How to Insulate Your Roof and Make it Usable

Unusable roof space?

If the attic has not been habitable up to now and is therefore not isolated, to make it a cozy attic, it should be started from the very beginning of the laying of the structural layers. The attic insulation contractors Oshawa will tell you what your options are.

The situation is similar to the isolation of an attic space in a new building with one major difference that we need to adapt and refine an already existing solution that most often surprises us with a lack of joints in the cladding and a layer of ventilation above them and / of secondary coating – foil. If the roofing is compromised, it is best to replace it with vapor-permeable film and vents for the roof linings.

In the samples below you can see this solution in two versions:

Sample 1:

  • Ventilated sloped roof – a gutter with joints over the beams
  •  Stone mineral wool
  • Insulation glass mineral wool
  • Active Steam universal adhesive tape
  • Roof insulation

Sample 2:

  • Ventilated sloped roof – no boarding over the beams
  • Vapor-permeable membrane + universal adhesive tape
  • Insulation stone mineral wool
  • Insulation glass mineral wool
  • Active Silk Barrier Universal Adhesive Bar
  • Roof insulation

If we do not intend to replace the roofing coating at present and there is no ventilation layer in the structure of the existing roof, it is possible to make changes to the roof on the side of the room and provide ventilation to the roof.

A solution of this type may be true and functional, but before its application it must be taken into account that after applying the heat-insulating layers of the required thickness the light height in the mansard will be reduced.

Sample 3:

  • Ventilated sloping roof with additional laths
  • Vapor-permeable membrane + universal adhesive tape
  • Insulation stone mineral wool
  • Insulation glass mineral wool Classic 037
  • Active Silk Barrier Universal Adhesive Bar
  •  Roof insulation

If you want to isolate the existing roof, but the bright height in usable space is small or you do not want to break the already well-built mansard interior, in this case the outside repair is an ideal solution.

The advantage of this renovation is its efficiency and the speed with which it can be made.

Sample 4:

  • Skid roof – thermal insulation on the outsid
  • Vapor-permeable membrane + universal adhesive tape
  • Insulation stone mineral wool
  • Insulation glass mineral wool
  • Active Silk Barrier Universal Adhesive Bar
  • Roof insulatio

Usable attic space?

If the attic space is already absorbed and the heat insulation is installed together with the necessary steam barriers, it is important to first check the state of the existing materials.

There is a judgment and decision, what will be the renovation and what materials will be done. If we consider that the existing materials are not so good or damaged, it is best to provide access and conditions for building a roof with a structure such as Sample 1 and 2.
