What roof panels with integrated insulation?Solutions
Batirama.com 07/20/20171Synonyms of time, surface, productivity and profitability, roofing panels with integrated insulation still seek their market.Not for long.
Competitors of traditional solutions, roofing panels with integrated insulation have trouble drilling.These coverage supports which rhyme with profitability and secure implementation have been impacted by a building conjuncture so far at La Traine.
But today, "considered rapid solutions, they find a certain interest with craftsmen and traders," notes Gilles Rattin, commercial director of Quickciel.And for good reason.These thermal insulation processes from outside the roof combine the advantages.
Experienced box or sandwich panel
Admittedly, unlike a sarking which brings thermal performance to fitted attic, roofing panels with integrated insulation are a heavy renovation.
But they remain the only processes to provide a three solution into one by integrating decorative subface, insulating layer and cover support.With two major product families: on the one hand, experienced boxes "who, by a traditional solution, represent 80 % of our sales, informs David Valente, commercial director of the undisputed leader of this technique, Unilin Insulation.
The rest of this market being devolved to sandwich panels.For Michel Kratz, President of Euromac 2, “These panels with integrated insulation remain the most successful solution to remove thermal bridges with rapid delivery of the room, unlike traditional roof insulation with important implementation deadlines anddelicate process ".
More brakes to lift
However, these solutions find it difficult to pierce."They suffer from an expensive image, when they should not be more expensive than a traditional process," notes David Valente.
"Many companies lose markets because they are too greedy on the margin applied to these materials when it is better that they highlight the workforce.It’s their know-how!"Adds Gilles Rattin.And for everyone, roofers must take the plunge today.
Especially since in five years, "evolution towards these products with high thermal resistance will be radical", augurs Michel Kratz."They will be an answer for more efficient and more economical buildings", and in all sloping roof markets.
Do you need a under-ownership screen?
Experienced boxes do not fulfill the sub-roofing screen function.It is therefore imperative to refer to the technical notices and the associated covers (series 40) to the boxes in order to verify whether their presence is necessary or not.
Solutions eligible for different aids
The thermal performance required for obtaining the Tax Credit Energy Transition (CITE) for roofing crawlers and attic ceilings must present a index r greater than or equal to 6 m2.K/W.A performance achieved by roofing panels with integrated insulation of the blow also eligible for zero-rate eco-loan and energy saving certificates.
Roof or sarking panels?
The roof panels adapt to new and renovation, when the sarking mainly covers the roofs to renovate.But each of these thermal insulation processes from the outside find its applications.
So whatever the state of the frame, but if the tiles are to be changed and the ceiling to be redone, the roof panels with integrated insulation are the most relevant answer.
Conversely, if the frame like the ceiling do not need to be renovated, the sarking which consists in installing successive layers of insulating elements on a traditional frame, becomes more relevant.
Regulations and approvals
Integrated insulation roofing panels must be subject to technical advice to which must be referred to.Likewise, those stamped Acermi (Association for the certification of insulating materials) have certified performance from a point of view of their thermal conductivity (λ) and thermal resistance (R) to oppose the transfer of heat.
Solution 1: experienced boxes, the most widespread
© Unilin Insulation
This thermal insulation system from the roof exterior covers 80 % of the roof panel market with integrated insulation.
To keep an apparent frame, create living space or save square meters quickly, these roof panels with integrated insulation adapt to all sloping roof projects.
Insulating system cover support on ventilated air blade, a experienced box consists of fixed solid wood rafters and treated in the factory, (two or three depending on the industrialists) solidarity with an underside panel that constitutes the ceiling.The insulation that completes this system is according to industrialists in mineral wool, PSE, PU ...
Direct fixation on the frame
The experienced boxes attach directly to the frame, on a number of reduced breakdowns.They replace traditional rafters.With the key substantial savings on the roofing installation cost.Especially since in a single operation, the experienced boxes make it possible to carry out the insulation, the renovation of the roof and the interior decoration of the ceiling in a wide choice of decorative finishes.
Thus, this process of thermal insulation from the outside ensures surface gain and a high thermal resistance (at least R6) while remaining the only process of roof panels to provide effective technical responses for the treatment of singular points.
Solution 2: Sandwich panels, for continuous insulation
Sandwich panels guarantee the absence of thermal bridges and air tightness under all types of covering coating.
With sandwich panels, thermal insulation is taken between cover and interior facings, all by constituting a single element.Thus, the living volume is optimized in particular in terms of attic when the old rafters are deleted.
It does not suffer from any thermal bridge and the ventilation of the coverage is ensured.Once the old building is offheavy, it is again out of water and out of air in 24 hours, without requiring stain or paint.The remaining apparent frame, the structure is valued in new and renovation.
High mechanical resistance
These sandwich panels are also available with integrated metal rafters for all types of slope.Self -supporting, they display a high mechanical resistance, hence an interest in mountain roofs, and the possibility of making long lengths on request.
And at a time when electricity should finally be widespread these solutions are also compatible with a photovoltaic installation.
