How to Install Insulation in Ceiling - The Easy Way

If you own your own home, then the chances are that you have asked the question of how to install insulation in ceiling. You may also have asked whether there are advantages to doing this.

Spray foam insulation undoubtedly has advantages, including the following:

  • It will increase your home’s energy efficiency.
  • Spray foam will form a seal against thermal weak spots.
  • It is resistant to rot from moisture, and because of this, it can be used in ceilings, down walls, and right down to the ground.

There are some points that you should take into consideration when installing insulation in ceilings, such as:

  • Cost: Spray foam insulation is relatively pricey, so you should only opt for this choice if you plan to stay in your home for many years.
  • Existing insulation: Any existing insulation will need to be removed before you install insulation in ceilings.
  • Ventilation: Things like power points must be removed and sealed shut.
  • Windows: If the windows are single pane glass or draughty, the effect of the spray insulation foam will be only minimal.
  • Be meticulous: For the spray foam to be effective, you must make sure to take your time, fill every gap in uneven areas, such as roof framing, or over doors and windows.
  • Time: If you stop for longer than 30 seconds the nozzle will clog and you will need to put on a new one.
  • Temperature: The air temperature must stay between 75 – 85 degrees.

What to Wear

It is important that you follow the instructions. Read them beforehand, and have all your clothing ready.

Spray foam is very sticky, so you will need disposable overalls with a hood. Gloves are essential, as is a face mask and eye protection.

How To Install Insulation In Ceilings:

  1. Check and attach air baffles: These are also called vents. They direct air flow through the ceiling space. They help to moderate the temperature in the attic and protect against water condensation damage. They should be stapled to the underside of the eaves before you spray your foam insulation.
  2. Choose your spray foam insulation: Make sure you select a good quality spray foam. Your foam should come with a chart giving you measurements and depths that you should adhere to. You will find all this important information here.
  3. Fill those gaps: It is important that you take your time, and fill all the gaps between the rafters, so that there are no spaces for air to circulate outside. If you pay attention this even before you start with your spray foam insulation, you will save yourself having to repeat the process. Having done it correctly the first time, you will avoid heating costs from a roof which does not retain the heat in cold weather.
  4. Spray your foam: Make sure that you are completely covered before you start. Applying spray foam is a messy business so keep your eyes covered and your gloves on. The foam will spread and expand, so use smooth movements, keeping the foam to the required depth.
  5. Allow It To Dry: After you have applied your spray foam, you should let it dry completely before trimming off any excess, or overflow areas.
  6. Never hire a ‘cowboy’: If you feel that the process is just too daunting, then you should avoid ‘cowboy’ outfits. Our experts at HomeLogic will be glad to help you.

Common Problems When Applying Spray Foam

  • Chemicals not mixed correctly: You will notice that the foam starts to pull away from the surface. This may also cause some lingering smells which are unpleasant, so be sure to mix the chemicals as explained in the instructions.
  • Rushing and leaving gaps: Take your time, do a thorough job, to save having to repeat the process.
  • Check the thickness: There’s a reason for the depth to be what the instructions say! Experts have done research and given you the best depth to apply your spray foam insulation.
  • The weather: take into account the outside temperatures, otherwise you will find that the foam does not cure correctly. Stick to the manufacturers recommendations, even if it means putting the work off for a week.

Potential Health Hassles

Simply because you are mixing chemicals, there may be a reaction in someone who has respiratory problems.

The lingering smell of chemicals may adversely affect breathing, so it is essential that you follow the directions.

It is also important that you pay attention to what you wear – this is not a job that can be done in shorts and a t-shirt!

Installing Spray Foam Insulation In Ceiling: Why Do It?

Reason No.1: It Protects Against Airborne Pollutants

There are no toxins in spray foam, and it won’t ‘off-gas’ or break down to release harmful contaminants into the air like older, more traditional insulation products.

Instead, the seal will keep out pollutants and allergens. This will leave the air in your home cleaner and fresher, without pollen, car fumes or smoke from the outside coming in.

Reason No.2: It Protects Against Pests

With no little gaps to wriggle through, and no yummy insulation to eat, pests such as mice, rats and insects, will no longer be able to find their way in to your home.

The need for additional pest prevention measures will be negated, and there will no longer be any worry about hygiene.

Reason No.3: It Keeps Noise Out… And In

Whilst not quite the professional soundproofing pads you’ll have seen in cinemas and recording studios, lab testing has shown spray foam insulation blocks up to 40% of noise in the area insulated.

This means that not only can you prevent car horns, aeroplane noise and conversations coming in from outside, you’ll also find your music and chats don’t travel any further than they need to.

The soundproofing properties of foam enhance your quality of living considerably. Besides, who can put a price on a happy, comfy, quiet life? That’s something we all deserve.

Reason No.4: It Offers Guaranteed Return On Investment

‘ROI’ or ‘Return On Investment’ is a phrase normally used for business purposes, and refers to how much an initial investment makes back over a period of time.

This phrase isn’t particularly used domestically, but the more cost-conscious amongst us should absolutely consider it. ROI need not be just in financial terms; it can also refer to a tangible benefit in the household as well

In fact, there’s an insulation product that has full financial ROI within just a period of three years, due to its superior efficacy in contrast to traditional methods, such as fibreglass.

Spray foam insulation is a multi-functional insulation chemical product that is applied directly onto, or injected into ceilings, walls and floors, and their cavities or crawl spaces.

This multi-purpose product has a chemical make-up that results in a complete seal against the onslaught of the elements. This creates a thermal barrier, stopping hot air from leaking out, and preventing cold air from coming in. The result is an insulation safeguard more effective than any other.

There are no gaps between insulation panels, or sagging spots that enable cooler areas to occur. Instead, the spray foam solution fills the space around it, before drying out and solidifying; completely filling any spare nooks and crannies.

As a result, properties with spray foam insulation installed are noticeably warmer – and it’s the market leading insulation solution in colder countries, such as Canada, Sweden and Norway-thus attesting to its ability to curb cold spots.

In the UK, whilst we love to bemoan the rain, we don’t suffer with quite the same extremes of temperature, and so it’s even easier to block out cold air, rain and snow.

Spray Foam: The Solution To Soaring Bills

Needless to say, the UK has some of the most expensive energy providers in the world. Yet the installation of spray foam insulation means that your property’s energy demands decrease, as less heating and cooling is required.

Those with spray foam insulation already installed in their homes report saving up to 40% on their heating bills – a hefty discount!

Based on this and the average household energy bill in the UK, the installation of spray foam insulation will have delivered a full ROI in monetary terms in a period of less than three years.

There are other tangible benefits to be considered that also make up the investment’s return. After all, sealing your home off doesn’t just protect it against weather and temperature-it prevent pests from entering as well.
