The Importance of Insulation in Pitched Roof Refurbishments
Roof insulation is a vital part of the refurbishment process in many projects, offering a highly effective way to reduce the escape of heat through the top of your property. As a popular roofing choice for education, housing and public facilities, improving efficiency and maximising temperature retention in colder months is integral for reducing heating costs.
In this guide, we explain the importance of insulation for pitched roof refurbishments, including the key benefits of including insulation in your project.
What is Pitched Roof Insulation?
Pitched roof insulation is a method for reducing heat wastage from your building through the installation of insulation materials, such as mineral wool, foam boards or spray foam. By slowing heat loss from the property in autumn and winter and reducing heat ingress in warmer months, insulation helps to maintain a continuous temperature – reducing heating and cooling costs.
Central Group are specialists in pitched roofing installation and insulation, including providing high-quality solutions for the education and residential sectors. Our team offers pitched roofing installations, where insulation is installed below the roof before we complete any refurbishment work as required, to improve energy efficiency and reduce your carbon footprint.
Cold Pitched Roof Insulation
Cold pitched roof insulation involves placing insulation at ceiling or joist level. With this method, the roof itself is not insulated and remains ‘cold’, with a space between the insulation materials and your roofing for air ventilation. Cold pitched roof insulation is a cost-effective solution for pre-existing roofing, as it is built below, rather than into, the roofing structure.
Warm Pitched Roof Insulation
Warm pitched roof insulation is a more involved method of insulation, where insulation is installed both above and between the rafters. Properties that have usable attic spaces may prefer this option, as it offers full insulation for the loft space and provides more room to access and utilise the space. Warm pitched roof insulation is typically more expensive and labour-intensive.
Benefits of Pitched Roof Insulation
Installing pitched roof insulation has many benefits for properties of all sizes. These include:
– Occupant comfort: In live environments, installing pitched roof insulation is a key component in making indoor spaces livable, retaining heat and preventing uncomfortable temperature changes.
– Compliance: Insulation enables your property to meet UK Building Regulations (Part L) in relation to specific thermal efficiency in new builds and renovations.
– Lifecycle performance: Pitched roofing with insulation helps to improve the lifecycle of buildings by helping to manage condensation and reducing thermal stress.
– Reduced maintenance costs: Insulation in your pitched roof helps to reduce maintenance costs caused by structural stress, moisture damage and ice dams.
– Improved heat retention: Proper insulation keeps heat inside the property for longer, ensuring more stable and safe temperatures in the colder seasons.
– Reduced heat ingress: During summer, roofing insulation reduces heat ingress, which helps to lessen the amount of cooling required for safe working.
– Better energy efficiency: By preventing significant swings in temperatures, businesses can reduce their energy costs while ensuring the interior is comfortable for use.
– Lower carbon footprint: Preventing heat loss reduces the carbon footprint of the property, improving the sustainability of your business.
Best Materials for Pitched Roof Installation
Insulation or pitched roofing can be made of a range of different materials. A professional installer will be able to identify the best option for your property following an on-site inspection. Some of the options available for pitched roof installation include:
– Mineral wool: A sustainable option made from wool or rock. This option is extremely popular, as it is cost-effective and is available in rolls or blankets that can easily be cut to size and fitted in a range of locations on pitched roofs.
– Fibreglass: Similar to mineral wool but made from recycled glass, fibreglass is highly cost-effective and is suitable for recycling. Fibreglass is also available in blankets or rolls to be cut to whatever size is required.
– PIR board: These insulation boards have a high thermal efficiency, as they are made from a synthetic polymer. PIR boards are more expensive but are highly flame, mould and moisture resistant.
– Corkboard: Cork is a more sustainable type of insulation board, with excellent heat retention. Corkboard is a rigid material that is recyclable, making it a good middle ground between softer materials and less eco-friendly solutions.
