Loft Insulation

Loft insulation for loft conversions

Loft insulation in loft conversions

Its very important that the correct loft insulation is used in a loft conversion. Building regulations dictate what type of insulation we have to fit as we have to make sure the ‘U Values’ or heat loss  factor is correct and the loft rooms are fire protected.

There are 3 main types of loft insulation we have to fit in a loft conversion to comply to these regulations.

Correct loft insulation

The 1st part of insulating your loft is to insulate the new loft floor. This loft insulation has to be thermal for heat loss, acoustic for sound transfer but mainly to achieve a 30 minute for barrier between the 1st to 2nd floors.

The next part of insulating your loft is to insulate the side walls, gable end walls and roof slopes with 2 different types of loft insulation.

We fit a rigid 70 mm foil backed insulation in between your existing roof rafters, maintaining a 50 mm air gap between your insulation and your roofing felt ( for ventilation purposes )

We then pull and fix a multi foil loft insulation roll over the top of the rigid insulation board to achieve the building regulations criteria for the ‘U Value’.

The above image shows our team fitting loft insulation to the roof slope in one of our loft conversions.

It is always recommended that you consult a specialist loft conversion company an experienced Architect  or your local Building Regulations Department when installing loft insulation as only certain products have the British Standard Certification required for loft insulation in loft conversions.
