I already have some loft insulation — Do I need to install more?

If your loft insulation is 100mm (4") or less you would certainly benefit by having it topped up with another layer of 200mm. (Current recommendations are around 300mm.)

 

Which loft insulation material do you use?

Knauf Loft Roll 44. This is a lightweight, non-combustible glass mineral wool quilt designed for superior thermal and acoustic insulation.

​

How do you install the insulation?

If your loft requires two layers, we lay the insulation between the joists to a depth of 100mm and then add a further layer of 200mm across the joists. If you just require a top-up, we lay the insulation across the joists.

​

There are a lot of pipes in my loft. Will these need to be insulated too?

If the pipes have no insulation, the original insulation has deteriorated, or it is hessian based, then the pipes will need to be insulated.

​

How about the cold and hot water tanks?

If the tanks have no jackets or the original jackets have deteriorated, then the tanks will need new jackets.

​

Do I need to clear my loft?

Yes, if possible. However, if you are not able to clear your loft, we can clear it for you at an additional charge. You will be advised of this during the survey.

​

My loft is boarded or part boarded: will this cause a problem?

No. We can lay the insulation directly over fixed boarded areas.  We can also leave a section clear if you wish to retain this for storage.

​

Do you offer loft boarding?

We only fit small storage areas, platforms and access boards to water tanks and boilers. For part- or full-loft boarding, we recommend you use a qualified carpenter.

​

Will I need to add additional ventilation to my loft?

That depends on whether it currently has adequate ventilation. An increase in loft insulation can result in condensation or damp. If your loft requires additional ventilation, we will recommend Tile Vents or Soffit Vents are fitted by a qualified roofer prior to installation.

​

How much will the insulation cost?

This will depend on the size of your property and if there is any existing insulation.

​

How long will the installation take?

We complete most installations within one day. However, if your loft is very large or additional work is required then you will be advised of the timescale during the survey.

​

​

Do you remove my existing insulation?

We will assess this during the survey. Common reasons for removal include: Contamination via damp, condensation or water leak; infestation via rodents; insulation that has been torn, ripped up or moved multiple times and not relaid properly.
