The best solution
Sprayfoam compared to other insulation materials
1. High insulation value
If you want to compare insulation materials, it is important to look at the Lambda value. The lambda value is the degree of thermal conductivity of a material. The higher the value, the better the heat is conducted. So for home insulation, a low value is better, because then little heat is lost.
Below are some common insulation materials, each with their insulation value. The lower, the better.
- NRockwool: 0,031 – 0,044
- NEPS (polystyrene): 0,031 – 0,045
- NXPS: 0,028 – 0,038
- NPIR: 0,021 – 0,026
- NCork: 0,038 – 0,040

Even within each category, each material – or brand – has its own specific insulation value. For example, the Lambda value of our Froth-Pak
is 0.022 W/mK, making this insulation foam the best within the polyurethane (PUR) category. Linked to this insulation value (Lambda) is the thickness of the material. The lower the Lambda value, and therefore the better it insulates, the less thickness you need to obtain the same
result as with another insulation material. For example, with rock wool, the insulation layer needs to be thicker than with PUR to get the same result.
Once you know the Lambda value of the insulation material, and you know the thicknesse, you can calculate the R-value. The R-value for insulation is a way to measure how much resistance the insulation has to heat flow. The higher the R-value, the more the resistance and the better the material is at insulating a home. Generally, insulation materials with higher R-values cost more when compared to those with lower R-values.
Thermal phase shift and inertia
We’ve seen previously both notions of lambda and R-value, they indicate the quantity of energy that goes through the insulation material, thermal phase shift, this time, indicate how long it should take to this energy to go through the insulation material. In other words, it is the ability of a material to slow down the energy transfer.
In a traditional construction, the phase shift plays a less important role because most of the materials used have a natural high density and thus possess thermal inertia. Consequently, this results in an increase in the phase shift duration.
But in modern style constructions, the materials used are often lighter, and at this moment it is mandatory to increase their thickness in order to enhance the thermal phase shift.
On an average 15 cm to 20 cm, PU Foam has a natural thermal shift of 6 hours.
2. Watertight
It is important to know that there are two types of PUR foam. Open-celled, and closed-celled. In case of open-celled, moisture can be absorbed into the foam, so we want to avoid this. Therefore it is better to opt for closed-cell foam such as Froth-Pak. As the name closed-celled indicates, this insulation foam is chemically composed of millions of individually sealed cells into which moisture cannot enter.
When moisture enters the building envelope, it can affect the insulation’s performance, reducing its ability to resist heat transfer. This leads to higher heating and cooling loads, increased energy usage, and elevated utility costs. By using watertight materials, the insulation remains effective, supporting optimal energy efficiency and thermal comfort within the building.

3. Airtight
Good airtightness can raise the energy performance of a building, construction or industrial product by up to 15%. The Fomicom sprayfoams are two-component PU foams that are made up of [at least 95%] closed cells ensuring perfect airtightness. After all, good insulation is only as reliable as its weakest link. To rule out energy loss, everything must be perfectly sealed. The simple Froth-Pak sprayfoam system allows the placing of seamless insulation in a controlled way whereby it is possible to dose as much as you want and waste is reduced to a minimum..
In this video we show the difference in airtightness between the much used mineral wool on the one hand, and polyurethane sprayfoam on the other hand. Quite impressive, right?
4. Fast and easy
The Fomicom foamkits are very easy to use. Any professional or company can use it wherever they want, and when they want. After heating the cilinders for some hours to at least 24°C, the hoses are connected to the cilinders. The valves can now be opened completely to supply an equal flow of both components. For first use, or after a few days of standstill you must flush the system. To do so, simply pull the trigger full force in a waste bin for a couple of seconds. Clean the gun with PU cleaner and apply a layer of vaseline to extend the lifetime of the gun. Click a nozzle to the gun, and spray a sample.

COLD BRIDGES
What is a thermal or cold bridge?
A common mistake is to use inferior insulation materials at joints between 2 building components. Foaming up seams and cracks, for example, using single-component PU foam from the hardware store. As mentioned above, it does not have the same insulation value and airtightness as, for example, our Froth-Pak closed-cell insulation foam. If you use PUR or PIR boards for wall and roof insulation, it is better to fill such gaps, seams or connections with a material that has the same quality in terms of insulation value and airtightness.
When building a house, there are plenty of potential building nodes or thermal bridges that need to be addressed. The video below highlights some of these potential thermal bridges.

1.
CONNECTION BETWEEN
WALL AND ROOF
INSULATION
Avoid to connect two building elements (e.g. wall & roof) with open cell sprayfoam cans you find in the retail construction market. Not only the insulation value is inferior, also on airtightness there’s a massive difference with our closed cell foams.


2.
CONDENSATION
ON METAL
SUPPORT BEAM
Metal is sensitive to temperature fluctuations. If a poutrel is used between an indoor and outdoor transition, condensation may occur on the metal here due to the temperature difference. This moisture can cause odour or mould in the long term. With a 2-3 cm layer on the poutrel, you ensure that no condensation can occur on the metal.

ROOF INSULATION
Roof and attic insulation
Insulating a roof or attic greatly contributes to the energy efficiency of a home. By properly insulating the roof, you not only save in heating costs, you also increase the overall perceived comfort of the home. In summer, the house heats up less through the roof, and in winter you can keep the stoked heat inside.
The Fomicom foam kits are suitable as roof and attic insulation when a post-insulation company (such as Isotrie, Isolair,…) cannot offer a suitable solution with their PUR high-pressure spray machine..
Reasons for this may be:
- area too small (e.g. home extension, renovation)
- hard to reach places
- when it concerns highly technical insulation with many possible thermal bridges
- when the room cannot be completely emptied

The advantage of the Froth-Pak system is that there is no formation of aerosols, and there is no annoying atomisation. The insulation foam is inert and durable considering it will continue to serve the entire life of the building. Meanwhile, PUR foams can also be recycled in several ways. Either they are reused in new insulation materials, but chemical recycling is also possible.
1.
SMALL SURFACES
In case of renovation it is quite common that there is only a small surface that needs to be insulated. Therefore it is very difficult to find a company willing to do this small surface with their high pressure machine. Understandable as their system is best suited for insulating large areas.
Sprayfoam kits, such as Froth-Pak, allow you to insulate the surface without having to depend on a third party. You decide wherever and whenever you use the high-quality insulation sprayfoam kits.


2.
FOR HARD TO REACH
PLACES
Foamkits are low pressure system that can be used without any machine. This makes them ideal to spray in hard to reach places.
They allow you to work in detail without any waste. Depending on your needs you can choose the thickness of your insulation layer. Also, you create a seamless cover that is completely airtight and watertight.
3.
TECHNICAL INSULATION
Insulation helps to increase the building efficiency and reduce the energy loss. Unfortunately a lot of energy is lost because of some thermal bridges, for example the connection between the wall and roof insulation. Foamkits make it easy to focus on these weaknesses in a building.

WALL INSULATION
Seamless, airtight & watertight insulation
You can determine the thickness of the foam layer yourself. If you mainly want to improve airtightness, a 2-3 cm layer will suffice. To insulate properly, a thicker layer is required, depending on the intended R-value. A first layer serves as an adhesive layer. In a volatile motion, you ‘mist’ the insulation foam onto the wall so that parts of the surface are still visible through the insulation foam. You then let this cure for about 10 minutes, before applying a thicker layer of several centimetres. It is recommended to build up in layers of 3-4 cm, to avoid the foam sagging when applying a thick layer.

Insulation foam kits are not used to spray large areas so they are usually not used in new construction. In renovation, on the other hand, there is often a single wall, or a particular room that needs to be insulated. This is where PUR foam kits offer an ideal solution. In no time, you can insulate the room airtight and watertight.
The advantage of the Froth-Pak system is that there is no formation of aerosols, and there is no annoying atomisation. The insulation foam is inert and durable considering it will continue to serve the entire life of the building. Meanwhile, PUR foams can also be recycled in several ways.

LOW PRESSURE
= NO AEROSOL FORMATION
Froth-Pak is a low-pressure system so there is little to no aerosol formation. This makes it suitable for indoor or outdoor application. Only requirement is that there is no tight wind at the time of outdoor application. For outdoor use, the foam needs to be protected from UV-light so a cladding or protective coating or painting is necessary. After applying an initial bonding layer, it can be sprayed in 3-4 cm layers to the desired thickness.
The result is air- and watertight insulation in no time.

BASEMENT INSULATION
Energy efficiency at its best
Basement insulation is an important step in creating a comfortable and energy-efficient home. By using sprayed insulation foam in this process, you can seamlessly and airtightly seal off the basement space from the occupied area above it. The cool nature of the cellar can thus be maintained, but the cold and/or heat can no longer be exchanged with the living area above it.
A basement is often a damp room. The insulation foam provides a moisture barrier that helps prevent water infiltration. Due to the high humidity in basements, insulation foam can prevent mould, rot and other water-related problems from occurring. Before applying the insulation, the walls must be dry to ensure good adhesion.
Another advantage of insulation foam is its durability. Properly applied, it can last for decades without any reduction i n quality, unlike other insulation materials that can collapse over time, absorb moisture, degrade,…. The longevity of sprayed PUR ensures that you can enjoy its benefits for years to come, making it a cost-effective choice in the l ong run.


Before

After
1.
ROOF ONLY
Insulating the ceiling will, on the one hand, ensure that the cold in the basement cannot rise into the occupied, and heated, part of the house. Also, in the heated part of the house, it will ensure a pleasantly warm floor that is not cooled by the basement below. Insulating the basement ceiling is very energy efficient in the long run. Installing the insulation once will provide years of pressure on heating costs.


2.
ROOF AND WALLS
When the aim is to achieve as constant a temperature as possible, it is advisable to insulate both the ceiling and walls. This will ensure a v ery constant temperature throughout the year. Similarly, if the basement area is very humid, it may be opted to foam coat both walls and ceiling.
3.
CRAWLSPACE
Insulating the ceiling of the crawl space will, on the one hand, ensure that the cold in the basement cannot rise into the occupied, and heated, part of the house. Also, in the heated part of the house, it will ensure a pleasantly warm floor that is not cooled by the underlying crawl space. Insulating the ceiling of the crawl basement is very energy efficient in the long run. Installing the insulation once will reduce heating costs for years.

WINDOW INSULATION
Airtight sealing of windows
With deep window frames, it can be quite a task to foam up the entire depth of the frame. With the Fomicom foam sets, you can get the job done in no time. An extension piece can be pushed onto the nozzle which allows you to inject foam to the back of the window frame.

1.
AIRTIGHT SEALING
When sealing windows or doors, a basic expanding can foam is usually used. An airtight tape is then put on top of this given that the one component expanding foam has no airtight qualities. With the Fomicom insulation sets, you can do both in one move. Fix the window, and make it airtight. In about two minutes, the foam is cured and the window or door is securely fixed.


2.
DEEP FRAMES
Deep window frames completely filled and made airtight in less than 5 minutes? Challenge accepted. In no time at all, the deep window frame can be filled airtight with insulation foam. To reach the back of the frame, an attachment piece can be connected to the nozzle of e.g. 20-30cm. The foam expands from the back to the front, meanwhile pushing its way up.
