Building a house in Besta, Dorocell, Foamsystem, Isoleca or other?

[Jesper_Valfridsson]

Hello everyone,

I am going to build a house. I will do most of the work myself.
I have extensive experience with houses and construction. This will be my fifth house.

I would just like to hear some opinions on materials and prices.

I am considering building the house with one of the following solutions/materials:
Besta http://www.besta.se/
Dorocell http://www.dorocell.se
Foamsystem http://www.foamsystem.se/
Isoleca-block
Lightweight concrete blocks
another option (please suggest)

What do you think about the different options?
Advantages/Disadvantages
Anyone with experience building a new house with any of them?
Price, which is the most cost-effective option?
etc.

Very grateful for lots of opinions, tips, and ideas.

Regards,
Jesper

Check out Lammiblock: http://www.lammistenhus.se/sida1_2.php?s1=1
They have concrete on the outside and inside, with foam insulation in the middle.
Provides good thermal inertia inward and a stable/robust exterior.

Have you looked at Sundolitt kub?
Like LEGO pieces that you fill with concrete when the walls are reinforced and ready.
www.sundolitt.se
We are working on a house with this material and are satisfied.
Best regards, Lotta

Hi Jesper,

I'm on the same page as you with DoroTherm and Besta Block. I've been searching for sensible materials myself for a long time. We are going to build our 3rd house and are making it a passive house.

How has it gone for you, have you started yet?

Best regards,
Cynkan

I have built with Besta and it was great. Easy and smooth, weighs nothing so you don't wear yourself out. A frame can be erected in a day if you have a couple of people.

What did you pay per/m2 wall?

You have quite a good range of potential materials...

A friend of mine built with Besta about 3-5 years ago (depending on whether you mean construction start or end ), he seems to be satisfied all the way.
However, he hasn't built any other house, so reference objects are lacking.

His heating costs are surprisingly low, I wonder, for instance, if he really changes the air in the house 12 times a day.

He added an additional 95mm + 95mm insulation on the inside, as an installation layer and extra insulation.

He and a few friends raised the entire first floor of the house in 1-2 days; the next day the gable ends were completed, then glulam beams at the ridge and roof rafters, then roof sheathing.
I'm not 100% sure, but it was weather-tight in less than 2 weeks. All done by amateurs... , meaning no prior construction experience.

I can inquire if you have any specific questions.

Hi Jesper,

It sounds like your friend made the right choice by insulating the inside with 2x95mm. Ventilation is, as you say, very important, and even more important is to retain the heat in the house rather than just sending it out to the birds.

What seems interesting now with the Besta blocks is hearing a bit from people like your friend about any disadvantages they've experienced a few years after the build. It usually takes a few years for things to reveal themselves.

Things one might "regret" could include how windows have been caulked and sealed, with some saying you should use foam, while others advise against it because it contains too much air and doesn't provide any insulating function.

Feel free to ask if he "regrets" anything Something he would have done differently if he built today...

Best regards,
Cynkan

Hello everyone,
I am curious about more experiences of 'byggblockshus' from different manufacturers, feel free to share more experiences

Hi
same interest here too, I'm very curious about the pricing for these houses, especially Besta, does anyone know the price difference between their different wall thicknesses?

 

[Devilmind]

Does no one know what the square meter price is for Besta blocks? Preferably for both thicknesses. At least roughly... I'm extremely curious about this since I've just finished our house and am considering building a new, larger house

It's hard to say, Besta delivers complete structural kits with roof trusses and intermediate floors, and all houses are different depending on corner blocks and angles. I have built a Bestablock house myself and paid about 1450 SEK/m² wall surface (area for windows and doors included) 3 years ago. This also includes K-drawings for the structure and foundation.

I wonder if there is a big price difference between the different blocks from Besta? We are considering building with the passive house block and with ecogrund. That should be a good combination, I think. Does anyone know?

 

[Hålta]

Why have you ruled out ISORAST as a possible choice? This system provides, as far as I understand, the best insulation. But what is their major drawback??

 

[NybyggarPer]

Has anyone else considered using besta blocks with metal studs and then using 100mm lightweight concrete as the interior finish? This way, you eliminate wood (which can potentially mold) and create a bit more thermal inertia.
