Why loft insulation matters

Loft insulation is crucial for maintaining a comfortable and energy-efficient home. Insulation keeps your home warmer by reducing heat loss from your loft. This can lower your heating bills and cut your carbon footprint. Plus, in hot weather it can help to keep your home a little cooler, too.

At Viridian, we know how important it is to insulate your loft. We offer complete loft insulation packages starting at just £299. If you’re looking for a loft insulation company, then you can trust our transparent pricing and certified specialists.

The benefits of loft insulation

Properly installed loft insulation can:

  • Save you money: By reducing the amount of heat lost through your loft, you can save up to 20% on your heating costs.
  • Increase comfort: A well-insulated loft helps to maintain a consistent temperature in your home.
  • Reduce carbon emissions: Lower energy consumption leads to fewer carbon emissions, so your home will be more environmentally friendly.
  • Enhance property value: Energy-efficient homes can be more attractive to potential buyers. A higher EPC rating increases a property’s value. It also makes the property more appealing to potential buyers or tenants.

Using premium insulation

We use Knauf Loft Roll 44 which is a glass mineral wool roll. Knauf Loft Roll 44 is an insulation material specifically designed for use at ceiling level in cold lofts. It’s non-combustible, long-lasting, and made with up to 80% recycled materials.

Knauf uses a special bio-based binder. This binder holds the insulation fibres together, making the insulation easy to handle. This has the long-term benefit of making your loft a much more usable space, thanks to:

  • Soft, non-itch texture
  • Extremely low levels of dust during and after installation
  • No volatile chemicals (such as formaldehyde or phenol) that can cause irritation
  • Excellent resistance to mould compared to other products

Knauf’s ECOSE® Technology binder consists of natural and renewable materials. It uses 70% less energy to produce than traditional binders.

Fast and efficient installation

A well-insulated loft must have a total of 270mm insulation thickness. We design our comprehensive loft packages to provide this, either through our glass mineral wool product or PIR insulation. The aim is to achieve maximum efficiency and comfort for your home.

Our Platinum Package combines a package with extras. This lets us set a flexible price compared to others.

For this service, we install high-performance loft insulation using a two-layer system for maximum thermal efficiency. First, we place 100mm of glass mineral wool insulation between the joists. Then, we add another 200mm layer on top, crossing-laying over the joists. This gives us a total insulation thickness of 300mm.

Our Gold and Silver Packages offer fixed pricing and require raised boarding, for which we increase the joist height by 130mm. Our certified installers then use 100mm of PIR insulation with great thermal efficiency under the boards. This creates an air gap between the insulation and the boarding.

This process meets our gold standard and greatly reduces condensation risks. Plus, it ensures a consistent U-value and thermal efficiency across the entire loft. It provides superior insulation while maintaining a stable and well-ventilated loft space.
