Part 4 flat roof construction.
Warm roof construction pitched.
The position of the insulation can be wholly above or partially between and above the rafter.
Insulating the roof above the rafters is known as warm roof insulation as the rafters are brought into the insulated envelope of the building.
Insulating a pitched roof above the rafters is the common method chosen for new builds and re roofing existing detached buildings as it provides superior thermal performance for the building.
Part 3 pitched roof detail.
A warm roof building will make the entire structure of the building warm in an attempt to avoid any cold bridging.
In a warm pitched roof construction the thermal insulation is placed in the rafter line.
Inclined along the line of rafters warm roof or positioned within the roof structure to form an insulated void room in roof which can result in warm and cold roof areas.
In case of warm roofs they have an insulation above the roof deck in this way it keeps the deck warm.
What is a warm roof or a cold roof.
Namely the insulation layers.
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.
Part 1 a guide to roof construction.
Introduction warm cold roofs this guidance offers guidance on the difference benefits between warm and cold roofs.
An architect makes the usual decision of the pitch.
Another aspect of construction to consider is a warm pitched roof construction.
A cold deck roof is where the insulation is placed between the joists rafters or in between the ceiling joists in the case of a pitch roof.
A typical roof pitch in the uk for a traditional house will be 40 50 but at most it can go up to 70.
As it avoids the need for aeration of the roof construction.
Covers an overview of flat and pitched roofs.
Cold roof voids are typically required to be ventilated.
Covers flat roof materials and flat roof construction of warm and cold roofs.
You create a warm roof or a cold roof simply by applying the layers of the roof in a different order.
In building construction roof pitch is a numerical measure of the steepness of a roof.
Covers pitched roof detail.
Ventilation is required for these roofs.
Warm pitched roof construction.
There are typically two different ways to insulate a roof a warm roof and a cold roof.
There are many benefits to this type of construction including making a home more energy efficient and minimizing the thermal bridge at the eaves.
In a cold roof the insulation is applied between the rafters but in a warm roof the insulation is applied on top of the existing roof surface.
This is where you consider the ventilation and sealing of the roof.
