Warehouses & Factories

These structures usually have metal, cement fibre or asbestos roof sheeting which are often corrugated to allow channels for rain water to escape. Without insulation these materials are great thermal conductors and are highly susceptible to temperature extremes, condensation and poor energy efficiency.

Pre-manufactured insulation materials, such as PIR, lack the flexibility to sufficiently insulate corrugated structures for the long term. Spray foam solves these issues when spray-applied as a liquid, expanding into all voids to provide seamless insulation coverage.

We recommend a Closed-Cell formula, such as ThermoFoam CC-2000 to prolong the life of your corrugated roof. In addition to being a high performance insulator Closed-Cell foam will help to bind and seal any damaged or degraded panels to limit moisture ingress.

Insulation - 50mm CC-2000 Spray Foam

When a building suffers from condensation, you may be impacted financially through stock damage and liability to personnel, equipment and furniture.

For property experiencing this problem an application of 15-20mm will resolve the issue and completely eliminate all future condensation.

Over time, roofs can start to degrade where cracks may appear or the bolts and gaskets that hold roofing sheets together start to fail.

50mm of Closed-cell spray foam offers a solution which helps to stabilise the roofing sheets by bonding all joints and seams to create a single membrane.

We regularly come across such buildings where a pre-manufactured insulation, such as PIR, has been used and it’s always sad to see the costly impact when these solutions fail the test of time.

When the time comes to upgrade and replace existing insulation, a property survey will help us determine the options to create the most effective thermal envelope for the long term.

The Takeaway
Although cost should always be considered, the insulation choice that you make is imperative in achieving optimal performance. Warehouses and factories are rarely small in size and the disruption and downtime you might experience throughout the installation makes the choice of insulation an important factor.

It’s not just the performance of spray foam, it’s the speed of application that can truly help to minimalise down-time during install and this should help form a part of any cost-benefit analysis when selecting the right option for your property.

Open-Cell vs Closed-Cell
(In moisture rich environments)

Although we install both open and closed-cell products, not all spray foams are created equal, therefore we are always careful to respect the application uses for both products in achieving the correct install for your building.

Open Cell is a low density sponge like foam, making it an effective barrier against noise transmission and adds good thermal performance to a building.

When used in areas that are susceptible to moisture intrusion, Open Cell foam will absorb this moisture which can create issues within the building or structure it is applied to.

To overcome this, we always recommend an application of Closed Cell foam for buildings that have metal, asbestos or cement roofs. These are commonly held together by bolts and gaskets, which when rusted or broken, act as the first entry point for moisture.

Closed Cell is a high density rigid foam, that acts as a very good vapour barrier. It helps to bind all aspects of a roof substrate to prevent the degradation or loosening of bolt fixings and adds structural integrity.

As little as 25mm of Closed Cell insulation will eliminate condensation whilst an application of 50mm will provide exceptional thermal performance. Both depths offer strong adhesion to the substrate to future-proof its integrity.

The quality of the install was very good and I am pleased to report that it has solved the job this winter in eliminating roof condensation. We have noticed that the building is a little warmer in winter as well and look forward to a cooler summer!
