Roof renovations are essential for protecting your home against harsh outdoor climates. A leaking roof probably means you should start considering a renovation project. Your home is not just vulnerable to water leaks, but it could also be leaking heat. If not addressed, you could end up paying hundreds – if not thousands – of Euros in additional energy costs. Stone wool insulation can help protect your interior against water damage, limit your thermal losses, and improve the fire resilience of your property.

By improving the thermal performance of your building, you can cut down on energy costs and provide healthier indoor living environments for the occupants.

Relevant applications

Improving the energy-efficiency of your home

As heat rises, you could be losing as much as 25 percent of your heating energy through your roof if you do not have adequate insulation installed. Renovating your home with modern insulating materials like stone wool could reduce your energy costs and save you up to 70 percent in heating and cooling expenses.

By installing stone wool insulation in your roof, you can improve the overall thermal performance of your home, making sure you can stay warm in winter and cool in summer. Whether you are renovating an existing roof or replacing the entire outer layer of your building, stone wool insulation remains a long-lasting and sustainable solution for your remodelling project.

Select durable materials for the project

If you have to remodel or replace your roof, you should also take the opportunity to select more durable materials than were available during the initial construction. Usually, a roof renovation becomes essential after about 25 years. Once you have reached this stage, you will need to consider what solutions are available on the market that can help extend the useful life of the property and can provide adequate protection long into the future.

Even if you do not need to completely replace your roof but see that energy costs are rising, it is also the perfect time to review your current insulation solutions and replace them with a more reliable product. ROCKWOOL’s stone wool insulation will ensure you can maximise the lifetime of the property by protecting the construction elements from mould or mildew, and halt those runaway heating and cooling expenses.

Roof types and materials

Depending on the type of roof – flat or pitched – you will need to consider what materials to use for the covering, sheathing, and connections. While many different styles like a dormer, hip, and gable remain popular in new and older homes, each one of these construction types can benefit from installing superior insulation inside the building.

Pitched roofs also provide the opportunity to extend the usable living area by converting the loft space. If this is part of your project, you should consider the insulation materials below to help you create a comfortable addition to your home.

stone wool insulation</a> in a pitched roof will ensure you limit thermal losses and reduce the energy consumption required to heat and cool the property. You will also improve the acoustic performance of the building while increasing the fire resilience by insulating your pitched roof. The method of installation depends on your building and project type.</p><p><strong>The available options include:</strong></p><ul><li><strong>Installing insulation above the rafters</strong> &ndash; If you are replacing the entire roof, you may want to opt for installing stone wool insulation above the rafters. This buys you the most space inside your attic making it especially suited if you are also considering a loft conversion.</li><li><strong>Using insulation below the rafters</strong> &ndash; The easiest solution but also takes up the most space. To improve the thermal performance of the building and reduce energy consumption, you can install stone wool insulation under the loadbearing elements of the roof and is a good option if the loss of space is not a problem.</li><li><strong>Insulating between the rafters</strong> &ndash; Installing stone wool insulation between the rafters is the middle ground and can also be combined with insulation below the rafter for maximal energy efficiency. This saves space compared to insulating below the rafters, yet can be done from the inside, avoiding the removal of the roof.</li></ul><h3>Flat roof renovation</h3><p>Flat roofs present a slightly different challenge. This is usually done from the outside, adding insulation layers top of an existing roof or roof structure made from concrete, steel or wood. On top of the insulation is a layer weatherproof membrane to help protect the underlying structure and keep everything dry. Similar to the pitched roof, insulating your flat roof can increase the thermal performance of the building while also reducing the harmful effects of external noise pollution. With stone wool insulation, you can protect the building for its entire usable life and often extend the structure&rsquo;s functional performance for decades to come.</p>","columnTwo":"","primaryButtonTwo":{"componentName":"PrimaryButton","title":"Pitched roof
