Description

GCS roof Insulation protects your roof space from heat buildup caused by radiant heat penetration, acting as a heat barrier to prevent all services within the roof space from drying out, cracking, and degradation due to UV and solar heat gain.

GCS Roof Insulation is a cost-effective insulation suitable for use in metal deck roofing systems in residential, commercial, industrial, and horticultural buildings where temperature variations are relatively high, and rain noise reduction is required.

• Effective thermal insulation; It has an R- Value of 27.40ft².F.h/Btu; RSi of 4.83m²K/W.
• Effective barrier against impact noise with a 28db contact noise reduction.
• Fire retardant.
• Is an effective moisture barrier.
• Maintains its thermal insulating properties over time as it does not collapse.
• It seals around fasteners, ensuring no leakages into the building from the roof.

The Cheapest Roof Insulation in Kenya

Despite having many heat-insulating materials available at Gypsum Ceiling Supplies, GCS roof insulation is the most affordable and easiest to install. These are the three most cost-effective roof insulation options in Kenya.

1. 3mm GCS Roof Insulation with Double Side foil Costs KES 180 Per Square Metre
2. 5mm GCS Roof Insulation With Double Side Foil Costs KES 210 Per Square Metre
3. 10mm Roof Insulation With Double Side Foil Costs KES400 Per Square Metre

GCS Roof Insulation 10mm

• Polyethylene Roof Insulation is double-sided reflective foil insulation, with a 10mm thick polyethylene foam core, that provides a radiant barrier, reflective insulation, and a moisture barrier. It protects your roof space from heat buildup by acting as a radiant heat barrier, preventing services within the roof space from drying out, cracking, and degrading due to UV and solar heat gain.
• It is a cost-effective insulation that is suitable for use in a metal deck roofing system in residential, commercial, industrial, and horticultural buildings where temperature variations are moderately/relatively high and where there is a need to reduce the disturbing rain noise.

Benefits of GCS Roof Insulation

• The insulation adds more lifespan to your ceiling system. For example, it can protect a gypsum ceiling from cracking caused by excessive roof heat.
• GCS roof Insulation foam is a product made of many tiny closed-cell globules sealed off from each other. Polyethylene foam is an excellent insulator of heat.
• GCS roof Insulation protects your roof space from heat build-up due to radiant heat penetration. PE roof insulation acts as a heat barrier, protecting all roof services from drying out, cracking, and degrading caused by UV radiation.
• GCS Roof Insulation is a cost-effective insulation that is suitable for use in a metal deck roofing system in residential, commercial, industrial, and horticultural buildings where temperature variations are moderately/relatively high and where there is a need to reduce the disturbing rain noise.
• GCS Roof insulation is widely used to insulate iron sheet roofs for residential, warehouses, supermarkets, hospitals, and much more. If installed correctly, PE foam reduces heat by 98%. The double-sided reflective foil helps in reflecting radiant heat

Frequently Asked Questions about GCS Roof Insulation

• Temperature – On average, a temperature drop of 7°C is easily achieved
• What is the percentage energy savings attained by using the PE roof insulation? – A reduction of 30% – 40% on energy cost is achieved where Air Conditioning units are in use.
• Does GCS Roof Insulation reduce rain noise? – Yes. The 10mm reduces contact noise (e.g., rain noise) by about 19dbs
• Does GCS roof insulation collapse with time? – It does not collapse with time; it maintains its structure/form over time.
• How does GCS Roof Insulation work? – It reflects the solar radiant heat and blocks heat transfer through conduction and convection.
• Can nails or screws piercing through the Insulation damage it? – It seals around nails once pierced through.
• Can the Insulation be laid directly on the Roof purlins? – It is laid on the purlins and given a small sag.
• What is the standard thickness/size of PE Roof Insulation? – PE Roof Insulation is available in 3 different thicknesses depending on your application.
• What is the lifespan of Polyethylene roof insulation? – It is long-lasting and lasts at least forty years.
• Does the reflective film delaminate or peel off? – PE Roof Insulation does not delaminate or peel off with time.
• Can GCS Roof Insulation be installed on an existing roof? – Yes, it can. The insulation is laid below the purlins and supported by galvanized GI wire strainer wires or galvanized mild steel plates. An overlap of approximately 100mm is recommended during installation.
• What thickness of insulation is needed? – This depends very much on the height of the roof from the floor and the operational temperature of the area to be insulated. In addition, the insulating effect increases with the product’s thickness.
• How is your product better than alternatives in Kenya? – Product quality, service, and technical back-up have ensured that our roof Insulation remains one of the brand leaders in Kenya. We maintain a strict protocol that ensures all products manufactured meet the specified requirements for each grade. In addition, our insulation bears the KEBS quality mark, confirming it meets established product standards.

How To Install GCS Roof Insulation

It is very easy to install the GCS roof insulation. You can install before or after fixing the iron sheets. The best practice is to install insulation before installing iron sheets. Doing so will significantly reduce labor and other expenses.

The requirements needed to install the GCS Roof Insulation are;

• The insulation sheet, i.e., 3mm, 5mm, or 10mm
• Roof Screws Self-Drilling with Washer
• Roll of Galvanized Binding
• Silicon Adhesive or Conta Glue
• Steel Nails
• Aluminium Insulation Tape

Procedure 1 (Iron Sheets not Installed)

If you have not yet fixed the iron sheets, tie the galvanized wire from one end to the other, leaving a gap of about 200 cm between centers. Spread the insulation sheet as you screw the iron sheets in place. Please don’t tighten the insulation; instead, allow a 50mm air gap between the insulation and the iron sheet.

Procedure 2 (Afterthought. When Iron sheets are already fixed)

You don’t need to worry if the iron sheets are already fixed. The insulation can be installed on the underside of the roof. Two people should work on this installation. Place the insulation sheet on the purlins, then, while holding it in place, use a self-drilling roof screw with a galvanized sheet strip to secure the insulation. Repeat the procedure, allowing a 50mm overlap between sheets. Finally, tie the galvanized wire from one end to the other to provide support. Use the contact adhesive and the aluminum tape on the joints.
