Mr Quyen - Santiago. Posted 13/11/2026
A Santiago ASA/PVC tile sheet gives a Bruneian house a tiled roof at about 5.4 kg per m², with no metal to rust; in Santiago tests the space under it stays 6 – 8 °C cooler than under bare metal sheet and rain noise is about 80% lower. A single-storey 11.5 × 9 m house with a gable roof takes 26 sheets of 5.475 m, about 142 m. Made in Vietnam, it can enter Brunei with an ASEAN Form D or under CPTPP.

What does a house roof in Brunei have to cope with?
Heat all year, humid air and heavy rain, often in short, hard bursts. Many houses in Brunei have metal roofing, and owners know the trade-off well: it keeps the water out, but the rooms under it are hot in the afternoon, a storm on the roof is loud enough to stop a conversation, and after some years rust starts at the laps and around the screw holes.
People searching for "atap rumah PVC" or "bumbung rumah PVC" usually want a roof that looks like tiles without the weight and the many loose pieces of a tiled roof. That is what the tile sheet is made for.
What is the Santiago tile sheet?
It is a long sheet with a Spanish-style tile profile, made in Vietnam from four co-extruded layers with no glue: an ASA top layer that carries the colour and blocks UV, a virgin PVC layer, a PVC core and a milky-white PVC base that faces the room. The material is virgin, not recycled, and there is no metal in it.

Which roof colour for a Bruneian house?
Five colours are standard: dark grey, red, blue, orange and chocolate. Green, white and purple are made to order. Chocolate and dark grey are the quiet choices on white or cream walls; red and orange give the classic tiled-roof look. The ridge cap, hip ridge, ridge terminals, eave sealing tile, wall flashing and ASA screw caps come in the same colours.
Choose from a real sample, not a photo. Samples are free (the buyer pays the courier); hold one against your wall in daylight before you decide.
How many sheets for a single-storey house? A worked example
Take a single-storey house of 11.5 × 9 m with a gable roof. The ridge runs along the 11.5 m side, the slope is 30% (about 17°), the eaves overhang 0.6 m and each gable end overhangs 0.3 m.
| Step | Working | Result |
|---|---|---|
| Ridge height above the eave line | 4.5 m half-width × 30% | about 1.35 m |
| Face length along the slope | (4.5 m + 0.6 m) × 1.044 | about 5.32 m |
| Sheet length | 5.32 ÷ 0.219 = 24.3, round up to 25 steps; 25 × 219 mm | 5.475 m (the extra 15 cm goes into the eave) |
| Sheets per face | (11.5 m + 2 × 0.3 m) ÷ 0.96 = 12.6, round up | 13 sheets, covering 12.48 m |
| Sheets for the roof | 13 × 2 faces | 26 sheets, about 142 running metres |
| Roof area | 12.48 m × 5.475 m × 2 | about 137 m² |
| Screw sets with ASA caps | 137 m² × 4 – 5 per m² | about 550 – 680 |
| Ridge and eaves | Ridge length and both eaves | 12.48 m of ridge cap, 2 ridge terminals, 2 × 12.48 m of eave sealing tile |
| Sheet weight | 137 m² × 5.4 kg | about 740 kg |
142 m is a small part of the 5,000 m in one export container, so a single house is normally supplied through a Bruneian dealer or a builder who imports by the container. The price is quoted per order in writing.
Bringing roof sheets into Brunei: Form D or CPTPP
Brunei and Vietnam are both in ASEAN and both in CPTPP, so Santiago roofing (HS 3925.90.00) can enter Brunei with an ATIGA Form D or a CPTPP proof of origin, which Santiago provides for each container. Your customs broker picks the better route and confirms the rate.
What does the builder need to know?
Purlins go less than 700 mm apart: 440 or 660 mm for the tile sheet, one under the foot of a tile step, with the top purlin 15 – 18 cm below the ridge. Keep the slope between 20% and 45%. Pre-drill 6 mm holes and fix 70 mm screws with ASA caps through the top of the wave over a purlin, 4 – 5 sets per m², never in the valley. Lap each sheet one wave over the next.
Santiago supplies the sheets and accessories and sends installation videos; it does not install. It publishes no wind rating for the sheet and holds no Brunei approval, so the builder or engineer designs the frame and fixings for the site, and the local authority decides on any approval. Every lot ships with a quality certificate (CQ) under ISO 9001:2015 certificate ICI-23087.D. For houses over water or near the sea, see our article on roofs for houses by the water in Brunei.
How do tile sheets handle tropical sun and heavy rain?
This one-minute short moves from red tile sheets going up onto a house to a flame test on a stack of sheets, then a blue warehouse roof under installation. A flame test is a demonstration, not a fire rating.

How does a tile sheet compare with metal and clay?
A one-minute short with English captions: Mr Quyen compares metal and clay roofs with Santiago ASA/uPVC tile sheets, first in the factory and then on finished red and grey roofs.

How tough is a 2.5 mm sheet? The truck test
A Santiago delivery truck drives over a blue ASA/PVC tile sheet and a blue corrugated sheet laid on the factory yard in Vietnam. It is a demonstration only; on a roof the sheet still needs purlins less than 700 mm apart.

CPTPP: lower import duty on roofing sheets made in Vietnam
Vietnam is one of the 12 member countries of the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP), together with Australia, Brunei, Canada, Chile, Japan, Malaysia, Mexico, New Zealand, Peru, Singapore and the United Kingdom. Santiago ASA/PVC roofing sheets and accessories are made in Vietnam (HS 3925.90.00), so buyers in these countries can claim the CPTPP preference when they import them.
- Lower or zero import duty. Each member cuts its tariffs on goods of Vietnamese origin under its own CPTPP schedule, and many tariff lines are already at 0%. Your customs broker confirms the rate that applies to HS 3925.90.00 on the day of import.
- Proof of origin with every container. Santiago prepares the CPTPP origin documents for each shipment, so the importer can claim the preferential rate at clearance.
- Advance rulings. Under CPTPP, an importer can ask its customs authority for a written ruling on tariff classification and origin before the goods ship, so the duty is known before the order is confirmed.
- Faster, more predictable clearance. CPTPP members commit to publish their customs rules and, where possible, to release goods within 48 hours of arrival.
- The same preference on every repeat order. As long as the sheets are made in Vietnam and the origin documents are in order, each new container qualifies again.
Duty rates and paperwork change by country and over time: check the current rate and the proof-of-origin form with your customs broker before you order.

Kepingan atap genting ASA/PVC Santiago memberi rumah di Brunei rupa bumbung genting dengan berat kira-kira 5.4 kg bagi setiap m², dan tiada logam yang boleh berkarat. Dalam ujian Santiago, ruang di bawahnya 6 – 8 °C lebih sejuk berbanding atap logam biasa dan bunyi hujan kira-kira 80% lebih perlahan. Rumah setingkat 11.5 × 9 m dengan bumbung bentuk A memerlukan 26 keping sepanjang 5.475 m.
Kenapa atap rumah PVC sesuai untuk cuaca Brunei?
Panas sepanjang tahun, udara lembap dan hujan lebat. Atap zink menahan hujan, tetapi bilik di bawahnya panas pada waktu petang, bising apabila hujan lebat dan lama-kelamaan mula berkarat di sambungan dan lubang skru. Kepingan Santiago dibuat di Vietnam daripada empat lapisan yang disemperit bersama tanpa gam: lapisan atas ASA yang membawa warna dan menahan UV, lapisan PVC asli (bukan kitar semula), teras PVC dan lapisan bawah PVC putih susu. Tiada logam di dalamnya.
