new garden room questions?

[Pilatus]

We are replacing a conservatory with a garden room (approx 6mtr x5mtr),which can also be utilised as a double bedroom by using a sofa bed,and we are having a shower room / loo built on to the end of the garden room. We wish the room to be cool in summer but warm in winter,the room faces west with no wind break to speak off ,so very exposed to westerly wind and rain. So your thoughts on the following questions will be helpful. I should add that "DEFINITELY" no wall space available for radiators,!!!!
Should we have the windows and roof lantern double or triple glazed (for keeping heat in ((winter)) ,heat out ((summer)) and noise of rain beating against windows and lantern?
Should we go for underfloor heating, (flooring to be engineered oak laid on cement floor)? What type of underfloor heating,electric or heated water?
We are considering a small wood burner to heat the room as well ,but that they may be overkill or should we forget the under floor heating in the room,but have underfloor heating in the shower room only.
Are fibreglass flat roofs any good,can you suggest any options,to fibreglass that do not leak !!!!
Thanks in advance for your thoughts etc.

Insulation insulation insulation, underfloor heating ,on a a 4 zone manifold,2 for main room i for shower room ,and 1 for duel fuel towel rad,lanterns are nice but noisey and hard to put curtains on.if you are having a flat roof then fibreglass is as good as anything.some of the new type aluminium windows are incredibly efficient,woodburner would be overkill if built to modern standards

Underfloor heating all the way - go wet and you can choose to heat the water however suits best - gas or electric. Wood burner, aside from the aesthetic, is not a great idea as you have to allow significant ventilation, plus it's hard to regulate the temperature & it's too easy to overheat if the building is to modern standards - you can't just turn it off! It costs a bit more, but using Pilkington K type glass can make a huge difference to the warmth of a room. Rain blatter will always be a problem with large areas of glass or composites - even triple glazing suffers as it's the unit being hit that makes the sound, the best units use differing glass thicknesses to help reduce it, but it's still there.

Don't have a glass roof, always be one thing or the other, too hot/cold.
We have just had a 5 degree fibreglass fake lead lookalike roof put on a utility room with mop-handle rolls to stiffen it, and it looks fine, I am assured it will outlast me.

Wow that looks great where does the strength come from on the gable end? Is it some kind of sunken goal post steel? Impressive design

There is a steel frame hidden in there ,the middle of the gable ,there is a post that goes up to ridge and then a another stell as a ridge support ,steel post on both corners with a wall plate supporting steel ,all 3 fixed back to house

no question re underfloor - I have electric in bathrooms / ensuites here and water in the rest of the house, the water system is the cheapest to run but both work well

wood burners don't work so well with underfloor and there will be no need re heat, only reason to have one is if you want the nice feel of a real fire or you have wood to burn to help keep heating bills lower

dont have a glass roof, good double glazing these days is better than triple glazing a few years back, double should be fine for all but extreme situations

 

[Wurzeetoo]

Looks great it's not often I'm taken back with design but that fits all criteria a light open room with high uninterrupted ceilings and a pillar less exterior how was the dwarf wall finished internally? Standard window cill or single skin?

 

[phillipe]

There was a capping made to fit over the pillars

This one is better

I am very envious,looks great .

 

[goodevans]

I have been thinking about that ,what I fancy is concertina doors with a double sided woodburner, so as in summer doors can be opened onto patio and then the wood burner acts as a chimnea if you get my drift

 

[suffolksmallholder]

Non Fumo in Stokenchurch have a selection of double sided wood-burners. http://www.fluesystems.com/
A well established co i've had dealings with for 25 years. Run by sensible folk & with good stock.

Many thanks for all your posts
Please can someone explain what type of glass,frames etc does one need to specify to window supplier , to get double glazed windows up to the standard of triple glazed windows. I ask the question as it has been mentioned on here and elsewhere that ,"really good double glazing is as good as cheap triple glazing".

Alumimium filled with insulation,plus argin filled k glass,will bring you very close

What mark up percentage do builders use on materials used on a project?

None ,get you4 own accounts and buy them yourself,you can get the same Discount's if you ask

For glass I use a co in Naaarwich called Ecoglass. They use Saintt-Gobain Glass to make the double glazed units; http://www.ecoglass.co.uk/products/glass-information/the-sealed-unit/
These are constructed to mimise cold bridging using composite material for the spacer bar & then put together in an argon filled environment using robitic machinery so each uint is properly filled & up to the A+12 rating you'd expect.
Pilkington's process is similar. One coating is done hot, the other is done cold & I can't remember which.
I'm no expert on aluminium frames so can't comment on these except they will more than likely complement your project as they can be anodised to almost any colour. Grey is the most common as grey is the in colour!

I am a fan of a particular plastic manufacturer, Duraflex plastichttp://www.duraflex.co.uk/ , along with a particular glass manufacturer Saint-Gobain.
I'm looking at overhauling a retirement bungalow for elderly rellies & although it is 150 miles from me I'm still going to try & use the same material suppliers.

Which brings me to the original point of this post coz I'm lookin right now & didn't know much about aluminium in doors or windows.
Duraflex also manufacture & are involved with aluminium extrusions so have a peep on their site & then ask who then makes doors & windows. http://www.duraflex.co.uk/aluminium-bi-fold-doors-homeowner.html
