Loft board flooring with insulation

[jonathon.beedie]

Hi,
You have to bare with me as am relatively new at this - just bought a house last year, which is a very new house (building was completed in October 2009). There is already ample insulation in the loft, which is very thick and rises above the joists. I have bought some loft boarding from B&Q, as I just want to lay it down to store a few things.

Now, when it comes to putting it down, would it affect the effectiveness of the insulation if I were to compress it down to fix the boards to the joists?

Thanks
Jay

That insulation should cover the joists with no visible holes.
Lofts are a valuable storage space it is unlikely that in placing a few items on the insulation you will ever notice the difference.

May I suggest that you visit one of the DIY stores and buy some sheets of polystyrene, you can uncover the joists, place the polystyrene across them and pile your stuff on the polystyrene.

Polystyrene will not compress and loading it will not effect its insulation properties it is a far better insulation than fibreglass.
