Quinn therm qrfr ffr insulation is a foil faced insulation board which helps further improve the thermal performance to help achieve the desired u value.
Insulating a concrete slab roof.
Of course it doesn t have to be that way if the concrete slab is insulated properly and this can be done on new builds or on existing concrete roof slabs.
Quad deck uses unique technology to create an energy efficient and quality insulating concrete floor and roof system.
Ideal for use in commercial and residential construction quad deck combines the strength security and reliability of reinforced concrete with the energy efficiency fast construction and comfort of insulating concrete forms.
There are a number of quinn therm roof insulation boards which will suit a warm deck flat roof construction built with a concrete deck each with different facings.
A solid slab of concrete capping the top of your house.
The climate the type of foundation whether the slab includes hydronic tubing for radiant heat and the severity of the local termite problem.
Cold roof systems are highly inadvisable as insulation from the inside will inevitably lead to the formation of condensation.
Cold roof a very bad idea.
For example the florida based company hurricane proof systems offers a 7 inch 18 centimeter slab of concrete in three layers.
Due to the continuous stone wool base the vapour barrier remains intact even during small structural movements.
It didn t take long for the framers to build and raise the exterior walls.
The concrete roof insulation waterproofing challenge commercial residential concrete roof slabs are not only expensive to build but they are also costly to maintain.
About the only out of the ordinary thing for the framers was temporarily raising the threshold of the front entry with two 2 by layers.
As long ago as 1945 the national bureau of standards reported in its bms report 103 that the.
Placing the 4 inch concrete slab was routine and after the concrete had cured framing the exterior walls could begin.
Creating a void between the old ceiling and new is better but ideally you need to eventually consider insulating the top of the concrete roof with solid insulation and a better.
Exact specifications vary but most concrete roofs are several inches thick.
Insulating a slab on grade depends on at least four factors.
Can you give me an r value.
This is then covered with a further weatherproofing layer.
The lowest insulation layer forms a uniform base for the vapour barrier.
Flat concrete roofs are generally not ventilated since the ceiling internally is generally a plaster and skim coat directly to the underside of the cold concrete.
To produce a hot roof rigid insulation is fitted outside above the weatherproofing.
The vapour barrier prevents moist air from leaking into the insulation layer.
Effective roof insulation has three or four insulation layers.
Martin holladay explains insulating a slab on grade in the energy smart details department.
