OVERVIEW AND CONDITIONS
Is PUR foam the right solution here?
The roof protects the building against large temperature changes, wind and precipitation. The insulation must remain continuous at rafters, windows, chimneys, parapets and installation penetrations.
Good project begins with an assessment of the structure and conditions, not just the square footage. The product, thickness and method of protection of the layer should be described before work begins.
KEY DECISIONS
What do you need to confirm?
01
Separation state
Substrate, existing layers, humidity and places to be repaired.
02
System selection
Type of foam and thickness resulting from the design and expected effect.
03
Layer protection
The method of protecting foam and reception from the next stage of construction.
BENEFITS OF WELL-DESIGNED SPRAY INSULATION
What can be achieved in the correct execution?
The effect depends on the complete building element system, material parameters, surface preparation and application quality.
01
Continuous insulation on complex sheet geometry
Continuity must also be checked on connections to adjacent bulkheads.
02
Exact execution of details on rafters and crossings
Corners, transitions, installations and restricted access areas require the most attention.
03
Possibility to select a system for slanting or technical roof
The correct effect depends on the product, the thickness and the conditions of the application.
04
Organisation of work tailored to the scope of modernisation
Confirm the scope of work and the final inspection procedure in the quotation before spraying begins.
PLACE OF APPLICATION
Where is this solution being considered?
The scope should be described by a specific plane and its layers. The same name of a room may mean a completely different structure and working conditions.
- sloping roofs from the attic side
- flat roofs and rhizomes
- area over technical objects
- details by windows, chimneys and atts
PRODUCT SELECTION
What kind of foam to choose?
Open-cell foam is often considered for a wooden roof, and a closed-cell system for a technical roof or in a zone exposed to moisture. It is the entire arrangement of layers that is decisive, not just the shape of the roof.
Border condition: The foam does not replace roof repairs, treatments or systemic protection against water and UV radiation.
STANDARD OF IMPLEMENTATION
From recognition to isolation reception
Each stage reduces a different risk. The layer should not be covered until the agreed details have been checked.
01
Recognition
Construction, humidity, access, installations, existing layers and expected effect.
02
Preparation
Stable, clean and properly dry substrate and environmental protection.
03
Application
Controlled spray parameters, layer work and current continuity control.
04
Over.
Check details, agreed thickness and documentation before further work.
IMPLEMENTING RISK
What's not to miss?
The most common problems result from rushing the preparation or covering the insulation without inspecting it. Discuss these points with the installer.
- no diagnosis of leaks before spray
- moisture closure in the structure
- discontinuity at windows and installation transitions
- lack of protection of foam from UV in external application
EVALUATION PREPARATION
What should I give the contractor before the first conversation?
A few specific pieces of information are enough to distinguish a simple project from an object that requires an inspection or additional documentation.
01
Location and time limit
Locality, stage of construction and planned date of construction and insulation cover.
02
Photos of the whole surface
View of partitions, substrates, difficult details, installations and places with limited access.
03
Actual metres
Surface area of the planes intended for spraying, not just the usable surface.
04
Design and Layers
Separation section, type of structure, existing insulation and expected effect.

FAQ
01
Is PUR foam suitable for this use?
Open-cell foam is often considered for a wooden roof, and a closed-cell system for a technical roof or in a zone exposed to moisture. It is the entire arrangement of layers that is decisive, not just the shape of the roof. The final decision should be confirmed based on the design, substrate condition and documentation of the specific system.
02
What do you need to check before you spray?
The key considerations are the watertightness of the roof covering, the condition of the substrate, moisture paths and how the foam will be protected. The installer should also confirm the temperature, access and protection of components that will remain free of foam.
03
What does PUR foam replace in this bulkhead?
The foam does not replace roof repairs, treatments or systemic protection against water and UV radiation.
04
What to send to the preliminary valuation?
Provide the city, approximate spray application area, building type and planned date. Include photos of the entire building element, details, installations and existing layers.
05
What is the final price?
From the surface and thickness of the layer, type of system, geometry, condition of the substrate, access, number of protections, required foam protection and organisation of work on the facility.
