The traditional insulators are usually glass slabs, polystyrene sheets, or minerals. However, these are less potent in comparison to spray foam insulators. The traditional methods are less costly, but less effective as well.

Can this be installed without a professional?

Spray on foam insulation essentially needs a professional. While installing it, harmful fumes released can easily cause damage to a building’s structure. Incorrect installation can further harm an establishment as well. Expanding foam is capable of exerting pressure on a building’s inner structure.

There have been cases of wrong installation where a building has collapsed due to incorrect installation on ceilings. So, employing a professional is of utmost importance here.

Why opt for foam insulation at home?

Spray foams are of two types – closed and open. These are suitable for different home needs and budgets. Usually people don’t insulate their lofts since they tend to keep their things there. Moreover, traditional methods require a thickness of 270mm for loft insulations.

However, foam insulation requires just 100mm of spray thickness to serve this purpose. According to researches done by the National Insulation Association in the UK, spray foam is way better as an insulator than mineral wood. It provides the same effect with less amount.

Often spray foams settle in hard forms to reinforce the roofs that have cavities or nail fatigue. Only a discussion with a professional can help one decide whether a building needs treatment for solid walls or cavity walls.

Is it water-resistant?

Some of the foam insulators are breathable yet waterproof. These are exceptionally useful for all rain-prone areas in the UK. In addition, they can also serve a greater purpose for areas that experience floods as well.

What are the costs involved?

Insulation companies first check the building, its walls, floors, ceilings etc and then provide their service. Some of the insulation companies provide heavy discounts on their first order.

In the UK, some of these organisations even check the eligibility of a customer on ECO Scheme. Often government benefits are there for houses which need insulation.

The cost entirely depends as per the thickness of the foam installed and the surface area that needs sheathing. The NIA has standardised the per square meter price which ranges from 20 to 50 pounds.

Thin layers cost less while thicken insulation costs more. Closed cell insulation is costlier than open cell.

The service charge varies depending on the following:

• Difficulty in installation.
• Roof type; its present condition and damages.
• Repair work if needed, etc.

What are the types of foam spray insulation?

• Closed cell foam spray: It settles into rigid form. It helps in providing support to the building’s inner structure. This is most useful for structures that need repair and reinforcements. This hardened form of foam slows down heat movement with its gas pockets. But, it obstructs moisture, so, it is vital to have the room perfectly ventilated to prevent condensation build up.
• Open cell foam spray: This foam is compressible with hand and is not as dense. It is not suitable for structural support. But it is effective for sound insulation. It essentially blocks airflow and moisture passes through easily avoiding chances of condensation.

How to choose the professionals for installation?

According to the recommendations by National Insulation Association UK, foam spray insulation must be done by a professional. All experts are trained and assessed by the British Board of Agreement. The British Board of Agreement certifies each company and their experts on the basis of their competence.

So, before availing their services it is essential to check their competence and certification.

Is surveying vital?

Every professional team must execute a survey of the building before starting the installation. U-value evaluation and risk calculation are indispensable in these cases. The professionals also hold expertise with software that helps in this process.

It used to be that building “insulation” evoked images of rolls of fiberglass batting material in either pink or white/yellowish color. Since the late 1930s, long strips of fiberglass batting have been cut to fit between wall studs and sandwiched between the exterior wall and the sheetrock interior.

Fiberglass provided far superior (and safer) building insulation than had been used in construction for centuries. But it was, and is not without a significant health risk caused from inhaling the small fiberglass particles that can break free from the batting during handling. Protective mask, gloves, goggles, and clothing were standard safety equipment when installing fiberglass insulation.

And despite its insulating effectiveness, fiberglass does not provide a truly good vapor and air barrier if not properly installed.

Many of today’s commercial construction projects are being insulated with foam products that are providing greater insulation and other intrusion resistance than fiberglass batting. Let’s explore some of the history and uses of foam insulation.

The short story

Spray foam insulation is polyurethane product that was developed in 1937 by the German industrial chemist, Otto Bayer. It was brought to the United States where it was used in military and aviation projects in the mid-1940s.

After the war, the auto industry began using polyurethane polymers in car bodies and the housing industry began using it on a limited basis for insulating homes. By the 1970s, technology had improved the application and affordability of spray insulation for use in the construction industry.

Today’s spray foam insulation products provide greater energy efficiency and are achieving increasingly improved “green ratings.” This insulation is utilized in many housing and commercial construction projects around the world.

R-value ratings, Open Cell and Closed Cell foam insulation

Insulation has an R-value rating, “a measure of resistance to heat flow through a given thickness.” Generally, the higher the R-value, the greater the heat flow resistance will be.Spray foam insulation has higher R-value ratings than does fiberglass insulation.

Modern spray insulation used in construction is usually one of two types: “Open Cell” or “Closed Cell” foam.

• Open Cell foam is comprised of tiny foam cells that are not fully closed. Air fills the “open” space inside the material. Open Cell foam has an R-value of 3.4 to 4.5 per inch.

Open Cell insulation is a very effective sound barrier (nearly twice the sound resistance as Closed Cell foam).

• Closed Cell foam is comprised of fully closed cells densely packed together and filled with gas, enabling the foam to rise and expand. Closed Cell foam has an R-value of 5.4 to 7.2 per inch.

Closed Cell provides superior insulation and because of its greater cellular density it provides structural reinforcement to insulated surfaces.

Benefits of spray insulation

This insulation offers a number of unique benefits when used in commercial and residential construction:

• This insulation has no food value meaning that the foam is of no food interest to destructive insects and rodents.
• Bacteria and fungal growth cannot develop on spray foam insulation because it is an inert substance.
• Applied in liquid form, spray foam insulation expands and conforms to all open spaces creating a “continued thermal envelope” that effectively seals off leaks and gaps and prevents insects and vermin from entering.
• Spray foam insulation adheres to any clean and dry surface, will not shrink, settle, or disintegrate.

Value in commercial construction

Spray foam insulation is more expensive to install than traditional fiberglass insulation. However, spray foam offers considerable sound and weather insulation benefits to nearly any imaginable construction application.

Its initial expense will be offset by its durability (80+ years), its ability to fill even the smallest areas that fiberglass can’t even reach, and provide higher energy efficiency thus reducing energy expenses.

With the increasing focus on energy efficiency, it is highly likely that spray foam insulation will continue to gain in use in both the housing and commercial construction industries.
