question regarding new sliding door for front porch

dwiseman

Hi, I'm going to replace the sliding door on my front porch and was looking for some advice. The porch is south facing and the sliding door is flush with the front of the house, currently we have an old single glazed sliding door and the porch is quite cold at night and impacts the temperature in the front hall as the front door seal isn't great. As we like the front door we figured we would replace the sliding door and leave the front door as is. My question, finally, is should we go for a triple glazed sliding door or would a double glazed unit give us the same performance? I think the triple would obviously preform better but would it be noticeably different? thanks in advance for any advice or opinions!:)

consider eliminating any differences between existing floor level and inside porch if any exists so that level access can be provided by use of ramped access

Thanks, there is no difference in the floor heights. Any advice on the glazing? thanks.

It will stay so double or triple glazed. You don't heat the porch I assume so the thermal efficiency of the slider is not relevant in a practical sense.

There's your problem .

- The cold gets into the porch through the existing sliding door making the porch cold. Heat from the house gets through the front door and into the porch, but that heat is negated due to the amount of cold that gets into the porch through the sliding door and from there then into the hall. I'm not concerned about heat getting through the front door into the porch. What I'm trying to do is to stop the cold getting into the porch in the first place. That's why I'm replacing the sliding door with something more efficient. We rarely use the front door, all access is through the side door so the sliding door is closed 95% of the time. Does that make sense to you? Essentially the front door is for decoration and security in this case and I'm looking for the sliding door to do the job of keeping the cold out, the porch is flush with the house so it has no external walls.

You should be, as 4Sticks has already pointed out.

Can you explain why? Some of my neighbours have moved their front doors to the position where the sliding door is. Essentially I want to leave the front door where it is and fit a sliding door that would preform as well as a front door. Do I take it that you think this is impossible from your reply?

Most porches I test leak air like a sieve and this has very little to do with the porch door as they are generally constructed to be outside the thermal envelope. Your porch may well be different of course, but without inspecting/testing it, it is not possible to be more specific.

Perhaps ask your neighbours who have removed their front door about this.

Thank you for the explanation. If you were of the opinion that my porch was internal as opposed to external and the only leakage that could occur was through the sliding door. What, if that was your line of thinking, would you recommend in terms of glazing mick? Come on, you know you want to help me out here, fellow cork man and all that.....

As I said, without seeing / inspecting it, I cannot give any meaningful opinion or recommendation. Sorry.

Btw, I may well live in the rebel county, but I am in no way a cork man.;);)
