that means they lose heat quickly in winter and gather a lot of heat in summer. This results in higher energy bills, uncomfortable indoor temperatures, and increased wear on heating and cooling systems. Proper insulation helps create a stable indoor climate and reduces dependency on energy, which is especially critical as energy costs continue to rise.<\/p>\n<p>In addition to energy savings, insulating an old house also prevents moisture problems and condensation, both of which can lead to structural damage over time. With the right method, it is possible to insulate older properties without changing their design and heritage value.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-b0cf6c8 e-flex e-con-boxed e-con e-parent\" data-id=\"b0cf6c8\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-f1d59eb elementor-widget elementor-widget-image\" data-id=\"f1d59eb\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"800\" height=\"600\" src=\"https:\/\/imenpol.com\/blog\/en\/wp-content\/uploads\/sites\/2\/2025\/10\/insulation-suitable-for-old-houses.jpg\" class=\"attachment-full size-full wp-image-17997\" alt=\"insulation suitable for old houses\" srcset=\"https:\/\/imenpol.com\/blog\/en\/wp-content\/uploads\/sites\/2\/2025\/10\/insulation-suitable-for-old-houses.jpg 800w, https:\/\/imenpol.com\/blog\/en\/wp-content\/uploads\/sites\/2\/2025\/10\/insulation-suitable-for-old-houses-300x225.jpg 300w, https:\/\/imenpol.com\/blog\/en\/wp-content\/uploads\/sites\/2\/2025\/10\/insulation-suitable-for-old-houses-768x576.jpg 768w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-7ee41c6  table-contents e-flex e-con-boxed e-con e-parent\" data-id=\"7ee41c6\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-9c7f12d elementor-widget elementor-widget-text-editor\" data-id=\"9c7f12d\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\n<h2>Types of insulation suitable for old houses<\/h2>\n\n<p>When considering insulation for older homes, different areas of the building require tailored solutions. Each method offers unique benefits depending on the structure and condition of the property; including:<\/p>\n<h3>1. Internal wall insulation<\/h3>\n<p>Internal <a title=\"wall insulation\" href=\"\/blog\/en\/educational\/why-insulation-of-walls-is-important\/\" target=\"_blank\" rel=\"noopener\">wall insulation<\/a> includes adding insulation boards or layers inside the home. This method is often chosen when external modifications are not possible due to heritage restrictions or aesthetic concerns. While it slightly reduces interior space, it can provide excellent thermal efficiency and improve the overall comfort of living spaces.<\/p>\n<h3>2. External wall insulation<\/h3>\n<p>External wall insulation is applied on the outer walls of the building, usually covered with a protective finish like render or cladding. This option provides outstanding energy savings and protects the structure from weather damage. It can also give the property a refreshed appearance, though it may not be suitable for historically protected facades.<\/p>\n<h3>3. Loft and attic insulation<\/h3>\n<p>A significant amount of heat is lost through the roof in older houses. Insulating the loft or attic is one of the most cost-effective solutions. It prevents heat from escaping in winter and keeps the house cool in summer. Both roll insulation materials and spray foam are commonly used in loft insulation projects.<\/p>\n<h3>4. Floor and basement insulation<\/h3>\n<p>Cold air can enter through floors and basements, making living spaces uncomfortable. Adding insulation under floors\/floorings, in crawl spaces, or along basement walls helps reduce drafts and improves indoor temperature. Modern insulation materials are highly effective in these areas, preventing energy loss and moisture problems.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-1d8889b section pd-0 pb-0 pt-0 e-flex e-con-boxed

materials<\/h2>\n\n\n\n<p>Selecting the right material is essential for ensuring durability, thermal performance, and compatibility with the structure of an older house. In the following, some of the most commonly used insulation materials are mentioned.<\/p>\n<h3>1. Polyurethane foam (PU foam)<\/h3>\n<p><a title=\"Polyurethane\" href=\"\/en\/polyurethane\/\" target=\"_blank\" rel=\"noopener\">Polyurethane<\/a> foam is generally known as one of the best insulation solutions for old houses. It offers excellent thermal resistance, air sealing, and moisture protection. Spray-applied PU foam can fill gaps and irregular spaces, making it ideal for renovation without requiring major structural changes. Its high performance ensures maximum energy efficiency even in difficult areas like attics, basements, and cavity walls. In other words, polyurethane insulations can come in different shapes and application methods.<\/p>\n<h3>2. Fiberglass &amp; rockwool<\/h3>\n<p>Fiberglass and rockwool are traditional insulation materials that remain popular due to their affordability and ease of installation. They provide good fire resistance and soundproofing qualities. However, compared to polyurethane foam, they cannot offer the same level of air sealing and long-term performance in older houses.<\/p>\n<h3>3. Polyiso and PIR<\/h3>\n<p>Polyisocyanurate (polyiso) and polyisocyanurate <a title=\"rigid polyurethane foam\" href=\"\/en\/hard-foam\/\" target=\"_blank\" rel=\"noopener\">rigid foam<\/a> boards (PIR) are lightweight yet highly efficient insulation materials. They are particularly suitable for roof and wall applications, providing strong thermal performance in thin layers. These materials can also be used in combination with other insulation systems for enhanced energy savings.<\/p>\n<h3>4. Natural insulation: hemp and sheep\u2019s wool<\/h3>\n<p>For homeowners looking for eco-friendly solutions, natural insulation materials such as hemp fiber and sheep\u2019s wool are excellent options. They are breathable, sustainable, and provide good thermal performance. They cannot insulate as well as <a title=\"polyurethane foam\" href=\"\/blog\/en\/educational\/what-is-polyurethane-foam\/\" target=\"_blank\" rel=\"noopener\">polyurethane foam<\/a>, but they are a good choice for eco-friendly projects and keeping the natural style of old houses. Also, it has to be mentioned that they may sag over time or absorb moisture, which can lead to mold growth.<\/p>\n\n\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-6358fe0 section related-products e-flex e-con-boxed

available insulation materials on the market, polyurethane foam is known as the most effective insulation for old houses. Its ability to expand and seal every corner ensures there are no gaps for heat to escape. Unlike fiberglass or rockwool, PU foam also acts as an air and moisture barrier; it adheres well to different substrates, making it particularly suitable for structures with uneven surfaces or hidden cavities. This seamless coverage allows homeowners to achieve consistent insulation performance even in areas that are difficult to access or irregular in shape. Its ability to conform to complex architectural features makes it a practical choice for preserving the structural and aesthetic integrity of historical homes.<\/p>\n<p>Polyurethane foam provides long-lasting insulation that needs little maintenance, making it a cost-effective solution in the long term. Homeowners who choose PU foam for their old houses benefit from reduced energy bills, improved comfort, and extended building lifespan.<\/p>\n<h2>Buying polyurethane in Iran for home insulation<\/h2>\n\n<p>For those in Iran looking to change\/improve their home insulation, high-quality <a title=\"polyurethane raw materials\" href=\"\/blog\/en\/educational\/raw-materials-of-polyurethane-foam\/\" target=\"_blank\" rel=\"noopener\">polyurethane raw materials<\/a> are available from trusted local suppliers.

While several insulation methods and materials are available, polyurethane foam has become the most popular and the most effective choice for older structures. Its ability to seal gaps, provide superior thermal resistance, and protect against moisture makes it the ideal solution for houses that were not originally designed with proper high R-value insulation.<\/p>\n<p>For homeowners who are planning to insulate their old houses, sourcing high-quality polyurethane materials is essential. <a title=\"Imen Polymer Chemie\" href=\"\/en\/\" target=\"_blank\" rel=\"noopener\">Imen Polymer Chemie<\/a>, as a trusted manufacturer of polyurethane raw materials, provides reliable solutions tailored to insulation projects.
