Whether you are a distributor sourcing for a villa development, a contractor fitting out apartments, or a homeowner renovating, this guide walks through the factors that actually matter on site and in the showroom.<\/p>\n<h2>1. Match the Door to the Room Function<\/h2>\n<p>Not every room needs the same door. Bedrooms and home offices benefit from solid-core or <a href=\"https:\/\/kent-china.com\/zh\/interior-door\/\">wooden interior door<\/a> options that dampen sound. Bathrooms and kitchens need moisture-resistant skins and a tight seal. Closets and utility rooms can use lighter, cost-efficient panels. Defining the function first prevents over-specifying (wasted budget) or under-specifying (poor performance).<\/p>\n<h2>2. Material: Wood, UPVC, Aluminum, or WPC<\/h2>\n<p>Each material carries trade-offs:<\/p>\n<ul>\n<li><strong><a href=\"https:\/\/kent-china.com\/zh\/wooden-vs-upvc-vs-aluminum-interior-doors-which-to-import\/\">Wooden doors<\/a><\/strong> \u2013 Premium look, warm feel, best for high-end villas; needs stable humidity.<\/li>\n<li><strong>UPVC doors<\/strong> \u2013 Affordable, waterproof, ideal for humid climates and rental stock.<\/li>\n<li><strong>Aluminum doors<\/strong> \u2013 Slim, durable, modern; pairs well with <a href=\"https:\/\/kent-china.com\/zh\/window-and-door\/\">\u95e8\u7a97<\/a> systems.<\/li>\n<li><strong>WPC (wood-plastic composite)<\/strong> \u2013 Termite-proof, dimensionally stable, low maintenance.<\/li>\n<\/ul>\n<p>For most export markets, a mix of wooden doors for living zones and WPC or UPVC for wet areas gives the best value.<\/p>\n<h2>3. Sizing and Opening Direction<\/h2>\n<p>Standard leaf widths are 600\u20131000&nbsp;mm. Always confirm rough-opening dimensions from the architect before ordering, and decide swing direction (inswing\/outswing) and left\/right handing. For retrofit projects, measure the existing frame rather than the leaf.<\/p>\n<h2>4. Soundproofing and Fire Rating<\/h2>\n<p>If the project targets apartments or hotels, ask for a tested STC (Sound Transmission Class) rating\u2014typically STC&nbsp;28\u201332 for solid-core doors. Fire-rated cores (30\/60&nbsp;min) are mandatory in many commercial and multi-family codes; pair them with certified frames and seals.<\/p>\n<h2>5. Surface Finish and Hardware Prep<\/h2>\n<p>Factory-primed or prepainted leaves save on-site labor. Confirm hardware preparation: pre-bored lockset holes, hinge mortises, and whether the door ships as a slab or pre-hung unit. Pre-hung doors speed installation and improve alignment.<\/p>\n<h2>6. Import and Logistics Considerations<\/h2>\n<p>When importing, verify packaging (foam-corner + carton + wooden crate for containers), lead time, and whether the <a href=\"https:\/\/kent-china.com\/zh\/interior-door\/\">interior door supplier<\/a> provides CAD drawings and certification (CE, ISO9001). Consolidating doors with <a href=\"https:\/\/kent-china.com\/zh\/window-and-door\/\">\u95e8\u7a97<\/a> in one shipment reduces freight cost per unit.<\/p>\n<h2>Frequently Asked Questions<\/h2>\n<h3>Which interior door is best for a humid climate?<\/h3>\n<p>WPC or UPVC skins resist swelling and termite damage better than solid wood in coastal and tropical regions.<\/p>\n<h3>Should I buy slabs or pre-hung doors?<\/h3>\n<p>Pre-hung units install faster and align better, especially for non-professional labor. Slabs are cheaper but need skilled carpentry.<\/p>\n<h2>Get a Custom Quote<\/h2>\n<p>KENT manufactures wooden, WPC, UPVC, and aluminum <a href=\"https:\/\/kent-china.com\/zh\/interior-door\/\">interior doors<\/a> with OEM\/ODM options, CAD support, and global shipping. <a href=\"https:\/\/kent-china.com\/zh\/contact-us\/\">Contact our team<\/a> with your project drawings for a tailored quotation within 24&nbsp;hours.<\/p>","protected":false},"excerpt":{"rendered":"<p>Choosing the right interior door is one of the most overlooked decisions in a residential build, yet it shapes daily<\/p>","protected":false},"author":3,"featured_media":1370,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"_seopress_titles_title":"How to Choose Interior Doors for Residential Projects | KENT","_seopress_titles_desc":"A practical guide to selecting interior doors for villas, apartments, and homes\u2014materials, sizes, soundproofing, and import tips from a building materials manufacturer.","_seopress_robots_index":"","_seopress_robots_follow":"","_seopress_robots_imageindex":"","_seopress_robots_snippet":"","_seopress_robots_primary_cat":"","_seopress_robots_breadcrumbs":"","_seopress_robots_freeze_modified_date":"","_seopress_robots_custom_modified_date":"","_seopress_robots_canonical":"","_seopress_social_fb_title":"","_seopress_social_fb_desc":"","_seopress_social_fb_img":"","_seopress_social_fb_img_attachment_id":0,"_seopress_social_fb_img_width":0,"_seopress_social_fb_img_height":0,"_seopress_social_twitter_title":"","_seopress_social_twitter_desc":"","_seopress_social_twitter_img":"","_seopress_social_twitter_img_attachment_id":0,"_seopress_social_twitter_img_width":0,"_seopress_social_twitter_img_height":0,"_seopress_redirections_value":"","_seopress_redirections_enabled":"","_seopress_redirections_enabled_regex":"","_seopress_redirections_logged_status":"","_seopress_redirections_param":"","_seopress_redirections_type":0,"_seopress_analysis_target_kw":"","footnotes":""},"categories":[1],"tags":[],"class_list":["post-1371","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-door-buying-guide"],"_links":{"self":[{"href":"https:\/\/kent-china.com\/zh\/wp-json\/wp\/v2\/posts\/1371","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/kent-china.com\/zh\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/kent-china.com\/zh\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/kent-china.com\/zh\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/kent-china.com\/zh\/wp-json\/wp\/v2\/comments?post=1371"}],"version-history":[{"count":3,"href":"https:\/\/kent-china.com\/zh\/wp-json\/wp\/v2\/posts\/1371\/revisions"}],"predecessor-version":[{"id":1402,"href":"https:\/\/kent-china.com\/zh\/wp-json\/wp\/v2\/posts\/1371\/revisions\/1402"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/kent-china.com\/zh\/wp-json\/wp\/v2\/media\/1370"}],"wp:attachment":[{"href":"https:\/\/kent-china.com\/zh\/wp-json\/wp\/v2\/media?parent=1371"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/kent-china.com\/zh\/wp-json\/wp\/v2\/categories?post=1371"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/kent-china.com\/zh\/wp-json\/wp\/v2\/tags?post=1371"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
