Doors through to conservatory

[StrangerintheNight]

We've currently got external grade uPVC doors between the living room and conservatory. They need replacing, and DH wants to buy glazed timber internal doors as he's seen some he likes the look of.

I'm really wary of losing heat and sound insulation, so should I insist on them being external grade doors, although I know it will be more expensive? Does anyone have any experience of this?

Thanks

From what I know, they have to be external grade to comply with building regs.

I would go for external grade for security purposes too - check your house insurance, you might find they need to be of a certain standard

In terms of security and heat retention, a conservatory is about the same as a tent or a garden shed, so external grade will be better, as well as compliant with BRs.

I think plastic doors look horrid. Wooden ones in your position will last well as they are protected from the weather. Modern frames wil have good draught-stripping. It is much easier to fit good locks and rackbolts to timber doors.
