Warm Pitched Roof System

When used in roofs tyvek and airguard membranes provide optimal protection of the thermal insulation and reduce the risk of interstitial condensation enhancing the energy efficiency of the building.

Warm pitched roof system.

Warm pitched roof construction. As opposed to insulating between rafters the warm roof insulation is simply installed on top of the existing surface. Insulating a pitched roof above the rafters. When it comes to flat roofs international best practice is to use warm roof designs.

Alternatively it can be positioned between the rafters or partially between and below the rafter. This results in the structural deck and its supports being at a temperature closer to that of the building s interior. Warm roof insulation tends to relate more to pitched roofs which feature as mentioned in the previous sentence a higher profile. Insulating the roof above the rafters is known as warm roof insulation as the rafters are brought into the insulated envelope of the building.

Installing a warm roof can be extremely straight forward and simple to do. The construction of a warm roof the insulation sits on top of the rafters. A warm roof building will make the entire structure of the building warm in an attempt to avoid any cold bridging. Basically there are two options to choose from when insulating a flat roof.

With a codemark certificate for added confidence it may be installed at 1 degree for maximum design freedom. When used in conjunction with a breathable membrane such as roofshield or an equivalent it removes the need for ventilation of the roof void. With a warm roof the insulation is installed on top of the existing surface rather than in between the rafters. These designs put the insulation above the substrate completely enclosing the roof area with a highly efficient insulation layer.

Our pitched roof panels are designed for use in warm pitched roof applications to provide a high level of insulation and are designed to insulate both the rafters as well as the roof and prevent the rafters forming a cold bridge. A warm roof construction has many benefits over a traditional cold roof essentially it is a breathable roof construction which allows moisture to escape which in turn prevents damp and any associated decay problems. In a warm pitched roof construction the thermal insulation is placed in the rafter line. The position of the insulation can be wholly above or partially between and above the rafter.

With the potential of additional living space a cathedral roof design or a conditioned roof void are rapidly becoming the preferred choice of pitched roof construction in the uk. Warm roofs offer a superior thermal performance and therefore come with a higher cost. On flat roofs a warm roof is one in which the insulation layer is laid on top of roof structure. In building construction roof pitch is a numerical measure of the steepness of a roof.

Due to their breathable nature tyvek membranes offer benefits over traditional impermeable roofing underlays commonly used in warm pitched roof construction by reducing the risk of interstitial condensation occurring within roof constructions.
