Roofing insulation adhesives
Paramelt offers Dynol™ 1-component PU adhesives suitable for virtually all types of insulation currently in use, with or without coating, as well as for a wide range of substrates.
Benefits of adhesive use
Increasing energy efficiency demands in the construction sector are driving the requirement for improved building insulation across the board, including the contribution from the roof structure. As a result the insulation materials being employed in flat roofing structure are getting thicker to increase the R-value and reduce heat loss.
Adhesive bonding of the insulation material has a number of significant advantages. In contrast to mechanical fixings, the thickness of the insulation does not have a significant impact on the ease of application, whereas mechanical fixings are beginning to reach their practical limitations. In addition, the use of mechanical fixings inherently lead to the creation of cold-bridges across the insulating layer, thus reducing its thermal efficiency.
Additionally, adhesives inherently provide superior anchorage for the insulation, since the material is bonded across a much larger surface area rather than a limited number of fixing points. As a result, strong winds present no problem due to better distribution of forces over the roof area.
The use of adhesives in place of mechanical fixings also brings a number of contractor related benefits. For example, the adhesive bonding of the insulation is far quicker to complete, when compared with the time required for drilling and fixing with mechanical fasteners. In addition, the noise nuisance to occupants of a building when the roof is being renewed, is much less when the adhesive bonding method is used.

Our range of adhesives for roofing insulation:
This 1K polyurethane (ready to use) adhesive is a solvent-free, moisture curing product and is suitable for virtually all types of insulation materials currently in use, as well as for a wide range of substrates.
These substrates can be coated profiled metal, metal sheeting, bituminous covering, concrete and wooden sections such as underlayment, plywood and chipboard. Insulation materials can be expanded or extruded polystyrene, polyurethane, poly(isocyanate), mineral wool or expanded perlite.
Paramelt’s Dynol roof insulation adhesives are highly foaming products, specifically designed to allow the levelling out of irregularities up to 5mm in size, between the substrate and the insulation material.
The adhesive is permanently elastic and as a result is readily able to absorb significant movements in the roof structure due to thermal or mechanical influences.
Insulation adhesive properties
The adhesive is permanently elastic and as a result is readily able to absorb significant movements in the roof structure due to thermal or mechanical influences. The following properties of the adhesive are important.
- Gap-filling (foaming) properties
- Initial strength
