Insulating the roof above the rafters is known as warm roof insulation as the rafters are brought into the insulated envelope of the building. This over-rafter insulation method also reduces thermal bridging, giving an airtight continuous layer of high-performance insulation and results in a well-insulated attic space.

In this guide, we'll cover key considerations for insulating pitched roofs, including construction methods, types of insulation, U-values, and how to prevent condensation. This information will assist you in making informed decisions when designing a new roof or enhancing the energy efficiency of your home.

Warm Roof/Deck (Sandwich roof) Warm roof systems benefit from the insulation sitting above the deck. This enables the temperature of the structure and the deck to be kept close to the temperature of the inside of the building (hence warm).

2023年6月17日 · We're having a roughly 9 x 4m extension on the rear of the house, warm flat roof with a few roof lights and 450mm overhang.

Typical details for a “warm” flat roof (U.K.); drawing via BuildingRegs4Plans. To put together a warm deck roof, it’s important that the insulation be positioned above the structural deck — the layers that make up the ceiling. Zero ventilation space is required, and the construction appears stacked and compact.

Warm roof construction is where the roof insulation is fitted above the rafters, therefore bringing the rafters into the insulated envelope of the building. It is the most thermally efficient way of fitting roof insulation.

2015年1月7日 · The following figures are intended as a guide to demonstrate the general principles of the flat roof, detailing commonly used on flat roofs, terraces and balconies. Where indicated, the principles are applicable to other types of roof construction.

2022年4月6日 · In building construction, roof pitch is a numerical measure of the steepness of a roof. There are typically two different ways to insulate a roof - a warm roof and a cold roof. A warm roof will make the entire structure of the building warm in an attempt to avoid any cold bridging.
