Thermal insulation materials for roof insulations

Thermal insulation on the roof is actually what keeps the house warm in winter and cool in the summer. Thermal insulating slabs will save you energy and  a lot of money that you are wasting to warm your building on the cold winter days or cool it in the summers.

Andreoy Insulation SA, through its many years of experience, gives you many choices of thermal insulating materials that are specially designed & certified for the thermal insulation of roofs with very low thermal permeability , with the goal of achieving  the fastest depreciation of your investment.

The correct type of insulating material (eg expanded polystyrene EPS, XPS polystyrene, stone wool,graphite  etc.) will be decided in cooperation and with the help of our civil engineers and our certified insulators , depending on the roof insulation system that will be selected and the desire cost of the roof insulation .

The thicker the thermal insulation material you choose for the thermal insulation of your roof, the better the thermal insulation you will have. Do not be afraid to upgrade your initial investment to get a better insulation result for your roof.


Therbobeto®, slopes and thermal insulation in the roof insulation

We have replaced the traditional heavy and non-thermal insulating materials (cement mortar, perlobeton, foamed concrete, lightweight concrete, etc.) with the Terbobeto® which we use exclusively.

Therbobeto® is a fiber reinforced lightweight concrete thermal insulation material, with amazing compressive and bending resistances that, due to its low weight, which contributes to the seismic protection of your building , at the same time it adds thermal insulation due to its certified low coefficient of thermal permeability (λ = 0,065).

The combination of these two thermal insulation layers in our insulations, solves the problems with black spots, moisture, molds and liquefactions on your roof.


Reliable and certified waterproofing roof systems

Waterproofing protects against rain, snow and humidity by ensuring the health of the roof insulation system or the waterproofing of the concrete slab.

The most common waterproofing solution for a roof insulation is the asphalt membrane. It combines reliability, long lifetime, resistance to low and high temperature , low maintenance costs and reasonable cost.

Andrew Insulation SA uses only certified & top-of-the-range bituminous membranes in the roof insulation that delivers and has thousands of satisfied customers to prove their reliability and durability over time.

Note:The asphalt membranes or waterproofing membranes are known by many as tar paper

On our waterproofing solutions, we added the Flex Thermo system, a material with high waterproofing performance, even for stagnant water on the roof since it has no joints and is only suitable for direct tile laying.

Finally, for our customers who want an alternative, innovative solution for roof waterproofing, we use premium quality sprayed polyurea applicationsThe roof-waterproofing solution with sprayed polyurea, offers excellent protection, long lifetime, high resistance to stagnant water, while also contributing to energy saving to cool your home, since it exhibits high thermal reflectance and is certified as a cold material.

We can offer many and qualitative options in the roof waterproofing so you can choose which suits you, according to the desired cost and the duration of lifetime

Pre work before the roof insulation

For most, the pre work that is required to insulate the roof (roof outlets, roof barriers, marbles etc.) seems to be an obstacle .

Τhe pre work has added financial cost and hassle, because it was necessary to coordinate many craftsmen (plumbers, builders etc.).

Not anymore! Andreoy Insulation SA undertakes with its own construction crews to relieve you by this hassle and is committed to knowing the prices of the pre works.

But if you want your craftsmen to work? Again no problem. We undertake, without any charge, to coordinate and, of course, to inspect whoever you will choose. The only thing you need to do is to give us access to your slab.

"We know you do not like the pre works ,that's why we undertake them"
