Remaking roof with a "cold" in the attic loft living

In addition to the topics describing the details of the construction of large country cottages on FORUMHOUSE very popular reports, the portal where users share their experiences of small alterations houses. In this article we'll show you how, with about 600 thousand. rubles and a great desire to provide your family with a normal housing, to remake an old house with a "cold" attic into a comfortable cottage with a habitable attic. Namely:

• How to extend the living space through the attic floor.
• How to properly insulate and reconstruct the old house.
• What is a double ventilated gap to the roof insulated, coated with metal.
• What are the features mounting a ventilated facade.

Increase the area of ​​the house due to the insulated attic

The situation faced by the users of our portal with the nickname Soboleff, is familiar to many people in our country. Baseline: There is a house built "from the fact that it was" in the days of the USSR. In fact - a former summer kitchen the size of 6x4 m, which eventually expanded into a single-storey house 8x8 m, an area of ​​about 60 square meters. m.

The walls are made of silica ( "white") brick. Masonry is poor. The rear gable walls, common with a neighbor. Foundation - bottles.

Despite the "schools", a sturdy house, no cracks. Therefore, the common advice of experienced builders, which is cheaper to demolish the old building and replace it with a new - not suitable. Especially because the budget is limited, and must live "here and now".

A user has attached to their own home bathroom 6 square meters. m. to clean the inside walls in the kitchen, replaced the old gas boiler with a modern wall "dvuhkonturnik". The result: it turned to equip the kitchen (14 sq m on the ground floor. m), child (20 sq. m), a bedroom (15 sq. m).

But to ensure that younger children more living space, Soboleff I decided to dismantle the old roof and to build on the second floor attic. This was compounded by the fact that supply high-grade (a stone) on the second floor of the weak walls and the virtual absence of a full-fledged foundation - is risky. Yield - erect a lighter skeleton attic.

Stages of the old house renovation

Soboleff (User FORUMHOUSE):

I decided to make an attic wall height of 1.2 m in the center of height from the floor to the ridge -.. 3.5 m are two children's rooms on the second floor of 16 square meters. m Roofing -. metal. Warming plan to do with rock wool. Inside walls 15 cm, the roof - 20 cm + kontruteplenie outside walls 5 cm.

Throughout the winter, after sitting in the calculations (the house began to remodel in 2013) with the beginning of spring the user started the alteration and renovation of the house, which has hired a team of workers.

Dismantling the roof, but leaving the old ceiling, which supports podporli because live in the house and removing the roofing material, the builders saw the sad picture.

Floor beams sagged.

As a heater filled concrete block.

Assess the "quality" of masonry can be on the next photo.

Removing all the trash from the "second" floor, the upper part of the walls decided to align due to the masonry and pouring Laying nets.

Soboleff

Old ceiling, I eventually make it out (in part) and to raise the initial height of 2.3 m and a height of ceiling beams of the second floor 2.6 meters. Gathering formwork under Laying nets of cut sheets SIR, builders laid into it "sixteenth" rebar, whereupon the studs inserted and filled concrete.

Moreover, concrete Laying nets covers only the front pediment and two side walls. On the rear wall (on the side neighbor) laid beam cohesive 3-boards 20X5 cm, which is fastened with Laying nets.

Laying nets must be performed one and inseparable loop.

The next step of - setting columns concreted bottom of a metal tube with a diameter of 15 cm, which are welded to 22th channels, laid on the "edge".

The channel brought joists (overlap) made from board 20X5 cm.

Logs are stacked at a distance of 0.5 m apart.

Thus, departures turned the right wing of the second floor, and expanded the overall floor area.

In the resulting "platform" laid board subfloor, which, like all the wooden frame members, treated with antiseptic and flame retardant.

Closing banner floor from precipitation, builders have begun to erect the walls of the second floor.

The frame further zashotsya OSB, 9 mm thick and, thus, provides its rigidity and resistance to wind load.

When used as a sheathing frame slab material (plywood or OSB) do not need jib.

Also left a doorway under the rough stairway size 1800h1800 mm.

How to make a double ventilated gap and features ventilated facades

After installation of truss construction and builders of the user at issue. Builders, as well as many "professionals", offered to mount directly on metal roofing batten laid on the rafters, which before it lay a waterproofing. Ie, without making mandatory ventilation gap, whereby moisture is removed from the roof space.

As a result of all the condensate will drip onto the crate.

Note that the user of this on his own, and builders have done everything right, stuffed kontrobreshotku from the bar and making ventzazor.

Also necessary clearance when mounted hinged ventilated façade, such as the user of a metal siding. The principle of operation of such a facade is as follows. Steam, seeking to get out from inside to outside the house, gets into the insulation, which is outside protected by a vapor-permeable water- and windproof membrane.

So that moisture can freely exit, between the siding and the insulation is left a gap of about 4-5 cm. Ventkanal unite with the ventilation gap, arranged under the roof covering. Due to the difference in height between the air entry point (the bottom wall is left as a gap) and the exit point at the ridge (not skate sutured tightly, and the gap is left, which closes the ridge lath) arises powerful thrust, and all the moisture from the construction deleted.

Despite the thorough and thoughtful approach Soboleff to the reconstruction of the house, there were no forced alterations.

Although between the waterproofing and roofing ventzazor have a width of about 5 cm, with the roof insulation bottom heater pressed against waterproofing. Builders say that, and so will come down, they always build, but I decided to remake this node and double-ventilation gap, so that moisture can go out and erode from the heat insulation.

The fact that the conventional waterproofing (anti-condensate) film, which is often used during installation of the roof, do not miss pairs. To provide an outlet steam that has entered the insulation, arranged double or ventzazor (between the insulation and waterproofing, and between the waterproofing and roofing), or, easier and more manufacturable mounted superdiffuzionnaya membrane.

Such material passes outwardly pairs, but does not allow condensation and moisture from the atmosphere to get into the insulation.

To ensure good ventilation insulation on the roof already mounted, the user entered in the following way. He took off his laid insulation, bought 20x30 mm cube, measured out in all the rafters from the top of 50 mm and a screwed bar. Every 500-700 mm from scraps CAP made cross and longitudinal strips. Now, after mounting a heater in a "crate" between the insulation and waterproofing a gap of 50 mm, through which erodes the moisture that can get into the stone wool, even when mounted below vapor barrier circuit.

Now pull the ridge is excellent, and the insulation is well ventilated.

Mounting the metal roofing, installing windows and finishing the main, the most time-consuming phase of the reconstruction, Soboleff independently engaged in the internal insulation of the attic and installation of heating and plumbing on the second floor.

Features warming house and debriefing

Also interesting is the process of external insulation of the house. On the walls by means of anchor-suspensions and fungi fastened heat insulation layer (rock wool) with a thickness of 5 cm.

Insulation closed vlagovetrozaschitnoy membrane, and then installed the profiles 60h27 mm, which provided ventzazor.

Besides the metallic profile bar also used 4x5 cm (vraspor for installing rock wool) and bar 2x4 cm (under ventzazor).

Then sheathed house siding, and he found "his face".

Soboleff

Insulate the attic, I moved to the second floor all the tools. At the top of the heat and light. Dial knowledge on our website and proceed to installation inzhenerki, sewer and finished attic. I wish you all good luck!

At the end of this article we present a budget for Reconstruction (prices for 2013). So:

• The initial material costs (wood, OSB, metal, vapor barrier and vlagovetrozaschitnye film, hardware) - 250 thousand. rub.
• Labor remuneration of workers (a team of 3 people). Workers dismantle the old roof, poured Laying nets, set the supporting pillars, erected frame, made lining attic OSP, partially warm the house, we put the rafters and installed metal roofing - 250 thousand. rub.
• Additional costs for the purchase of metal siding, fixing elements, insulation and fixing -100 thousand. rub.

Total, excluding further finishing and installation of all engineering systems that the user installs their own, 600 thousand was spent on reconstruction. rub.
