel installation difficult?<\/h3>\n<p>When carried out by an experienced team, it is quite fast and easy. The installation of an average industrial building can be completed in 1\u20132 weeks.<\/p>\n<h3>Can a house be built from sandwich panel?<\/h3>\n<p>Yes. Tiny house and <a href=\"https:\/\/velisltd.com\/en\/konteyner\/\">container home<\/a> projects use it successfully as the primary structural material.<\/p>\n<h3>Should I choose EPS or rock wool?<\/h3>\n<p>EPS is sufficient for general-purpose buildings. Rock wool should be preferred for buildings requiring fire and acoustic insulation.<\/p>\n<hr\/>\n<p><strong>Velis LTD<\/strong> with over 27 years of experience <a href=\"https:\/\/velisltd.com\/en\/sandvic-panel\/\">our sandwich panel products<\/a> contact us for detailed information and a price quote.<\/p>\n<div class=\"ilgili-yazilar\" style=\"margin-top:20px;padding:20px;background:#eef6ff;border-radius:8px;\">\n<h3 style=\"margin-top:0;\">\u0130lgili Yaz\u0131lar<\/h3>\n<ul>\n<li><a href=\"https:\/\/velisltd.com\/en\/konteyner-ev-kibris-rehberi\/\">Konteyner Ev Rehberi<\/a><\/li>\n<li><a href=\"https:\/\/velisltd.com\/en\/trapez-sac-secim-rehberi\/\">Trapez Sa\u00e7 Se\u00e7im Rehberi<\/a><\/li>\n<\/ul>\n<\/div>\n<div class=\"ilgili-urunler\" style=\"margin-top:30px;padding:20px;background:#f5f5f5;border-radius:8px;\">\n<h3 style=\"margin-top:0;\">\u0130lgili \u00dcr\u00fcnlerimiz<\/h3>\n<ul>\n<li><a href=\"https:\/\/velisltd.com\/en\/sandvic-panel\/\">Sandwich Panel<\/a><\/li>\n<li><a href=\"https:\/\/velisltd.com\/en\/konteyner\/\">Container<\/a><\/li>\n<li><a href=\"https:\/\/velisltd.com\/en\/trapez-sac\/\">Trapezoidal Sheet<\/a><\/li>\n<\/ul>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Sandvi\u00e7 panel, modern yap\u0131 sekt\u00f6r\u00fcn\u00fcn en \u00e7ok tercih edilen malzemelerinden biridir.
