For homeowners in Luxembourg, thermal modernisation is a practical way to cut energy use, lower bills, and stay comfortable all year.<\/p><p>To begin with, you can start by insulating walls and roofs, upgrading heating systems, or installing solar panels. The good news? Luxembourg doesn\u2019t just support these efforts\u2014it helps fund them.<\/p><p>Moreover, with generous grants at both the national and local levels, energy renovation has never been more accessible. Whether you own a house, duplex, or apartment, it\u2019s not just a green choice\u2014it\u2019s a smart financial move.<\/p><p>In this case, thermal modernisation delivers both environmental and economic benefits. What\u2019s more, it increases the long-term value of your home.<\/p><p>In this guide, we\u2019ll show you what thermal modernisation involves, why it matters, and how to get started.

In particular, this is true in Luxembourg\u2019s varied climate.<\/p><p>Without good insulation, even the most advanced heating system will struggle to keep your home warm in winter or cool in summer. Walls, roofs, and floors are the most common areas where heat escapes. As a result, upgrading their insulation can lead to noticeable energy savings.<\/p><p>External wall insulation can cut heat loss by up to 25%. Roof insulation alone can prevent up to 30% of thermal energy from escaping.<\/p><p>Floor insulation \u2014 especially above garages or unheated cellars \u2014 adds extra protection and comfort. Altogether, these improvements deliver the best results. Fortunately, Luxembourg offers strong financial support for such projects. National and local subsidies cover a large part of the cost.<\/p><p>What\u2019s more, with efficient materials and clear energy standards, professional insulation is now a reliable way to save energy and reduce your bills.<\/p>\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-1be2081 e-flex e-con-boxed e-con e-parent\" data-id=\"1be2081\" data-element_type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-4386438 elementor-widget elementor-widget-heading\" data-id=\"4386438\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Replacing windows and heating systems for better efficiency<\/h3>\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-7d89fd2 e-flex e-con-boxed e-con e-parent\" data-id=\"7d89fd2\" data-element_type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-cf6ef6a elementor-widget elementor-widget-text-editor\" data-id=\"cf6ef6a\" data-element_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<p>Old windows and inefficient heating systems are major obstacles to a truly energy-efficient home. In many Luxembourgish buildings \u2014 especially older ones \u2014 single-glazed or poorly sealed windows let valuable heat escape.<\/p><p>Outdated boilers and electric radiators also waste energy without providing consistent comfort. Replacing windows with double or triple-glazed models and insulated frames helps keep the heat in and the cold out.<\/p><p>These thermal modernisation upgrades\u00a0 also improve soundproofing and indoor comfort year-round. Moreover, switching to high-efficiency systems, like air-to-water or geothermal heat pumps, can cut energy use by up to 50%.<\/p><p>The cost may seem high at first. However, Luxembourg\u2019s financial support schemes make these upgrades more affordable.

This applies when the energy class improves by at least two levels.<\/p><p>In addition, other programs include Enoprimes (from energy suppliers), low-interest climate loans, and a reduced 3% VAT for older homes. In some municipalities, you can also get local top-up grants covering 10\u201320% of your renovation costs.<\/p><p>A state-funded energy audit is partly reimbursed, making expert advice easier to access. As a result, these supports can reduce the total cost of deep renovation by up to 60\u201370%, especially when upgrades are combined.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-bcbf0d1 elementor-widget elementor-widget-heading\" data-id=\"bcbf0d1\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\"><span class=\"ez-toc-section\" id=\"Your_step-by-step_plan_for_a_thermal_modernisation_and_more_efficient_home\"><\/span>Your step-by-step plan for a thermal modernisation and more efficient home<span class=\"ez-toc-section-end\"><\/span><\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-70a067f elementor-widget elementor-widget-text-editor\" data-id=\"70a067f\" data-element_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<p>Starting an energy renovation project can feel overwhelming. However, in Luxembourg, there\u2019s a clear path to follow.<\/p><p>The first step is to schedule an energy audit with a certified expert, often subsidised by the state. This evaluation will show where your home is losing energy and what to fix first.<\/p><p>After that, create a renovation plan based on the audit. Many homeowners begin with insulation\u2014walls, roof, and floors\u2014then move on to windows and heating systems. Once energy loss is reduced, you can add solar panels to generate clean electricity and save even more.<\/p><p>With this in mind, at Voltmax, we support you every step of the way.
