We always get asked the question “what do we need to do to be ready for the install?” so we’ve put together a brief article on how best to prepare for a Spray Foam insulation install.
On smaller projects, our team will always carry out the protective preparation work on their arrival. This includes covering the floor, doors, windows and any other items that may get over spray on them. For larger construction projects where working at height might be an issue or the building is so large and exposed that it needs significant protection, we may request your help to arrange adequate protection, although this is rare.
It’s important that the roof is weather-tight, this includes the roofing tiles in place. Some clients ask us if we can spray the foam to the breathable membrane before the roof tiles are installed. Whilst this is possible, it’s something we always insist doesn’t happen in case the membrane or foam is pushed out of place from above when the tiles are being fitted.
We respect the purpose of the roofing membrane and therefore spray the foam with a flash coat first to help retain the natural downwards drape. Once the integrity of the drape is secured, we can then layer the foam up to its final agreed thickness.
On the day(s) of install, we will require any of your staff members to stay away from the immediate installation area unless they are wearing suitable coveralls and breathing apparatus. If you have building products and tools in the installation zone, these should be moved to a safe place.
If your project is a new construction, you should aim to book in an install before any services are installed. We often find that we get called in to carry out and install as a last thought once all integral items have been installed. Whilst we can often retro-fit the Spray Foam insulation once all other items have been installed, we much prefer to have an open and clear run of things so that we can minimise our time on site whilst not having to worry about protecting intricate pipework, cables and mechanical equipment.
The surface area of where we are to spray the foam should be dry and not holding moisture and for larger spaces in cold weather, it would be ideal if the space could be heated with space heaters in the 24-hours leading up to install. This helps to heat the substrate and makes the spray foam expand much quicker. The faster it expands, the quicker we can complete the works and hand the area back to you.
We will cover any finished flooring, doors, windows and any other items that may be at risk of getting over-spray on them. On the day of install, you should avoid having other staff members of contractors working in the installation zone although we are happy for people to watch from a distance if they are interested to see how spray foam works.
Similarly to the above, you should aim to have us mobilised before your services such as pipework and electrical cabling are installed. This allows us the ability to spray-apply a seamless layer of insulation with no tricky areas to negotiate. We aren’t trying to make the process easier for us and harder for you but if you think about the stage at which you would install pre-manufactured insulation such as Rigid-PIR, we like to install at a similar stage.
Plant & Boiler Rooms often contain very large, expensive, mechanical items which are responsible for powering the property. With this in mind, it is preferred that these items are installed once we’ve completed the insulation works. Whilst we can protect and cover such items, they may impede on our accessibility around the room and make it harder and more dangerous to carry out the installation.
In instances where we feel that over-spray may damage any equipment that’s in-situ, we shall always provide protection to cover it over. The same goes with any floors, doors or windows in place. We don’t expect you to do the hard work for us but if you wanted to protect tools and materials on site before our arrival, some thin gauge plastic sheeting is usually appropriate.
