A pitched roof is a type of roof that slopes downward at an angle, typically from a central ridge or peak to the eaves (the lower edges of the roof). This design is commonly used in residential and commercial buildings. Pitched roofs are known for their triangular or trapezoidal shape when viewed from the side. The steepness of the slope, also known as the “pitch,” can vary significantly based on architectural style, climate considerations, and other factors. Some people also refer to pitched roofs as 'gable roofs'.

Pitched roofs have several advantages, which includes aesthetic appeal as well as water drainage. The pitched design can prevent water from pooling and therefore reducing the risks of leaks or water damage. Many people opt for a house with a pitched roof as it can provide extra loft space. This space can be converted to become a bedroom or living space. Another benefit of pitched roofs is that they often have vents at the ridge and eaves that promote natural airflow, aiding in proper ventilation of the building. Pitched roofs look great, which means the overall aesthetics of the building is improved. Lastly, pitched roofs are easy to insulate. A building with no pitched roof insulation can lose up to 25% of heat, which demonstrates how important it is to insulate a pitched roof.

The benefits of insulating a pitched roof

Insulating a pitched roof brings about numerous advantages for a building's energy efficiency, comfort, and overall functionality. Effective insulation for pitched roofs substantially curtails heat loss during colder months and heat gain during warmer months, leading to reduced reliance on heating and cooling systems. This results in lower energy expenses and carbon emissions. By stabilising indoor temperatures and preventing drastic temperature fluctuations, insulation contributes to a consistently pleasant living or working environment throughout the entire year.

Beyond these benefits, insulating a pitched roof serves as a safeguard for the roof structure, mitigating temperature-induced expansion and contraction that can strain roofing materials. This preservation can extend the roof's lifespan and prevent the necessity for frequent repairs or replacements. Moreover, insulated pitched roofs can act as a supplementary sound barrier, lessening the intrusion of noise pollution.

Arguably the most noteworthy advantage of pitched roof insulation lies in its environmental impact. Enhanced energy efficiency brought about by roof insulation substantially reduces a building's carbon footprint. This lessens the demand for heating and cooling energy, which is frequently derived from fossil fuels. As energy costs rise, well-insulated homes gain appeal among buyers. In fact, well-insulated homes can fetch higher prices on the market.

When insulating a pitched roof, it's imperative to select the appropriate insulation material and installation approach based on variables such as climate, budget, local building codes, and the existing roof structure. Ensuring adequate ventilation is also crucial to prevent moisture buildup and uphold the roof and insulation system's longevity. Seeking guidance from professionals specialised in roofing can help you pick the right pitched insulation product for your project.

Pitched roof insulation between rafters

On our website, we sell pitched roof insulation for between rafters. People often use fiberglass batts as pitched roof insulation between rafters. This a cost effective option. Rockwool manufacture mineral wool batts, which provide good thermal and sound insulation along with fire resistance.

When choosing insulation for pitched roof insulation between rafters, several factors should be considered, including your budget, desired insulation performance, available space, and local climate. You should also decide if you want to create a cold or warm roof system.

Insulating between rafters of a pitched roof is a common way to effectively insulate your roof. When it comes to choosing pitched roof insulation between rafters, you should firstly know if you want to create a cold pitched roof or a warm pitched roof. If you are unsure then we suggest that you consult a building professional

The difference between a cold pitched roof and a warm pitched roof?

The major difference between a cold pitched roof and a warm pitched roof is the location of the insulation itself. In a warm roof, the insulation is located above and between the rafters. This is to keep the rafters warm. Where as a cold roof features insulation which is below and between the rafters so that the rafters remain cold.

A warm pitched roof design aims to envelop the entire building structure in warmth, eliminating any potential cold bridging. This approach involves incorporating a continuous layer of insulation positioned above the rafters and directly beneath the weatherproof membrane. Embracing a warm roof construction offers numerous advantages over the more conventional “cold roof” approach. Essentially constituting a “breathable roof construction,” it facilitates moisture escape, effectively thwarting dampness and the subsequent issues of decay. By conserving heat within the property, a warm roof construction eliminates the necessity for a ventilation system.

A warm roof design is common in the UK. Premium-performance phenolic insulation boards and high-performance PIR insulation boards are ideal. These boards are suitable for insulating roof spaces in both warm and cold pitched roofs, positioned under tiles or slates. This includes Celotex PIR boards as well as specialist boards such as Kingspan's K107 pitched roof insulation.

In a cold pitched roof configuration, insulation is situated either between the rafters or a combination of between and under them. If your residence is within an older building, your roofing underlay might consist of sarking felt. In such cases, it becomes necessary to allocate a 50 mm gap for ventilation between the insulation and the upper portion of the rafters. For cold pitched roof systems, it is recommended by Kingspan to use a product such as Kingspan's K118 insulated Plasterboard.
