What is rafter insulation?
Because the whole roof slope, the gables and the party walls now have to be insulated, this costs much more than insulating the floor and saves less heat for the money. We check the roof underlay first: a breathable membrane and a felt with no ventilation gap need different build-ups to avoid condensation. More about rafter insulation.
- Rigid insulation between the rafters, joints taped
- Insulated plasterboard lining where specified

Questions about rafter insulation in Emsworth
Will I get a written quote for work in Emsworth?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
Can you visit Emsworth outside working hours?
Ask about early, late or weekend appointments when you get in touch, and we will tell you honestly what we can offer.
What do I need to do before you arrive in Emsworth?
Clear a path to the hatch and, if you can, move stored items away from the area we will be working in. Tell us about anything heavy or fragile.
Will it cause condensation?
It can if the build-up is wrong for the roof. Old bitumen felt needs a ventilation gap behind the insulation; a modern breathable membrane may not. We check before we design it.
Is insulating between the rafters better than the loft floor?
Not for saving energy alone. Insulating the floor heats less space and costs far less. Rafter insulation is the right answer when the loft itself needs to be warm.
