If you’re looking for an effective way to reduce heat loss and improve comfort throughout the year, spray foam insulation offers a long-lasting solution. At OS Holding, we provide professional spray foam insulation in Dublin for homeowners looking to improve energy efficiency, reduce draughts, and create a more comfortable living environment.
Every property is different, which is why we begin with a free, no-obligation site survey. We’ll assess your roof or wall construction, recommend the most suitable insulation system, and explain whether open-cell or closed-cell spray foam is the right choice for your home.
Whether you’re upgrading an older property, renovating your home, or improving a converted attic, our team delivers tailored insulation solutions designed around your property’s specific requirements.
Poor insulation can make your home uncomfortable throughout the year. Warm air escapes through the roof during winter, while excessive heat builds up during summer. This often leads to higher energy bills and rooms that never seem to reach a comfortable temperature.
Spray foam insulation creates a continuous layer of insulation that expands into gaps, joints and difficult-to-reach spaces that traditional insulation materials often miss. The result is improved thermal performance and better protection against unwanted air leakage.
Our spray foam insulation service is suitable for many residential renovation projects, including attic upgrades and roof insulation improvements. If you’re already planning a larger renovation, spray foam insulation can also be incorporated alongside our house insulation services, attic conversions, or house renovations for a more complete energy-efficiency upgrade.
Rather than recommending the same solution for every property, we assess your home’s construction first to ensure the insulation system is suitable for your roof or wall build-up.
Effective insulation reduces heat loss, helping your heating system work more efficiently. Depending on the condition of the property and existing insulation, spray foam may help reduce energy costs by up to 50%.
A properly insulated home maintains a more consistent indoor temperature, helping keep rooms warmer during winter and cooler during summer.
Unlike traditional insulation rolls or batts, spray foam expands into irregular spaces, sealing small gaps where unwanted draughts can enter.
When correctly specified and installed, spray foam can reduce the risk of condensation and mould by limiting uncontrolled air movement within the building envelope.
Every project begins with a property assessment so we can recommend the most appropriate insulation system.
Our service includes:
Not every property requires the same insulation system. Choosing the correct foam is essential for both performance and moisture management.
Open-cell spray foam is softer, more breathable and generally more cost-effective. It allows some vapour movement, making it well suited to interior applications such as attic rafters where controlled breathability is beneficial.
Closed-cell spray foam is denser and provides a stronger air and moisture barrier. It delivers a higher insulation value per inch and is typically better suited to areas exposed to damp conditions, including flat roofs and below-ground applications.
During your survey, we’ll recommend the most suitable solution for your property. Selecting the wrong type of spray foam can trap moisture rather than manage it effectively, which is why every installation begins with an assessment instead of a one-size-fits-all recommendation.
The cost of spray foam insulation depends on several factors, including:
As a general guide:
Following your free assessment, we’ll provide a detailed quotation based on your property’s specific requirements.
Choosing the right insulation contractor is about more than the installation itself. You need clear advice, quality workmanship and a team that understands how insulation fits into the wider performance of your home.
We don’t recommend the same insulation system for every property. During your survey, we assess your roof or wall construction before advising whether open-cell or closed-cell spray foam is the right solution.

Not always. The correct insulation depends on your roof construction, ventilation and overall building design. We assess your property before recommending spray foam because using the wrong system may trap moisture rather than manage it effectively.
Open-cell spray foam is softer, more breathable and typically used in attic roof spaces where some vapour permeability is beneficial. Closed-cell spray foam is denser, offers a higher insulation value and provides a stronger air and moisture barrier, making it suitable for areas exposed to damp conditions.
Costs vary depending on the foam type, the area being insulated and accessibility. As a general guide, whole-home installations typically range from €25–€60 per m², while attic installations generally range from €50–€100 per m². We provide an exact quotation after your free assessment.
