Spray Foam Insulation: Questions to Ask Before Letting Anyone Near Your Walls in Wales
If you’re thinking about improving your home’s warmth and energy efficiency, spray foam insulation is on everyone’s lips these days. But before you let anyone start spraying the inside of your walls, loft or even roof, there are some important questions you’ll want answered. Getting the right installer and understanding every detail can make all the difference. This guide will give you the key things to ask so you can make a smart choice, whether you’re in Cardiff, Swansea or out in the countryside of Wales. We’ll also mention how it compares to other options in England, Scotland and Northern Ireland, if you’re curious about what’s happening elsewhere.
What Type of Spray Foam Are You Using? Closed-Cell vs Open-Cell
One of the first things to ask your installer is whether they’ll use closed-cell or open-cell spray foam. These aren’t just fancy words – they really do make a difference:
| Type | Best For | Main Benefit | Drawback |
|---|---|---|---|
| Closed-cell | Roofs, walls, where moisture’s a problem | Tough, very insulative, stops water | More expensive, less flexible |
| Open-cell | Lofts, interior walls where breathability is key | Cheaper, good for soundproofing | Not water resistant, less dense |
If you’re not sure which type is right for your property in Wales, don’t be shy about asking. A good installer will explain why they’re picking one over the other and what that means for your home.
What’s the Spray Foam Insulation Cost – and What’s Included?
Spray foam insulation cost can be a bit confusing, as prices depend on how much space you’ve got and the type you choose. In Wales, you might pay anywhere from £20 to £50 per square metre. So, if you need the whole loft done, costs can add up. Be clear about what’s included:
- Is the removal of old insulation included?
- Will they clear out rubbish or tidy up after the job?
- Is the price fixed, or are there possible add-ons later?
Ask for a written quote and compare with what’s available in England, Scotland or Northern Ireland if you have friends there. Sometimes prices can swing depending on region and demand, so it’s sensible to check.
How Will It Affect My Home – and Is Spray Foam Insulation Worth It?
We all want to know if we’re getting value for money. Will your heating bills drop? Will it help with draughts or noise from the neighbours? Here’s what the benefits of spray foam insulation often include:
- Keeps the heat in during winter and out during summer
- Can lower energy bills by up to 30 percent
- Helps with damp and condensation problems, especially in older Welsh homes
- Good for soundproofing
However, if installed wrong, spray foam might trap moisture or even cause issues with getting a mortgage later. This is why it’s important to use someone who knows what they’re doing and is happy to answer all your questions. Make sure your installer is approved, has experience in local homes, and can show you work they’ve done before in Wales or even across the border in England.
Are There Any Drawbacks or Warranties?
No job is perfect, so a trustworthy installer will talk you through any downsides. Some things to watch for:
- Spray foam can be messy if not done right
- Some mortgage lenders can be picky about it, especially closed-cell in roofs
- If there’s a leak afterwards, repairs are trickier than with other types of insulation
- Not all products are the same-check the warranty and what it covers
Ask about guarantees, and don’t be afraid to ask for references from other homes in your town, whether you’re in Wrexham, Newport, or up in North Wales. Knowing someone nearby has had a good result can be a real comfort.
Spray foam insulation could be just what you need to keep your home snug and save money on heating. But it pays to ask the right questions, compare what’s on offer, and make sure you understand what you’re getting. Whether you’re in Wales or looking further, always take the time to choose wisely so you’ll be happy for years to come.
